2.3 Reading and setting the comfort 

temperature 

The unit will strive for the most comfortable 

supply air temperature based on the set comfort 

temperature.

 It is best to set the comfort temperature to the 

same temperature as the room thermostat (of the 

central heating system).

The comfort temperature can be set between 

12°C and 28°C. How to read or set the comfort 

temperature on the present operating device can be 

found in the document of the operating device.

2.4 Switching the supply fan on and off 

When required, the supply fan of the unit can be 

turned off manually. This may be desired to keep 

out unpleasant odours from outside. Bear in mind 

that switching off the supply or exhaust fan will 

temporarily immobilise your dwelling’s balanced 

ventilation system, so do not forget to turn the 

supply fan on again. How to switch the supply fan on 

or off on the present operating device can be found 

in the document of the operating device. 

When can the supply fan not be turned off on the 

display?

To prevent air being sucked back from the chimney 

of a fireplace the unit is fitted with an open fire 

programme. When needed the installer or service 

engineer can turn this programme on. If the open fire 

programme is turned on the supply fan cannot be 

turned on or off manually.

When can the supply fan not be turned on?

The supply fan cannot only be operated manually 

but can also be controlled automatically by the unit 

itself. This occurs in the winter to protect the unit 

from freezing. If the supply air is too cold for the 

unit, the unit will automatically switch the supply fan 

off. In this case the supply fan cannot be turned on 

manually.
