10-26-3. Checking indoor unit addresses
Use the remote controller to check the addresses of the indoor units. Press and hold the
button for 4 seconds or longer (simple settings mode, "ALL" appears on the remote controller). Then press the
button and select the indoor address.
(For the system addresses of the No. 1 outdoor unit, each time the button is pressed, the address changes as fol-
lows: 1-1, 1-2, ...)
The indoor unit fan operates only at the selected indoor unit. Confirm the indoor unit address. (For the system
addresses of the No. 2 outdoor unit, the displayed addresses are 2-1, 2-2, ...)
Press the
button again to return to the normal remote controller mode.
10-26-4. 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 removed to indicate the numbers in an
easily visible location on the indoor units (near the indoor unit nameplates).
Example: (Outdoor) 1 – (Indoor) 1, 2...
(2) These numbers will be needed for maintenance. Be sure to indicate them.
10-26-5. Setting a wired remote controller as a sub remote controller
Change the remote controller address connected on the reverse side of the remote controller switch PCB from the
Main position to the Sub position.
