<b>Subject:</b> [Equest-users] Why Is There No Heating Capacity in PVAV Zones
WhenConverted From PSZ in Detailed Edit?<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Everyone,
I converted a model with a bunch of Pkgd Single Zone units (furnace heat, DX
cooling) to a Pkgd Var Vol system (electric heat, DX cooling) with zones in
Detailed Edit. The converted program ran but the unmet heating hours increased
greatly. I checked the new PVAVS zones, and they are grouped correctly under
the Pkgd Var Vol system, but the program is not assigning any heating capacity
to the individual zones. I checked the heating capacities in the SV-A reports
and all of the zone capacities are 0. I then built a Design Wizard Pkgd Var Vol
model and started comparing the HVAC navigation tree screens to the Detailed
Edit converted model HVAC navigation tree screens and found some discrepancies.
I found that the converted Detailed Edit zones lacked the minimum flow ratio
(0.3) so I added that in. I also discovered that the thermostat type didn’t
convert to Reverse Acting so I fixed that. I don’t see any other differences
between the Design Wizard HVAC navigation tree screens and the converted
Detailed Edit HVAC navigation tree screens, and yet the fact remains, I am not
get any heating capacity to show up in SV-A in the Detailed Edit converted
model. So, there is something else I need to change, but I can’t think what.</span><o:p></o:p></p>
