The fan operates as part of the AUTO mode or the ON mode.

Under the AUTO mode, the fan runs in any of the following situations:

  • Heating is active.
  • Cooling is active.
  • The humidification function is active.
  • The dehumidification function is active.
  • Free-cooling is enabled.
  • Ventilation is activated to improve the room air quality.

When the fan is switched off and ventilation is in AUTO mode, you can switch the fan from AUTO to ON as needed. The fan is switched on by default after three minutes.

User can adjust “Fan min. ON time” via “Advanced Settings” > “Optimization” to influence the fan’s minimum runtime.

Under the ON mode, the fan works regardless of whether any of the above functions is on.
