Climate Control

Operation
By switching on the FHK system, the climate control is activated via the FHK relay box and the rear shut-oft valve is switched on. The heating valve is switched on by turning one of the two temperature control wheels from the end position "COLD". By way of the flap program, the temperature is mixed between the heating element installed in the FHK and the evaporator.
