Compressor Control
A/C Compressor Relay ON Conditions
-
The air inlet sensor which senses the temperature of the air sent to the evaporator, and the air thermo sensor, which senses the temperature of the
air flowing out of the evaporator, are deactivated with temperature 3.2°C (38°F) or below.
Here, the engine coolant temperature sensor senses the temperature of engine coolant, and it is turned off at 115°C (239°F) or higher temperatures.
-
The triple pressure switch (or dual pressure switch) turns OFF when the refrigerant pressure becomes excessively high or low, thus protecting the
compressor circuit.
-
When these three sensors are all activated, the triple pressure switch (or dual pressure switch) is ON, and the ignition switch, blower switch, and
air conditioning switch are ON, the A/C compressor relay is energized.
