決定された空気調和機の制御方法。(2) When operating the air conditioners by supplying power to multiple air conditioners and other devices via an overcurrent protection device that turns off electricity when an overcurrent flows, the air conditioners and other devices measures the current of the power supply line to which it is connected, and when it is detected that this current value exceeds the first set current value, the air conditioners are connected in order of priority. When it is detected that the current value exceeds the second set current value, the air conditioners are stopped in order from the lowest operating priority, and the current value exceeds the third set current value. When it is detected that the current value has fallen below the fourth setting current value, all air conditioners are stopped, and when it is detected that the current value has fallen below the fourth set current value, the air conditioners that are in suppressed operation or stopped are set to high priority operation. Each instruction signal is transmitted to the air conditioners in order to return to normal operation, and the operation priority is set such that the air conditioner that started operation the latest is given top priority, or the elapsed time from the start of operation is determined. Air conditioners operated within a predetermined period of time that were operated later are given priority, or air conditioners that have the same operating priority set and that are operated later are given priority. The control method for the air conditioner is determined to follow the operating priority set in advance except for the following.
