5) Switch setting
Address setting is required as follows.
Setting method
Assign the smallest address to the main unit
in the group.
In a system with two or more HBC control-
lers, make the settings for the indoor units
in the following order.
(i) Indoor unit to be connected to the main
HBC controller 1
(ii) Indoor unit to be connected to sub HBC
controller 1
(iii) Indoor unit to be connected to the main
HBC controller 2
(iv) Indoor unit to be connected to sub HBC
controller 2
Make the settings for the indoor units in the
way that the formula "(i) < (ii) < (iii) < (iv)" is
true.
Assign sequential numbers starting with the
address of the main unit in the same group
+1. (Main unit address +1, main unit address
+2, main unit address +3, etc.)
Assign an arbitrary but unique address to
each of these units after assigning an address
to all indoor units.
Add 100 to the main unit address in
the group
Add 150 to the main unit address in
the group
Assign sequential address to the outdoor
units in the same refrigerant circuit.
OC +1
Assign an address that equals the sum of the
smallest address of the indoor units that are
connected to the sub HBC controller and 50.

Notes
Port number setting is
required
To perform a group op-
eration of indoor units
that have different func-
tions, set the indoor unit
in the group with the
greatest number of
functions as the main
unit.
None of these addresses may
overlap any of the indoor unit
addresses.
It is not necessary to set the
100s digit.
To set the address to 200,
set the rotary switches to 00.
To set the address to 100,
set the rotary switches to 50.
If the addresses that is as-
signed to the main HBC
controller overlaps any of
the addresses that are as-
signed to the outdoor units
or to the sub HBC controller,
use a different, unused ad-
dress within the setting
range.
The use of a sub HBC con-
troller requires the connec-
tion of a main HBC
controller.
