Functional description
At the blower output stage, the control unit of the integrated automatic heating/air-conditioning system (IHKA control unit) specifies the nominal voltage for the blower motor. The nominal voltage is output by the IHKA control unit as a signal on the LIN bus. The activation of the blower motor via the blower output stage takes place depending on this control signal.
