SYSTEM DESCRIPTION
A/C auto amp. controls A/C compressor operation by ambient temperature and signal from ECM.
Low Temperature Protection Control A/C auto amp. will turn the A/C compressor ON or OFF as determined by a signal detected by ambient sensor.
When ambient temperature is greater than 4C (39F), the A/C compressor turns ON. The A/C compressor turns OFF when ambient temperature is less than 2.5C (37F).
