How can i tell if the system is using a lower OA CFM during the less occupied times? <br><br><div class="gmail_quote">On Wed, Apr 28, 2010 at 10:43 AM, Bishop, Bill <span dir="ltr"><<a href="mailto:wbishop@pathfinder-ea.com">wbishop@pathfinder-ea.com</a>></span> wrote:<br>

<p class="MsoNormal"><font color="navy" face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial; color: navy;">I recently modeled DCV successfully for
the first time. (I showed savings anyway.) You need to enter zone-level OA as OA-FLOW/PER
and/or OA-FLOW/AREA. The OA flow/per (person) is what will get you the savings,
based on your occupancy schedule(s). I also created a MIN-AIR-SCH, coinciding
with the fan schedule, set to zero when fan is off and -999 when fan is on.</span></font></p>

<p class="MsoNormal"><font face="Times New Roman" size="3"><span style="font-size: 12pt;">I am having some trouble with setting up DCV in my model. if i
select DCV in Zone Sensors for the Min OA Control Method and a min outside Air
Ratio, do i need any Zone level OA inputs?<br>
Any help or insight as to what inputs are necessary for DCV would be great!<br clear="all">
