Therefore, the control unit 50 includes the controller 28.
Or commands from the user terminal device 30 (operation start operation, operation stop operation, set temperature of the room temperature, etc.), the room temperature detected by the room temperature sensor 21, and the room humidity detected by the room humidity sensor 22 Based on this, the operation of the air conditioner 1 is controlled. As described above, the air conditioner 1 of the present embodiment not only changes the operation state based on the commands from the controller 28 (operation start operation, operation stop operation, indoor temperature set temperature, etc.), The operation state is changed based on an operation change command (operation start operation, operation stop operation, indoor temperature set temperature, etc.) supplied from the terminal device 30.

Here, the controller 28 is provided with a display unit, a temperature adjustment unit, an operation start button, and a stop button. The controller 28 includes an operation selection unit, an air volume selection unit,
And a wind direction selector.

An operation display unit, a set temperature display unit, and an operation mode display unit are displayed on the display unit. The operation selected by the operation selection unit (automatic, cooling, heating, dehumidification, and blowing operation) is displayed on the operation display unit. Moreover, the temperature changed by operating the temperature adjustment part is displayed on the set temperature display part.

The temperature adjustment unit changes the set temperature. The temperature adjustment unit can be operated to increase the set temperature, or the temperature adjustment unit can be operated to decrease the set temperature. The operation selected by the operation selection unit is started by pressing the operation start button, and the operation is stopped by pressing the stop button during the operation.

The operation selection unit of the controller 28 can be switched between automatic, cooling, heating, dehumidification and ventilation.

Therefore, in the air conditioner 1, the operation in the forced operation mode, the operation in the notification mode, and the operation in the absence notification mode are not performed simultaneously.

In the forced operation mode, when the room is in a high temperature state or a high humidity state, the forced operation is automatically started based on the room temperature and the room humidity. Therefore, when the operation mode is switched to the forced operation mode, the forced operation is automatically started even when the user does not perform the operation start operation by the controller 28 or the terminal device 30 when the room is in a high temperature state or a high humidity state. As a result, the room temperature and the room humidity decrease.

In the notification mode, when the room is in a high temperature state or a high humidity state, a notification that prompts the start of operation is automatically performed based on the room temperature and the room humidity. As a notification to prompt the start of operation, for example, the content “The room is hot. Please start cooling operation” is notified by voice from the indoor unit 2 or displayed on the display unit of the indoor unit 2 Is done.

In the absence notification mode, when there is no person in the room detected by the human detection sensor 25 and the operation of the air conditioner 1 is continued for a predetermined absence time, absence information indicating that there is no person in the room Is supplied to the terminal device 30 of the user. In the air conditioner 1 of this embodiment, when absence information is supplied to the user's terminal device 30 in the absence notification mode, for example, as the absence information, “the air conditioner is operated in a state where there is no person in the room” "Is supplied to the terminal device 30 of the user and displayed on the display screen of the terminal device 30.
At this time, since the absence information supplied from the air conditioner 1 is stored in the user's terminal device 30, after the absence information is once supplied from the air conditioner 1, the user
