Re: [EnergyPlus_Support] Re: Zone controls and thermostats



I have recreated the data shown below, however, I do not know what is 
causing it. I was able to get reasonable results by changing the cooling 
set point to 24 and the heating set point to 23. You may have to adjust 
these set points to a different value based on your climate. I will 
forward this file to someone more able to diagnose the problem.
