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).

In a system with a sub BC con-
troller, make the settings for the
indoor units in the following or-
der.
(i) Indoor unit to be connected to
the main BC controller
(ii) Indoor unit to be connected to
sub BC controller 1
(iii) Indoor unit to be connected to
sub BC controller 2
Make the settings for the indoor
units in the way that the formula "(i)
< (ii) < (iii)" is true.
Œ
Assign an address smaller than that of
the indoor unit that is connected to the
M-NET remote controller.
Œ
Enter the same indoor unit group set-
tings on the system controller as the
ones that were entered on the MA re-
mote controller.

ignate the indoor unit in the group with
the greatest number of functions as the
main unit.
ΠPort number setting is required.
ΠAddresses that are assigned to the in-
door units that are connected to the sub
BC controller should be higher than the
addresses that are assigned to the in-
door units that are connected to the
main BC controller.

after assigning an address to
all indoor units. None of these addresses may over-
lap any of the indoor unit addresses.

Assign sequential address to the
outdoor units in the same refrig-

ΠThe outdoor units are automati-
cally designated as OC and
OS.(Note)
Œ
To set the address to 100, set it to 50.
ΠIf the addresses that is assigned to the
main BC controller overlaps any of the
addresses that are assigned to the out-
door units or to the sub BC controller,
use a different, unused address within
the setting range.
ΠThe use of a sub BC controller requires
the connection of a main BC controller.
