The purpose of the present invention is to provide a novel air conditioner that can recognize the communication speed of an input signal even when no manual selector switch is provided. A control device 12 in an indoor unit 11 is provided with a plurality of communication means 14a-14c having different communication speeds, a communication speed recognition means 18 that recognizes, from the communication speed of the control information signal, to which of the communication means that a communication line 15 from the indoor unit 10 is connected, and a communication means determination means 18 to determine the communication means to perform subsequent communications on the basis of the recognized communication speed. Thus, the communication speed of an input signal can be recognized even when no manual selector switch is provided. As a result, at least one of problems of complicated construction work, the likelihood of an error in setting the selector switch, and high product costs, is resolved. |
