Important Check the setting for the central control switch SW2-1 on the M-NET outdoor unit.
(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 model
units.
Refer to the K-transmission converter Installation manual for details.
1 Be sure to set the BAC-HD150 address to "000."
2 Be sure to set the K-control air conditioning unit connection setting on the BAC-HD150 to Yes (set via the
Setting Tool).
When the above setting is made, enter the K-transmission converter address.
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 When making the group settings for the K-control units, make the group number and the lowest address of
the indoor units within the group the same.
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 units cannot be connected to the same transmission lines as the
other types of units.
6 Depending on the number of K-control units and transmission line length, a relay board may be required.
Refer to the System Design/Manual (control version) for details.
7 LOSSNAY units cannot be connected if they are connected to the K-control kit.
8 Remote controller addresses do not need to be included in the group setting for the K-control units.
Note A-control jet burner models cannot be controlled.
Some models of units cannot be controlled.
* Main and sub system controllers (M-NET)
BAC-HD150 can only be used as the main system controller, but not as a sub system controller.
Main system controller (Main SC)
Main SC refers to a controller that controls all other system controllers including the units they control. If a given system
has only one system controller, that controller becomes the main SC. Group settings and interlock settings can only be
made from a main SC.
Sub system controller (Sub SC)
Sub SC refers to a system controller that is controlled (including the units it controls) by a main SC.

Group Group
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.
Assign an address that equals the lowest indoor unit address in the group plus 50.
Assign an address that equals the address of the outdoor unit in the same refrigerant
system plus 1.
Assign an arbitrary but unused address to each of LOSSNAY units after assigning an
address to all indoor units.
Set the address in the same way as with the indoor units. An M-NET adapter (sold
separately) is required.
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 a sub remote controller.
Address setting is not required.
Connection of two remote controllers requires the main/sub setting for each
controller to be made.
Assign an address that equals the lowest number of the group to be controlled +200.
Assign an address to all M-NET indoor units (incl. LOSSNAY units) first, and then
assign addresses to the K-control indoor unit, starting with the address after the last
address.
Assign the same address as the lowest main K-control indoor unit address within the
same group.
Assign an address that equals the lowest address of the K-control indoor units +200.
BAC-HD150 is exclusively for use as a main SC. It cannot be used as a sub SC
Group
or controlled from a main SC.
