The Relay / Switching Board on Your HTP 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 HTP systems — including models such as UFT, Elite Premier, Versa Hydro — a failing relay / switching board often shows up as ignition lockout or related symptoms. We diagnose it precisely and install the correct genuine HTP part.
