In an air conditioner, one of a linkage mode or a non-linkage mode is selected by a user as a control mode of an external device. In the air conditioner, when the linkage mode is selected, on/off control of the external device by using a human detection sensor is permitted during operation, whereas on/off control of the external device by using the human detection sensor is inhibited during suspension of operation. In the air conditioner, when the non-linkage mode is selected, on/off control of the external device by using the human detection sensor is always permitted, irrespective of whether the air conditioner is in operation or not.

Air conditioner

In an air conditioner, an auxiliary circuit configured to prevent a current flow in a power supply wiring in an operation stop period and to determine whether to adapt an outdoor unit to a unit that is able to transition to a standby mode, is provided on the power supply wiring.

A ceiling embedded type air conditioner is embedded in a ceiling surface and includes an outlet that blows out air conditioned air toward an indoor space, and a louver capable of changing a blow-out vertical direction of the air conditioned air at the outlet. If a state in which a wind direction position of the louver is set so that it is oriented to a wind direction position continues for a first prescribed time or longer, then the louver is temporarily changed to a wind direction position more downward than the wind direction position, and once again changed to the wind direction position.
