•When the outside ambient temperature decreases, the rotation speed of the outdoor fan is regulated by
means of the outdoor heat-exchanger sensor to prevent liquid back.
•The rotation speed varies with indoor temperature conditions (Hatching area).
•The unit is protected against high pressure by means of the outside temperature sensor, and thus when
the outside ambient temperature reaches 30 ° C respectively, the fan speed is forced to high.
