ADDRESS SETUP
Note 1)
When setting the line address from the wired remote controller, do not use addresses 29 and 30.
The address 29 and 30 cannot be set up in the outdoor unit. Therefore if they are incorrectly set up, a check code
[E04] (Indoor/outdoor communication circuit error) will be displayed.
Note 2)
When an address has been manually setup from the wired remote controller and you wish to set up a central control
over the refrigeration system and setup the outdoor unit for each system using the following steps.
• Using SW13 and 14 on the interface P.C. board of the header unit in each system, set up the line address for
each system.
• Turn off SW30-2 on all other interface P.C. boards on the header outdoor units that are connected to the same
central control, not including the system with the least number of address lines.
(The terminator resistor of the cables in the central control system of indoor/outdoor are unified.)
• Connect the relay connector between [U1U2] and [U3U4] of the header outdoor unit for each refrigerant system.
• Then set up the central control address.
(For the central control address setup, refer to the Installation manual of the central control devices.)
