Auto Connect: Automatically establishes connections for linked devices in the drawing.
AutoBranch mode contains three options, and AutoBranch: NONE is selected by default. The NONE option will not allow existing circuits to be used for TTAP (branched) connections.
Conversely, selecting AutoBranch: TTAP will allow TTAP (branched) connections on the same circuit.
AutoBranch: Series will allow the branching of circuits, and will automatically add two circuits on the same wire path to accommodate the series as necessary.
Manual Connection Mode is also available, and will not automatically add circuit information for the current appliance. As a result, circuit information will NOT be updated for existing appliances.
Disabling the Automatic circuit connection
button, which will appear as
when disabled, changes the circuit connection mode to Manual.
