Hello eQuesters,

I am having a lot of trouble getting my unmet heating hours down. The only system I can get to work is the multi-zone packaged system, but this system has some simultaneous heating and cooling, and isn't the best match for us. For some reason when I use the packaged variable volume system (which is the best match for us) my unmet heating hours go absolutely crazy. It's almost like the program isn't recognizing the zone reheat, so areas aren't getting heated properly. Has anyone had a similar issue? I attached my building model, if someone would be willing to take a look it's AHU-1 and AHU-2 that we are having issues with.

Thanks,
