Re: [EnergyPlus_Support] control dampers

["Michael J. Witte" <mjwitte@xxxxxxxx>]

I am not sure I understand exactly what your bypass will do.  The dual duct and 
VAV dampers are controlled by the zone thermostat to meet the zone setpoint.  
The central heating coil in such a system is controlled by a setpoint manager 
to meet a specified leaving air temperature off the coil.  See the 
DDAutoSize.idf and 5ZoneAuto.idf example files.
