Design of the product
Radio receiver unit
Radio outside temperature sensor
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 via the radio receiver unit. The system control radio-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.
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.
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.
Ventilation
Using a controlled exchange of air, the ventilation unit ensures that the living rooms are ventilated and aerated. The system controller controls the air volume flow via the ventilation levels that are set.
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.
Circulation
The secondary return pipe is connected to the domestic hot water pipe and forms a circuit with the domestic hot water 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.
Zones
A building is divided into several zones if the heat demand differs between different sections of the building.
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 cost-efficient. 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 16) must be set correctly. If the tariffs are set incorrectly, this results in increased costs.
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
Avoiding moisture and mold damage
In heavily insulated rooms that only allow a small exchange of air, moisture and mold damage may occur.

Messages
Maintenance message
Maintenance messages (→ Appendix C) 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 described in the operating instructions for the unit shown. For all other maintenance instructions, inform the competent person.
Fault message
Fault messages (→ Appendix B) A fault message with a fault code (e.g. F.33) and the affected heat generator appear in the system control’s display. Press the Reset selection button. Heat generator fault clearance? appears in the display. Press the OK selection button. Faults are cleared for the heat generator briefly
appears in the display. If the fault persists, inform the competent person. If you would like to see the basic display on the display again, press the left-hand selection button Back. You can read the current fault messages under Menu → Information → System status → Fault status. As soon as a fault message occurs for the heating installation, the setting level displays the value Fault list. The right-hand selection button has been assigned the Display function.
Overview of fault messages (→ Appendix B)
Implementing the setting of 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 backup 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 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 backup boiler takes over the heating mode; the heating becomes hot, and the domestic hot water is cold. DHW: The backup boiler takes over the domestic hot water mode; the domestic hot water becomes hot, and the heating is cold.
DHW+heat.: The backup boiler takes over the heating and domestic hot water mode; the heating and the domestic hot water becomes hot. The backup boiler is not as efficient as the heat pump, meaning that using only the backup 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 on the display.
Cleaning the outdoor temperature sensor
Clean the solar cell with a damp cloth and a little solvent-free soap. Do not use sprays, scouring agents, detergents, solvents or cleaning agents that contain chlorine.
Note
After you have cleaned the solar cell, there is a delay before the fault message disappears because the battery has to be recharged first.
Changing the batteries
Danger!
Risk of death caused by unsuitable batteries! If batteries are replaced with the wrong type of battery, there is a risk of explosion. Ensure that you use the correct battery type when replacing batteries. Dispose of used batteries in accordance with the instructions in this manual.
