[Equest-users] DOAS Dummy Warnings - no problem?

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,
