The room thermostats are available in three versions; two standard room thermostats with respectively dial or with LCD display and a programmable room thermostat with LCD display. All Room Thermostats are used for room temperature control in water based floor heat-

ing systems. By controlling room temperature in accordance with the temperature desired by the user the room thermostats provide optimal energy savings whilst upholding optimal thermal comfort in the room/ apartment.

Floor Heating Room Thermostats

Functions

Application

Room Thermostat, FH-CWT (Dial)By turning the dial to the desired set-point temperature optimal thermal comfort in the room is achieved. In addition to temperature the thermostat setting scale includes frost symbol allowing for minimal energy consumption while keeping the room from freezing. The thermo-stat is equipped with diodes which through the front cover will display a green light while the thermostat is ON but without heat demand and a red light when the thermostat is ON and there is heat demand.

Room Thermostats, FH-CWD (display) and FH-CWP (display and programmable) The thermostats with LCD display can in addi-tion to room temperature control be equipped with floor sensor thus allowing for control of maximum floor temperature and reducing risk of over heated and damaged floors. For specific maximum floor temperatures please refer to recommendations from floor suppliers.

Using the Frost Protection Mode instead of turn-ing the thermostat OFF completely may protect against damages due to low temperatures. The room temperature will be maintained around 5°C.

For the FH-CWP (programmable thermostat) two timer programs are available allowing tempera-ture setback or alternatively complete turning off the heat supply during selected periods without occupants in the room/ apartment.

The ON/ OFF Timer Function allows you to pro-gram the thermostat for one period with heating turned OFF and one period with heating turned ON per day. During the ON period the thermostat will regulate in relation to the set temperature and TIMER ON will be shown in the display. Dur-ing the OFF period, the heating is off, and TIMER OFF is shown in the display.

The Advanced Programmable Timer Function allows you to set a timer controlled program for automatic comfort temperature and energy saving lower setback temperature when standard room comfort temperature is not required.The Advanced Programmable Timer Function allows for 4 different periods / 5+2 days per week.
