The output of the indoor unit is too low. Temperature is set too high or too low.
Air filter is soiled and must be cleaned.
Unfavourable ambient conditions for the indoor unit, e.g. the ventilation openings of the devices are
obstructed, doors/windows in the room are open or the room contains powerful heat sources.

indoor air and air-conditioned air.
White mist is emerging from the indoor unit and

If heating mode is activated directly after automatic defrosting, this can generate white mist due to
the higher level of humidity.
