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
nd
Generation
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.
