<p class="MsoNormal">DCV - For min OA - make sure you have some non-zero value - I think that triggers the economizer. If you are using the min OA schedule - make sure it is either .001 or -999 for economizer to work. Let me know if helps.<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">I have a DCV measure that shows an increase in cooling. My thought is that DCV is taking precedence over the economizer. Is there a way to force eQuest to have economizer priority

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">The other issue is in the Heat Recovery. It also shows an increased cooling load for the building. I tried setting it on an ERV Schedule and limiting it to the heating season. I
tried playing with the different controls. I know it’s not due to the increase in fan energy needed since the majority of units already have ERVs, but the efficiencies are better than code (and I also tried messing with the fan energy). Someone on the bldg-sim
list even suggested controlling the ERV with Exhaust DT and increasing the delta-T to 20F.
