The present invention discloses a central control system and an operation method of the central control system which restricts a control signal received by indoor units and operates the indoor units according to setting of a schedule when a central control unit sets the schedule for controlling the operations of the indoor units. According to the present invention, the indoor units can be individually controlled by restricting external signals input to the indoor units and controlling the indoor units so that the indoor unit can be operated by the signals input from the central control unit. Further, since the indoor units can be individually controlled, unnecessary waste of power consumption can be prevented, the effectiveness of the central control of the central control unit can increase, and the function of the schedule can be reinforced. |
