Setting the heating season
Important:
Heating settings affect the defrosting function of the unit. If you select that post- and additional heating are not in use, fan stop must be selected as the defrosting method.

Set the heating season by moving the slider to the preferred value. The adjustment range is 0°C…+19°C. The factory setting is +12°C.

The outdoor temperature triggers the seasonal heating mode. When the outdoor temperature is lower than the set value, post-heating is used where needed to heat the supply air. The bypass is always 100% in heat recovery.
When the outdoor temperature is lower than the reference value:
- seasonal heating is disabled
- supply air heater is disabled
- Bypass and partial bypass are enabled.
