(4) Wiring method
1) Indoor/outdoor transmission line
Daisy-chain terminals M1 and M2 of the terminal block
for indoor-outdoor transmission line (TB3) on the outdoor
units (OC and OS), of the terminal block for indoor-out-
door transmission line (TB02) on the HBC controller
(HB), and of the terminal block for indoor-outdoor trans-
mission line (TB5) on each indoor unit (IC). (Non-polar-
ized two-wire)
Œ
Only use shielded cables.
The outdoor units in the same refrigerant circuit are au-
tomatically designated as OC and OS in the order of ca-
pacity from large to small (if two or more units have the
same capacity, in the order of address from small to
large).
Shielded cable connection
Daisy-chain the ground terminal ( ) on the outdoor
units (OC and OS), the S terminal of the terminal block
(TB02) on HB, and the S terminal of the terminal block
(TB5) on the indoor unit (IC) with the shield of the shield-
ed cable.
2) Transmission line for centralized control
No connection is required.
3) MA remote controller wiring
Same as [5] 1.
When 2 remote controllers are connected to the sys-
tem
Same as [5] 1.
Group operation of indoor units
Same as [5] 1.
4) LOSSNAY connection
Connect terminals M1 and M2 on the terminal block
(TB5) on the indoor unit (IC) to the appropriate terminals
on the terminal block (TB5) on LOSSNAY (LC). (Non-po-
larized two-wire)
Œ
Interlock setting between the indoor units and LOSS-
NAY units must be entered on the remote controller. (Re-
fer to "IV [3] Interlock Settings via the MA Remote
Controller" or the installation manual for the MA remote
controller for the setting method.)
5) Switch setting
Address setting is required as follows.
(5) Address setting method
The outdoor units in the same refrigerant circuit are automatically designated as OC and OS.
They are designated as OC and OS in the descending order of capacity (ascending order of address if the capacities are the
same).

1 Indoor
unit Main unit IC 01 to 50
Œ
Assign the smallest address to the main
unit in the group.
Œ
Port number setting is
required
Œ
To perform a group op-
eration of indoor units
that feature different
functions, designate
the indoor unit in the
group with the greatest
number of functions as
the main unit.
00
Sub unit Assign sequential numbers starting with
the address of the main unit in the same
group +1. (Main unit a1, main unit
a2, main unit a3, etc.)
2 LOSSNAY LC 01 to 50 Assign an arbitrary but unique address to
each of these units after assigning an ad-
dress to all indoor units. None of these addresses may
overlap any of the indoor unit
addresses. 00

4 Outdoor unit OC
OS 51 to 100
Œ
Assign sequential address to the outdoor
units in the same refrigerant circuit.
Œ
The outdoor units are automatically des-
ignated as OC and OS.(Note)
Œ
To set the address to 100,
set the rotary switches to 50.
Œ
If the address that is as-
signed to the HBC controller
overlaps any of the address-
es that are assigned to the
outdoor units, use a differ-
ent, unused address within
the setting range.
