1 Safety Notes

1 Safety Notes

Danger of scalding :

Make sure the settings allow temperatures exceeding 55°C (for thresholds of burning, see EN 563). Be sure to point out all possibly existing dangers (such as touchable surfaces, high temperatures of used water) to all persons operating this system.

Legionella heating :

If this function is activated, the water for use will be heated up to 65°C once a week for killing the legionella. (Danger of scalding!).

Permissible temperatures :

Based on the setting make sure that the permissible temperatures of the hydraulic plant will not be exceeded (e.g. floor heating, plastic pipes, etc. may be damaged due to excessive temperatures) even when the external temperatures are very low (e.g. -20°C).

Danger of freezing :

Make sure that the FUNCTION switch does not remain for longer periods of time in the MAINTENANCE or BOILER position during winter. The heating or boiler supply lines, respectively, may freeze up.

MAINTENANCE position: No antifreeze monitoring; BOILER position: The boiler supply lines may freeze up if no water is withdrawn and if the boiler has been charged. The boiler pump thus will not be activated and no water flows through the supply lines.

Battery meter :

The reading interval via M bus can greatly reduce the battery life for battery meters. It is recommended to use mains-operated counter. For battery meter a special software can be ordered.

CAUTION:

To disconnect the unit from the mains, use the all-polar switch on the part of the builder.

Only a qualified expert must open the unit.

The unit is completely maintenance-free.

Care must be taken that a proper ground and a circuit protector for feeding according to the national and local regulations have been provided!

3.3 Room remote control HMI

The SCHNEID-HMI (Human Machine Interface) is a in-room remote control with touch screen. It allows easy and fast access to the most important parameters of the scheme. The permanent communication with the control unit ensures a visualization of the current sensed values as well as the current operating status of the individual control components.Furthermore, the SCHNEID-HMI can also be used as a custom visualization and control element in grid control arrangements. For this purpose, the HMI is installed directly into the cabinet door. The display is available in different sizes and resolutions, depending on the customer's request. Through an internal recording function logging of different values is possible.

4.4 Speed-regulating module

There are 2 different speed-regulating modules. The first one is equipped only with one speed-regulating output, whereas the second one is equipped with two speed-regulating outputs. These 2 modules are distinct by the black semi-conductor relay.

Speed-regulating module with one output Speed-regulating module with two outputs

The additional module is equipped with a speed-regulating module controlled with half-waves.When switching off any one of the numerous half-waves per semi-conductor relays, the rotational speed will be controlled on ten stages from 0% to 100%. The frequent switch-on will always be done in the zero passage of the voltage, whereas the switch-off is done in the zero passage of the current.This results in a harmonious behavior of the rotational speed as well as in a very long life, since voltage surges will be avoided.The module of the speed-regulating device is mainly used for controlling small on-phased ventilators and pumps.The loading capacity of the output is limited to 5A. The maximum power of the connected motor should not exceed 300VA (considering the starting current).

4.8 COM Base

The allocation of the terminals A1-A4, B1-B4 and C1-C4 is varying depending on the plugged communication module, or some modules can also be directly wired to the plug-in card (e.g. USB module), respectively.

The sub communication to the extension controllers can be made without Bus module, if the three jumpers are provided on the module port C. The terminals C1-C3 are wired, whereas C3 is directly connected to all sub controllers, and C1 and C2 are cross-jointed once on the departure of the master controller. Refer to page 30 “COM C sub communication”.If the distance to the sub controllers is longer than 10m it is recommended to use a RS-485 module for this purpose. If a module is used, no cross-jointing will be necessary, and the jumpers must be removed. Refer to page 30 “COM C sub communication”.

The 30VDC supply terminals can be used to cover small voltage supplies, or be used by a Schneid engineer as an external supply for Mbus selection after restructuring, respectively.

If the supply is used as such, the power consumption of the supplied electronic components must not exceed a certain power consumption depending on the number of connected Mbus devices:

DI8 Module


4.8.4.3 CM08-BT Modul (Bluetooth)Using this communication modul, die controller is able to send data over short distances by radio technology (WPAN).

The communication module SCHNEID-CMM-CM08-BT is only suitable for the following componets:SCHNEID Module Controller MR08, Communication Base Module CM08 and later, Controller Version 8.19 and later.

Full details for installation, settings and the app can be found in the technical documentation “Bluetooth” (www.schneid.at/downloads).

Settings on the controller:Control the controller software (version 8.19 or higher) and if necessary, update. The control takes place by pressing and holding the "ESC" key.If you need an update, contact the operator of your system.The Bluetooth module has to be stuck in slot "COM C" and the Jumper J1-3 must be removed.The module will now start the initialization. (This takes about 30 sec).

Mounting the antenna (depending on type; screw or magnetic):The antenna must necessarily be installed outside of the controller housing. The connection at the Bluetooth module has to be plugged.

