<div dir="ltr"><div>Michael,<br><br></div><div>First, you're under 300 hours so indeed it's a minor problem.<br><br></div><div>I've only looked at your model very briefly but:<br><ul><li>HW loop operation is set to "SNAP" at OA of 60°F. This is causing some minor underheating in shoulder season.<br></li></ul><ul><li>You have local exhaust fan with makeup = infiltration. Basically equest ignores this added infiltration during the sizing, so you have to trick it to take it into account by having a different schedule for sizing (heating AND cooling design days). I've put together my findings on the subject on Unmet Hours <a href="https://unmethours.com/question/3102/how-do-you-model-exhaust-fans-in-equest/">here</a> in some kind of tutorial that I hope is helpful. <br></li></ul><p><br></p><p>Do the above and your unmet hours disappear.</p><p><br></p><p>Additionally:<br></p><ul><li>Throttle range of 0.3°R seems pretty aggressive to me.<br></li><li>when you use baseboards and want to oversize, use the system's sizing ratio</li></ul><br></div><div>Hope this helps,<br></div><div>Julien<br></div><div><br></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><div>--<br>Julien Marrec, EBCP, BPI MFBA<br>Energy&Sustainability Engineer<br>T: +33 6 95 14 42 13<br><span style="color:rgb(0,0,0)"><br></span><span style="color:rgb(0,0,0)">LinkedIn (en) : <span style="color:rgb(0,0,0)"><a href="http://www.linkedin.com/in/julienmarrec" target="_blank">www.linkedin.com/in/julienmarrec</a><br></span>LinkedIn (fr) : <a href="http://www.linkedin.com/in/julienmarrec/fr" target="_blank">www.linkedin.com/in/julienmarrec/fr</a></span><br><span style="color:rgb(0,0,0)"><a href="http://www.linkedin.com/in/julienmarrec" target="_blank"></a></span></div></div></div></div>

Anybody have any ideas?<br><br></div>Thanks,<br></div>Mike Campbell<br></div>
