① Outdoor unit address setting
Set as follows before you turn on power.
Make sure that the Outdoor Unit No. switch is set to 49 (factory setting)
② Indoor unit address setting
Set as follows before you turn on power.
Make sure that the Indoor Unit No. switch is set to 000 [in the case of previous SL: 49] (factory setting)
Make sure that the Outdoor Unit No. switch is set to 49 (factory setting)
③ Turn on power in order from the outdoor unit to indoor units. Give a one-minute or longer interval for them. Unlike the procedure set out in (2) below, you need not change settings from
the 7-segment display panel.
④ Make sure that the number of indoor units indicated on the 7-segment display panel agrees with the number of the indoor units that are actually connected to the refrigerant system.
(2) In the case of a multiple refrigerant systems installation (Applicable to new SL only. In the case of previous SL, set addresses with some other method.)
(This option is available when the interconnection wiring among refrigerant systems is on the outdoor side and new SL is chosen as the communication protocol.)
Address setting procedure (perform these steps for each outdoor unit)
[STEP1] (Items set before turning on power)
① Outdoor unit address setting
Set as follows before you turn on power.
Set the Outdoor Unit No. switch to a number 00 - 31. Set a unique number by avoiding the numbers assigned to other outdoor units on the network.
② Indoor unit address setting
Set as follows before you turn on power.
Make sure that the Indoor Unit No. switch is set to 000 (factory setting)
Make sure that the Outdoor Unit No. switch is set to 49 (factory setting)
③ Isolate the present refrigerant system from the network.
Disengage the network connectors (white 2P) of the outdoor units. (Turning on power without isolating each refrigerant system will result in erroneous address setting.)
[STEP2] (Power on and automatic address setting)
④ Turn on power to the outdoor unit
Turn on power in order from the outdoor unit to indoor units. Give a one-minute or longer interval for them.
⑤ Select and enter “1” in P31 on the 7-segment display panel of each outdoor unit to input “Automatic address start.”
⑥ Input a starting address and the number of connected indoor units.
Input a starting address in P32 on the 7-segment display panel of each outdoor unit.
⑦ When a starting address is entered, the display indication will switch back to the “Number of Connected Indoor Units Input” screen.
Input the number of connected indoor units from the 7-segment display panel of each outdoor unit. Please input the number of connected indoor units for each outdoor unit. (You can
input it from P33 on the 7-segment display panel.)When the number of connected indoor units is entered, the 7-segment display panel indication will switch to “AUX” and start flickering.
[STEP3] (Automatic address setting completion check)
⑧ Indoor unit address determination
When the indoor unit addresses are all set, the 7-segment display panel indication will switch to “AUE” and start flickering.
If an error is detected in this process, the display will show “A○○.”
Check the 7-segment display panel of each outdoor unit.
Depending on the number of connected indoor units, it may take about 30 minutes before the indoor unit addresses are all set.
[STEP4] (Network definition setting)
⑨ Network connection
When you have confirmed an “AUE” indication on the display of each outdoor unit, engage the network connectors again.
⑩ Network polarity setting
After you have made sure that the network connectors are engaged, select and enter “1” in P34 on the 7-segment display panel ofany outdoor unit (on only 1 unit) to specify
network polarity.
⑪ Network setting completion check
When the network is defined, “End” will appear on the 7-segment display panel. An “End” indication will go off, when some operation is made from the 7-segment display panel or
3 minutes after.

Summary of address setting methods (figures in [ ] should be used with previous SL)
(*1) Do not set numbers other than those shown in the table, or an error may be generated.
Note: When units supporting new SL are added to a network using previous SL such as one involving FD○A△△KXE4 series units, choose previous SL for
the communication
protocol and set addresses manually.
●
An outdoor unit No., which is used to identify which outdoor unit and indoor units are connected in a refrigerant system, is set on outdoor unit PCB and indoor unit PCB.
Give the same outdoor unit No. to all outdoor unit and indoor units connected in same refrigerant system.
●
An indoor unit No. is used to identify individual indoor units. Assign a unique number that is not assigned to any other indoor units on the network.
When plural refrigerant systems are linked with signal lines
(e.g., to implement central control)
Incorrect cable connection

Units supporting new SL Units NOT supporting new SL
Unless stated otherwise, the following procedures apply, when new SL is chosen for the communication protocol.
When previous SL is chosen, use figures shown in [ ] in carrying out these procedures.
Manual address setting Generally applicable to new SL/previous SL, use figures in [ ] with previous SL.
・Within a refrigerant system, indoor units are assigned addresses in the order they are recognized by the outdoor unit. Therefore, they are not necessarily assigned
addresses in order from the nearest to the outdoor unit first as depicted in drawings above.
・Make sure that power has been turned on to all indoor units.
・When addresses are set, you can have the registered indoor unit address No.’s and the outdoor unit address No. displayed on the remote control unit by pressing its
Inspection switch.
・Automatic address setting can be used for an installation in which prulal indoor units are controlled from one remote control unit.
・Once they are registered, addresses are stored in microcomputers, even if power is turned off.
・If you want to change an address after automatic address setting, you can change it from the remote control unit with its “Address Change” function or by means of
manual setting. Set a unique address by avoiding the address assigned to other indoor unit on the network when the address is changed.
・Do not turn on power to central control equipment until automatic address setting is completed.
・When addresses are set, be sure to perform a test run and ensure that you can operate all indoor and outdoor units normally. Also check the addresses assigned to the
indoor units.

This control system controls the controllers of more than one air conditioner's outdoor unit, indoor unit and remote control unit through communication control, using the
microcomputers built in the respective controllers. Address setting needs to be done for both outdoor and indoor units. Turn on power in the order of the outdoor units and
then the indoor units.
Use 1 minute as the rule of thumb for an interval between them.
The communication protocol can be choosen from following two types. One of them is the conventional Superlink (hereinafter previous SL) and the other is the new
SuperlinkⅡ (hereinafter new SL). These two communication protocols have their advantages and restrictions as summarized in a table in “6. ELECTRICAL WIRING
WORK” so please choose a desirable one meeting your installation conditions such as connected indoor units and centralized controller.
When signal cables are connected into a network invol
ving outdoor units, indoor units or centralized control equipment that do not support new SL, please select
communications in the previous SL mode, even if the refrigerant system is separated from theirs.
When communication is established after setting addresses, check the communication protocol with the 7-segment display panel of the outdoor unit.
