<div>It sounds like the heated air is not being allowed to go where there is a call for conditioning, have you checked your system reports too? it might have to do with your system & temp scheduling. Can you send your .pd2 & .inp file both so that we can open your file in eQuest?</div>

<div>thanks,</div>

Use Reverse Action if you want to allow the supply flow in heating mode to rise above the minimum flow ratio, otherwise use Proportional. Also try reducing the cool control range from 4 deg to 1 deg.</span></p>

<p class="MsoNormal">All,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I am modeling a two-story elementary school with a VRV / DOAS system in one area (classrooms, admin.), and a VAV system in another (gym, cafeteria, food prep.). The unmet heating hours are currently around 750, and I am at my wit’s end to reduce them further. I have incorporated suggestions such as increasing the throttling range (currently at 6, helped a little bit) and sizing ratio (currently at 1.15, although increasing to 2.00 did not help much). As I have also tried my best to model the VRV / DOAS system, I’m still not sure if it is correct… I’ve just picked up what I could from the users archives.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Does anyone have suggestions for reducing the unmet heating hours that I may not be aware of? I have attached the .inp file. Can anyone see glaring mistakes in the model?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Thanks,</p>
