When I set OA cfm to 0 and system min OA to 0, I do get 0 for
variable 39 & 0 for OA in the SV-A report. What system type?<br>
<br>
Perhaps best if you send .pd2 and .inp to list to have a look.<div><br>

<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>
