When the evaporator is in heating mode and the external temperature is below 6°C, a protection system will come into action that will turn off the internal ventilation for a period of 9 minutes and 40 seconds, returning to heat the room after this period.
When the evaporator is in heating mode and the outside temperature is around 10°C, a protection system will come into operation that will keep running at low fan speed. In this condition the medium and high speeds will not be enabled for use.
