4 Description
41 Operating principle
411 Gasair setting
Air is sucked in by the fan and the gas injected into the venturiattached to the fan inlet The fan rotation speed modulates and adaptsto thermal energy requirements thanks to the temperatures measuredby the various sensors The gas and air are mixed in the venturi whichenables operation at a constant ratio The noise of the venturi isabsorbed by a silencer attached to its inlet The gasair mixture iscarried to the burner in the top of the exchanger guided by the pre-mix channel
412 Combustion
The burner heats the heating water circulating in the heatexchanger At a return temperature lower than around 55degC the fluegases cool down to a temperature lower than the dew point thuscausing the condensation of the water vapour contained in the fluegases in the lower section of the heat exchanger The heat releasedduring this condensation process (the latent heat or condensing heat)is also transferred to the heating water The cooled combustion gasesare evacuated via the combustion gas outlet flue The condensationwater is evacuated via a condensate trap

81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

4 Description
41 Operating principle
411 Gasair setting
Air is sucked in by the fan and the gas injected into the venturiattached to the fan inlet The fan rotation speed modulates and adaptsto thermal energy requirements thanks to the temperatures measuredby the various sensors The gas and air are mixed in the venturi whichenables operation at a constant ratio The noise of the venturi isabsorbed by a silencer attached to its inlet The gasair mixture iscarried to the burner in the top of the exchanger guided by the pre-mix channel
412 Combustion
The burner heats the heating water circulating in the heatexchanger At a return temperature lower than around 55degC the fluegases cool down to a temperature lower than the dew point thuscausing the condensation of the water vapour contained in the fluegases in the lower section of the heat exchanger The heat releasedduring this condensation process (the latent heat or condensing heat)is also transferred to the heating water The cooled combustion gasesare evacuated via the combustion gas outlet flue The condensationwater is evacuated via a condensate trap

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

4 Description
41 Operating principle
411 Gasair setting
Air is sucked in by the fan and the gas injected into the venturiattached to the fan inlet The fan rotation speed modulates and adaptsto thermal energy requirements thanks to the temperatures measuredby the various sensors The gas and air are mixed in the venturi whichenables operation at a constant ratio The noise of the venturi isabsorbed by a silencer attached to its inlet The gasair mixture iscarried to the burner in the top of the exchanger guided by the pre-mix channel
412 Combustion
The burner heats the heating water circulating in the heatexchanger At a return temperature lower than around 55degC the fluegases cool down to a temperature lower than the dew point thuscausing the condensation of the water vapour contained in the fluegases in the lower section of the heat exchanger The heat releasedduring this condensation process (the latent heat or condensing heat)is also transferred to the heating water The cooled combustion gasesare evacuated via the combustion gas outlet flue The condensationwater is evacuated via a condensate trap

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

4 Description
41 Operating principle
411 Gasair setting
Air is sucked in by the fan and the gas injected into the venturiattached to the fan inlet The fan rotation speed modulates and adaptsto thermal energy requirements thanks to the temperatures measuredby the various sensors The gas and air are mixed in the venturi whichenables operation at a constant ratio The noise of the venturi isabsorbed by a silencer attached to its inlet The gasair mixture iscarried to the burner in the top of the exchanger guided by the pre-mix channel
412 Combustion
The burner heats the heating water circulating in the heatexchanger At a return temperature lower than around 55degC the fluegases cool down to a temperature lower than the dew point thuscausing the condensation of the water vapour contained in the fluegases in the lower section of the heat exchanger The heat releasedduring this condensation process (the latent heat or condensing heat)is also transferred to the heating water The cooled combustion gasesare evacuated via the combustion gas outlet flue The condensationwater is evacuated via a condensate trap

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

41 Operating principle
411 Gasair setting
Air is sucked in by the fan and the gas injected into the venturiattached to the fan inlet The fan rotation speed modulates and adaptsto thermal energy requirements thanks to the temperatures measuredby the various sensors The gas and air are mixed in the venturi whichenables operation at a constant ratio The noise of the venturi isabsorbed by a silencer attached to its inlet The gasair mixture iscarried to the burner in the top of the exchanger guided by the pre-mix channel
412 Combustion
The burner heats the heating water circulating in the heatexchanger At a return temperature lower than around 55degC the fluegases cool down to a temperature lower than the dew point thuscausing the condensation of the water vapour contained in the fluegases in the lower section of the heat exchanger The heat releasedduring this condensation process (the latent heat or condensing heat)is also transferred to the heating water The cooled combustion gasesare evacuated via the combustion gas outlet flue The condensationwater is evacuated via a condensate trap

