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 error) 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 outdoor unit of each line as below.
• Set a system address for the 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 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 (CN10) between the [U1, U2] and [U3, U4] terminals on the interface P.C. board to
CN02 in all the outdoor units to which the central control is connected.
• 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.)
