Safety precautions to be observed without fail
* Hazards and levels of danger that can occur due to incorrect handling are classified by the following symbols.
Warning
Incorrect handling can result in death, serious injury, etc.
Cautions
Incorrect handling can result in injury or damage to the building or its contents.
* After reading this manual, keep in a handy place. When removing or repairing the unit, give this manual to the installer. When the user
changes, also give to the new user.
Warning
Ask your dealer or technical representative to install.
If incorrect installation is done by a customer, it may cause
an electric shock, fire, etc.
Securely install in a place which can withstand the
weight of the controller.
If it is not enough, the unit may fall and cause an injury.
Securely connect the wiring using the specified cables
and fix them so that the stress from the cables is not
applied to the terminal connection sections.
If connection or fixing is not sure, it may cause heat generation, a fire, etc.
Never modify or repair by yourself.
If the controller is modified or a repair is not correct, it may
cause an electric shock, fire, etc.
Consult your dealer if repairs are necessary.
Securely install the controller according to the installation manual.
If installation is not correct, it may cause an electric shock,
fire, etc.
The electric work should be perform by authorized personal according to the installation manual.
Any lack of electric circuit or any deficiency caused by installation may result in an electric shock or fire.
Do not move and re-install the unit by yourself.
If installation is not correct, it may cause an electric shock,
fire, etc.
Ask your dealer or technical representative.
Cautions
Do not install the controller in a place where flammable
gas could leak.
If gas leaks and collects around the unit, it may cause a fire
or explosion.
Do not install this controller in a place where steam is
generated such as bathroom, kitchen, etc.
Avoid placing where water condenses on the walls. It may
cause an electric shock or malfunction.
Do not use this controller in an abnormal environment.
If the controller is used in a place where there is much oil
(including machine oil), steam or sulfide gas, the performance of the controller may deteriorate or parts may be damaged.
Do not install this controller in a place where an acid or
alkaline solution, special spray, etc. is used frequently.
It may cause an electric shock or malfunction.
Perform wiring so the tension is not applied.
If tension is applied, it may cause disconnection, heat generation or a fire.
Seal the wire lead-in port with putty to prevent the entry
of dew, water, insects, etc.
It may cause an electric or malfunction.
Do not wash this controller with water.
It may cause an electric shock or malfunction.
Do not install this controller in a place where the ambient temperature exceeds 40°C (104°F) or drops below
0°C (32°F), also do not install in a place where it is exposed to direct sunlight.
It may cause a deformation or malfunction.
Use specified wires corresponding to the current capacity for wiring.
Otherwise it may cause power leakage, heat generation or
fire.
Do not touch the PCB (Printed Circuit Board) with your
hand or a tool. Also do not get dirt on the PCB.
It may cause a fire or malfunction.
Do not touch the switches with wet hands.
It may cause an electric shock or malfunction.
Do not press the switches with sharp objects.
It may cause an electric shock or malfunction.
Do not connect an AC power source to the M-NET and
Power (DC12V) terminal blocks of this device.
It may cause a breakdown or fire.

Set the indoor unit you want to make the master unit in the same group to the minimum address, and sequentially set the indoor unit addresses in the same group.
Min.indoor unit address in same refrigerant system + No.50 unit.
Outdoor unit address in same refrigerant system + No.1 unit.
However, for Sub-BC controller, minimum indoor unit address that connects the local refrigerant piping + 50.
Same address as indoor unit master unit
Set to the minimum indoor unit master address in the same group + 100.
Address setting is unnecessary.
After setting all the indoor units, set an arbitrary address.
Min.address of K control indoor unit + No.200 unit.

NOTE
* The following precautions will apply when using the K transmission converter (model:PAC-SC25KAA) and controlling the M-NET
model and K control model with the same controller.
Refer to the K transmission converter installation manual for details.
1 Central controller address
Always set the controller address to “000”.
(Refer to section 6 Initial setting .)
2 Central controller function selects
Always set the No.3 function selects of the controller to “ON”
(Refer to section 6 Initial setting .)
3 Indoor unit address
Set all M-NET model indoor units from the No.1 unit, and then set the K control model addresses.
Indoor unit No.1 unit ~M-NET indoor unit max. address->K control indoor unit min. address ~50
4 K control model group No.
The min.indoor address No. of that group becomes the group No. (Same for K control side local remote controller.)

2. Installation method
1 Secure the space shown on the right when installing the electric box.
2 When installing the controller on the electric box, the controller will be shifted by 1mm (1/32 in) to the left as shown above.
NOTE
* When installing two controllers horizontally in parallel, secure a clearance of 30mm (1-3/16 in) or more between the products.
When installing vertically with the same clearance, removing of the cover will be difficult.
* When connecting a LAN and RS-232C, a space for the connector and wiring is required. Provide this space between this unit
and the rear of the electric box.
It varies depending on the specifications of the LAN cable and RS-232C cable that is procured, but the LAN connector may
protrude approximately 20mm (25/32 in) and the RS-232C connector may protrude approximately 40mm (1-9/16 in) from the
bottom of the unit cabinet. Provide a cable with the smallest possible connector to secure space.

3. Confirm the run state (indoor unit outlet air temperature, cool air, confirmation, etc.) during the test run.
4. When each unit has been confirmed, stop the unit with the controller or local remote controller. Even if the units are not stopped, the
test run will stop automatically after approx. 2 hours.
* Refer to the installation manual for the connected indoor unit for details on the test run method.

Example for system configuration
1. To control a K control model
* Set G-50A address to “000” When a K transmission converter is connected. Always set to the master system controller when the address is
“000”.
* When using a group setting for the K control model, set only the indoor
unit that belongs to that group.
* Set the min.indoor unit address in the group for the K control model group
No.
* Set the master system controller function select No.4 to “OFF” (operation
prohibit transmission valid) when the K transmission controller is connected.
