System Airflow Description - Dual Automatic Temperature Control (DATC)/Electronic Automatic Temperature Control (EATC): Auto
WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
When AUTO is selected:
- the temperature control setting is manually set to the desired setting.
- the air inlet door actuator is automatically controlled by the HVAC module - EATC or HVAC module - DATC, based on the temperature setting.
- the mode door actuators are automatically controlled by the HVAC module - EATC or HVAC module - DATC based on the temperature setting.
- the A/C compressor is automatically controlled by the HVAC module - EATC or HVAC module - DATC based on the temperature setting. The A/C compressor will not operate if the outside temperature is below approximately 6°C (43°F).
- the A/C request is controlled by the HVAC module - EATC or HVAC module - DATC based on the temperature settings. The A/C compressor will not operate if the outside air temperature is below 6°C (43°F). The A/C indicator automatically turns ON when the outside air temperature rises above 14°C (58°F) and automatically turns OFF when the outside air temperature falls below 11°C (51°F).
- the A/C request button and the RECIRC request button can be manually selected. When manually selected the A/C indicator will not change state with changing outside air temperature.
- the blower motor is ON. The blower motor speed is automatically controlled by the HVAC module - EATC or HVAC module - DATC based on the temperature setting, but can be manually overridden.
