Room drying with minimum temperature monitoring
The humidity should be lowered in a humid room. If a ventilated room is too cold, the fan is switched
off.
The fan 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.
Recommended settings for UVR61-3
