Before installing the controller, please read this Installation Manual carefully to ensure
proper operation. Retain this manual for future reference.
This manual describes how to install the centralized controller and wiring. Before installing the controller, read the
1 Safety Precautions section carefully to ensure proper installation.
1 Safety Precautions
Safety symbols used in this manual
The following symbols are used in this manual to indicate the type and severity of potential consequences that may result when
given instructions are not followed exactly as stated.
WARNING
CAUTION
Retain the Installation Manual and the Instruction Book for future reference. Make sure both the Installation Manual and the
Instruction Book are passed to any future air condition system users.
Indicates a risk of death or serious injury.
Indicates a risk of injury or damage to the controller.
WARNING
The controller must be professionalling installed.
Improper installation by an unqualified person may result in
electric shock or fire.
Make sure the controller is securely mounted so that it
will not fall.
Only use specified cables. Securely connect each
cable so that the weight of the cable is not applied to
the connectors.
Loose or improper connections may result in heat
generation or fire.
Do not attempt to modify or repair the controller.
Modification or improper repair may result in electric shock
or fire.
Consult your dealer when repairs are necessary.
Securely install the controller according to the
installation manual.
Improper installation may result in electric shock or fire.
Electric work must be perform by authorized
personnel according to the local regulations and the
instructions detailed in the installation manual.
Inadequate circuit capacity or improper installation may
result in electric shock or fire.
Ask your dealer or an authorized technician to move
the controller.
Improper installation may result in electric shock or fire or
damage to the controller.
CAUTION
Do not install the controller where there is a risk of
flammable gas.
If the leaked gas accumulates around the controller, it may
ignite and cause an explosion.
Do not use the controller in an environment high in oil,
steam, or sulfuric gas.
These substances may have adverse effects on the
performance of the controller or damage its parts.
When installing the controller in a hospital or communication facility, take appropriate measures to reduce noise
interference.
Inverter equipment, generators, high-frequency medical equipment, or radio communication equipment may interfere with
the normal operation of the controller, or the noise from the controller may interfere with the medical practice or cause
image distortion and static noise.
To prevent over-heating and fire, perform wiring so
that the weight of the cable will not strain the
connectors.
Seal the wire lead-in port with putty to prevent the
entry of dew, water, and insects to avoid electric shock
or malfunction of the controller.
Do not wet the controller.
Water may damage the controller and cause an electric
shock.
Do not install this controller where the ambient
temperature exceeds 40°C (104°F) or drops below 0°C
(32°F).
To prevent deformation and malfunction, install the
controller out of direct sunlight.
AG-150A should be installed no higher than 1.8 m from
the floor.
To reduce the risk of electric shock, install and wire the
unit with the power to the PAC-SC51KUA power supply
unit turned off.
To avoid the risk of electric shock or malfunction of
the controller, install the controller in a
non-condensing environment.
Do not install this controller in a steamy place, such as a
bathroom or kitchen.
Do not install this controller where an acid or alkaline
solution or special chemical spray is used frequently
to avoid electric shock or malfunction.
Use specified wires with the proper current carrying
capacity to prevent current leakage, over-heating, or
fire.
Do not touch the PCB (Printed Circuit Board) either
with your hand or a tool.
Keep the PCB dust-free to prevent fire or malfunction.
To avoid the risk of electric shock or damage to the
controller, do not touch the touch panel or USB
storage device connector with wet hands.
To avoid the risk of electric shock or damage to the
controller, do not press the touch panel with sharp
objects.
Do not apply an AC voltage or a voltage higher than
32VDC to the M-NET or the Power (24VDC) terminal
blocks on the controller to avoid damage to these
parts or fire.
Use a security device such as a VPN router when
connecting the AG-150A to the Internet to prevent
unauthorized access.

* If the enclosed screw for attaching the installation plate cannot be used because the wall is too thick, obtain a longer M4 flathead
screw that matches the wall thickness.
* Besides the above parts, purchase a power supply unit (PAC-SC51KUA) that supplies power to the centralized controller (24VDC)
and the M-NET transmission line.
* If the AG-150A is connected to R410A compatible CITY MULTI outdoor unit (except the S series), it can be powered from the
outdoor unit. However, the power to the connected outdoor unit is turned off, the AG-150A cannot perform a schedule operation,
collect charge data, or perform energy save control.

Address setting method Address
Indoor unit
Set the indoor unit you want to make the main unit in the same group to the minimum
address, and sequentially set the indoor unit addresses in the same group.
1~50
Outdoor unit Minimum indoor unit address in same refrigerant system + No.50 unit. 51~100
Outdoor unit address in same refrigerant system + No.1 unit.
BC controller/OS controller
However, for Sub-BC controller, the minimum indoor unit address that connects the
52~100
local refrigerant piping should be + 50.
K control side remote controller Same address as indoor unit main unit 1~50
M-NET remote controller Set to the minimum indoor unit main address in the same group + 100. 101~200
MA remote controller Address setting is unnecessary. OA processing unit/LOSSNAY After setting all the indoor units, set an arbitrary address. 1~50
K transmission converter Minimum address of K control indoor unit + No.200 unit. 201~250
NOTE
* Apply following precautions when using the K transmission converter (model PAC-SC25KAA; discontinued) and controlling the
M-NET model and K control model with the same controller.
Refer to the K transmission converter (PAC-SC25KAA) installation manual for details.
1 Centralized controller address
Always set the controller address to “000”.
(Refer to section 8 Initial Setting .)
2 Centralized controller function selects
Always set the No.3 function selects of the controller to “ON”
(Refer to section 8 Initial Setting .)
3 Indoor unit address
Set all M-NET model indoor units from the No.1 unit, then set the K control model addresses.
Indoor unit No.1 unit ~M-NET indoor unit max. address> K control indoor unit minimum address ~50
4 K control model group No.
The minimum indoor address No. of that group becomes the group No. (Same for K control side local remote controller.)