Configuration on Tablet or Smartphone- Download and Installation of the Remote-App (www.schneid.at - downloads)

- Open the App and select: BT-connection dial- Select "Search" in the pop-up window.- The module appears with the following identification: CM08-BT-XX-x- During the initial start, there appears a request to enter a Pairing code 1234- After successful connection, the message "enter new PIN code” appears. Enter a new code and confirm with „OK". This serves to protect against unauthorized access by strangers and must therefore be adapted.

Variant with additional Subkommunikation:Should be even prepared a parallel sub communication with other controllers, note the following:

A Subkommunikation is only possible via RS485 interface. The BT module has this already integrated. For further controllers then a CM08-485 interface card must be used. The bus cable and the RS485 termination is carried out in accordance with an RS485 Subkommunikation.

4.8.4.4 CM08-RF Modul (Radio-Frequency)Mit dieser Modulkarte kann der Regler Daten mittels Funktechnik übertragen. Using this communication modul, die controller is able to send data up to 40km by radio technology.

Full details for installation and settings can be found in the technical documentation “Radio Frequency” (www.schneid.at/downloads).

There are three variants of this plug-in-card:- Typ1: BG-CMM-CM08-RF1-LP (low power)with integrated RS485-interface for subcommunication between RS485 and radio.

- Typ2 (Standard): BG-CMM-CM08-RF2-LP (low power)with integrated RS485-interface for connection between outdoor-unit and controller.This module card uses wireless technology with mesh function to transfer data. Each existing module in the network is connected to one or more other. The information is passed from one module to another until they have reached the goal. The modules act simultaneously as a router and client. Using this technology, high coverage can be achieved and the network is self-healing and therefore very reliably. Should a connection be blocked or failed, the data is automatically redirected and the network is still operational. In addition to the 128-bit AES encryption independent subnetworks can be established by various Preamble or network ID's, which do not influence one another

- Typ3: BG-CMM-CM08-RF2-HP (high power)This interface card differs substantially by 250mW transmission power (compared to 25mW) and the related maximum range of 40km (free field) with respect to the LP version. However, the High Power Modules do not support MESH function and are subject to a duty cycle of 10%. This means that each module may occur a maximum transmission time of 6 minutes within an hour, if there is more, the module locks.

- To enter the basic setting on the service level, select the menu item “Basic setting”

6.8.2.1 Offset external temperature - Parameter 13The value can be configured in a positive or negative manner and will be added to the current external temperature. An offset will then become necessary if e.g. the sensor value has been tampered with due to a large line impedance (long wiring) or if it has been positioned unfavorably.

6.8.2.3 Temperature of initial operation at frost - Parameter 29.The temperature of the secondary initial operation to be used for regulation when the external antifreeze temperature falls below.

6.8.2.4 Antifreeze protection at external temperature - Parameter 30The external temperature can be set here, at which the antifreeze will be activated.

6.8.3 Operation parameter of transfer station





- To enter the operation parameters of the boiler press ESC to return to the main menu and select the menu item “District heating”

- The menu items under “District heating” contain the following parameters

6.8.3.1 Maximum power - Parameter 42The maximum power is that power, which is not exceeded by the transfer station even if the secondary heating requirement is higher. This function requires a heating counter and the „Power limit“–Parameter 54 page 40 must be activated.

6.8.3.2 Maximum return temperature at -10°C - Parameter 43The return temperature at -10°C forms the first point of a heating curve that depends on the external temperature and which results along with the return temperature at +20°C. The primary return temperature is limited to the value in accordance with the current external temperature.

6.8.3.3 Maximum return temperature at +20°C - Parameter 44The return temperature at +20°C forms the second point of a heating curve that depends on the external temperature and which results along with the return temperature at -10°C. The primary return temperature is limited to the value in accordance with the current external temperature.

6.8.3.4 Limit to return of boiler charge - Parameter 45When charging a boiler, the return temperature will be limited to the value set here in order to allow for a quick subsequent charging of the boiler/s.

6.8.3.5 Timer District heating-valve - Parameter 46This value is used for optimizing the regulation characteristics (part P) and identifies the time in seconds after which a change in the regulated quantity should be carried out on the valve. The increase of this value results in a more inert regulation of the primary valve.

6.8.3.6 Factor District heating valve - Parameter 47The factor is used for optimizing the regulation characteristics (I factor). The increase of this value results in a more aggressive regulation of the primary valve.

6.8.3.7 Factor District heating valve at limitation to power - Parameter 48This parameter will be activated only if the “limitation to power” – Parameter 54 page 40 has been activated and determines the intensity of the influence the change in power will have on regulating the primary valve. The higher the value, the more aggressive is the effect of the limitation of power on the FV valve. The default setting is 1.

