ABSTRACT:
In the air conditioning apparatus, the air conditioning amplifier unit e is connected to the plurality of door actuators through a single communication line and a single power source line, and also there is provided a fan motor maximum voltage limit control means which not only can create a communication signal to be transmitted through the single communication line in the form of two-way signals including a transmission signal containing door target stop position data to be transmitted to the door actuators, and a response signal to be sent back from the door actuators, but also, when the door target stop position data transmitted last time is different from the door target stop position data transmitted this time, can exert a maximum voltage limit on a fan motor, and, when the signal to be sent back from the door actuators, to the air conditioning amplifier unit is a control end signal which indicates that the door position reaches the target position and the door control is ended, can remove the exertion of the maximum voltage limit.
