I have literally spent an entire day trying to figure out why my boxes will not register downstream duct cfm's. All I want is for the CFM to be scheduled based on the total of the diffusers attached to it. I have checked, double checked, and triple checked all of the connectors. The ducts will total the CFM up to the point of the box, but not INTO the box. Yes, I have read all the help topics. Yes I have Wiki'd my heart out. Thoughts? Encouragement? Help??
