2-8-4. Automatic address setting using the remote
controller
When the outdoor unit shown in “2-8-2. Basic wiring
diagram 2” is used for group control of multiple units,
use the remote controller to perform automatic address
setting. (During automatic address setting, “SETTING”
blinks on the remote controller display.)
Press the remote controller timer time button and
button simultaneously. (Hold for 4 seconds or
longer.) Then press the button. (Item code “AA”
appears: All systems automatic address setting.)
(Automatic address setting is performed in sequence
for all outdoor units from No. 1 to No. 30. When auto-
matic address setting is completed, the units return to
normal stopped status.)
To select each refrigerant system individually and per-
form automatic address setting, press the remote
controller timer time button and button simulta-
neously. (Hold for 4 seconds or longer.) Then press
either of the temperature setting / buttons.
(Item code “A1” appears: Individual system automatic
address setting)
Use either the or button to select the
outdoor unit to perform automatic address setting for.
(R.C.1 is displayed.) Then press the button.
(Automatic address setting is performed for refrigerant
system 1.) When automatic address setting for system
1 is completed, the system returns to normal stopped
status.
Again press the remote controller timer time button
and the button simultaneously.
Then in the same way as above (use the button
to display “R.C.2”), select the next system and perform
automatic address setting.
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 set-
tings mode).
Then press the button and select the indoor
address. (Each time the button is pressed, the add-
ress 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.
For details, refer to the separate manual.
