Manual Topology Document for Auto Topo
Yes, the manual topology document can also be used in case of auto topology that is when we connect the 2
DC indoor units with V6/VX outdoor units. Of course, we can simply use the auto topology mode for this combination and
we don't need to use the manual topology here and the controller can automatically detect the indoor units by itself. But,
there are a few advantages in case we use the manual topology document here.
We can write the the name for the devices in the topology file according to our convenience as it is slightly easier to write
the names in the Excel file rather than the software. But in case, you want to use this option, you should make sure that
along with the name, all the other columns in the manual topology document are also filled properly.

Reason 1: If the columns, such as "bus", "system", "address", "unitModel",
"fan", "eHeat" and "deviceType" are filled correctly, the system will report
this error for non-digital input.
Reason 2: Negative numbers exist in Manual Topology document.
Reason 3: In case files are damaged or USB drive was pulled out when the
system was reading files, an error will be reported when reading file
streams.

The unit model is not within IDU 0-12 and ODU 0-2.
IDU address is not within 0-63.
ODU address is not within 0-31.
Reason 1: Equipment names overlap.
Reason 2: More than two equipment overlap in the data.
Standard for data overlap is (the same bus, the same address and the same
equipment type).
Only parse ".csv" files. If the file is not this, the system will report error.
In case the USB drive is not inserted or USB drive does not have enough
space, the system will report this error.
Reason 1: If other files are changed to ".csv" format, errors occur when
parsing.
Reason 2: Unable to parse if importing column names are beyond the notes
on Manual topology document. This error will be reported in this case.
