PROBLEM TO BE SOLVED: To reduce the load of a temperature-setting operation for each indoor machine being made by a central control device. SOLUTION: In an air conditioning system 10, the operation of one or a plurality of air conditioners 11A-11D with one or a plurality of outdoor machines 13, 19, 24, and 28 and a plurality of indoor machines 14, 20, 21, 22, 25, 26, and 29 can be centrally controlled via a serial/parallel input/output device 17 by a central control device 12, and serial communication and parallel communication are mutually converted. In the air-conditioning system 10, the serial input/ output device stores the range of a setting temperature being determined for each operation mode for each of the plurality of indoor machines in advance and changes a setting temperature A to the range of the setting temperature being determined for the operation mode of the indoor machine when a signal for setting an arbitrary indoor machine to the setting temperature A in an arbitrary operation mode from a central control device. |
