Abstract

PURPOSE:To make various setting through simple operations and to flexibly cope with changes in system, by performing two-position control of facility apparatuses through a terminal in such a way that information and measured values indicating the operating conditions of the apparatuses are fetched through the terminal and compared with set values and controlling conditions, and then, the necessity of starting and stopping the apparatuses is discriminated in accordance with the compared results. CONSTITUTION:Facility apparatuses 8, sensor 1, and main facility apparatus sensor 9 are provided under the control of a terminal. At a centralized control room an operating value setting section 5 sets the start/stop operating values of the facility apparatuses 8 which control the temperature, intensity of illumination, etc., in accordance with measured values and a schedule setting section 6 sets a time zone, timing (season), etc., for making two-position control to the aparatuses 8. A facility apparatus designating section 7 designates those to be controlled and a main facility apparatus (related facility apparatus) out of the facility apparatuses 8. A comparator section 2 compares a measured value and operating value obtained through the sensor 1 with each other and an operation discriminating section 3 discriminates whether or not the start/stop control of the facility apparatuses can be performed from the set content of the schedule setting section 6, the presence/absence of occurrence of fire and power failure, and the operating condition of the main facility apparatus, and performs the start/stop control of a designated facility apparatus.