6.8.3.8 Runtime District heating valve - Parameter 49The manufacturer-specific valve runtime must be allocated to this parameter. The manufacturer may specify the runtime of a valve, or this runtime can be queried and measured at the manufacturer, respectively. To measure, the time must be measured, which the valve takes to change from the completely opened state to the completely closed state (when externally controlled).

6.8.3.9 Increase of total required value - Parameter 50This parameter results in a total increase of the required value. If any heating circuits have been taken into commission, this value will be added to the heating circuit having the currently highest required value. The sum resulting from required value-HK + increase will result in the required value for the secondary side of the transfer station. If the value is set to 0, the secondary temperature of initial operation will be regulated on the required value of the respectively highest required value of the heating circuit.

6.8.3.10 Hand primary valve - Parameter 51Automatics: Automatic regulation by the FV valve.Hand CLOSED: Closes the FW valve.Hand OPEN: Opens the FW valve.Hand STOP: Stops the FV valve and leaves it on the position.

6.8.3.11 Return-concentration of heat exchanger - Parameter 52If a secondary return sensor has been connected, the return may also be limited with the concentration on the heat exchanger (difference in temperature primary to secondary). The concentration will be added to the secondary return and will result in the limited value for the primary return. The function is deactivated with the default setting “99°C”.

6.8.3.12 Limitation to power - Parameter 54This item will deactivate or activate, respectively, the function “Maximum power” - Parameter 42 page 35 “Factor District heating-valve limitation to power” - Parameter 48 page 35.

6.8.3.13 Valve synchronization – Parameter 839To select, if and when the valve positions of the primary valve are synchronized. For this purpose, the valve is once fully closed.

6.8.3.14 Supply pump only active with FW - Parameter 843 If this option is enabled, the system pump runs only when the district heating is in operation, not even if one of the parties requests heat. This is useful in some hydraulic variants with buffer.

© 2016 Seite 55


6.9.4.10 Required temperature of legionella - Parameters: 820(Base C), 822(Base D)

Before FW 8.18: 65°C, required value of top boiler sensor cannot be changed during legionella charging.

6.9.4.11 VL temperature of legionella - Parameters: 821(Base C), 823(Base D)

Before FW 8.18: 70°C, required value of charging temperature (VL required value) cannot be changed during legionella charging.

6.9.4.12 Legionella circulation - Parameter 825 (boiler 1), 826 (boiler 2)If this option is activated, at legionella function, the circulation pump is switched on. In addition, the legionella function is terminated only, when the temperature has been reached on Circulation return flow.

6.9.4.13 Start time legionella - Parameter 827 (boiler 1), 828 (boiler 2) For the legionella function can - independent of the loading times - a start time can be defined. If setting "24:00", the legionella function as previously is held by the first boiler charge of the day.

During the boiler charging time, this setpoint is decisive for one-off-switch of the boiler loading. If the boiler target temperature falls below the set hysteresis, the boiler pump is switched on until it reaches the desired temperature. Outside the charging period this is done by the boiler minimum temperature.To configure these parameters, select in the memory menu "Temp. top".

6.9.4.15 Tracking time of boiler pump Parameter: 88(Boiler 1), 98(Boiler 2)

Can be configured under the menu item "Mode". Specifies the time in minutes of the tracking of the boiler pump after a boiler loading.

6.9.4.16 Manual operation pump - Parameter 853Manual operation for boiler-pump Base C

6.9.4.17 Manual operation pump - Parameter 854 Manual operation for boiler-pump Base D

6.9.4.18 Way of charging the boiler Parameter: 89(Boiler 1), 99(Boiler 2)

This parameter refers to the charging behavior when charging at minimum temperature. This parameter refers to the charging behavior when charging at minimum temperature. The following 3 setting possibilities can be selected:

Until required temp.: When the minimum temperature is fallen below, the boiler will be charged until the required temperature has been reached.

Hold minimum temp.: When the minimum temperature has fallen below, the boiler will be charged until the minimum temperature has been exceeded by 2°C.

Blocking of charging time: Boiler charging periods during blocking time of any boiler charging. No charging will be performed during these periods, with the exception of an antifreeze charging. If the upper boiler temperature falls below 7°C, the charging will be performed until 12°C.

6.9.4.19 Boiler blocking Parameter: 90(Boiler 1), 100(Boiler 2)

This item can be configured in the menu of the respective storage under “Mode”. This parameter will make sure that the boiler will not be discharged by switching on the boiler pump in case of a too low initial operation temperature.

Exception:If the boiler is activated on its primary side, the secondary initial operation temperature will not be considered. See page 43, “Primary side of boiler”.

The following possibilities of setting can be selected:

1. No blocking of chargingThe function is deactivated; the boiler pump will immediately switch on when charging.

2. Until boiler temperatureThe boiler pump will switch on only if the secondary initial operation temperature or the primary RL temperature is higher by 5°C than the current upper boiler temperature. If the value falls below during a charging process, the boiler temperature will switch off after 1 minute.

