What it is
The Viessmann 7817311 is a sensor well: a sleeve that accepts a temperature sensor and holds it in position against the pipe or vessel wall. It isolates the sensor from the system water so the sensor reads temperature through the well wall rather than sitting in direct contact with the medium. The part is listed under Viessmann part number 7817311.
Before you order
- Confirm 7817311 matches the part number listed for the appliance or the number marked on the existing well.
- Check the existing sensor and well against the new part before fitting, as the sensor and well are matched to one another.
- Isolate and drain the relevant section of the system before removing the old well.
