Humidity limitation
This function monitors the relative humidity of the air and compares it with the
set ”Humidity limit value“.
If the relative humidity exceeds the limit value, the ventilation system is
switched on at the preselected stage to remain on until the humidity has
dropped one switching differential below the limit value.
The relative humidity level (r.h.) is displayed on the central apartment unit.
In certain cases, the ventilation system is not capable of reducing the humidity
o the required level.
To prevent the ventilation system from operating continuously in such cases,
settings “Running time“ and “Pause time“ can be used to set an interval for
operation.
Interval mode is switched off again when the relative humidity drops one
switching differential below the limit value.