3. Until charging temperatureThe boiler pump will not switch on before the secondary initial operation temperature is equal to the required value of the boiler charging temperature. If both sensors fall below this value during a charging process, the boiler pump will switch off after 1 minute.

Seite 56 © 2016


The reason for this blocking is if the heating is operated with 75°C, for example, the charging module may be overheated for a short period of time, which results in a calcification. This function does not exist in charging modules equipped with a mixer, since the mixer protects the charging module against calcification.

The total charging time is limited to 40 minutes. This period of time begins as of the first requirement for running and will not be restarted if the VL is fallen below and in case of a short-term switching off.

6.9.5 Operation parameter of circulation





– To enter the operation parameters of the boiler press ESC to return to the main menu and select the menu

item “Circulation”

– The menu items under “Circulation” contain the following paraneters

6.9.5.1 Times of circulationThe times of circulation indicate the period of time, within which the circulation pump is activated. The times of circulation are only for the circulation pump on base C or D.

6.9.5.2 Circulation HysteresisIf the switch-off temperature is underrun by this hysteresis, the circulation switches on again.

6.9.6 Operation parameter of differential regulator of solar

The normal design of the regulator is one without any additional module. The pump is switched ON/OFF via parameter 17 only.

A speed-regulating device module as an additional module allows for connecting 2 additional temperature sensors (upper buffer temperature, terminal 12 and solar initial operation temperature, terminal 18). Moreover, the solar pump will be regulated to a required initial operation at 60°C. If the measured value of initial operation is smaller than the required initial operation, the rotational speed will be reduced. It must be noted that the module will be connected instead of the third heating circuit module, and that the “speed-regulating device module” will be selected for the third extension module. For “Speed-regulating device module” see page 20, and for “Extension module 3” see page 50.

6.9.6.1 Maximum buffer temperature - Parameter 15This parameter limits the maximum temperature of the buffer on the buffer sensor.

6.9.6.2 Maximum collector temperature - Parameter 16This parameter limits the maximum temperature on the collector. The pump is switched off if the collector sensor exceeds this temperature.

6.9.6.3 Difference between buffer and collector - Parameter 17This item allows for setting the differential temperature between the buffer and solar sensor. The solar pump will be released, if this solar sensor has a higher value than the lower buffer sensor in addition to this difference. The hysteresis for switching off the pump is 3K.

6.9.6.4 Hand solar pump - Parameter 18As per default, the manual operation is set to 101%. This means the regulator controls the rotational speed automatically. If a rotational speed of 1-100% is set here, the solar pump will be controlled permanently with this rotational speed (manual operation).

6.9.6.5 Minimum rotational speed of solar pump - Parameter 19For setting the minimum rotational speed, which is used to control the solar pump, if it has been released.

6 Service Level / Configuration / Base B and Extension module

6.10Configuration of extension modules and base B (Heating circuits)

If no mixer has been connected, the initial operation temperature will be pre-regulated via the FW valve (45). It has to be noted that the maximum initial operation temperature of the individual circuits must not be exceeded when the boiler is being charged (floor heating). This required a correct configuration of the “Secondary water setting” on page 54 in order to switch off the respective circuit in case of charging.






– To enter the basic configuration in the service level, select the menu item “Configuration” and then “Single

Configuration”.

6.10.1.1 External releaseThe external release can be performed separately for each heating circuit.To release, a contact is connected between the signal input FBS of the remote control and GND of the respective heating circuit. If the contact is open, the circuit is released, whereas the circuit will be blocked when the contact is closed. (For terminal diagram, see page 16)This requires no other configuration!

6.10.1.2 Protective function of pumpWhen the heating circuit is not in operation, the heating circuit pump will be switched on for one minute each week on Monday at 6:00 P.M. in order to prevent any defect.

6.10.1.3 Base B (heating circuit 0) - Parameter 2This parameter determines the way of regulating the selected heating circuit.

The following possibilities of selection are available:0. Not available

This item deactivates the heating circuit; no regulating will be performed and there is no secondary requirement for the required value from this heating circuit.

1. Pre-regulated heating circuitThe heating circuit is regulated depending on the external temperature based on the configured initial operation temperature depending on the external temperature.See page 54: “Initial operation temperature at +20°C”, “Initial temperature at +5°C”, and “Initial temperature at -10°C”

2. Room temperature control without optimizationThe heating circuit is regulated depending on the room temperature, which has an influence on the current heating curve. See page 54 for “Heating curve”, page 54 for “Required room temperature”, page 55 for “Offset room temperature”, as well as page 55 for “Influence on room temperature”.

