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.
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
