The Outdoor Reset Sensor on Your Weil-McLain Boiler

The outdoor reset sensor lets the boiler lower its water temperature in milder weather, improving comfort and condensing efficiency. A failed sensor disables reset and can leave the boiler running hotter than needed.

On Weil-McLain systems — including models such as ECO, ECO Tec, Ultra — a failing outdoor reset sensor often shows up as low water cutoff trip or related symptoms. We diagnose it precisely and install the correct genuine Weil-McLain part.
