The Outdoor Reset Sensor on Your Viessmann 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 Viessmann systems — including models such as Vitodens 100-W, Vitodens 200-W, Vitodens 050-W — a failing outdoor reset sensor often shows up as f2 no flame or related symptoms. We diagnose it precisely and install the correct genuine Viessmann part.
