摘要： PROBLEM TO BE SOLVED: To quickly and securely judge improper wiring merely by the trial operation of an outdoor machine, by detecting the temperature change of either refrigerant path by a temperature sensor being attached to the outdoor machine, and by judging the presence and absence of the improper wiring based on the consistency/inconsistency of the refrigerant path and a signal wiring corresponding to an indoor machine. SOLUTION: When a trial operation switch 19 being provided in an outdoor machine Z is pressed, a first electric on/off valve 5A is opened, at the same time, a compressor 1 is operated, and a refrigerant passes through a four-way change-over valve 2 for circulating to an outdoor heat exchanger 3, the electric on/off valve 5A, an indoor heat exchanger 6, and an accumulator 8. At this time, the detection signal of temperature sensors 17A and 17B being provided in indoor machines A and B via signal wiring that should be connected to the first indoor machine A being connected to the outdoor machine Z is inputted into a microcomputer being provided in the outdoor machine Z. Then, the temperature of a refrigerant path 20A where the temperature sensor A is provided is rapidly reduced, thus judging whether refrigerant wiring properly corresponds to signal wiring for connection according to a detection signal at that time.
