PROBLEM TO BE SOLVED: To provide an air conditioning system in which confirmation of operation data of the other indoor unit from one outdoor unit is made possible. SOLUTION: In the case when there exists no operational failure in an outdoor unit 3b, an operator operates a keyboard of a maintenance device 99 and inputs a command which indicates the operation data of an outdoor unit 1a. Then, the command is transmitted to an outdoor side ECU 71 of an air conditioner 1a by way of a second bus line 93 so that the operation data of an outdoor unit 3a may be output from a nonvolatile memory. The output operation data is indicated on a display 97 of the maintenance device 99 by way of the second bus line 93 and the outdoor unit 3b. This construction makes it possible for an operator to confirm the operation data without going to the outdoor unit 1a. |
