Safety Thermostat 127c Effective May 2024 CHANGED by PAVONI to 122C Clip and s/s nut are included Manually Resettable. We highly recommend using thermal paste when installing this thermostat (see link below). If you haven't tried resetting this component, here's a link to Stefano's How-To video on You Tube. https://bit.ly/SEC-P14a-Reset If you are replacing the older non-resettable P-15A thermofuse, here are instructions on how to retrofit this on your machine. You can also see Stefano's You Tube video on this link. Use the screw from your P-15A. Start by applying the thermal grease on the base of the P-14A, then align its clip with the threaded hole in the base of the element, thread the new nut (included with P-14A) onto your old screw, then screw through the clip into the boiler. Tighten the nut down until it holds the P-14A securely against the boiler.
