Abstract
A control device is used in a car-mounted air-conditioner of the air mixing type, in which a portion of the cold air, obtained by passing air through an evaporator, is heated by a heater via an air mixing damper. The control device includes a pulse generator, which is supplied with the outputs of a temperature setting device and of a room temperature sensor both of which are provided in a car in which the air-conditioner is mounted. The control device provides an amplified multi-phase pulse signal, based on deviations of the outputs, to an intermittent driving device responsive for rotating the air mixing damper.