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

4 Description
41 Operating principle
411 Gasair setting
Air is sucked in by the fan and the gas injected into the venturiattached to the fan inlet The fan rotation speed modulates and adaptsto thermal energy requirements thanks to the temperatures measuredby the various sensors The gas and air are mixed in the venturi whichenables operation at a constant ratio The noise of the venturi isabsorbed by a silencer attached to its inlet The gasair mixture iscarried to the burner in the top of the exchanger guided by the pre-mix channel
412 Combustion
The burner heats the heating water circulating in the heatexchanger At a return temperature lower than around 55degC the fluegases cool down to a temperature lower than the dew point thuscausing the condensation of the water vapour contained in the fluegases in the lower section of the heat exchanger The heat releasedduring this condensation process (the latent heat or condensing heat)is also transferred to the heating water The cooled combustion gasesare evacuated via the combustion gas outlet flue The condensationwater is evacuated via a condensate trap

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption

4 Description
41 Operating principle
411 Gasair setting
Air is sucked in by the fan and the gas injected into the venturiattached to the fan inlet The fan rotation speed modulates and adaptsto thermal energy requirements thanks to the temperatures measuredby the various sensors The gas and air are mixed in the venturi whichenables operation at a constant ratio The noise of the venturi isabsorbed by a silencer attached to its inlet The gasair mixture iscarried to the burner in the top of the exchanger guided by the pre-mix channel
412 Combustion
The burner heats the heating water circulating in the heatexchanger At a return temperature lower than around 55degC the fluegases cool down to a temperature lower than the dew point thuscausing the condensation of the water vapour contained in the fluegases in the lower section of the heat exchanger The heat releasedduring this condensation process (the latent heat or condensing heat)is also transferred to the heating water The cooled combustion gasesare evacuated via the combustion gas outlet flue The condensationwater is evacuated via a condensate trap

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

4 Description
41 Operating principle
411 Gasair setting
Air is sucked in by the fan and the gas injected into the venturiattached to the fan inlet The fan rotation speed modulates and adaptsto thermal energy requirements thanks to the temperatures measuredby the various sensors The gas and air are mixed in the venturi whichenables operation at a constant ratio The noise of the venturi isabsorbed by a silencer attached to its inlet The gasair mixture iscarried to the burner in the top of the exchanger guided by the pre-mix channel
412 Combustion
The burner heats the heating water circulating in the heatexchanger At a return temperature lower than around 55degC the fluegases cool down to a temperature lower than the dew point thuscausing the condensation of the water vapour contained in the fluegases in the lower section of the heat exchanger The heat releasedduring this condensation process (the latent heat or condensing heat)is also transferred to the heating water The cooled combustion gasesare evacuated via the combustion gas outlet flue The condensationwater is evacuated via a condensate trap

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

4 Description
41 Operating principle
411 Gasair setting
Air is sucked in by the fan and the gas injected into the venturiattached to the fan inlet The fan rotation speed modulates and adaptsto thermal energy requirements thanks to the temperatures measuredby the various sensors The gas and air are mixed in the venturi whichenables operation at a constant ratio The noise of the venturi isabsorbed by a silencer attached to its inlet The gasair mixture iscarried to the burner in the top of the exchanger guided by the pre-mix channel
412 Combustion
The burner heats the heating water circulating in the heatexchanger At a return temperature lower than around 55degC the fluegases cool down to a temperature lower than the dew point thuscausing the condensation of the water vapour contained in the fluegases in the lower section of the heat exchanger The heat releasedduring this condensation process (the latent heat or condensing heat)is also transferred to the heating water The cooled combustion gasesare evacuated via the combustion gas outlet flue The condensationwater is evacuated via a condensate trap

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

4 Description
41 Operating principle
411 Gasair setting
Air is sucked in by the fan and the gas injected into the venturiattached to the fan inlet The fan rotation speed modulates and adaptsto thermal energy requirements thanks to the temperatures measuredby the various sensors The gas and air are mixed in the venturi whichenables operation at a constant ratio The noise of the venturi isabsorbed by a silencer attached to its inlet The gasair mixture iscarried to the burner in the top of the exchanger guided by the pre-mix channel
412 Combustion
The burner heats the heating water circulating in the heatexchanger At a return temperature lower than around 55degC the fluegases cool down to a temperature lower than the dew point thuscausing the condensation of the water vapour contained in the fluegases in the lower section of the heat exchanger The heat releasedduring this condensation process (the latent heat or condensing heat)is also transferred to the heating water The cooled combustion gasesare evacuated via the combustion gas outlet flue The condensationwater is evacuated via a condensate trap

