2. Address settings
(1) Address settings table
The need for address settings and the range of address setting depend on the configuration of the system.
*1 No address settings are required for units in a system with one outdoor (heat source) unit (with some exceptions).
Address setting is required if a sub BC controller is connected.
*2 To set the M-NET remote controller address to "200", set it to "00".
*3 To set the outdoor (heat source) unit or auxiliary unit address to "100", set it to "50".
*4 If a given address overlaps any of the addresses that are assigned to other outdoor (heat source) units, use a dif-
ferent, unused address within the setting range (with some exceptions).
*5 Some indoor units have 2 or 3 controller boards that require address settings.
(1) The address to be assigned to the No.1 controller board (by the power supply terminal block) must be 1 smaller
than that to the No.2 controller board.
(2) No. 2 controller board address must be equal to the sum of the No. 1 controller board address and 1, and the
No.3 controller board address must equal to the No. 1 controller address and 2.
Unit or controller Address setting
range Setting method Ad-
dress
setting
Indoor
unit Main/sub unit 0, 01 to 50
*1
Assign the smallest address to the main indoor unit in the
group, and assign sequential address numbers to the rest of
the indoor units in the same group.
*5
In an R2 system with a sub BC controller, make the settings
for the indoor units in the following order.
(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 for-
mula "(i) < (ii) < (iii)" is true.
00
LOSSNAY , OA processing
unit Assign an arbitrary but unique address to each of these
units after assigning an address to all indoor units. 00
M-NET
remote
controller Main remote
controller 101 to 150 Add 100 to the smallest address of all the indoor units in
the same group. 101
Sub remote
controller 151 to 200
*2
Add 150 to the smallest address of all the indoor units in
the same group.
MA remote controller No address settings required. (The main/sub setting must be made if 2 re-
mote controllers are connected to the system.) Main
Outdoor (heat source) unit 0, 51 to
100
*1,*3,*4
Assign an address that equals the sum of the smallest ad-
dress of the indoor units in the same refrigerant system
and 50. 00
Auxiliary
unit BC controller
(main) 0, 52 to 100
*3*4
Assign an address that equals the sum of the address of
the outdoor (heat source) unit in the same refrigerant sys-
tem and 1.
BC controller
(sub) Assign an address that equals the sum of the smallest ad-
dress of the indoor units that are connected to the sub BC
controller and 50.
If a sub BC controller is connected, auto-startup function
will not be available.
System
controller System remote
controller 201 to 250 Assign an arbitrary but unique address within the range
listed on the left to each unit. 201
ON/OFF remote
controller Assign an address that equals the sum of the smallest
group number of the group to be controlled and 200.
Schedule timer
(compatible with
M-NET) Assign an arbitrary but unique address within the range
listed on the left to each unit. 202
Central controller
G-50 0, 201 to 250 Assign an arbitrary but unique address within the range
listed on the left to each unit. The address must be set to
"0" to control the K-control unit. 000
LM adapter 201 to 250 Assign an arbitrary but unique address within the range
listed on the left to each unit. 247
