PROBLEM TO BE SOLVED: To provide an air conditioning system in which modification of settings concerning to external input function can be dealt with easily and burden incident to modification of specifications can be reduced on the manufacturer side. SOLUTION: In the air conditioning system 1 comprising an indoor unit 4 installed in an air conditioning space, and controllers (C1, C2) provided in correspondence with the indoor unit 4 and having external input terminals 37a-37d, a normal mode or a set mode is selected in response to mode switching operation for an operating board 50. When a specified setting operation is performed for the operating board 50 under a state where the set mode is selected, a processing to be executed in response to an input signal from the external input terminal 37a-37d at the time of set mode is selected among a plurality of candidates based on that operation. When a signal is inputted from the external input terminal 37a-37d under a state where the normal mode is selected, the processing selected at the time of set mode is executed. |
