[Equest-users] User Input Expressions

[Tim Johnson]

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?
 
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:
 
- When OA Temp < 32, the EF controls the crawlspace to 32 F
- Above 32 F, the fan cycles on to maintain <10F delta T between the OA
Temp and Crawlspace Temp
 
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?
