Abstract

PURPOSE:To reduce the cost and simplify signal line-wiring by electrically connecting a remote control panel, which is capable of individual ON-OFF control of the operation of a plurality of indoor units, to a multicontroller through an interface. CONSTITUTION:A remote control panel 17 is electrically connected to a multicontroller 14 through an interface-PC board 16 so that it suffices to use only one unit of interface-PC board 16 for the system and only one signal line for the connection between the interface-PC board 16 and the multicontroller 14. Thus a reduction in cost and simplification of the wiring work for the signal line can be achieved. The multicontroller 14 is designed to selectively transmit ON-OFF signals, which it receives from the remote control panel 17, to indoor units 11A-11D; the indoor units 11A-11D first transmit the ON-OFF signals, transmitted selectively from the multicontroller 14, to respective remote controllers 12A-12D and received the signals back in acting according to the ON-OFF signals.
