Electronic Climate Control

DESCRIPTION

The EATC System automatically maintains a selected temperature for individual driving comfort by regulating the discharge air temperature when set in any position except "OFF". The fan speed, when set to "AUTOMATIC", is automatically regulated as determined by the vehicle interior temperature. The selected temperature settings are 60°F (maximum cooling) to 90°F (maximum heating).

A provision is also available to manually override the auto blower function with the blower potentiometer. Moving the Potentiometer provides a continuous variable blower speed range from "LO" to "HI". The blower operates in all function positions except "OFF".

Automatic Mode

Pushing any button, except "OFF", will put the system in automatic operation. The "WARM" and "COOL" buttons allow the user to change the set temperature. The A/C compressor is automatically engaged in all function positions except "OFF", "VENT" and "FLOOR". The discharge air temperature and blower speed are automatically set to quickly bring the vehicle interior to the set temperature. Setting the temperature higher or lower than the comfort setting will not heat or cool the vehicle faster than when set at the desired temperature. During cold weather, the fan will not operate in the "FLOOR" position until the engine reaches a predetermined temperature.

The air conditioner and heater are controlled automatically to achieve the selected in-car air temperature. To maintain comfort, the instrument panel registers can be tilted up or down and side to side. The registers can also be closed.

Blower Speed Override

Moving the selector lever to "LO" fixes the blower speed in low. Moving the blower temperature lever between "LO" and "HI" will allow a speed proportional to the position of the potentiometer and cancel the auto blower control. The system will continue to maintain the set temperature during blower override operation.

Air Discharge Locations

OFF - Pushing "OFF" button stops all system operations.

MAX A/C - Pushing "MAX A/C" button provides cooling with recirculated air through the instrument panel outlets. The compressor will operate.

VENT - Pushing "VENT" button provides outside air flow through the instrument panel outlets. The air can be heated but not cooled in the vent position. The compressor does not operate.

PNL-FLR - Pushing the "PNL-FLR" button allows outside air to be discharged from both the instrument panel outlets and the floor outlets. The compressor operates to dehumidify the air.

FLOOR - Pushing "FLOOR" button allows outside air to be discharged through the floor outlets. The air can be heated but not cooled in this position. The compressor does not operate.

FLR-DEF - Pushing the "FLR-DEF" button directs outside air out the defroster outlets and the instrument panel outlets. The compressor operates to dehumidify the air.

DEFROST - Pushing "DEFROST" button directs outside air out the defroster outlets against the windshield. The compressor operates to dehumidify the air.
