PURPOSE:To eliminate the OFF operation of overcurrent protectors by constituting an apparatus in such a manner that a secondary comparison means comparing the output of a secondary current set means is installed and a plurality of air conditioners are controlled by commonly using an individual remote controller for operating each air conditioner and a terminal device for operating each air conditioner. CONSTITUTION:At an input operation part 19 setting the operating room temp. of air conditioners, a plurality of keyswitches corresponding to the air conditioners are placed respectively and the ON, OFF conditions of the keyswitches are read through a CPU 1 and the command of the operating room temp. is transmitted to each terminal device (a) for operating the air conditioner through a command signal transmission part 2. Respective outputs of comparators b1, b2 are read through the CPU 1 and when current flowing through the wiring of dwelling houses and detected by a CT circuit is larger than the output of a secondary current set means 14, in every system where a plurality of air conditioners are connected to the wiring of dwelling houses a collective stop signal is transmitted to each device (a) through the part 2.
