<P class=MsoNormal>Hi All,</P>
<DIV>
<DIV>
<P class=MsoNormal> </P>
<P class=MsoNormal>I am still fairly new to equest and I am having a bit of trouble with setting up my HVAC. I created a building model using the equest wizard and now I have made a number of changes within the detailed DOE2 interface. The building uses air source heat pumps for the HVAC and I would like to change the EER/COP values without going back to the wizard, but I cannot figure where these values are stored. Is there an easy way to make changes like that within DOE2?</P>
<P class=MsoNormal> </P>
<P class=MsoNormal>Thanks,</P>
<P class=MsoNormal>Michael Shields</P>
