Electronic Climate Control

The ATC System automatically maintains the selected temperature for individual driving comfort by regulating the discharge air temperature then set in any position except OFF. The fan speed, when set to AUTO, is automatically regulated as determined by the vehicle interior temperature. The selected temperature settings are 65°F to 85°F with 65 as maximum cooling and 85 as maximum heating.

A provision is also available to manually override the auto blower function with the blower switch. Moving the switch up, away from AUTO position, provides a continuous variable blower speed range from LO to HI. the blower operates in all function positions except OFF.

Auto

Placing the ATC Function Selector lever in any position except OFF will put the system in automatic operation. 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, than 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, side to side or closed.

Blower Speed Override

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

Air Discharge Locations

OFF

Moving the function lever to OFF stops all system operations.

MAX A/C

Moving the function lever to MAX A/C provides cooling with recirculated air through the instrument panel registers. The compressor will operate.

NORM A/C

Moving the function lever to NORM A/C provides cooling with outside air through the instrument panel registers. The compressor will operate.

VENT

Moving the function lever to VENT provides outside air flow through the instrument panel registers. The air can be heated, but not cooled, in the vent position. The compressor does not operate.

FLOOR

Moving the function lever to the FLOOR position 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.

DEF/FLR

Moving the function lever to DEF/FLR allows outside air to be discharged from both the defroster outlets and the floor outlet. The compressor operates to dehumidify the air.

DEFROST

Moving the function lever to DEFROST directs outside air out the defroster outlets against the windshield. The compressor operates to dehumidify the air.
