PURPOSE:To reduce the labor required for special control action by storing a special time schedule in an area inside a memory, and causing the special time schedule to take priority over a normal one during control action, and erasing the special time schedule after an effective limit, and then recovering normal control. CONSTITUTION:At the control portion 21 of each illumination main control device a normal time schedule stored in a memory 241 is put into action to control a lamp connected to a terminal 3. To perform special control action, a special time schedule is input from the input portion 13 of a center device 1 to a control portion 12 and a load command to an illumination main control device 2-1 is sent and transmitted and received between communication control portions 11, 22 and the special time schedule received is stored in an area 242 inside a memory 24. Priority control action is performed according to the special schedule and when the effective limit of the special schedule is exceeded the special schedule is erased and the action of the normal time schedule is recovered. The labor required for an operator at the special control action can thus be reduced. |
