Bypass damper or not?

[marty]

I am getting ready to install two, 2 zone systems in a new construction home. I have used EWC before in residential retrofit situations and always used bypass dampers. Would I be able to do install without using bypass dampers?

I think you should call our office, for I have a few questions too ask about your system. You can go to EWCControls.com open manual, go to EBD open submiital sheet. Review the drawing of a by-pass , then go to RD-HD application notes review. Any question please call.

Do you have a number that I need to call and or a contact person?
