Notes (1) Don’t use the auto mode on any indoor unit other than those connected to the simultaneous heating & cooling 3-pipe system or single PAC. (2) Do not set the set point at 0.5˚C intervals in case this product is used with RCD type wired remote controller. It would cause malfunction of the wired remote controller. Please make sure to set at 1˚C intervals. (3) This function can be applied to the indoor units, which are the model KXE4 or later, SC-ADN-E or later and to the remote controller, which is the model

RC-E1 or later. (For models earlier than the above-mentioned, the function becomes invalid because the indoor unit and remote controller cannot receive

the instruction even though the setting can be displayed.) Since setting is overwritten in SL2NA-E even if setting is done from the remote controller, set using SL2NA-E. (4) This function can be applied to the indoor units, which are the model KXE6D or later, SC-ADNA-E or later. For the previous indoor units, it is not possible to set the 4th mode but other setting is possible as before. 4th fan speed setting is “impossible” before shipment, so changing to “possible” is needed for 4th fan speed setting from this Central control. 4th fan mode of indoor units operating at 4th fan mode can be displayed on SC-SL2NA-E whose 4th fan mode setting is “impossible”. (SW7 changes “possible” or “impossible” for 4th fan mode setting from SC-SL2NA-E.)

Sets all air-conditioners connected to this unit at “Stop” and “Center” with an external emergency signal. As the emergency signal is cancelled, the center/remote setting is returned to original state but all units stay “Stopped”

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.

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. SC-

SL2N-E does not perform timer the power restoration processing upon restoration of the power supply.

Wiring Outline

Wiring specifications

(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

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.

When performing the continued installation of multiple controllers, be sure to obtain the distance between units and service

space as shown in the ﬁgure.
