[Equest-users] Beginner Question on Fan schedule

[Chris Jones]

I don't think the behavior of INTERMITTENT changed from DOE2.1e to 
DOE2.2.  The DOE2.1e Supplement has the same wording as the DOE2.2 manual.

I would add some hourly reports - supply cfm, OA ratio, heating 
energy and cooling energy.   Run for both CONTINUOUS and 
INTERMITTENT.  There may be some differences in the amount of outdoor 
air that is being introduced.
