The Relay / Switching Board on Your Dunkirk Boiler

Relay and switching boards coordinate multiple circulators or zone valves and the boiler on multi-zone hydronic systems. A failed relay leaves a zone or pump that will not run, or runs constantly.

On Dunkirk systems — including models such as Q90-200, XEB, PWX — a failing relay / switching board often shows up as no heat or related symptoms. We diagnose it precisely and install the correct genuine Dunkirk part.
