Dual Automatic Temperature Control
WARNING: This page is about a different car, the 2004 Lincoln Aviator. However, it is still accessible from the selected car via links, so may be relevant.
The dual automatic temperature control (DATC) module analyzes input from the following major sources:
- Temperature, function and blower selection (made by the vehicle occupants)
- In-vehicle temperature
- Ambient temperature
- Sunload
- Vehicle speed
- Engine coolant temperature
Using these inputs, the DATC module determines the correct conditions for the following outputs:
- A/C compressor operation
- Blower speed
- LH side temperature blend door position
- RH side temperature blend door position
- Panel airflow door position
- Floor airflow door position
- Defrost airflow door position
- Air inlet door position
