PURPOSE:To dispense with an integrative control part as well as to facilitate measures for the replacement of an actuator, by installing a controlling device, driving the actuator on the basis of an external signal and positioning it, in the actuator driving various doors for air-conditioning use. CONSTITUTION:Motors 26M, 36M and 50M, interlocking each door via a gear mechanism, are installed in actuators 26, 36 and 50 controlling each of doors 2, 7 and 5 for air conditioning control. And, there are provided with position detectors 26A, 36A and 50A detecting a position of each motor and controlling devices 27A, 37A and 34A controlling drive circuits 25A, 35A and 60A so as to accord each position detecting signal with an external input signal Vin out of a control signal output device 82. And, a control signal input device 82 is constituted of installing a heat load detecting device inclusive of each of sensors 18, 20 and 21 for inside air, solar radiation and outside air, a manial setting device 74 consisting of an inside-outside selector door control switch and another manial setting device 78 consisting of a mode selector door control switch. |
