<p><P>PROBLEM TO BE SOLVED: To decrease power consumption of a wired remote controller in an air conditioner system including a plurality of indoor units connected to the wired remote controllers, by supplying power to the wired remote controller only when the power is required. <P>SOLUTION: An indoor unit includes a power supply part supplying power to the wired remote controller, a relay to supply/block power to the wired remote controller, and an indoor unit control part controlling the relay. A central control device stores a power supply control table for each indoor unit, the table storing an operation condition of the indoor unit and a power condition of the wired remote controller. The indoor unit transmits a data to the central control device for notifying the operation condition of the indoor unit upon starting or stopping the operation of the indoor unit. The central control device receives the data for notifying the operation condition, updates the term of operation condition of the corresponding indoor unit in the power control table, and transmits an instruction data for blocking power supply to the indoor unit in which the term of operation condition in the power supply control table is stopped; and the indoor unit opens the relay when receiving the instruction data. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
