PURPOSE:To control plural loads collectively from the outside of a room to which these loads are fitted and to shorten a control signal transmitting/receiving time when the number of loads is small by providing a load selecting means in a central control box. CONSTITUTION:The central control box 100 is provided with a selecting means 128 for selecting a load to be controlled, a remote control IC125 for charging the I/O of a control part 120 in addition to the control part 120. The selecting means 128 is provided with a pair of seesaw switches and one switch selects whether a control signal between the box and a repeater 400 is to be transmitted/received or not. The other switch selects whether a control signal between the box 100 and a receptacle box 500 is to be transmitted/received or not. Thus, the plural loads can be collectively controlled from the outside by forming the selecting means 128, the IC125, etc. in the control box 100 and the control signal transmitting/receiving time can be shortened when the number of loads is small. |
