Description

1.	The ambient 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.

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

If the ambient temperature is below 2.0°C (35.6°F), the A/C compressor will be stopped.

The compressor will be operated by manual operating.
