<p class=MsoNormal>This should be a quick question, but with eQuest you never
know.<br>
<br>
I am trying to set my ACH rates to 12, and in an parametric run, turn it down
to 6.&nbsp; This doesn't appear to be working because the entry line for the
ACH is minimum air to the zone.&nbsp; <br>
<br>
Is there a way to set the air flow to see the ACH minimum air as a maximum?<br
clear=all>
