eQuest supply cfm and OA

Hello,

I am working on a building comprising three main zones. One of these zones
has a 100% OA requirement. I would like for eQuest to auto size the supply
cfm for all zones, thus in the wizard I do not specify any flowrate or OA%.
Once in the detailed mode, under the "Outdoor Air" tab and the "Outside Air
and Economizer" screen, I set the minimum outside air ratio to 1.0. After
running the simulation and checking the SV-A report, it says that the OA%
for this zone for the simulation was actually 3%, not the 100% this zone
requires. Can anyone tell me how to force eQuest to 100% OA? I looked at
the help for the outside air ratio and it stated that it was for winter
heating periods. Is there a work around for this? I have attached the .inp
and .pd2 files for this project.

Thank you for your assistance.

Marcus,

You need to remove any specification of OA flow at the zone level. In eQUEST, zonal values often/always(?) trump system values. In order to remove the value and leave the cell blank, right click and hit "restore default".
