4.2.3.8 n5 Indoor Unit Engineering SN Offset
Introduction:
When different refrigerating systems are controlled in a centralized manner (by remote monitoring or
a centralized controller), this function sets the engineering numbers of indoor units and avoids their
conflict among different systems, and therefore must be set.
Set this function only in the master system, whose centralized control address SA2 is "0000×". For
details, see the settings in section "Address DIP Switch for Centralized Control (SA2_Addr-CC)".
Setting steps:
Step 1:
Enter n5 indoor unit engineering SN offset, and ensure that the master unit displays as
follows:
