setting is returned to original state but all units stay “Stopped”
Power restoration control
Allows changing the power restoration process setting.
Program timer preferred: When SW1 and SW2 are turned ON. RUN/STOP and
setting temperature returns to the program timer just before the time of power
restoration on the day when the power supply is restored, or other states (operation mode, etc) return automatically with the priority given to the states before
the power failure (See ).
When no program timer is set before the power restoration on the day of power
restoration, it is restored with the priority given to the states before the power
failure (See ).
State before power failure preferred: When SW1 is turned ON and SW2 is
turned OFF. Each indoor unit returns automatically to the state before the power failure.
Any indoor unit running before the power failure starts its operation.
No power restoration processing: When SW1 and SW2 are turned OFF. SCSL2N-E does not perform timer the power restoration processing upon restoration of the power supply.
Power failure compensation
The group setting, individual setting, program timer setting, holiday setting, external timer setting, demand setting and operating condition (RUN/STOP, operating
mode, temperature setting, Center/Remote, remote controller permission/prohibition and airflow volume) are retained regardless of the length of power failure,
The clock time is compensated if the power interruption is not longer than 48
hours. If the current time is not displayed after the power restoration following a
power interruption exceeding 48 hours, set again the current time. Since the clock
time is not retained at the power restoration after a power interruption exceeding
48 hours, the power restoration control in Item No. (9) (a) does not operate.

Wiring specifications
Wiring Outline
(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
Service space

’10 • SC-T-154
(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.
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.
(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.
When performing the continued installation of multiple controllers, be sure to obtain the distance between units and service
space as shown in the figure.

(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 second, that can
initialize the setting contents.
c 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.
