Compressor Clutch: Description and Operation

Auto amplifier controls compressor operation by ambient temperature, intake temperature, and signal from ECM.




Low temperature protection control
Auto amplifier will turn the compressor "ON" or "OFF" as determined by a signal detected by ambient sensor and intake sensor.
When ambient temperatures are greater than 1.7°C (35°F), the compressor turns "ON". The compressor turns "OFF" when ambient temperatures are less than -1°C (30°F).
When ambient temperature is lower than 13°C (55°F) and the temperature detected by intake sensor is less than 7°C (45°F), the compressor turns OFF after receiving a signal from ECM.
