摘要： An air conditioning system includes a plurality of air conditioning indoor units installed in a target space, a plurality of remote control devices corresponding to the air conditioning indoor units, and a controller. The remote control device has a command input to set the corresponding air conditioning indoor unit or the remote control device. The controller performs a process based on the command input to the remote control device. Each remote control device includes a communicating unit that performs a communication with the corresponding air conditioning indoor unit, and a short range wireless communicating unit that performs a short range wireless communication with a communicating apparatus having a function of the short range wireless communication. The command is input by receiving a signal transmitted from the communicating apparatus by the short range wireless communication, at the short range wireless communicating unit.
