PROBLEM TO BE SOLVED: To obtain centralized control function suitable for an air-conditioning instrument for high air-tight, high heat insulation living house by a method wherein a refrigerating circuit and a control circuit are constituted while an operation stopping commanding signal from an indoor unit is received by the control circuit of an outdoor unit and the selection of whether the mode of stopping all of indoor units is transmitted or not is effected. SOLUTION: Indoor units 2A-2D are connected to an outdoor unit 1 while a refrigerating circuit is constituted on the indoor units 2A-2D. A remote control unit of a remote controller transmits a temperature, air volume, air direction and an operation mode, which are set on the remote controller upon operation, to the indoor units 2A-2D as operation commanding signals. When a stop commanding signal is received from either one of the indoor units 2A-2D and a dip switch on the control circuit of the outdoor unit 1, which sets the simultaneous operation mode of all of the indoor units, is being put ON, a simultaneous operation stopping signal is transmitted to all remaining indoor units. According to this constitution, centralized control can be effected by the operation of one set of remote controller. |
