PROBLEM TO BE SOLVED: To produce a remote display through a simple constitution by connecting an operational signal output means in an indoor unit with an operational signal input means in a system where an operational signal is outputted from a local remote controller and delivering information from the operational signal input means, while discriminating, to a remote operational state display. SOLUTION: A plurality of indoor units 2 to be connected with an outdoor unit 1 are connected with a local remote controller 5 delivering an operational signal for controlling the operation of each indoor unit 2. An operational state display section 12 connected with the indoor unit 2 displays an operational signal from an operational signal output means 24 on an output means. Furthermore, a remote state output relay 6 comprising an operational signal input means 25, an operational state discriminating means 26, and operational state output means 27, 28 is connected with the indoor unit 2. The remote state output relay 6 receives an operational signal from the operational signal output means 24, discriminates a plurality of operational states, e.g. operation/stoppage or normal/abnormal, therefrom and delivers the plurality of operational states to a remote operation display 8. |
