NOTE
1. Do not use address numbers 29 or 30 when setting system addresses using the remote
controller.
These 2 address numbers cannot be used on outdoor units and the CODE No. [E04] (Indoor
/ outdoor communication trouble) will appear if they are mistakenly used.
2. If you set addresses to indoor units in 2 or more refrigerate lines manually using the remote
controller and will control them centrally, set the header outdoor unit of each line as below.
• Set a system address for the header outdoor unit of each line with SW13 and 14 of their interface P.C.
boards.
• Turn off DIP switch 2 of SW30 on the interface P.C. boards of all the header outdoor units connected to
the same central control, except the unit that has the lowest address. (For unifying the termination of the
wiring for the central control of indoor and outdoor units)
• Connect the relay connectors between the [U1, U2] and [U3, U4] terminals on the header outdoor unit of
each refrigerate line.
• After finishing all the settings above, set the address of the central control devices. (For the setting of the
central control address, refer to the installation manuals of the central control devices.)
