BMW 3: Operating principle
BMW 3 Series G20 (2018-2025) Training manual / Electrical Heating / Operating principle
If the driver adjusts a desired temperature at the IHKA controls, the IHKA calculates a corresponding nominal temperature and compares it to the actual output temperature of the electrical heating.
There is a coolant temperature sensor at the electrical heating output for this purpose. This way the IHKA control unit can decide whether the heat from the combustion engine is sufficient to heat the passenger compartment or whether the electrical heating should be switched on. If the temperature of the coolant is too low, the electric heating can heat up to a total of 6 stages. The electrical heating is always condition-based thanks to this control operation.

When the coolant temperature is low, for example after driving off, or in
all-electric driving, the electric
changeover valve is activated by the Body Domain Controller (BDC). The

Climate Control
As in previous BMW hybrid vehicles, an electrically powered air conditioning
compressor is used in
the G20 PHEV. Because the A/C compressor has an electric motor, it is possible
to operate the air
conditioning independently of the combustion engine. Thus the customer can enjoy
the cooling ef
