Hi all,

I need some help figuring out the source of unmet heating hours right now. Using RTU 4-2 as the example (only 2 zones), here is the load summary for these spaces (spaces are highlighted in black):

The best I can tell from this report (correct me if I'm wrong) is that the spaces require approximately 38.5 kBtu/h total of heating to satisfy the load. The unit has 430 kBtu/h (or rather, MBH) of heat. Yet, I still have a ton of unmet heating hours. The unit is constant volume. Thoughts?
