Control Components - Electronic Automatic Temperature Control (EATC): Notes
WARNING: This page is about a different car, the 2005 Mercury Sable and 2005 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
With the use of a micro-controller, the remote climate control module (18C612) analyzes input from the following major sources:
- Integrated control panel (temperature, air distribution and blower selection)
- in-vehicle temperature
- ambient temperature
- sunload
- vehicle speed
- engine coolant temperature
Using these inputs, the micro-controller determines the correct conditions for the following outputs:
- A/C compressor (19703) operation
- blower speed
- air temperature blend door position
- airflow mode door position
- defroster door position
- air inlet door position
