2-16-6. Indoor unit address setting

• If multiple single-type units are installed in the same room the addresses can be set to prevent signal interference.
By coordinating the numbers of the indoor unit (wireless PCB) and remote controller addresses, up to 6 indoor
units can be controlled independently by their respective remote controllers.
Independent control is not possible when a simultaneous operation multi system is used.

• Checking the addresses

Press the remote controller address button to display the current address on the remote controller display.
If this address matches the indoor unit (wireless PCB) address, the buzzer will sound.
2
(If ALL is set, the buzzer will always sound.) If ALL is set, operation is possible regardless of the indoor unit address.
Point the remote controller toward the receiver (indoor unit) that you wish to operate, and send the operation signal.

• Remote controller address setting

Press and hold the address button for 4 seconds or longer
to display the address on the remote controller display. The
current address starts blinking.
The address changes each time the remote controller
address button is pressed: ALL
Set the address to match the remote controller you wish
to operate. When the SET button is pressed, the address
stops blinking and displays for 5 seconds. The buzzer
sounds if the address matches the indoor unit.

2-17. Caution
This unit may be used in a single-type refrigerant system where 1 outdoor unit is connected to 1 indoor unit,
and also in a system where 1 outdoor unit is connected to multiple indoor units (maximum 4 < Double-Twin >).
• This test run explanation describes primarily the procedure when using the wired remote controller.
• If link wiring is used, set the outdoor unit system address to allow the combination of indoor and outdoor units to
be identified. At the same time, indicate the indoor-outdoor unit combination number in a location where it can
be checked easily (near the indoor unit nameplates). (This number will be required for subsequent maintenance.
Refer to 2-22-2, -3, -4.)
• Request that the customer be present when the test run is performed. At this time, explain the operation manual
and have the customer perform the actual steps.
• Be sure to pass the manuals and warranty certificate to the customer.
• Check that the 220 - 240 V AC wiring is not connected to the inter-unit control wiring connector terminal.
If 220 - 240 V AC is accidentally applied, the indoor or outdoor unit control
PCB fuse (0.5 A for both indoor and outdoor units) will blow in order to
protect the PCB. Correct the wiring connections, then disconnect the 2P
connectors (indoor: blue, OC) (outdoor: blue, serial 1) that are connected
to the PCB, and replace them with 2P connectors (indoor: brown, EMG)
(outdoor: brown, serial 2). If operation is still not possible after changing the
brown connectors, try cutting the varistor (black) (both indoor and outdoor).
(Be sure to turn the power OFF before performing this work.)
