Address No. setting
Set SW1 through 4 and SW5-2 provided on the PCB and SW1 & 2 provided on the outdoor unit PCB as shown in the drawings below.

Summary of address setting methods (figures in [ ] should be used with previous SL)
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.
Since the models FDT224 and 280 have 2 PCBs per unit, set different indoor unit No. and SW on each PCB.
●
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.

Address setting methods
The following address setting methods can be used. The procedure for automatic address setting is different from the conventional one.
Please use the automatic address setting function after reading this manual carefully.
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 chosen from following two types. One of them is the conventional communication protocol (previous SL) and the other is the new communication protocol (new
SL). These two communication protocols have their own features and restrictions as shown by Table 6-3. Select them according the indoor units and the centralized control to be connected.
When signal cables are connected into a network involving 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.
※
1 Do not connect the signal line between outdoor units to A1 and B1. This may interrupt proper address setting. (Case 3)
Do not connect the signal line between indoor unit and outdoor unit to A2 and B2. This may interrupt proper address setting. (Case 4)
※
2 In Case 2, automatic address setting is not available. Set addresses manually.
