2-8-5. Indicating (marking) the indoor and outdoor unit combination number
Indicate (mark) the number after automatic address setting is completed.
(1) So that the combination of each indoor unit can be easily checked when multiple units are installed, ensure
that the indoor and outdoor unit numbers correspond to the system address number on the outdoor unit control
PCB, and use a magic marker or similar means which cannot be easily erased to indicate the numbers in an
easily visible location on the indoor units (near the indoor unit nameplates).
Example: (Outdoor) 1 - (Indoor) 1, 2...
(Outdoor) 2 - (Indoor) 1, 2...
(2) These numbers will be needed for maintenance.
Be sure to indicate them.
* Use the remote controller to check the addresses of the indoor units. Press and hold the
button and
button for 4 seconds or longer (simple settings mode).
Then press the button and select the indoor address. (Each time the button is pressed, the address
changes as follows: 1-1, 1-2, ... 2-1, 2-2, ....)
The indoor unit fan operates only at the selected indoor unit. Confirm that correct fan is operating, and indicate
the address on the indoor unit.
Press the
button again to return to the normal remote controller mode.