3. Room temperature control with optimizationThe heating circuit is regulated depending on the room temperature, which has an influence on the current heating curve. In addition, the lowering and heating times will be optimized, in order to reach the room temperature already in the beginning of the heating time.See page 54 for “Heating curve”, page 54 for “Required room temperature”, page 55 for “Offset room temperature”, as well as page 55 for “Influence on room temperature”.

4. Room thermostatThis setting will be used if the function of a room thermostat must be reached through a Schneid remote control. The external release function will be used for room thermostats, which are equipped with a contact for closing/opening.The setting under “Required room temperature” as defined on page 54 is regarded here as release temperature, in addition to or minus the hysteresis, respectively, for the thermostat regulator (see page 51).

5. Specification of external required value 0-10V

Seite 58 © 2016


The required value of the initial operation for the heating circuit is externally specified by a 0-10V analog signal. The connection will be made on the signal input of the remote control for circuit 0 on the base module. According to specification, the jumper must be set to 0-10V or be removed, respectively. The terminal diagram is shown on page 16, and for the “Final value at 0-10V specification”, see page 50.

- Heating circuit 0, control of initial operation with valve 45 and sensor 8 -The possibilities for selection, 1-5, in combination with Base A (2nd temperature control for Base B) will render possible a regulated heating circuit for Base B (see page 38).

6. Intermediate circuit of district heating without pumpThe interim circuit is between the transfer station and the remaining circuits. Its initial operation is resulting from the highest required initial operation of the remaining circuits. Apart from this, an increase in the required initial operation can be added to the biggest required initial operation which has been taken over.

7. Intermediate circuit of district heating with pumpThe supply pump switches on when a requirement for heating is received. The requirement will be given as soon as the secondary initial operation is greater than 0.

8. Return boost with valve 45A return boost or a boiler circuit, respectively, is possible in combination with base A. The temperature input 7 is the return sensor of the boiler and is regulated with valve 45 to the “minimum return temperature”. The temperature input 8 is the initial operation sensor of the boiler and regulates with the valve 45-if connected-to the current required value of the initial operation. The boiler sensor is used as temperature input 11, which allows the release for the boiler circuit, if the boiler sensor is higher than 5°C minus the return sensor. The release can also be performed by way of short-circuiting the boiler sensor.

6.10.1.4 Minimal return to boiler - Parameter 816If the boiler return temperature falls below this value, the mixing valve is gradually closed. If the temperature is higher, the mixer is opened and controlled by the flow temperature.

6.10.1.5 Extension module 1 (heating circuit 1) - Parameter 30. Not available

This item deactivates the heating circuit; no regulating will be performed and there is no secondary requirement for the required value from this heating circuit.

1. Regulated heating circuitThe heating circuit is regulated depending on the external temperature based on the configured initial operation temperature depending on the external temperature. See page 54 for “Initial operation temperature at +20°C”, “Initial operation temperature at +5°C”, and “Initial temperature at -10°C”.

2. Room temperature control without optimizationThe heating circuit is regulated depending on the room temperature, which has an influence on the current heating curve. See page 54 for “Heating curve”, page 54 for “Required room temperature”, page 55 for “Offset room temperature” as well as page 55 for “Influence on room temperature”.

3. Room temperature control with optimizationThe heating circuit is regulated depending on the room temperature, which has an influence on the current heating curve. In addition, the lowering and heating times will be optimized, in order to reach the room temperature already in the beginning of the heating time. See page 54 for “Heating curve”, page 54 for “Required room temperature”, page 55 for “Offset room temperature” as well as page 55 for “Influence on room temperature”.

4. Room thermostatThis setting will be used if the function of a room thermostat must be reached through a Schneid remote control. The external release function as defined on page 48 will be used for room thermostats, which are equipped with a contact for closing/opening. The setting under “Required room temperature” as defined on page 54 is regarded here as release temperature, in addition to or minus the hysteresis, respectively, for the thermostat regulator (see page 51).

5. Specification of external required value 0-10VThe required value of the initial operation for the heating circuit is externally specified by a 0-10V analog signal. The connection is made on the AIN module. Refer to “AIN module” on page 21 and to “Final value at 0-10V specification” on page 50.

CAUTION: For the extension modules, an own module will be required for this specification.

6. Regulated DHW charging moduleThe heating circuit 1 regulates the primary initial operation for the boiler on base C. For the correct boiler configuration, see page 41 item 5, “Regulated DHW charging module”.

7. DHW circulation pump for boiler 1 (base C)The circuit regulates the circulation pump. The heating times set for the circuit are regarded as circulation times (see page 53). The release temperature for the circulation pump must be measured on the initial operation sensor of the respective heating circuit module, and configured with the parameter “Switch-on temperature of circulation pump” (page 51).

