b. Long stop time
The humidity has not fallen below the activation threshold by the end of the overrun limit. The fan will then be deactiva-
ted, the long stop time of six hours will run.
Background: Since the humidity value has not fallen below the activation threshold, it can be assumed that further
ventilation makes no sense. A long stop time will be activated. Any humidity measurements are ignored during the stop
time.
→ The required ventilation stages can still be operated. The stop time will be cancelled when actuated.
A balance between minimised energy consumption and optimal humidity reduction is achieved with these humidity cur-
ve control functions. Damp surfaces due to condensation and the associated risk of mould formation and unpleasant
odours are largely avoided.
7. Checking the humidity function
If the humidity required for the initial commissioning is not available, then the fan unit can be checked as follows:
If a damp cloth is held below the facade, the humidity sensor will detect a rapid humidity increase and it will activate the
fan after approx. 20-40 seconds.
8. Functional disturbances
In order to enable a correct humidity measurement, the fan or the fan temperature must be adjusted to the temperature
of the installation site. A warm fan in a cold environment or a cold fan in a warm environment will lead to a shift in the
humidity measurement value. The electronic control unit has been designed and extensively tested according to the
current regulations (DIN, EMV). Should functional disturbances still occur, proceed as follows:
– Check that electrical connection is correct.
– Disconnect the unit from the power supply by switching off the fuse for at least 30 sec. Then switch the fuse on
again.
– It must be ensured that sufficient supply air can flow into the room to be ventilated. If the functional disturbance can-
not be resolved with these measures, please contact the Helios customer service team.

There must be no repair attempts in the terminal box!
Material damage due to touching electronic parts!
The unit electronics can be destroyed by a static discharge.
►Only carry out functional test with mounted facade.
