Room drying with minimum temperature monitoring and
“Comfort ventilation”
The humidity should be lowered in a humid room. If a ventilated room is too cold, the fan is switched
off.
In order to guarantee a minimum room air quality for every day, even on days
-
with humid exterior air or
-
a drop below the set minimum room temperature
the fan is switched on with “comfort ventilation” for one or several time windows, preferable in the cool
morning hours.
The fan for room drying runs if:
-
the absolute humidity is lower outside than inside
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
