<DIV>Hi Group,</DIV>
<DIV> </DIV>
<DIV>My system is a simple VAV. When I click to add an ERV, it ties up my
machine completely for about 3-4 minutes and then throws up the error for
“maximum number of tracked changes exceeded.” But it accepts the ERV and
lets me configure it. This results in a vast decrease in heating energy,
but a large increase in cooling energy. Weather is Atlanta. I don’t
understand why cooling energy would increase with the simple addition of an
ERV.</DIV>
<DIV> </DIV>
<DIV>Any thoughts? </DIV>
<DIV> </DIV>
<DIV>Thanks!</DIV>
