<div>So, after analyzing the hourly reports, I have been able to get the return temperature up to the temperature that I am looking for by setting the thermostat schedule at that temperature....however, I cannot get the supply air temperature low enough to meet the delta T of my system. It seems as though eQUEST will take whatever your thermostat setpoint is, then supply air about 10 degrees below that point to meet the thermostat setting (I need a higher delta T than 10 deg). </div>
<div> </div>
<div>Does anyone have any advice of how to set that supply air temp without compromising the return air temp?</div>
<div> </div>
<div>Thanks for all of your help. Sorry for all of the emails. I am working by myself on this and have few other resources to turn to besides stttttrrrruuuuuuuuggggggggggggggling through it on my own and the eQUEST archives.<br>

<div>Hey All, </div>
<div><br>I am trying to control my systems based on the delta T of the supply and return air. I have looked around quite a bit to solve how to control this parameter, but can only think/find one solution that I am skeptical about. </div>
<div> </div>
<div>The only way that I could figure how to control this is to:</div>
<div> </div>
<div>- set the supply air temperature under the Air-Side HVAC System under the heating and cooling tabs...the "Zone Entering Max Supply Temp" and the "Zone Entering Min Supply Temp" parameters, respectively </div>
<div>- then set the zone indoor design temperature (and reset the thermostat setpoints to the same temperature) to control the return temperature</div>
<div> </div>
<div> </div>
<div>One other question, is there any way to set the cooling "zone entering min supply temp" (under Air-Side HVAC System Parameters/ cooling sub-tab) to a value greater than 70 F... an error pops up if you try to set this value higher than 70 deg F. Same thing for the heating "zone entering max supply temp"</div>

<div>Thank you all very much for the help.</div>
