PURPOSE:To improve the controllability of a controller having a main control unit, and a terminal control unit for locally controlling various air conditioners by providing a control unit for controlling the start or stop of the air conditioner by comparing the demand level with the command level at a terminal control unit. CONSTITUTION:A main control unit MCT is connected to a terminal equipment TE such as a keyboard, a display unit or the like to be capable of transmitting and receiving data, and is connected via a common transmission line La to sub- controllers SCT1-SCTm. To the SCT1-SCTm are respectively connected terminal control units TCT11-TCTmn which are connected with local temperature sensor T, humidity sensor H, motor control valve MV or the like. The units TCT11-TCTmn compare demand level of the predetermined importance with command level which is determined according to the power consumption state or emergency generator operating stator at the power-interrupting time, and have control unit which stops the operation of an air conditioner when the self demand level is lower than the command level. |
