Sensors and Actuators

Sensors and Actuators

The following lines are connected to the a/c control panel (control unit) to supply the necessary inputs for individual functions:
- Terminal 15
- Terminal 30
- Terminal 31
- Signal ground
- Reference voltage 5.0 V
- CAN interface

The remainder of the air conditioning system breaks down into actuators and sensors. The software of the control panel (control unit) monitors all of the system's measurement and control operations.

The sensor system comprises the following components:
- Interior temperature sensor (integrated into the control panel)
- Temperature sensor for fresh air intake (in the fresh air intake port)
- Temperature sensor for footwell air outlet
- Sun sensor
- Check back signals from the drive motors (see section "Air and flap controls")
- Check back signal - actual fan voltage
- Check back signals - a/c compressor status (compressor voltage)
- Pressure sensor
