2. If addresses to indoor units are set in 2 or more
refrigerate lines manually by using the remote
control 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.)
