Re: [EnergyPlus_Support] About the heating load

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

What type of system is this for?  Are there other heating coils such as reheat 
coils?  Are the zone setpoints being maintained?  Check the inputs in the 
SYSTEM SIZING object.  Coil sizing is determined by the specified supply air 
temperatures, the system flow rate, and the mixed air temperature at the design 
load condition.
