We have a retrofit project with pressure dependent VAV boxes. I'm going to use NB-VAV.
1. Do I need a supply sensor for this type of application?
2. In the manual I see that damper position based on estimated flow (there is no flow sensor in the box). I don't understand how to configure the controller in NB-Pro if I don't know max flow. Is it possible to configure control based strictly on space temperature signal (cooling)?
