ABSTRACT:
A control device which includes a heater core for heating the air, temperature sensors for detecting the temperature of the air, air mix dampers for adjusting the volume of the air through passing the heater core, a water valve for adjusting the volume of the water which is used for cooling an automobile engine, an actuator for operating the air mix damper and the water valve and a control unit is disclosed. The control unit compares a desired position, and predetermined positions of an opening angle of the actuator with each other. The temperature of the air which is blown out from an automotive air conditioning system can thereby be controlled in accordance with the compared results.
