Electronic Automatic Temperature Control (EATC) and Dual Automatic Temperature Control (DATC) System
WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The electronic automatic temperature control (EATC) and dual automatic temperature control (DATC) system operation is determined by the settings on the DATC/EATC module. The DATC/EATC system automatically maintains a selected temperature for vehicle interior comfort. The DATC/EATC system is composed of the DATC/EATC module, blower motor speed control, mode door actuator, air inlet door actuator, temperature blend door actuator, in-vehicle temperature sensor and solar radiation sensor to control the various functions.
When the DATC/EATC module is set to AUTO:
- The air distribution direction, blower motor speed and A/C compressor operation are automatically controlled based on the temperature(s) selected.
The DATC/EATC module manual override settings:
- Allow the air distribution direction to be manually selected.
- Allow the blower motor speed to be manually selected.
- Allow RECIRCULATION mode to be manually selected in all modes except DEFROST. The A/C request can be cancelled by pressing the A/C request switch, turning the indicator OFF.
- Allow A/C compressor operation to be manually selected except in DEFROST.
The auxiliary climate controls:
- Select the auxiliary blower motor speed.
- Select the auxiliary airflow mode/temperature.
The DATC/EATC module also includes:
- A rear window DEFROST button, refer to GLASS, FRAMES AND MECHANISMS .
- Heated/cooled seat controls, refer to SEATING .
