PROBLEM TO BE SOLVED: To perform an automatic judgement of a communication speed between an outdoor unit and an indoor unit.SOLUTION: This invention relates to an air conditioner system 1 in which an outdoor unit 10 and a plurality of indoor units 100, 101, 102 are connected to each other in such a way that they can communicate with each other. The outdoor unit 10 can communicate with any one of a plurality of communication speeds, and each of the indoor units 100, 101, 102 includes a communication part capable of communicating with the outdoor unit with a plurality of communication speeds and a control part which waits for connecting under a first communication speed from a power activation time, and if the communication cannot be established during a first prescribed time, the control part tries to connect at a second communication speed different from the first communication speed and judges the communication speed of the outdoor unit.SELECTED DRAWING: Figure 1 |
