Abstract
A movable air mix door serves to adjust the temperature of outgoing air from an air conditioner. The temperature of outgoing air depends on the position of the air mix door. A combination of a position sensor for sensing the actual position of the air mix door and a temperature sensor for sensing the temperature of incoming air into the air conditioner generates a first signal depending on the actual position of the air mix door and on the incoming air temperature. A second signal represents a target position of the air mix door. The position of the air mix door is controlled by a controller in accordance with the first and second signals. Since the combination sensor produces a signal dependent on incoming air temperature, the processing load on the controller is reduced in that the controller itself need not correct the target position in accordance with the incoming air temperature.
