Bug present in the CBECC-Res 2019.1.2 release prevents the use of the latest CSE DHWSystem branch loss model (when EnableResearchMode is not activated).
This problem causes a less accurate branch loss calculation method to be used for all central DHW systems (proposed, standard & design rating runs).
This problem was fixed in SVN r1717 (trunk - 3/9/20), along with several other fixes and enhancements.
Since Scott posted, Scott fixed, and we apparently have no one who can verify this, I'm marking as verified.
