DESCRIPTION & OPERATION
Automatic temperature control system is a cycling clutch type with an expansion valve. (Scheme 3)
Sensors respond to various conditions in A/C system and provide signals for A/C-heater control panel and A/C amplifier. Based on signals from sensors, A/C-heater control panel and A/C amplifier control operation of compressor clutch and air control door servomotors.
- Ambient temperature sensor monitors outside air temperature.
- In-vehicle temperature sensor monitors passenger compartment air temperature.
- Engine coolant temperature sensor monitors engine coolant temperature.
- Solar sensor monitors sunlight load.
- Evaporator temperature sensor monitors evaporator temperature.
