<p>When the indoor-unit-side control board (3) starts to receive power, it is determined whether communication from the outdoor-unit-side communication circuit (10) to the indoor-unit-side communication circuit (9) is performed normally. If the communication from the outdoor-unit-side communication circuit to the indoor-unit-side communication circuit is performed normally, it is determined that the air conditioner is operated under the outdoor-unit power receiving system and power-supply control is performed. If the communication from the outdoor-unit-side communication circuit to the indoor-unit-side communication circuit is not performed normally, it is determined that the air conditioner is operated under the indoor-unit power receiving system and power-supply control is performed.</p> |
