Multi zone VAV AHU: Control of actuated exhaust dampers without fans (PART 5.N.8)

1. The exhaust damper is enabled when the associated supply fan is proven on uSupFan = true, and disabled otherwise.
2. When enabled, a P-only control loop modulates the exhaust damper to maintain a building static pressure of dpBui, which is by default 12 Pa (0.05 inchWC).
3. When uSupFan = false, the damper is closed.
