(5) Address setting method
The heat source 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).

Assign the smallest address to

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.
Assign an address smaller than that of
the indoor unit that is connected to the
ME remote controller.
Enter the same indoor unit group set-
tings on the system controller as the
ones that were entered on the MA re-
mote controller.
To perform a group operation of indoor
units that have different functions, des-
ignate the indoor unit in the group with

Make the initial settings for the indoor
unit group settings via the system con-
troller.
To perform a group operation of indoor
units that have different functions, des-
ignate the indoor unit in the group with
the greatest number of functions as the
main unit.
Port number setting is required.
Addresses 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.

Assign sequential address to the
heat source units in the same
refrigerant circuit.
The heat source units are auto-
matically designated as OC and
OS.(Note)
To set the address to 100, set it to 50.
If the addresses that is assigned to the
main BC controller overlaps any of the
addresses that are assigned to the heat
source units or to the sub BC controller,
use a different, unused address within
the setting range.
The use of a sub BC controller requires
the connection of a main BC controller.
