- the outdoor control unit 21 turns on the relay MR10 of the indoor unit 10 to turn on the indoor unit 10 side force train via the signal line L3.
- the relay MRM10 is turned on after a predetermined time (for example, several tens of msec) after the start relay MR30 is opened.
- the indoor control unit 12 indicates that the communication wiring (L1 to L3) is incorrect. Therefore, the display unit 13 notifies the user of the incorrect wiring, so that the operator can know the cause of the malfunction at the time of installation and can take quick action.
- the external power source 30 is connected to the indoor unit 10, but an external power source may be connected to the outdoor unit.
- the display unit 13 is used as a notification unit.
- the notification unit is not limited to this, and may be a notification by voice or buzzer sound! / ,.
