Air Distribution (IH(K)S Integrated Heating/Air Conditioning Control E85)
Air Distribution
The air distribution is by means of a stepper motor. The stepper motor for adjusting the total of 3 air distribution flaps is mounted directly behind the cam disk.
The control panel/control module drives the stepper motor (corresponding to the required position) when the rotary control for air distribution is operated. The cam disk moves the air distribution flaps by means of the central kinematics. A time of approx. 18 seconds is required for an adjustment range of 180 degrees.
Two cams of different width are mounted on the cam disk for the purpose of determining the actual position of cam disk 1.
This cam switches a microswitch 2. This switching serves as the feedback for the position of the stepper motor and cam disk.
