Features

AIR MIX DOOR CONTROL (AUTOMATIC TEMPERATURE CONTROL)
The air mix door is automatically controlled so that in-vehicle temperature will reach, and be maintained at the operator selected "set temperature". For a given set temperature, the air mix door position will depend on:
Ambient temperature, in-vehicle temperature, amount of sunload, set temperature and A/C switch signals.

FAN SPEED CONTROL
When the fan control knob is in the Auto position, the blower speed is automatically controlled, depending on:
Ambient temperature, in-vehicle temperature, amount of sunload, set temperature, and A/C switch signals. It is also controlled by the manual operation of the fan control knob.

STARTING FAN SPEED CONTROL
When engine coolant temperature is low, the air outlet door position is detected by the microswitch and if this is set in B/L, FOOT or DEF/FOOT blower speed is controlled to prevent a large amount of cold air from being discharged into the floor area.

OUTLET DOOR CONTROL
This can be selected by operation of the mode knob.

INTAKE DOOR CONTROL
This can be selected by changing the REC switch position.

COMPRESSOR MAGNET CLUTCH CONTROL
Under normal operating conditions, when the A/C is switched ON, the compressor runs continuously, and the evaporator pressure, and therefore temperature, is controlled by the V-6 variable displacement compressor to prevent freeze up.
