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