System 3 in Appendix G then you should have one system per zone (as described
in the 90.1 User’s Manual, p.G-23). One thing to check for unmet heating
hours is your zone BASEBOARD-CTRL (assuming you have perimeter heating). Set it
to Thermostatic. If you try to satisfy multiple zones with one single zone
system, try changing the control zone, manually adjusting the supply flow to
individual zones, and/or setting interior walls to “Air” walls where
appropriate (such as for zones where air is supplied to one and returned from
the adjacent zone).<o:p></o:p></span></font></p>

just that – a single zone. You’ll need to have a separate
single zone system created for each zone you need to assign to that system.
Once that is done, eQuest will then be able to address the thermostats in
each zone adequately and you should see a rather dramatic drop in your unmet
heating hours, possibly eliminating them altogether.<o:p></o:p></span></font></p>

have a packaged single zone system using DX cooling and Furnace heating that
serves 7 different zones and is controlled by the corridor zone. This is
supposed to replicate "System 3" in ASHRAE 90.1 appendix G. I
have many unmet heating hours (including my system control zone). I have
let eQuest auto size equipment capacities and and cfm. I have tried doing
everything I can think of to reduce the number of unmet hours. My OA
volumes are pretty small and shouldn't be affecting it. I expected
possibly a few unmet hours in some of the zones, but not in my control zone,
the corridor, and not to this magnitude. I get the following
warning message seen below, I'm not sure what it means by
"Baseboard-Rating"? Any ideas on what this means or how I could
reduce the number of unmet heating hours?</span></font><o:p></o:p></p>
