[EnergyPlus_Support] Re: EnergyPlus Newbie - HVAC help


Thanks again for your help...two more questions...I don't have the 
FurnaceWithDXSystem.idf file where can I get it?  Also, the results 
seem to indicate that my unit heaters and/or unitary system are not 
running b/c winter temperatures are only about 15C.  In the summer 
all temps are higher than environmental as well.  I have thermostats, 
but I'm not sure if they are connected, as the heaters and unitary 
system do not reference them or a zone in any way that I have 
programmed so far.  

Also, I keep getting an error message that demand side inlet pipe 
cannot be found, even though I have it listed as a "PIPE".  Any ideas?

Thank you very much for your help...
