CHECK HVAC DUCT SYSTEM WARNING

[malihinv]

Hello everyone
I checked a supply system, called Sistem refulare 1, and found the following message:
,,Elements in Sistem refulare 1 are not connected in a single physical network due to one or both of the following:
- There are disconnections in the system's physical network.
- Elements in the system are connected to more than one physical network.''

What steps should I follow to solve the problem?
Thank you for help

Have you capped off the duct end?

Also is the reducer properly connected?

Check that the system classification (Supply, Exhaust or Return) of the air terminals matches that of the connector on the fan/VAV unit.

My guess is the connectors on the various families you are using are set to specific systems. so when you change the name it is getting confused. 

Another options could be that the elements were already connected as a System (equipment, air terminals, etc), then when you added the duct, set to Sistem refulare 1, it is trying to make another system.
