摘要： An indoor unit of an air conditioner includes a relay K2R switched by an indoor control circuit between an on state in which the relay K2R connects signal and power lines and an off state in which the relay K2R disconnects the signal and power lines. An outdoor unit of the air conditioner includes a relay K13R switched by an outdoor control circuit between an on state in which the relay K13R connects the outdoor control circuit to the AC power supply and an off state in which the relay K13R connects the outdoor control circuit to the signal line. The relay K2R is switched to the on state with the relay K13R in the off state. When the outdoor control circuit is started, the relay K13R is switched to the on state, and then the relay K2R is switched to the off state, thereby starting the outdoor unit.
