(K-control units and K-control remote control addresses are excluded.)
Address setting method
M-NET
address
Indoor unit
Assign the lowest address to the main indoor unit in the group, and assign sequential
addresses to the rest of the indoor units in the same group.
1 ~ 50
Outdoor unit
Assign an address that equals the lowest indoor unit address in the same refrigerant
group plus 50.
51 ~ 100
Auxiliary outdoor unit
(BC controller etc.)
Assign an address that equals the address of the outdoor unit in the same refrigerant
system plus 1.
52 ~ 100
OA processing unit/
LOSSNAY
Assign an arbitrary but unused address to each of these units after assigning an
address to all indoor units.
1 ~ 50
Mr.Slim outdoor unit

adapter (sold separately).
1 ~ 50
M-NET remote controller
Assign an address that equals the address of the main indoor unit with the lowest
address in the group plus 100.
Add 150 in stead of 100 to set the address for a sub remote controller.
101 ~ 200
MA remote controller
Address setting is not required.
Connection of two remote controllers requires the main/sub setting for each
controller to be made.
–
Sub system controller
Assign an address that equals the group number of the smallest controlled group
plus 200.
201 ~ 250
DIDO controller
(PAC-YG66DCA)
Assign an arbitrary but unused address to the controller after completing the address
setting for the units with an address between 1 and 50.
The number of controllable units changes with the number of channels used.
1 ~ 50
PI controller
(PAC-YG60MCA)
Assign an arbitrary but unused address to the controller after completing the address
setting for the units with an address between 1 and 50.
1 ~ 50
AI controller
(PAC-YG63MCA)
Assign an arbitrary but unused address to the controller after completing the address
setting for the units with an address between 1 and 50.
1 ~ 50
K-control indoor unit
Assign an address to all indoor units connected to the M-NET lines (incl. LOSSNAY
units) first, and then assign addresses to the K-control indoor units, starting with the
address after the last address.
1 ~ 50
K-control remote
controller
Assign an address as the lowest address of the K-control indoor units in the same
group.
1 ~ 50
K-transmission converter
Assign an address that equals the lowest K-control indoor unit address plus 200.
201 ~ 250
Important
Check that the setting for the central control switch SW2-1 on the M-NET outdoor unit is set to “ON.”
(Refer to the outdoor unit Installation Manual for the detailed information about dip switch settings.)
Note the following when using a K-transmission converter (model: PAC-SC25KAA) to control the K-control units.
Refer to the K-transmission converter Installation Manual for details.
1
Be sure to set the GB-50ADA address to “000.”
2
Set the “K-transmission converter connection setting” (to be set from a Main controller) to ON (with a
connection to K-transmission converter).
When this setting is set to ON, an address field will appear. Enter the K-transmission converter address in the
field.
3
Assign addresses to the K-control air conditioners so that they are larger than the addresses that are
assigned to the M-control indoor units.
4
Make the group settings for K-control units so that the group number equals the lowest address of the indoor
units within the group.
5
If the K-control Y series units and other types of units (K-control Mr. Slim) are used in combination, a relay
board is required. The K-control Y series of units and other types of units cannot be connected to the same
transmission line.
6
A relay board may be required, depending on the number of K-control units and the length of transmission
lines. Refer to the System Design Manual (control version) for details.
7
LOSSNAY units that are connected to the general K-control kit cannot be connected.
8
Remote controller addresses is not required in the group setting for the K-control models.
Note
A-control jet burner models cannot be controlled.
Some models cannot be controlled.
Main system controllers, such as the AG-150A, cannot be connected to a M-NET system that is controlled by the
GB-50ADA.
When connecting both GB-50ADA and BAC-HD150 (BM ADAPTER) to the same M-NET system, certain
restrictions apply. Consult your dealer for details.
