Note 1)
When setting the line address from the remote controller, do not use Address 29 and 30.
As they are addresses which cannot be set to the outdoor unit, if they are set, the check code [E04] (Indoor/Outdoor
communication circuit error) is issued.
Note 2)
When an address was manually set from the remote controller and the central control over the refrigerant lines is
carried out, perform the following setting for the Master unit of each line.
• Set the line address for every line using SW13 and 14 on the interface P.C. board of the center unit in each line.
• Except the least line address No., turn off SW30-2 on the interface P.C. board of the Master units in the lines
connected to the identical central control.
(Draw the terminal resistances of indoor/outdoor and central control line wirings together.)
• For each refrigerant line, connect the relay connector between Master unit [U1U2] and [U3U4] terminals.
• After then set the central control address.
(For setting of the central control address, refer to the Installation manual for the central control equipment.)
