ABSTRACT:
A control circuit for a vehicle-mounted air conditioner having plural dampers therein comprises a manual command entry unit for entering command signals to a computer unit. The computer unit includes a first computer constantly powered by a vehicle-mounted storage battery to receive a temperature resetting command signal from the entry unit and a second computer which is powered from the battery through an engine ignition key switch to receive control data from the first computer to control the air conditioner. A plurality of operating parameter sensors also supplies sensed operating parameters to the second computer to permit it to control one or more of the dampers to direct conditioned air to the vehicle compartment. A display unit receives data from the computer unit to provide visual display of the reference temperature and the operating conditions of the air conditioner.
