With the use of a microcontroller, the Electronic Automatic Temperature Control (EATC) module analyzes input from the following major sources:

-

temperature, function and blower selection (made by the vehicle occupants)

-

in-vehicle temperature sensor

-

ambient temperature sensor

-

sunload sensor

-

vehicle speed sensor

-

engine coolant temperature sensor

Using these inputs, the microcontroller determines the correct conditions for the following outputs:

-

A/C clutch engagement

-

blower speed

-

air temperature blend door position

-

floor/panel door position

-

panel/defrost door position

-

air inlet duct door position
