Those are two much better options. Now I'm curious to see what effect the 8760 schedule will have on performance since I've always tried to stay clear of this method. Right now I have about 3500 components in the model, so adding another 52 + 365 components should be relatively tolerable in terms of load time. I'd also like to see what the effect on simulation time will be. The biggest drawback for me is that the schedules section of the Component Tree will become very bloated and possible un-navigatable, so I can see why this might need to wait until the end. <o:p></o:p></p></div><p class=MsoNormal style='margin-bottom:12.0pt'>It just occurred to me that I could also run 2 separate parametric runs: one which locks out above the exhaust air temperature (72) and the other that locks out 17 degrees below the exhaust temperature (55).

lang=FR-CA>I'm trying to model a heat recovery device on a 100% OA VAV unit. The supply air temperature setpoint is a constant 55 F throughout the year. To maximize the savings, we will be locking out the heat recovery when the outside air is between 55 and 72 F. When the outside drybulb is less than 55, we will have pre/re-heat savings, and when the outside drybulb is greater than 72 we will have sensible cooling savings. The closest control scheme that I can find to this in eQuest is to set ERV-RUN-CTRL = "OA Exhaust DT", set ERV-RECOVER-MODE = "OA Cooling" and OA-EXHAUST-DT = 0. But unfortunately, this will not pick up the heating savings. </span><o:p></o:p></p></div><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><span lang=FR-CA>Does anyone know of a better way to model this control?</span><o:p></o:p></p></div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=FR-CA>Aaron</span><o:p></o:p></p></div></div></div><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto'><span lang=FR-CA><br>______________________________________________________________________<br>This email has been scanned by the Symantec Email Security.cloud service.<br>______________________________________________________________________</span><o:p></o:p></p></div></div></div><p class=MsoNormal><br><br clear=all><br>-- <o:p></o:p></p><div><p class=MsoNormal>Sent from my DynaTAC 8000x<o:p></o:p></p></div></div><p class=MsoNormal><br>______________________________________________________________________<br>This email has been scanned by the Symantec Email Security.cloud service.<br>______________________________________________________________________<o:p></o:p></p></div></body></html>
