[EnergyPlus_Support] Re: EnergyPlus Newbie - HVAC help

["don_shirey" <shirey@xxxxxxxxxxxxxxxxxx>]

When you installed EnergyPlus, a subfolder named "Example Files" 
should have been loaded onto your computer. FurnaceWithDXSystem.idf 
should be included in this folder.

If you can't find it, I just uploaded it to the 
EnergyPlus_Support@yahoogroups site under "Files".

This example file will show you how to set thermostats and reference 
them to zones.  Also, take a look at the documentation for further 
assistance.
