[Equest-users] System Help

I had tried that and from all appearances there is a central heating coil. Yet, when I look at the SS-B output report it shows that all the heating is happening at the zone.

If I understand your challenger here, I think you need to input
SYSTEM:HEAT-SET-T to simulate a central heating coil. This is needed in
any Single Duct/Multi-Zone system that does not require a CONTROL-ZONE.
(VAVS, PVAVS, RHFS, HVSYS, PIU, IU, etc.) You can get more information
in the DOE-2 help system that comes with eQUEST. See Volume 2/HVAC
Components/SYSTEM/Airside Control/Heating Availability and Supply
Temperature. I hope this helps!
