Thus, it is possible to provide a more convenient air conditioning system for the user. Here, if the bathroom air-conditioning unit or the undressing room air-conditioning unit and the controller are configured to communicate by radio waves, it is necessary to perform wiring work such as a communication line connecting the bathroom air-conditioning unit or the undressing room air-conditioning unit and the controller. There is no need to operate the controller toward the bathroom air-conditioning unit or the dressing room air-conditioning unit by using radio waves, so that operability is improved. Further, when a plurality of the controllers are provided, specifically, the controller includes at least a first controller and a second controller, and the first controller and the second controller are independently provided. Even when communication with the control unit is possible, it is possible to provide a user-friendly air-conditioning system by suppressing battery consumption as described above. Further, the first controller and the second controller include a display unit for notifying an operation state of the bathroom air conditioning unit,
The display unit is configured not to perform the display after a predetermined time has elapsed since a switch for operating the bathroom air-conditioning unit provided in the first controller and the second controller is pressed. After a lapse of a predetermined time, the first controller and the second controller do not store the operation status of the bathroom air conditioning unit. Therefore, the first controller is operated to start the operation of the bathroom air-conditioning unit, for example, the heating operation is started. After a predetermined time has elapsed, the display of the heating disappears on the display unit of the first controller. Operate other driving,
For example, if the operation mode is changed to the ventilation operation, the first controller does not store the information on the heating operation, so that if the confirmation switch is pressed to confirm the current operation state, the indication of heating is erroneously displayed. There is no inconsistency with the current operation status of the bathroom unit (in this case, ventilation operation).
