Has anyone ever figured out how to fix the OA percentage of an air system? I'm trying to peg a system at 30%, but it seems like something out there is overrriding the system diagram.

Yeah,

depending on your current network you may need to add an additional mixing damper set to simulate (as you need a separate set for each control type. Once you have done this add an independent controller with sensor set to sense main fan flowrate and set to 30% at the inlet to the mixing damper
