of the SMMS series is included.)]
Since all line addresses are set to
“1”
except for group control by the automatic address setup function after system power-on,
change the line addresses for each refrigeration system using the wired remote control.

“Manual address setup procedure”
.
• Line addresses must be unique for each refrigeration system. Set a line address that is different from any of line addresses
of other refrigeration systems.
(If indoor units of the SDI series are operated under central control together with those of the SMMS series, set line
addresses different from those of the SMMS series.)
