Air conditioner

Abstract

An air conditioner includes an indoor unit installed on an indoor side, an outdoor unit installed on an outdoor side, a human detector that detects a person in a room, and a remote controller that performs radio communication with the indoor unit, and the air conditioner conditions the indoor air. The indoor unit includes an indoor unit control section that controls the indoor unit, a diagnostic section that diagnoses whether an operating state of the human detector is normal or abnormal, and a communication section that performs radio communication with the remote controller. The human detector includes a plurality of infrared sensors, a rotary table that supports each of the infrared sensors, and a human detector control section that controls the human detector. The diagnostic section diagnoses whether the operating state of the human detector is normal or abnormal by comparing the detected results between the respective infrared sensors on receiving a trigger signal transmitted from the remote controller.
