Hello,
I keep getting this error for each zone thousands of times per simulation. I'm using the HVAC PTAC Template. Is there a solution besides creating a performance curve? In the same building I'm getting unrealistic heating energy demand (almost zero). Could these warnings be the source of my low heating loads?
