PROBLEM TO BE SOLVED: To operate each indoor unit individually or all indoor units simultaneously by setting a remote controller selectively with a data for identifying each of a plurality of indoor units according to a specified order or a data for identifying all indoor units simultaneously and transmitting a set data along with the identification data. SOLUTION: A selection switch 22 selectively sets the identification number of indoor units 21-1,..., 21-6 subjected to alteration of setting individually or all identification numbers simultaneously and a remote controller 20 transmits a setting data for the indoor temperature of the indoor units 21-1,..., 21-6 or the fan speed, by radio, along with the identification number. Since only a set of selection switches 22 of ascending order 22a and descending order 22b are required, the remote controller 20 can be reduced in size even if the number of indoor units 21-1,..., 21-6 to be installed is increased. Furthermore, when the indoor unit 21-1,..., 21-6 is set with a data, the identification number of indoor unit 21-1,... 21-6 subjected to alteration of setting can be selected easily by means of the selection switch 22 without requiring any troublesome operation. |
