When the service engineer completes all the above operations, the service engineer returns to the air conditioning controller 3 and receives the IP address, installation position data, and refrigerant system data associated with each other from the engineering computer 7 using the wireless LAN. Forward to 3. Then, the air conditioning controller 3 stores the IP address, installation position data, and refrigerant system data associated with each other in the second EEPROM 35.

[Characteristics of engineering computer]
(1)
In the engineering computer 7 according to the present embodiment, the fifth computing unit 71B determines whether the contents of the actual information database 74g and the design information database 74f match in accordance with an instruction from the fifth control unit 71A. . Then, when the fifth calculation unit 71B determines that “the contents of the actual information database 74g and the design information database 74f are the same”, the fifth display unit 46 follows the instruction of the fifth control unit 71A as shown in FIG. The information input dialog shown in is displayed. On the other hand, if the fifth computing unit 71B determines that “the contents of the actual information database 74g and the design information database 74f do not match”, the fifth display unit 46 warns in accordance with an instruction from the fifth control unit 71A. Displays a dialog. For this reason, a service engineer or the like can easily confirm whether the indoor unit 20 is correctly installed without imposing a heavy burden.

(2)
In the engineering computer 7 according to the present embodiment, a service engineer or the like inputs information by operating the fifth input unit 79 in the customer name, address, and contact fields in the information input dialog, and then transmits the information. When the button is pressed, the information is transmitted to a remote monitoring server (not shown) connected for communication via an internet line (not shown). For this reason, the organization to which the service engineer belongs can collectively manage the information related to the air conditioner installation work, and can promptly respond to after-sales service, response when trouble occurs, information provision, and the like.

However, when the indoor unit binding application 74e, the design information database 74f, the actual information database 74g, and the like are transplanted into the air conditioning controller 3, and the switch button 16 is pressed by a service engineer or the like, the serial number data stored in the first EEPROM 25 is stored. It may be transmitted to the air conditioning controller 3. In such a case, the engineering computer 7 becomes unnecessary. That is, the service engineer determines the order of the indoor units 20 to be circulated in advance in the air conditioning controller 3 and arranges the installation position data in that order. And the service engineer etc. pushes the switch button 16 of the indoor unit 20 in the order. At this time, if the indoor unit binding application 74d associates the transmitted serial number data with the installation position data in order from the top, it can be the same as the building system 1 according to the previous embodiment. become.
