The (EATC) system provides automatic regulation of the vehicle’s interior temperature. The system is based on the operator selected “set temperature”, regardless of the outside temperature changes.

There are five sensors as the input signal to the microcomputer-based EATC unit: 1. Engine coolant ambient ; 2. Ambient ; 3. Potentio balance resistor; 4. In-vehicle ; 5. Sunload sensor.

The following components are automatically controlled so that in-vehicle temperature will reach and maintain the set temperature: 1. Compressor; 2. Air intake door; 3. Air mix door; 4. Mode doors; 5. Blower speed.