8. Change-over valve for additional heat generatorsThis configuration enables the use of an independent heat supplier regardless of the district heating network (e.g. boiler, etc.). This configuration allows no function of an extension module as a heating circuit. The temperature input of the respective module receives its function as temperature sensor of the external energy source, whereas the output 1 of the respective module is able to switch a change-over valve. The regulation acts as follows: If the temperature of the external energy source is higher than the sum from the required initial operation temperature and the maximum initial operation temperature*, 1 switches on and the district heating valve closes. See page 56, “Generator switching”.

9. Requirement from additional heat generatorIf the temperature falls below the required initial operator for a certain period of time, an existing heat generator will be switched on (e.g. oil container). See page 56 for “Generator requirement”.

10. Intermediate circuit pumpThe intermediate circuit pump acts in the same way as the supply pump. It is activated only if the secondary required initial operation is higher than 0.

Analog to the heating circuit 1 on page 49, except of item 6 and 7.

6. Regulated DHW charging moduleThe heating circuit 2 regulates the primary initial operation for the boiler on base D. See page 40 item 4, “Regulated DHW charging module” for the correct boiler configuration.

7. DHW circulation pump for boiler 2 (base D)The circuit regulates the circulation pump. The heating times set for the circuit are regarded as circulation times (see page 53). The release temperature for the circulation pump is measured on the initial operation sensor of the respective heating circuit module and configured with the parameter “Switch-on temperature of circulation pump” (see page 51).

6.10.1.7 Extension module 3 (heating circuit 3) - Parameter 5

Analog to the heating circuit 1 on page 49, except of item 6 and 7.

6. Speed-regulating device moduleThe speed-regulating device module is activated only if the item “Heating boiler” or “Register boiler, solar” has been set on base C or D. For clamping on AOUT see page 20, “Speed-regulating device module”.

7. DHW circulation pump for boiler 1 (base C)The circuit regulates the circulation pump. The heating times set for the circuit are regarded as circulation times (see page 53).

6.10.2.1 Final value at 0-10V - Parameter 64If a heating circuit has been configured for the specification of the external required value (see page 48), this value will determine the maximum value in °C of the specification, that is, at 10V. The minimum value for 0V is 0°C. Therefore this value determines the temperature specification by the signal. The maximum and minimum temperatures remain further valid for this circuit.Entering a value of 100°C would mean a specification of 50°C at 5V, whereas entering a value of 70°C would mean a specification of 35°C at 5V:

T [°C] Initial operation temperature in Celsius degreesU [V] Voltage specification in VoltP64-A Parameter 64: Setting to 100°CP64-B Parameter 64: Setting to 70°CP64-C Parameter 64: Setting to 40°C

6.10.2.2 Duration of Party mode - Parameter 21This item is for setting the time specifying the duration of the party mode. After this duration has expired, the regulator will automatically return to the previously selected mode.

6.10.2.6 No lowering at night - Parameter 25This item enables the configuration of a gliding lowering at night which depends on the external temperature. The value set here corresponds to the external temperature, from which the required value of the initial operation should no longer be lowered (relates to the cold external temperature). The parameter “Complete lowering at night” indicates the upper limit.

RT Required room temperature

AT Current external temperature

P24 Parameter24: No lowering

P25 Parameter25: Complete lowering

The example shows a setting, with which no lowering will be effected below an external temperature of -30°C, and the set room temperature here is at 20°C. Starting from an external temperature of 20°C, the complete lowering, which has been set, will be effected (here: 8°C).

6.10.2.7 Hysteresis, thermostat regulator - Parameter 26This value provides the hysteresis, by which the switch-on or switch-off, respectively, of a thermostat regulator is delayed (see page 48). The circuit is released when the room temperature is lower than the required value (see page 54) minus the hysteresis. The circuit is switched off when the room temperature is higher than the required value in addition to the hysteresis (see page 54).

6.10.2.17 Periods of time of heating - Parameter 67This parameter offers the possibility of selecting the heating times, lowering times, heating and blocking times. The detault setting is “Heating times”. If the setting “Lowering times” is selected, the item “Lowering times” is now available and can be configured instead of “Heating times” (see page 53). The period of time 3 of the circuit will respectively be used as period of blocking.

6.10.2.18 Naming of heating circuit - Parameter 71This parameter enables the configuration of whether the naming of the heating circuits is activated or not. If a data network is existent, any naming set here can be shown in the display.

For controlling the room temperature or for the room thermostat, this value is regarded as an increase in the room temperature. If no room temperature sensor is connected, this value will be regarded as an estimated increase or lowering, respectively, of the respective room temperature. The change in the initial operation temperature depends on the adjusted heating curve. The setting is only for circuits without remote control.6.10.3.2 Daytime correction – Parameter 831-838The Daytime correction can be adjusted additionally to the General settings / FBR for each circuit individually.

