Hi All,

I am a new user of openstudio. I am trying to model a 90.1 baseline for a hotel using a central VAV system with electric parallel fan box reheat. But I am getting too much over heating. I use the warmest setpoint to in my air loop. However when I plot the warmest zone, I see that the autosize capacity cannot lower the air temperature to setpoint level. I also checked that the reheat is not active as well. I thought using the warmest set point manager would resolve this. Why is the autosizing algorithm under sizing the cooling capacity? Thanks
