Flap Setting

Flap setting







The stepper motors for flap operation execute a position run after ignition terminal 15 has been switched off. The fresh air and defroster flaps are completely opened, and all other flaps are closed.

The temperature setting flap is the only flap that remains unchanged This procedure lasts approximately 15 seconds

The IHKS performs a calibration run after every 20th time the ignition is switched off or after an interruption in memory power. The flap end positions serve as reference points.

A total of five (200 Hz) stepper motors with M-bus activation and one (500 Hz) high speed fresh air motor are used.
