Appliance description
Information
With an air/water heat pump, frost may form on
the evaporator fins of the outdoor unit, depending
on the air temperature (below approx. +7°C), air
humidity and the operating point. The evaporator
fins are automatically de-iced again in cyclical de -
frosting mode of the heat pump.
Fan:
The outdoor air is drawn through the evaporator by a quiet
fan.

The OCHSNER heat pump controller includes devices
capable of controlling heat pump heating systems with a
cooling function as well as DHW heating. In its standard