6.10.3.3 Lowering operation - Correction of loweringTo set the lowering operation, turn the control button on the upper right once and then press an arrow key. The lowering operation is now indicated instead of the day operation.This value can be set from -8°C to 0°C and effects a permanent adaptation to the initial operation temperature of the heating circuits during a lowering operation. For controlling the room temperature or for the room thermostat, this value will be regarded as a reduction in the room temperature. If no room temperature sensor is connected, this value will be regarded as a reduction in the respective room temperature. The change in the initial operation temperature depends on the adjusted heating curve.The setting applies to all circuits (incl. for the remote control).

6.10.3.4 Heating circuit modeThis mode can be manually controlled regardless of which regulating type has been selected. The mode can be adjusted directly in the menu of the respective heating circuit and under the menu item “mode”.

The individual weekdays can be parameterized jointly for all days either individually or via the menu item “Heating time from Monday – Sunday”. Any later individual change (e.g. from Saturday and Sunday only) will still be possible.Only the respectively third period of time of each heating circuit will be regarded as blocking times.

6.10.3.6 Switch-off temperature of day mode Parameter: 101(HK0), 115(HK1), 129(HK2), 143(HK3)

If the measured external temperature for switching off (see parameter 34 on page 52) exceeds this value during the day operation, the respective heating circuit will be switched off (heating circuit pump OFF, mixed valve CLOSED).

© 2016 Seite 63


6.10.3.7 Switch-off temperature of lowering mode Parameter: 102(HK0), 116(HK1), 130(HK2), 144(HK3)

If the measured external temperature for switching off (see parameter 34 on page 52) exceeds this value during the lowering operation, the respective heating circuit will be switched off (heating circuit pump OFF, mixed valve CLOSED).

6.10.3.8 Required room temperature Parameter: 103(HK0), 117(HK1), 131(HK2), 145(HK3)

This parameter applies only for the heating circuits, where a Schneid remote control is connected and where the regulating type “Room temperature control” or “Room thermostat” has been adjusted. Depending on the current deviation of the room temperature from this value, the required initial operation of the heating circuit is reduced. The parameters “Day correction” as well as “Correction of lowering” will increase or decrease this value, respectively.

6.10.3.9 Initial operation temperature at an external temperature of +20°CParameter: 104(HK0), 118(HK1), 132(HK2), 146(HK3)

This parameter indicates the initial operation temperature of the external temperature at +20°C and is the first point of the heating curve made up of 3 points. See diagram on page 56.

6.10.3.10 Initial operation temperature at an external temperature of +5°CParameter: 105(HK0), 119(HK1), 133(HK2), 147(HK3)

This parameter indicates the initial operation temperature of the external temperature at +5°C and is the second point of the heating curve made up of 3 points. See diagram on page 54.

6.10.3.11 Initial operation temperature of external temperature at -10°CParameter: 106(HK0), 120(HK1), 134(HK2), 148(HK3)

6.10.3.12 Maximum initial operation temperature Parameter: 107(HK0), 121(HK1), 135(HK2), 149(HK3)

This parameter shows the upper limit of the initial operation temperature for the heating circuit. The required value calculated by means of the heating curve made up of 3 points or by the room temperature does not exceed this value. See diagram 54.

6.10.3.13 Minimum initial operation temperature Parameter: 108(HK0), 122(HK1), 136(HK2), 150(HK3)

This parameter shows the upper limit of the initial operation temperature for the heating circuit. The required value calculated by means of the heating curve made up of 3 points or by the room temperature does not exceed this value. See page 54.

6.10.3.14 Diagram of heating curveThis diagram includes all three temperatures of initial operation of the external temperature at +20°C, +5°C, -10°C as well as the maximum and minimum initial operation temperature.For the heating curve 1, only the initial operation temperature of the external temperature at 5°C has been changed (the default setting is 35°C; see Default heating curve).This diagram does not include the day and night correction (see page 53).

6.10.3.14 Secondary water setting Parameter: 109(HK0), 123(HK1), 137(HK2), 151(HK3)

The respective heating circuit will be switched off when the boiler is being charged. This setting is important for heating circuits, which e.g. supply a floor heating without mixture or which are fitted with plastic tubes, which must not exceed a certain temperature in order to avoid being damaged.

6.10.3.16 Regulating the timer Parameter: 110(HK0), 124(HK1), 138(HK2), 152(HK3)

This value is used for optimizing the regulating characteristics and identifies its interval in seconds after a change in the controller output has been performed on the valve. An increase in this value will lead to a more inert regulation of the heating circuit mixer.

Seite 64 © 2016


6.10.3.17 Regulating the factor Parameter: 111(HK0), 125(HK1), 139(HK2), 153(HK3)

This factor is used for optimizing the regulating characteristics (I factor). An increase in this value will lead to a more aggressive regulating of the heating circuit mixer.

