Anti-frost protection:
The ventilation unit is fitted with a frost protection, as any condensation
in the heat exchanger could freeze in the case of low, outside
temperatures.
The outside air flow is reduced so that there is no further risk of freezing.
The frost protection is fixed at the factory setting.
Adjusting the volumetric flow on the exhaust air side
There is a potentiometer (P2) on the ventilation unit's switchable power unit for
adjusting the exhaust air volumetric flow to the supply air volume flow. This
setting may only be made by MAICO Customer service.
■
Anticlockwise = Reducing the exhaust air volumetric flow
■
Clockwise = Increasing the exhaust air volumetric flow
