VVT Systems

[ddcman]

Can anyone explain how a Variable Volume Variable Temperature (VVT) HVAC control system works, specifically, how should the zone dampers be controlled, and how should the bypass damper be controlled.
Thanks

A couple of questions I forgot to ask in reference to VVT Systems: 1. Is an airflow pickup required at zone damper locations.
2. How is VVT system different from a standard VAV box type of system.

Thanks again!
