attached to the front panel.
All indoor units connected with the outdoor unit will operate automatically after powering on.
To ensure safety, ensure that the indoor unit installation has been completed.

will be indicated on the display of the
remote controller and the unit will not operate normally).
After turning on the power supply, do not touch any switches excluding button switches and changeover
switches when setting the outdoor unit PCB (A2P).
