[EnergyPlus_Support] Residential heater sizing and cycling question

["taharvey2001" <taharvey@xxxxxxxxxxxxxxxx>]

I'd like to be able to model a standard constant volume residential
forced air heater in EnergyPlus and see the impact of Sizing on
efficiency and heater cycling. 

I haven't been able to figure out how to model the heater
appropriately in E+ or and make sure the heater has sufficiently small
timestep resolution so the heater can cycle, and the difference in
efficiency can be seen. 

As I understand, the HVAC system timestep is decoupled from the 15
minute building timestep, allowing it to free-run with an adaptive
timestep (down to seconds if need be) - is this true, and is there
anything that need to be done to enable this behavior? Is there anyway
to see the high-res HVAC transients in the output?

What is the best way to get a const. volume, const BTU heater to model
residential forced air systems?

thanks,

troy
