IHKA Heating and Air Distribution
The Heating and Air Distribution of IHKA systems differ from the IHKS system in the following ways;
- Two servomotors controlled by the IHKA module operate the temperature blend flap and air distribution mechanism. Flap position is monitored by the IHKA using potentiometers integrated in the servomotors.
- A heater core sensor measures the temperature of the air coming off the heat exchanger. The sensor is located on the right side of the front of the heater unit.
- A rocker switch and a power transistor (final stage) controls the blower motor at eight speeds. The blower speed is controlled manually via the rocker switch or automatically in the AUTO mode.
