Notes
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
the greatest number of functions as the
main unit.
Port number setting is required.
Assign an address higher than those of
the indoor units that are connected to
the MA remote controller.
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
HBC controller should be higher than
the addresses that are assigned to the
indoor units that are connected to the
main HBC 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 HBC controller overlaps any of
the addresses that are assigned to the
outdoor units or to the sub HBC control-
ler, use a different, unused address
within the setting range.
The use of a sub HBC controller re-
quires the connection of a main HBC
controller.
