2. M-NET Address settings

The need for address settings and the range of address setting depend on the configuration of the system.

*1. If a given address overlaps any of the addresses that are assigned to other units, use a different, unused address within the
setting range.
*2. To set the outdoor unit address or the auxiliary outdoor unit address to "100," set the rotary switches to "50."
*3. To set the M-NET remote controller address to "200," set the rotary switches to "00."
*4. Some models of indoor units have two or three control boards.
Assign an address to the No.1, No. 2, and No. 3 control boards so that the No. 2 control board address equals the No. 1 control
board address plus 1, and that the No. 3 control board address equals the No. 1 control board address plus 2.
*5. 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).
*6. No address settings are required for units in a system with a single outdoor unit (with some exceptions).
Address setting is required if a sub BC controller is connected.

IC
0, 01 to
Assign the smallest address to the main indoor unit in the
*1 *4 *6
50
group, and assign sequential address numbers to the rest
of the indoor units in the same group.
In an R2 system with a sub BC controller, make the set-
tings 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
formula "(i) < (ii) < (iii)" is true.
LC
0, 01 to
Assign an arbitrary but unique address to each of these
*1 *4 *6
50
units after assigning an address to all indoor units.
RC
101 to
Add 100 to the smallest address of all the indoor units in
150
the same group.
RC
151 to
Add 150 to the smallest address of all the indoor units in
*3
200
the same group.
MA
No address settings required. (The main/sub setting must be made if
2 remote controllers are connected to the system.)
OC
0, 51 to
Assign an address that equals the lowest address of the in-
*1 *2
door units in the same refrigerant circuit plus 50.
OS
100
Assign sequential addresses to the outdoor units in the
*6
same refrigerant circuit. The outdoor units in the same re-
frigerant circuit are automatically designated as OC and
*5
OS.
BC
0, 51 to
Assign an address that equals the address of the outdoor
*1 *2
100
unit in the same refrigerant system plus 1.
*6
If a given address overlaps any of the addresses that are
assigned to the outdoor units or to the sub BC controller,
use a different, unused address within the setting range.
BS1
51 to
Assign an address to both the sub BC controller 1 and 2
*2
BS2
100
that equals the lowest address of the indoor units that
are connected to each of them plus 50.
If a sub BC controller is connected, the automatic startup
function is not available.
GR
201 to
Assign an address that equals the sum of the smallest
SC
250
group number of the group to be controlled and 200.
SR
Assign an arbitrary but unique address within the range
SC
listed on the left to each unit.
AN
Assign an address that equals the sum of the smallest
SC
group number of the group to be controlled and 200.
ST
Assign an arbitrary but unique address within the range
SC
listed on the left to each unit.
TR
0, 201 to
Assign an arbitrary but unique address within the range
SC
250
listed on the left to each unit. The address must be set to
"0" to control the K-control unit.
SC
201 to
Assign an arbitrary but unique address within the range
250
listed on the left to each unit.
