An air-conditioning system (1) is provided with a display unit (21) for showing the operating state of an air conditioner (10) to a user. The display unit (21) is configured to display during rotation operation a rotation sign (S1) indicating that the rotation operation is being executed. With the above-described configuration, it is possible to prevent the user from worrying unnecessarily when the air conditioner is brought into a resting state by the rotation operation.
