Abstract
An air conditioner includes a remote controller that performs bidirectional communication using radio waves with an air-conditioner main body. The air-conditioner main body includes a main-body receiver that receives a control signal from the remote controller and a main-body transmitter that transmits operating information to the remote controller. The remote controller includes a remote-control transmitter that transmits a control signal to the main-body receiver, a remote-control receiver that receives the operating information from the main-body transmitter, a display unit that displays the operating information, a display controller that controls the display unit. The display controller displays, on the display unit, the operating information when the display controller receives the operating information from the main-body transmitter, and an indication of communication error when the display controller failes to receive the operating information, when communication between the remote controller and the air-conditioner main body is not established.
