[EnergyPlus_Support] A few problems with controls

["asheaffe" <sheaffer@xxxxxxx>]

Boy am I confused.  I have several problems with the 1EOnly file.  

I want to have a ventilation system that supplies 100% OA.  The 
ventilation systems needs to have a constant 12.8 C supply temp from 
the cooling coil, and a constant 20 C supply temp from the heating 
coil, at a constant flow rate of 0.092m3/s.  Then I want a PTAC to 
take over the supplemental heating and cooling loads throughout the 
year (no OA flow through the PTAC, zone recirculation only).

I can't seem to get the cooling coil to supply a constant 12.8, 
regardless of the setpoint manager that I have installed.  

Then, when I specify a flow rate for that main system, it is 
automatically applied (against my wishes) to the PTAC.  How do I 
make it so the flow through the PTAC is autosized based on the 
supplemental heating and cooling needs?  

Also, for a system like this where I have two different flows being 
supplied at different temperatures to the room, what should I use 
for the heating and cooling design temp fields in the zone sizing?

Thanks,

Andrew
