Control system: Notes
WARNING: This page is about a different car, the 2004 Land Rover Discovery, 2003 Land Rover Discovery, and 2002 Land Rover Discovery. However, it is still accessible from the selected car via links, so may be relevant.
The control system operates the refrigerant system and the control flaps in the heater assembly to control the temperature and distribution of air in the vehicle interior. It also outputs signals to the fresh/recirculated air servo motor and the blower to control the volume and source of inlet air. The control system consists of:
- An Air Temperature Control (ATC) ECU.
- A dual pressure switch.
- An evaporator temperature sensor.
- An in-car temperature sensor.
- A sunlight sensor.
- A heater coolant temperature sensor.
- An ambient temperature sensor.
