Assign an address smaller than that of
the indoor unit that is connected to the
M-NET remote controller.
Enter the same indoor unit group set-

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.
It is not necessary to set the 100s
digit.
To set the address to 200, set it to
00.
None of these addresses may over-
lap any of the indoor unit addresses.
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 out-
door 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.
