[Equest-users] Error Messages

[Eric Cody]

I have basement unit heaters that I have defined as heating ventilation
systems because the basement has makeup air connected to an ERV system. I
get this error message for all of these systems and a huge amount of
unheated hours. If I change either the design temperature or max entering
air temperature to match the other, I get an error saying that the air flow
will be to high (which makes sence).

Any suggestions?
