[Equest-users] Bad building component

[Pasha Korber]

Ethan-  Thank you!  I worked only in eQuest interface to set it up-- buy
your reference of the wrong control zone might be likely.  I'm doing a VRF
system in DOE 2.3, and I don't have a good step by step reference to make
sure I have set it up correctly.  I;ve been able to get through this
initial error that I first referenced, but now I have some errors in
running the file that I think is specific to the VRF units.  The error I'm
able to "see" is a convergence error-  I've never gotten anything like this
before, and it appears differently in the SIM file than we are used to
seeing.  I am grateful for any insight the rest of you have.
