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 compressor):
(1) Turn ON the indoor and outdoor unit power for refrigerant 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.
(2) Next, turn ON the power only at the indoor and outdoor units in a different system. Press the automatic 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".
