Compressor Control System

1. When the A/C switch and fan switch are turned ON, the A/C relay activates. The compressor is turned on, and then the main and sub fans also operate. Blower relay operates to direct the air flowrate determined by FAN switch position.
2. The thermo amplifier activates to stop the compressor clutch, and main and sub fans.
3. When the "High-Low" pressure switch operates, the compressor clutch stops and the main and sub fans stop.
