Ambient Temperature Sensor / Switch HVAC: Description and Operation

1. The air temperature sensor is located at the front of the condenser and detects ambient air temperature. It is a negative type thermistor; resistance will increase with lower temperature, and decrease with higher temperatures.

2. The sensor output will be used for discharge temperature sensor, sensor fail-safe, temperature regulation door control, blower motor level control, mix mode control and in-car humidity control.

NOTE: If the ambient temperature is below 3.5 °C (38.3 °F), the A/C compressor will be stopped. The compressor will be operated by manual operating.
