Room drying and "comfort ventilation", both with
minimum temperature monitoring
The humidity should be lowered in a humid room. In order to ensure room air quality to a large extent,
the fan is switched on for one or several time windows, preferably in the cool morning hours, even on
days with humid exterior air. If the set minimum room temperature is fallen short of, this “Comfort ven-
tilation” will also be blocked.
The fan for room drying runs if:
- the absolute exterior humidity is lower than the interior one and
- the room temperature is high enough (protection against too much cooling down in the winter)
and the optional interval switch ("Timer") is active.
The fan for “comfort ventilation” runs
- daily according to time window if the room temperature is high enough.
