PURPOSE:To provide a remote control system in which the complexity of the system or the limitation of an equipment or the like due to the wiring of a control signal line can be eliminated and the deterioration of an operation response can be prevented. CONSTITUTION:The transmitting media of a command signal transmitted from a remote commander RD to a concentrating controller 10 and the transmitting media of the command signal transmitted from the concentrating controller 10 are made different just like an infrared ray and a radio wave. Also, at the time of making both the transmitting media the same, carrier frequencies are set so that they can not interfere with each other. Thus, the interference of the command signal from the remote commander RD in the command signal from the concentrating controller 10 can be eliminated.
