CONTROL DEVICE, SYSTEM AND CONTROL METHOD THEREFOR

摘要

An air-conditioning system (1) is provided with outdoor equipment (10) in which an outdoor equipment control unit (13) that is a local control unit is mounted, and a control device (3) capable of controlling the outdoor equipment (10) via a communication line (6). The outdoor equipment control unit (13) and the control device (3) are able to cooperate with each other to control the outdoor equipment (10), and the control ratio between the outdoor equipment control unit (13) and the control device (3) is dynamically changed according to the communication quality of the communication line (6). Consequently, in the system in which equipment control via the communication line is performed, it becomes possible to reduce the influence of deterioration in communication quality and a communication blackout on control.
