automatic address setting, "SETTING" blinks on the remote
controller display.)
● Press the remote controller timer time
button simultaneously. (Hold for 4 seconds or longer.) Then

10-8-5. Indicating (marking) the indoor and outdoor unit
combination number
Fig. 10-7
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...
(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 for 4 seconds or longer (simple settings mode).
Then press the
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. Confi rm
that correct fan is operating, and indicate the address on
the indoor unit.
Press the
