Address setting method
a. Indoor/outdoor transmission line
)
❉
Make sure to use shielded wire.
Connection of shielded wire:
For the grounding of shielded wire, apply jumper wiring between the grounding screw of OC, S-terminal of the
terminal block (TB3), and S-terminal of the system controller.
b. Centralized control transmission line
Apply jumper wiring between M1, M2 terminals of centralized control transmission line terminal blocks (TB7) on
each OC. On one OC only, replace the power selecting connector (CN41) with (CN40). Set the centralized control
switch (SW2-1) on the main board of all outdoor units to “ON.”
❉
Make sure to use shielded wire.
Connection of shielded wire:
Apply jumper wiring to connect the shielded earth to S-terminal of the terminal block (TB7) on each OC. Connect S-
terminal of the terminal block (TB7) on one OC with (CN40) connected to the earth screw ( ) of the electrical parts box.
c. MA remote controller wiring The same as 1. (1)
For 2-remote controller operation: The same as 1. (1)
For indoor unit group operation: The same as 1. (2)
d. LOSSNAY connection
Apply jumper wiring to connect M1, M2 terminals of the terminal block (TB5) on (IC) to the terminal block (TB5) on
the indoor/outdoor transmission line terminal block (TB5) on Lossnay (LC). (with non-polarity two wires)
❉
The interlocking registration of the indoor unit and Lossnay is required from the system controller. (For the
registration method, see the instruction manual of system controller.)
To connect ON/OFF remote controller only, interlocking registration from the remote controller is required.
e. Switch setting Address setting is required as follows.
Daisy-chain the M1 and M2 terminals of the indoor-outdoor transmission terminal block (TB3) on the outdoor unit (OC),
M1 and M2 terminals of the indoor-outdoor transmission terminal block (TB3) on the heat exchanger unit (OS), M1 and
M2 terminals of the indoor-outdoor transmission line terminal block (TB02) on the BC controller (BC), and M1 and M2
terminals of the indoor-outdoor transmission line terminal block (TB5) on each indoor unit. (with non-polarity two wires)

The lowest address of indoor unit
within refrigerant 50
• Set the lowest address within a
same group to the indoor unit
desired to be the main unit.
• The address of the indoor unit
connected to the sub BC
controller must be larger than that
of the indoor unit connected to
the main BC controller.
• If applicable, set the sub BC
controllers in an R2 system in the
following order:
(1) Indoor unit to be connected to
the main BC controller
(2) Indoor unit to be connected to
No.1 sub BC controller
(3) Indoor unit to be connected to
No.2 sub BC controller
Set the address so that (1) < (2) < (3)
Set to the main unit address within a
same group in serial order
[Main unit +1, +2, +3,....]
Use the address that equals the
sum of the smallest indoor unit ad-
dress out of all the indoor units that
are connected to the sub BC con-
troller and 50.
Outdoor unit a1
• When operating indoor units
with different function within a
same group, as-sign the
indoor unit with the most
plenty of function to the main
unit.
• Requires a branch-number
setting.
• Set the address not to be
overlapped with the indoor
unit address.
• To set the address to “100,”
set it to “50”.
• If the address of the heat ex-
changer unit or main BC con-
troller overlaps with the ad-
dress of the outdoor unit or
the sub BC controller, use an
unused address within the set-
ting range.
• The use of a sub BC controller
requires a main BC controller.