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy

The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

4 Description
41 Operating principle
411 Gasair setting
Air is sucked in by the fan and the gas injected into the venturiattached to the fan inlet The fan rotation speed modulates and adaptsto thermal energy requirements thanks to the temperatures measuredby the various sensors The gas and air are mixed in the venturi whichenables operation at a constant ratio The noise of the venturi isabsorbed by a silencer attached to its inlet The gasair mixture iscarried to the burner in the top of the exchanger guided by the pre-mix channel
412 Combustion
The burner heats the heating water circulating in the heatexchanger At a return temperature lower than around 55degC the fluegases cool down to a temperature lower than the dew point thuscausing the condensation of the water vapour contained in the fluegases in the lower section of the heat exchanger The heat releasedduring this condensation process (the latent heat or condensing heat)is also transferred to the heating water The cooled combustion gasesare evacuated via the combustion gas outlet flue The condensationwater is evacuated via a condensate trap

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

4 Description
41 Operating principle
411 Gasair setting
Air is sucked in by the fan and the gas injected into the venturiattached to the fan inlet The fan rotation speed modulates and adaptsto thermal energy requirements thanks to the temperatures measuredby the various sensors The gas and air are mixed in the venturi whichenables operation at a constant ratio The noise of the venturi isabsorbed by a silencer attached to its inlet The gasair mixture iscarried to the burner in the top of the exchanger guided by the pre-mix channel
412 Combustion
The burner heats the heating water circulating in the heatexchanger At a return temperature lower than around 55degC the fluegases cool down to a temperature lower than the dew point thuscausing the condensation of the water vapour contained in the fluegases in the lower section of the heat exchanger The heat releasedduring this condensation process (the latent heat or condensing heat)is also transferred to the heating water The cooled combustion gasesare evacuated via the combustion gas outlet flue The condensationwater is evacuated via a condensate trap

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

4 Description
41 Operating principle
411 Gasair setting
Air is sucked in by the fan and the gas injected into the venturiattached to the fan inlet The fan rotation speed modulates and adaptsto thermal energy requirements thanks to the temperatures measuredby the various sensors The gas and air are mixed in the venturi whichenables operation at a constant ratio The noise of the venturi isabsorbed by a silencer attached to its inlet The gasair mixture iscarried to the burner in the top of the exchanger guided by the pre-mix channel
412 Combustion
The burner heats the heating water circulating in the heatexchanger At a return temperature lower than around 55degC the fluegases cool down to a temperature lower than the dew point thuscausing the condensation of the water vapour contained in the fluegases in the lower section of the heat exchanger The heat releasedduring this condensation process (the latent heat or condensing heat)is also transferred to the heating water The cooled combustion gasesare evacuated via the combustion gas outlet flue The condensationwater is evacuated via a condensate trap

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions

The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

8 Energy savings
81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind

81 Energy-saving advice
4 Keep the room in which the boiler is installed well ventilated4 Do not block ventilation outlets4 Do not cover the radiators Do not hang curtains in front of the
radiators4 Install reflective panels behind the radiators to prevent heat
losses4 Insulate the pipes in rooms that are not heated (cellars and lofts)4 Close the radiators in rooms not in use4 Do not run hot (or cold) water pointlessly4 Install a water-saving shower head to save up to 40 energy4 Take showers rather than baths A bath consumes twice as much
water and energy
82 Recommendations
The remote control is available in the following versions
4 Wire4 Radio
The setting of the control panel andor of the remote control has aconsiderable influence on energy consumption
A few tips
4 In the room in which the room thermostat is installed itrsquos advisednot to use thermostatic valve radiators If a thermostatic valve isused the valve must be fully opened
4 Completely closing and opening thermostatic valve radiatorscauses undesirable temperature fluctuations Open and closethermostatic valves in small steps
4 Lower the temperature to around 20degC This reduces heating costsand energy consumption
4 Lower the temperature when you air the rooms4 When setting a time schedule bear days when you are absent
and holidays in mind
