<DIV>I have been working with EnergyPlus's EMS control module and am curious if eQUEST has some of the same capability using User Input Expressions. From what I can tell, the user input expressions are only used to perform calculations based on other user inputs. Is that correct?</DIV>
<DIV> </DIV>
<DIV>I am trying to model an exhaust fan in a crawlspace that keeps crawlspace temperature close to the outdoor air temperature. The sequence is as follows:</DIV>
<DIV> </DIV>
<DIV>- When OA Temp < 32, the EF controls the crawlspace to 32 F</DIV>
<DIV>- Above 32 F, the fan cycles on to maintain <10F delta T between the OA Temp and Crawlspace Temp</DIV>
<DIV> </DIV>
<DIV>This is a relatively easy expression to write in Excel with the hourly reports, but it would be nice if this can be done in eQUEST. Maybe I have been spoiled by the E+ EMS controls. Any suggestions?</DIV>
