GENERAL
The air conditioning system has the following controls:

Control
Outline
Variable Capacity Compressor Control
Through the calculation of the target evaporator temperature based on various sensor signals, the air conditioning amplifier assembly optimally controls the discharge capacity by regulating the opening extent of the cooler compressor solenoid control valve.
PTC Heater Control*
When the ignition switch is turned ON, and the blower motor is turned on, the air conditioning amplifier turns on the PTC heater assembly if the conditions listed below are met.
  1. Engine coolant temperature is below specified temperature.
  2. Ambient temperature is below specified temperature.
  3. Tentative air mix damper opening angle is above the specified value (MAX HOT).
  1. *: w/ PTC heater
