2-16-4. Automatic address setting from the outdoor
unit
When there are multiple outdoor units as shown in basic
wiring diagram 2
If the power can be turned ON separately for the
indoor and outdoor units in each system (indoor unit
addresses can be set without operating the comp-
ressor):
(1) Turn ON the indoor and outdoor unit power for re-
frigerant system 1.
Press and hold the automatic address setting button
(black) for 1 second or longer at the outdoor unit
where the power was turned ON.
Communication for automatic address setting begins.
LED 1 and 2 on the outdoor unit control PCB blink
alternately, and turn OFF when address setting is
completed.
<Approximately 4 – 5
minutes are required.>
(2) Next, turn ON the power only at the indoor and
outdoor units in a different system. Press the auto-
matic address setting button (black) on the outdoor
unit.
LED 1 and 2 on the outdoor unit control PCB blink
alternately, and turn OFF when address setting is
completed. Repeat the same procedure for each
system and complete automatic address setting.
(3) Operation using the remote controller is now
possible.
2-16-5. Indoor unit remote controller main-sub
setting
When multiple wall-mounted indoor units are installed
for group control in a simultaneous-operation multi
system, set the control PCB at the No. 2 and following
wall-mounted units to “Sub remote control”.
If a wired remote controller is used, set the wired
remote controller to “Sub”.
If 2 wireless remote controllers are used, set the
wireless PCB (DIP switch) on the second remote
controller to “Sub”.
