A question we sometimes get from contractors on replacement applications is if they can use some of our products with products from another manufacturer. Many times you can.

The DuraZone dampers have different terminals than Jackson Systems dampers; however they can still work together with the use of one (1) SPDT relay. Below is a drawing that shows how to wire a Jackson Systems zone panel to a DuroZone damper.
