In a system with two or more HBCs, make
the settings for the indoor units in the fol-
lowing order.
(i) Indoor unit to be connected to the main
HBC
(ii) Indoor unit to be connected to the sub
HBC 1
(iii) Indoor unit to be connected to the sub
HBC 2
(iv) Indoor unit to be connected to the sub
HBC 3
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.)
RC 101 to Add 100 to the main unit address in
150 the group
RC 151 to Add 150 to the main unit address in
200 the group
OC
51 to 100  Set the address to "the smallest indoor unit
address in the same refrigerant circuit sys-
tem + 50."
HB 51 to 100 OC +1
HS Assign an address that equals the sum of the
smallest address of the indoor units that are
connected to the sub HBC and 50.
When 2 remote controllers are connected to the sys-
tem
Refer to the section on Switch Setting.
Performing a group operation (including the group
operation of units in different refrigerant circuits).
Refer to the section on Switch Setting.
4) Switch setting
Address setting is required as follows.
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.
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
overlaps any of the address-
es that are assigned to the
outdoor units or to the sub
HBC, use a different, un-
used address within the set-
ting range.
The use of a sub HBC re-
quires the connection of a
main HBC.
