To compensate for any pressure differential between
the supply air and extract air side, the speed of the
exhaust air fan compared to the supply air fan can be
raised or lowered. To do so the value set here is added
permanently to the control voltage of the exhaust air
fan.

Recommendation:
Set "Standby mode" for the ventilation unit. After
some time, compare the temperature values of all tem-
perature sensors against each other and/or against a
reference temperature. Set a corresponding correction
value for any deviating temperature sensors.
