Abstract
An indoor unit of an air conditioner includes a relay KR switched by an indoor control circuit between an on state in which the relay KR connects signal and power lines and an off state in which the relay KR disconnects the signal and power lines. An outdoor unit of the air conditioner includes a relay KR switched by an outdoor control circuit between an on state in which the relay KR connects the outdoor control circuit to the AC power supply and an off state in which the relay KR connects the outdoor control circuit to the signal line. The relay KR is switched to the on state with the relay KR in the off state. When the outdoor control circuit is started, the relay KR is switched to the on state, and then the relay KR is switched to the off state, thereby starting the outdoor unit.
