Setting the temperature correctly
The temperature is controlled only via the room thermostat in the living room.
👉 Important:
• The room thermostat controls the temperature
• Do not adjust or close the radiator thermostats
Radiator valves
Always keep the radiator valve in the living room set to level 2–3 (the room thermostat controls the heat). In the bedroom there is an electric radiator valve, which can be turned down if needed.
Important: The boiler requires water circulation in the heating system. Without flow, it cannot heat.
Heating in winter operation
In winter, both functions must be active:
Heating mode
Domestic hot water mode (hot water)
Only then will you have warm rooms AND hot water.
Activating winter mode – step by step
Winter mode should always be active on cold days. If, unexpectedly, it is not, please follow these steps:
At the boiler control panel:
1. Switch on the device (if it is off)
2. Use the mode/operating button to select “Heating + Hot Water”
3. Check that the heating symbol and the water tap symbol are visible at the same time
How the display should look in winter
Water tap symbol = hot water active
Radiator/heating symbol = heating active
Both symbols visible at the same time = correct.
If only the water tap symbol is visible → summer mode (hot water only) → the apartment will remain cold.
