Type and method of switch setting
Switch setting vary depending on the system configuration. Make sure to read
“[3] Examples of system connection”
before conducting electrical work. Turn off the power before setting the switch. Operating the switch while the unit is
being powered will not change the setting, and the unit will not properly function.
1. Address setting is not required for a single refrigerant system (with a few exception).
2. When setting M-NET remote controller address to “200,” make it “00.”
3. When setting the outdoor unit and outdoor auxiliary unit address to “100,” make it “50.”
4. When an address in a system overlapped with the outdoor unit or BC controller (Main) address of other refrigerant system,
choose an another address within theset range that is not in use (with a few exceptions).
5. When controlling the K-control units;
(1) A K-transmission converter (Model name: PAC-SC25KA) is required. To set the address for the K-transmission converter,
set it to thelowest address of the K-control unit to be cont 200.
(2) Set the address of the system controller (G-50A) to “0.” The K-control unit can only be controlled by the system controller
with theaddress “0.”
(3) To control both K-control unit and M-NET model unit, make the address of the K-control unit larger than that of the indoor
unit of M-NET model.
Group-register on the system controller so that the group No. and the lowest address of the K-controlled indoor units
belonging to thegroup will be identical.
Use the address that equals the sum of the smallest indoor
unit address in the same refrigerant system and 50.
Use the address that equals the sum of the smallest
address of the indoor unit out of all the indoor units
that are connected to the BC controller and 50.
When a sub BC controller is connected, the automatic
start up function will not be available.

Use the address that equals the sum of the address of the

BC controller (Main)
Choose any number within the range of addresses shown left.
However when using with the upper SC setting, or wishing to
control the k-control units, set to “0.”
Assign the smallest address to the indoor unit to
become the main unit within the same group, and
then use sequential numbers to assign an address
to all the indoor units in the group. (Note 5)
If applicable, set the sub BC controllers in an R2
system in the following order:
(1) Indoor unit to be connected to the main BC controller
(2) Indoor unit to be connected to No.1 sub BC controller
(3) Indoor unit to be connected to No.2 sub BC controller
Set the address so that (1) < (2) < (3)
Assign any unused address after setting all indoor units.
Set to the lowest address of the indoor main unit
within the same group + 150.
Set to the lowest No. of the group to be cont “200.”
Set to the lowest No. of the group desired tobe cont “200.”
Choose any number within the range of addresses shown left.
Choose any number within the range of ad-dresses shown left.
Choose any number within the range of addresses shown left.
Set to the lowest address of the indoor main unit
within the same group + 100.
No address setting required. (When operating with 2 remote controllers,
the main/sub selector switch must be set.
