Note 1)
When setting the line address from the wired remote controller, do not use address 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) is output.
Note 2)
When manual address has been set up from the wired remote controller, set up the following items for header unit of
each line if performing a central control over refrigerant lines.
• Using SW13 and 14 on the interface P.C. board of the header unit in each line, set up the line address for each line.
• Turn off SW30-2 on the interface P.C. boards of the header units of the lines connected to the identical central
control except a line with least address number.
(The terminal resistances of the cables in the central control system of indoor/outdoor are unified.)
• Connect the relay connector between [U1U2] and [U3U4] of the header unit for each refrigerant line.
• Then set up the central control address.
(For the central control address setup, refer to the Installation manual of the central control devices.)
