I saw your question on the warnings from your DOAS model and didn't see
any replies. I have some of those same warnings.

**WARNING**********************************************************************
EL1 Sys1 (PVVT) (G.SW1) has a MIN-AIR-SCH, OA-CONTROL
other than FIXED and/or a MIN-OA-METHOD other than
FRACTION-OF-DESIGN
along with having a specified OA-FROM-SYSTEM. This may
cause incorrect
OA load/flow calculation for its OA-FROM-SYSTEM.

Shows up for each zone the DOAS is supplying and so does:

**WARNING**********************************************************************
SYSTEM EL1 Sys1 (PVVT) (T.C12) has zero outside
air for design calculations

the second one seems normal since I put 0 cfm OA in the DD wiz before I
went to detailed edit mode, but I'm not sure about the first one.

Hope your model turned out well, for both of our sakes.

Thanks,
