I am trying to simulate a large VA outpatient clinic using CBECC-Com (for California compliance), and keep getting this error message:

* Severe * ControlCompOutput:AirTerminal:SingleDuct:ParallelPIU:Reheat:VAV3-241125-TRMHEAT 105, Min Control Flow is > Max Control Flow * ~~~ * Acuated Node=DHW1 - HOTWATER DEMAND SPLITTER OUTLET NODE 101 MinFlow=[0.000], Max Flow=-1.493E-002 * ~~~ * During Warmup, Environment=SAN-JOSE-INTL-AP ANN CLG 0.4% CONDNS DB=>MCWB, at Simulation time=08/21 23:45 - 24:00

There is nothing unusual about that VAV box... there are over 100 more like it. It is on the middle floor of a 3 story building, but not at the epicenter. I am using the EnergyPro GUI for input, so there might be a translation issue. If someone can better describe this error, so I can better pinpoint the problem, that would help. Does anyone know what is this about?
