Operating Modes

AUTO
In this setting everything is controlled automatically based on the various A/C system inputs. In this setting, the system has the capability of any fan blower speed, any air inlet position, and any air outlet position to attain and maintain the selected temperature. Depending on the heating or cooling requirements, most of the air will enter the passenger compartment from one of the following four positions.
^ The floor heater outlet.
^ The A/C outlets.
^ The A/C and heater outlets.
^ The defrost and heater outlets.

OFF
With this setting selected, the blower motor or A/C compressor will not operate. The system will however still try to reach the temperature range selected, for example, if 21°C (70°F) is selected and it is a cold day, the car may eventually reach the 21°C (70°F) temperature range but over an extended period of time because the blower fan is not operating. If it is a hot day, it can only cool the car to near outside air temperature since in this position the blower motor and A/C compressor will not run. The OFF selection forces the air inlet valve open to outside air. The air will be discharged out the heater outlet.

Pressing the OFF button while the system is operating will cause the system to turn OFF. Pressing the button again will cause the system to return to the previous settings. The manual recirc setting is the only setting that the system will not return to after being turned OFF.
