[EnergyPlus_Support] Re: Heating/Setpoint Controller

["ntraughpee" <matthew.sverre.anderson@xxxxxxxxx>]

PS: As I read it I was understanding that by using the HVACTemplate:System:VAV and having no availability schedule for either the HC/CC it would always be available when needed. Then I added in a constant set point, however from looking at the node temperature points in Results Viewer it is obvious that the HC/CC are operating year long at a constant set point.

The system itself should be putting out like 55 degree air in max cooling, and 100 degree air for max heating. I have been trying to use the OA Temperature reset but again the coils seem to never shut down.

What am I missing?

However, I currently have no schedule for either since there will be many times during the fall/spring where we might need to heat/cool during the same day or during the week.
