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).

Setting method 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 address that is as-
signed to the HBC controller
and Sub-HBC overlaps any
of the addresses that are as-
signed to the other units,
use a different, unused ad-
dress within the setting
range.
