Fans equipped with the comfort board 5/EC-FK have an independent humidity control with a stan-
dard control range of 50 - 70 % r.h. controlling between the set basic ventilation stage (DIP switches
1, 2) and the regulated ventilation stage (DIP switches 6, 7). This ensures that the exhaust air volu-
me flow is constantly adjusted to the room air humidity and room temperature, thus achieving an
optimum level of comfort. There is only as much ventilation as necessary, but also only as little as
possible, which saves energy, prevents over-humidification of the apartment and avoids structural
damage and mould.
The control is carried out in a virtually stageless and "intelligent" manner, differentiating between
permanently high relative humidity or rapid increase (e.g. due to showers).
If the relative humidity cannot be significantly reduced within a period of two hours (e.g. in summer),
the fan will be switched to basic ventilation mode.
If the relative humidity increases by more than 5% within one hour during reduced operation mode,
the reduced operation mode will be terminated. If the relative humidity falls below the lower switching
threshold and the basic ventilation level is set to OFF, the fan will be switched off.
If the fan is set to the basic ventilation level OFF, it will run once per hour for 3 minutes at the level of
15 m³/h (sniff mode). If a relative humidity above the set switching threshold, e.g. 50 % RH at 22°C,
is measured during this time, humidity control will be activated.
If the measured relative humidity is lower than the switching threshold, the fan will be switched off
again after these three minutes.
Notes:
 If voltage is applied to L2, all special functions, switch-on delay, run-on time, interval operation and
humidity control (5/EC-FK only) will be deactivated.
 Within the first two hours after connection to the mains, the fan runs at the level corresponding to
the relative humidity value currently measured .
