Notes (1) In case of previous SL, since SC‑SL3N is for connection of 3 Super Link systems, one unit of SC‑SL2N‑E can be connected to
each system.
(2) Number of units in combination as shown above is applicable to when the indoor units being controlled by each central control are
not duplicated. When controlling the same indoor units with a plural number of central controls, it may affect the allowable
number of indoor units for connection. For further details, please consult your dealr.

Definitions of new and previous Super Links (new and previous SL)
New Super Link (new SL): All units connected to the network are models compatible new Super Link (KXE6 or
later models. Central controll and I/F are “N” or later models.), and the SL setting is
unchanged from the shipment (“New” or “Auto”).
Previous Super Link (previous SL): Units that do not meet the conditions of new SL. When the equipment connected to
the network include even one unit of model earlier than KXE4 or not with new SL.
Setting of Note (3) is required.

(5) Installation work
Please install the central control after turning off the power for fear of electric shock. Please arrange or protect the wiring so that
excessive force is not applied to the electrical wires.
Be careful that you do not damage the PCBs when using a screwdriver and other tools. The PCBs can be damaged by static
electricity, and so be sure to discharge any static electricity accumulated on your body before starting the work. (Static electricity
can be discharged by touching the control board and other grounded parts.)
(a) Installation Place
Please install in an indoor location that is not exposed to electromagnetic waves, water, dust, or other foreign substances. The
operating temperature range of this product is from 0˚C to 40˚C.
Install in a location where the ambient temperature remains within the operating temperature range. However, if the operating
temperature range is exceeded, be sure to implement corrective measures such as installation of a cooling fan. Be aware that
continued usage of this central control outside the operating temperature range can result in operation problems.

-
(b) Space required for installation
The dotted lines show the installation opening section for installation on the control board (the dimensions are only an example).
1) In case of installing on the control board
Please be sure to lock the control board to protect persons from electric shock.Avoid usage of heat-retaining materials and
heat-insulating materials because these can result in heat buildup and adversely affect the operation of the central control.
2) In case of embedding in a wall
Please check that the sufficient space is available in the wall.If the temperature inside the wall exceeds 40°C, install the
central control on the control board.
Caution
Please do not install devices that can cause the ambient temperature to rise in the same control board. Also, do not install
multiple controllers in the same control board. These can cause heat to build up and result in false operation. If multiple
central control must be installed in the same control board, take corrective measures to ensure that the temperature in the
control board does not rise above 40°C such as by installing cooling fans.

(9) Installation work
Please install the central control after turning off the power for fear of electric shock.
Please arrange or protect the wiring so that excessive force is not applied to the electrical wires.
Control PCBs (printed circuit boards) are mounted to both the top and bottom cases.
Be careful that you do not damage the PCBs when using a screwdriver and other tools.
The PCBs can be damaged by static electricity, and so be sure to discharge any static electricity accumulated on your body before
starting the work.
(a) Installation place
Please install in an indoor location that is not exposed to electromagnetic waves, water, dust, or other foreign substances.
The operating temperature range of this product is from 0˚C to 40˚C.
Install in a location where the ambient temperature remains within the operating temperature range.
However, if the operating temperature range is exceeded, be sure to implement corrective measures such as installation of a
cooling fan.
Be aware that continued usage of this of this central control outside the operating temperature range can result in operation
problems.
(b) Space required for installation

(c) In case of installing on the control board
Please be sure to lock the control board to protect persons
from the electric shock.
Avoid usage of heat-retaining materials and heat-insulating
materials because these can result in heat buildup and
adversely affect the operation of the central control.
(d) In case of embedding in a wall
Please check that there is sufficient space inside the wall.
If the temperature inside the wall exceeds 40˚C, install the
central control on the control board.
Caution
Please do not install devices that can cause the ambient
temperature to rise in the same control board. Also, do
not install multiple controllers in the same control board.
These can cause heat to build up and result in false
operation. If multiple central control must be installed in
the same control board, take corrective measures to ensure
that the temperature in the control board does not rise
above 40˚C such as by installing cooling fans.

(11) Setting the control target units
Make the settings for the units to be controlled by the central control.
For the setting procedure, see the user’s manual attached to the central contrl.
At shipping, none of the units are set as target units for control, and so the units to be controlled by this
central control must be set as control target units.
Three types of settings are available.
① Units are selected as control targets for central control and controlled as a group →Group setting
② Units are selected as control targets for central control but not grouped →Individual setting
③ Units are not selected as control targets for central control →Not target units for control
(or units will be controlled by another central control)
Be sure to set the current time. This is needed for the program settings and error history display.
Turn on the power and press the three buttons (MENU, RESET, GROUP No. 10) at once more than five minutes, that can
initialize the setting contents.
● Group control when using multiple units
This central control can control up to 64 target units (up to 48 units when using the previous Super Link setting). Multiple
central controls must be installed to control 65 or more air conditioner units.
When connecting multiple central controls on a single network, any group settings can be made for each central control.

Definitions of new and previous Super Links (new and previous SL)
New Super Link (new SL): All units connected to the network are models compatible with New Super Link
(KXE6 model or later models. Central controller and I/F are from “N” models.) and
SL setting is unchanged from shipment (“New” or “AUTO”).
Previous Super Link (previous SL): Units do not meet the conditions of New SL. When even a single unit connected to
the network is an earlier model than KXE4 or the connected model is not compatible
with new SL.
Use the “Function setting” screen of main unit to set new or previous Super Link (new or previous SL).
When the connecting network consists of previous Super Link, it is necessary to change the selection.
(3) Control selection setting
It is possible to change the setting as follows by setting on the “Function Setting”

(6) Outline drawing
(7) Installation work
Please install the central control after turning off the power for fear of electric shock.
Please arrange or protect the wiring so that excessive force is not applied to the electrical wires.
(a) Installation place
Please install in an indoor location that is not exposed to electromagnetic waves, water, dust, or other foreign substances. The
operating temperature range of this product is from 0˚C to 40˚C.
Install in a location where the ambient temperature remains within the operating temperature range. However, if the operating
temperature range is exceeded, be sure to implement corrective measures such as installation of a cooling fan. Be aware that
continued usage of this central control outside the operating temperature range can result in operation problems.
(b) Space required for installation
Please choose one of two ways.
1) In case of installing on the control board
• Please use the control board of the size of 300mm
x 400mm x 120mm or larger.
• Please be sure to lock the control board to protect
persons from the electric shock. Avoid usage of heat-
retaining materials and heat-insulating materials
because these can result in heat buildup and adversely
affect the operation of the central control.
Caution
Please do not install devices that can cause the
ambient temperature to risea in the same control
board. Also, do not install multiple controllers in
the same control board. These can cause heat to
build up and result in false operation. If multiple
central control must be installed in the same
control board, take corrective measures to ensure
that the temperature in the control board does not
rise above 40˚C such as by installing cooling fans.

2) In case of embedding in a wall
Please be sure to use the special box, SLA3R-BX (sold
separately) to secure sufficient air circulation space. If
the box is unused, the central control will not work
properly because of heat buildup inside the box.
Please be sure to use for protecting persons from the
electric shock.
Please check that the sufficient space is available in
the wall.
When the inside of the wall is divided and have a cavity,
please create space more than 0.08m3. Refer to the table
below.
If there is no partition on the left, right, top and bottom
of the central control, please create a space that is
105mm or deeper.
When you cannot create the sufficient space or
thickness of the wall is above 15mm, please install the
central control on the control board.
