Notes of automatic operation
The selected mode of operation will be automatically started, depending on the room temperature at the time of activation.
Furthermore, depending on the mode of operation, the room temperature setting should take into account the set-point temperature
(as indicated above).
Once the mode of operation has been selected, it will no longer be changed even if the room temperature changes.
In the dehumidifying mode operation, the fan turns slowly to maximise dehumidification and the fan stops periodically.
