Indoor unit line address manual setting / change
[For 29 or less refrigeration systems (when they are used together with the SMMS series, the number
of refrigeration systems 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 controller.
NOTE
• For changing / setting line addresses using the wired remote controller, refer to
“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, DI series are operated under central control together with those of the SMMS series, set line
addresses different from those of the SMMS series.)

Indoor unit line address manual setting / change
[For 30 or more refrigeration systems (when they are used together with the SMMS series, the number
of refrigeration systems of the SMMS series is included.)]
The line address change / setting procedure for up to the 29th refrigeration system is the same as that
described in step 1 on the previous page.
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 controller.
Also change the indoor addresses so that they are not duplicated.
NOTE
• For changing / setting line addresses using the wired remote controller, refer to
“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, DI series are operated under central control together with those of the SMMS series, set line
addresses different from those of the SMMS series.)
