摘要： PROBLEM TO BE SOLVED: To realize remote control address setting by determining an address setting order among a plurality of indoor units, driving an informing means of an indoor unit determined based on the address setting order and then setting the driven indoor unit with an address outputted from a remote operating means through the informing means. SOLUTION: Upon finishing installation and wiring of an outdoor unit and an indoor unit, system power is turned on. When an operator depresses an operating button on a remote controller R previously assigned to 'address setting' after the address of an indoor unit is set, an 'address setting' data is delivered on a signal line S2 from the remote controller R. The CPU 11 in each indoor unit reads out and interprets the data. Since the number of data receiving times is '1', the CPU 11 checks the 'address setting order 'N'' data stored in an RAM 13 and delivers a fan motor drive command to a control interface 17 when the number of receiving times '1' matches the address setting order.
