Resolution:
There are three possible causes:
- The “Fan mode” is set to “Low” instead of “Auto”.
- Auto selection will activate fan on demand.
- The “Auto Fan func.” is set to “AS”.
- Change the setting to “AS / AD”.
- AS: In Occupied, Standby, and Override modes, the Fan stays ON at low speed even if there is no demand for Heating or Cooling. In Unoccupied mode, the Fan turns Off when there is no demand for Heating or Cooling.
- AS/AD: In any Occupancy mode, the Fan turns Off all speeds when there is no demand for Heating or Cooling.
- The Dehumidification is activated.
- If dehumidification is not required, set the “Deh. lockout” parameter to “Disable”.
