An indoor unit includes an indoor side transmitting and receiving section, a relay which is put in a closed state in a standby state, and an indoor control section which controls the relay on the basis of an output of the indoor side transmitting and receiving section. An outdoor unit includes an outdoor side transmitting and receiving section, and a power circuit. Then, the indoor control section of the indoor unit does not bring the relay into the closed state upon determining that the connection wiring lines which connect the indoor unit with the outdoor unit are miswired on the basis of a reception output of the indoor side transmitting and receiving section when operation starts from a standby state in which the supply of power of the outdoor unit is stopped.
