ADDRESS SETUP
REQUIREMENT
• When a group control is performed over the
multiple refrigerant lines, be sure to turn on the
power supplies of all the indoor units connected in
a group in the time of address setup.
• If turning on the power for each refrigerant line to
set up address, a header indoor unit is set for
each line. Therefore, an alarm code "L03"
(Duplicated indoor header units) is output in
operation after address setup. In this case,
change the group address from the wired remote
controller so that only one header unit is set up.
Address setup procedure 2

Using SW13 and 14 on the interface P.C. board of the header
unit in each system, set up the system address for each system.

Note) Be careful not to duplicate with other refrigerant line or other
system address.