6.10.3.18 Influence through room temperature Parameter: 112(HK0), 126(HK1), 140(HK2), 154(HK3)

This parameter determines how much the room temperature may have an influence on the temperature of initial operation.

6.10.3.19 Factor of room temperature control Parameter: 113(HK0), 127(HK1), 141(HK2), 155(HK3)

The required temperature of the initial operation of the heating circuit will be changed during room temperature control by means of this factor after integral behavior depending on the deviation from the required and actual room temperature.If the room is heated up from the outside (solar irradiation or additional heating), the required temperature of the initial operation can be reduced to zero. If the required temperature of the initial operation would be lower than 5°C after calculation, the heating pump will be switched off and not be switched on again before reaching +10°C.

6.10.3.20 Offset room temperature Parameter: 114(HK0), 128(HK1), 142(HK2), 156(HK3)

This value is added to the measured room temperature and thus has an influence on the regulation.This parameter is particularly used for correcting a room sensor, which is difficult to be positioned, and which is too far or too close to radiators, respectively.

6.10.3.21 Special circuit Parameter: 249(HK0), 250(HK1), 251(HK2), 252(HK3)

The heating circuit has an independent required temperature. This means that the heating circuit has no influence on the transfer station and on the secondary increase in the required value.

6.10.4 Operation parameter of generator switching

An existing heat generator is equipped with a temperature sensor. If the value indicated on the sensor is higher than the required initial operation plus the hysteresis of switching on, the regulator will switch to the external heat generator. The district heating stops supplying after switching. The switch-off will occur if the temperature of the generator is lower than the required initial operation minus the hysteresis of switching off.

– The menu items under “Generator” contain the following parameters.

6.10.5.1 Hysteresis, switching on - Parameter 37When the secondary initial operation temperature for the time span “Timeout of switching on” is lower than the required temperature minus the hysteresis of switching on, a requirement for the heat generator will be made.

6.10.5.2 Timeout of switching on - Parameter 39This parameter indicates how long the secondary initial operation temperature must be lower than the required temperature minus the “Hysteresis of switching on” in order for a requirement for the heat generator.

6.10.5.3 Minimum runtime - Parameter 40The minimum runtime enables a minimum heating time for the external heat generator. During this period of time, the external heat generator will be in operation once it has been released. The purpose of this switch is that the heat generator will need a certain time in order to supply any energy at all. Moreover, this will avoid a short start-up of the heat generator.

6.10.5.4 Only external energy in OFF/FS - Parameter 818The generator will be released when the selector switch on the regulator is set to “OFF/FS”.

6.10.5.5 External energy and district heating in parallel - Parameter 819When this parameter is set to “YES”, the FW will not be switched off when the generator is released.

12.1.1 Sorting the data

The following levels can be measured and tested by means of an oscilloscope:

The levels Rx+ and Rx- make up the inquiry of the regulators and must be on the relevant terminals.The recessive level (idle level) for Rx+ is 5V, whereas the prevailing one is 0V. The inverted levels apply to Rx-.

The levels Tx+ and Tx- make up the response of a regulator and it must be possible to measure them on the relevant terminals.The recessive level (idle level) for Tx+ is 5V, whereas the prevailing one is 0V. The inverted levels apply to Tx-.

The low-level 0V must not exceed 0.5V for any of the signals.

Tx+ (yellow), Tx- (turquoise); Test display

The high level 5V must not fall below any of the 4V signals.The signals must not be oscillating or contain any foreign harmonic vibrations, respectively (e.g. phase duration 20ms, when laying 230V-lines).

If one of these falsifications does occur, the wire shield must be checked or the wire must be shielded subsequently, respectively. A repeater module may also be used, if need be, in order to solve the problem.

Check the Mbus module of the Mbus device to be read. Check the data line on any defect. Check the terminal voltage between MBus+ and MBus- on 27VDC. Short-circuit the terminals MBus+ and MBus- → replace the lamps of Rx-

LED. MBus module.

Several heating counters (on one interface) are not read.

Check the power supply of the Mbus device to be read. Check the addressing (1-x) and the baud rate of the Mbus devices. Number of heating counters = 1 check (see page 35). B Check the baud rate of Com C (see page 36). Check the heating counter types (see page 35). Check the data line on any defect. Check the terminal voltage between MBus+ and MBus- on 27VDC. Short-circuit the terminals MBus+ and MBus- → replace the lamps of Rx-

LED. MBus module.

The Mbus device is operated by batteries and should be read within shorter cycles (setting for energy saving).

Allocate the address 2 to the heating counter and set the quantity of heating counters to 1 (see page 35).

In this configuration, the heating counter will be read out once per day at 00:00.

If there are several heating counters, the highest address will be allocated to the battery counter and the quantity of heating counters will be set to one number lower.(e.g.: 5 counters, battery WMZ: address5, quantity WMZ: 4)
