OPERATION

Dual zone temperature control provides a side-to-side variation in comfort temperatures to exceed the needs of either front seat occupant.

The A/C Heater Control Module panels are serviced only as complete units and cannot be repaired. If faulty or damaged, the entire A/C Heater Control Module must be replaced.

The A/C Heater Control Module makes it possible to make adjustments coming from the driver such as:





- "Temperature" by setting the temperature thumb-wheels. (2 and 5)
- "Air quantity" by adjusting the blower switch setting. (6)
- "Air distribution" by setting the air distribution switch. (1)
- "Recirculating air" by pressing the recirculating air push-button. (4)
- Activating the residual engine heat utilization system with the ignition switched off by pressing the REST button. (4)
- Switching off the A/C by pressing the EC button (3).

The A/C Heater Control Module integrated in the push-button control module looks after all system regulation and control functions, such as:

- Automatic switch over from fresh air to recirculated air mode.
- Electrical control of the A/C compressor.
- Control of the electric fan for the engine/air conditioning system.
