[Equest-users] Fw: large number of unmet hours

I noticed a couple things. To use the E8 system as an example:
1) You've assigned a supply flow rate and OA flow rate at the zone of 500 CFM, yet if you let eQuest auto-size this system, it wants 1500+ CFM. So your system is undersized based on the constructions/loads you've entered in eQuest. Also, is it really 100% OA?
2) The indoor design temperatures for each zone are 120F for cooling and 40F for heating, yet your thermostat schedule is in the 60s and 70s. Make this match your real indoor design temps.
3) Your "MIN DESIGN FLOW" for a number of your zones is set to 0.00 cfm/ft2. Why?

Subject: [Equest-users] Fw: large number of unmet hours
can anybody tell me why I have such a large number
of unmet hours in zone E8, E9 and E10 ? I found a lot
of advises in this user-list. Most of them are dealing the
extension of the throttling range from 2 to 4 or 6 which
only helps a little bit (especially for other zones).
Thank you in advance and with best regards
