PROBLEM TO BE SOLVED: To rapidly determine a parent unit and to improve comfort, by outputting a parent declaration signal for each output of one bit signal of a serial number at each parent child determination processing. SOLUTION: A parent determination means 65 determines a parent unit when a parent declaration means 62 completes outputting a parent declaration signal OPCA4 and when a bit signal means 61 completes outputting the signal of total bits (for 3 bytes) of a serial number. A modification means 66 compares the serial numbers of the parent declaration signal OPCA4 when the parent determination means 65 receives the parent declaration signal OPCA4 from another outdoor control unit 2A while a parent unit is being determined, cancels the parent determination of each parent determination means 65 when a priority is lower, for example when the serial number is small based on the predetermined order of priority of the serial number and determines it to a child unit, thus reducing the processing time for determining parent/child. |
