<div><font face="tahoma,sans-serif">Kamel, Bill,</font></div><div><font face="tahoma,sans-serif">Thanks for the reply. I changed the OA cfm for all the zones to 0. Now in the SV-A report the zone OA is showing as zero but the system OA ratio is 0.2 and the custom hourly report variables (ratio of outside air to supply flow - Var 39, and the minimum OA damper position - Var 80) are still varying from 0.21 to 0.56. Not sure from where eQuest is getting 0.2 value or these other values in the hourly report.</font></div>

<div><font face="trebuchet ms,sans-serif">I am trying to simulate zero outside
air. I set the min OA on the systems tab to zero, economizer to fixed fraction,
there are no OA numbers at the zone level. I would assume this will give me zero

- Var 39, and the minimum OA damper position - Var 80) they vary from 0.21
