Product Description

Product design

3.2 Main function
The system control is a weather-compensated system control with an outdoor temperature sensor installed in the open air.
The system control is connected to the outdoor temperature sensor and the heat generator. The system control controls the heating installation and other connected components, e.g. the domestic hot water generation for a connected domestic hot water cylinder or the ventilation of a connected ventilation unit.
3.2.1 Heating
The outdoor temperature sensor measures the outdoor temperature and forwards the values to the system control. When the outdoor temperature is low, the system control increases the flow temperature of the heating installation. If the outdoor temperature increases, the system control reduces the flow temperature. The system control responds to the fluctuations in the outdoor temperature and uses the flow temperature to ensure that the room temperature remains at the desired temperature.
3.2.2 Cooling
The room temperature sensor measures the room temperature and sends the data to the system control. If the room temperature is higher than the desired temperature that is set, the system control switches cooling on.
3.2.3 Ventilation
Using a controlled exchange of air, the ventilation unit ensures that the living rooms are ventilated and aerated. The system control controls the air volume flow via the ventilation levels that are set.
3.2.4 Domestic hot water generation
A temperature sensor measures the temperature of the water in the domestic hot water cylinder and forwards the values to the system control. If the temperature lies below the set value, the system control increases the temperature in the domestic hot water circuit and therefore heats up the water to the set domestic hot water temperature.

1 Display 2 Wall base 3 Diagnostics socket

3.2.5 Circulation

The secondary return pipe is connected to the domestic hot water pipe and forms a circuit with the domestic hot water 2 cylinder. The circulation pump pumps the domestic hot water through the domestic hot water pipe, either continuously or on a time-controlled basis. This means that domestic hot water is available at the draw-off points.

3 3.3 Zones

4
4 Wall base cover 5 Selection button 6 Rotary knob

A building is divided into several zones if the heat demand differs between different sections of the building.
­ If underfloor heating and radiator heating are installed in a house.
­ If a house contains more than one independent residential unit.
If more than one zone is available, the system control controls the available zones.

Operating instructions 0020262548_01

3.4 Hybrid manager
If a heat pump and an additional boiler are connected, you can use the hybrid manager. If there is a heat demand, the hybrid manager picks the heat generator that is more costefficient. The hybrid manager decides which heat generator to operate based on the tariffs that are set in relation to the heat demand.
To ensure that the heat pump and the boiler can work effectively and in synch with one another, the tariffs ( Page 13) must be set correctly. If the tariffs are set incorrectly, this results in increased costs.
3.5 Frost protection function
The frost protection function protects the heating installation and flat from frost damage. The frost protection function monitors the outdoor temperature.
If the outdoor temperature
­ falls below 4 °C, the system control switches the heat generator on after a frost protection delay time, and brings the target room temperature to 5 °C.
­ rises above 5 °C, the system control does not switch the heat generator on but monitors the outdoor temperature.

Operation

4.1 Operating structure
4.1.1 Adjustment and display levels
The product has two adjustment and display levels. The end user level contains information and setting options that you require as the end user.

Note The competent person can set the frost protection delay time.
3.6 Preventing malfunctions
Ensure that room air can circulate freely around the sys-
tem control, and that the system control is not covered by furniture, curtains or other objects.
Ensure that all thermostatic radiator valves in the room
where the system control is fitted are fully open.

You can use the time programme to switch the system control between two implemented settings at specified times. To do this, create the required time periods in the time programme.
Setting the Heating time programme ( Page 12)
Setting the Cooling time programme ( Page 12)
Setting the domestic hot water circuit time programme ( Page 12)
Setting the Circulation time programme ( Page 12)
Setting the Ventilation time programme ( Page 12)
Setting the High tariff time programme ( Page 12)
You can create up to three time periods for each individual day and for predefined blocks (Monday – Friday, Saturday Sunday, Monday – Sunday).
When entering time periods for individual days or blocks, the last information that was entered always applies.
If you have not set any time periods, the system control uses the time periods set in the factory settings.

You can specify the temperatures (Day temp. heating and Set-back temp. heat.) in the Setting the Desired temperatures ( Page 10) function.
You can specify the times for the time periods in the Setting time programmes Heating ( Page 12) function.
Day temp. heating: 21 °C
Set-back temp. heat.: 16 °C
Period 1: 16:30­18:00
Period 2: 20:00­22:30
Within the time periods, the system control maintains the room temperature at the set Day temp. heating.
Outside of the time periods, the system control maintains the room temperature at the set Set-back temp. heat..

5.2.3.2 Setting time programmes quickly
If, for example, you require different time periods for just one working day in the week, first set the times for the entire block Monday – Friday. Then set the different time period for the working day.

If maintenance is required, the system control displays a maintenance message in the display.
To prevent the heating installation from breaking down and to prevent damage, you must pay attention to the maintenance message:
Observe the operating instructions for the unit shown. Only carry out the maintenance instructions that are de-
scribed in the operating instructions for the unit shown.
For all other maintenance instructions, inform the com-
petent person.
5.5.2 Fault message
Fault messages ( Appendix B)
A fault message with fault code (e.g. F.33) and the affected heat generator appear in the system control’s display.
Press the Reset selection button.

Troubleshooting faults ( Appendix B)

16

Operating instructions 0020262548_01

6.1 Implementing the setting if the heat pump fails
If the fault message Restricted operation/ comfort protection Inactive appears on the display, the heat pump has failed and the system control enters limp home mode. The back-up boiler now supplies the heating installation with heating energy. During installation, the competent person has restricted the temperature for limp home mode. You can feel that the domestic hot water and heating are not becoming very hot.
While you wait for the competent person to come, you can use the rotary knob to implement the following settings:
Inactive: The system control works in limp home mode; heating and domestic hot water become moderately hot.
Heating: The back-up boiler takes over the heating mode; the heating becomes hot, the domestic hot water is cold.
DHW: The back-up boiler takes over the domestic hot water mode; the domestic hot water becomes hot, the heating is cold.
DHW+heat.: The back-up boiler takes over the heating and domestic hot water mode; the heating and the domestic hot water become hot.
The back-up boiler is not as efficient as the heat pump, meaning that using only the back-up boiler to generate heat is expensive.
If you want to implement settings on the system control, click Back and the basic display appears in the display. After five minutes of no operation, the fault message appears again in the display.
