Beschreibung
Zusammenfassung:	A system and method are provided for controlling a heating and air-conditioning system, having a refrigerant circuit that can be operated as a heat pump system having an ambient heat exchanger in which, during cooling operation, heat is given up by the refrigerant to the air flowing through the ambient heat exchanger and, in heating operation, heat is picked up by the refrigerant from the air flowing through the ambient heat exchanger. A quantity of air flowing through the ambient heat exchanger is influenced by way of an electric fan. The electric fan is activated during cooling operation as a function of the refrigerant high-pressure and during heating operation as a function of a parameter independent of the refrigerant high pressure.
