PROBLEM TO BE SOLVED: To perform a new installation of a cut-off control device 2 in a building having a plurality of already-installed air conditioners 9, 10, 11 in which if a time Wj where all load currents Is exceed a rated current I1 of a switch 15 is less than a continuous specified time Wj0, the switch 15 is not cut off, a cutoff notice signal just before the switch 15 is cut off is transmitted from the cut-off control device 2 to each of outdoor units 26 by a simple transmittance route to stop a compressor 29 and a frequent starting or stopping operation of the compressor 29 is prevented.SOLUTION: An advance notice signal is transmitted from a wireless transmitter 21 near a cut-off control device 2 and received by one receiver 48 near each of outdoor units 26. The receiver 48 stops a compressor 29 of the outdoor unit 26 only for a reduced limit time WF (3 minutes, for example) and thereafter it drives the compressor during at least a predetermined normal specific time WN (6 minutes, for example).SELECTED DRAWING: Figure 1 |
