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 nishing all the settings above, set the
address of the central control devices.
(For the setting of the central control address,
