ABSTRACT:
An electronic circuit for controlling the heating or air conditioning apparatus in an automobile permits the capability of heating the vehicle without the heat surges which can occur after short periods of ignition turn off and permitting manual on-off control of the heating system even if the thermostat fails. A second circuit for controlling the device activating the valve controls the flow of heating or cooling medium independently of the ignition switch and contains a timer to keep the valve closed for a predetermined time after ignition switch-off. Two limit switches are also present for permitting the valve to be set at an open or closed position independently of both the ignition switch and the timer.
