RE: [EnergyPlus_Support] Zone mean air temperature
Mike,
I have just run the file for all 8760 hours of the year. What I am in fact getting is temperature convergence to my heating set-point for the first month of every simulation (the hourly temepratures were obtained from one simulated month) then the temperatures all of a sudden disregard the setpoints. It seems the heating system "runs out" by February though I am not sure why. I have enclosed a graph in the "Sam Roose" folder to demonstrate this problem. Thanks again,
Sam Roose

When I try the same thing the average of the hourly values matches
the monthly value. Do you perhaps have a schedule on the monthly
value which is suppressing certain hours of the day? If not, please
send your files so I can reproduce the problem.
