Supply air temperature during defrosting

The supply air temperature setting determines the supply air temperature during bypass defrosting. The temperature range is 12–20°C (factory setting: 15°C). In severe frost, if the heating resistor’s capacity is not enough, the ventilation unit does not allow the supply air temperature to drop below 12°C.

  1. Select Settings:
  2. Go to Expert settings and select Defrost settings:
  3. Set the target supply air temperature during defrosting. The temperature range is +12°C – +20°C. The factory setting is 15°C.
