Heating and Air Conditioning: Description and Operation

Fig. 1 Control Assembly:

The Electronic Climate Control (ECC) system automatically maintains a selected temperature by regulating the temperature of the A/C discharge air and fan speed. The temperature, directions, and rate of airflow are determined by lever and push-button switch settings in the control assembly, Fig. 1. A self test feature is incorporated into the control assembly which provides error codes to determine any damaged components. Manual adjustment of air outlets and fan speed is also provided.
