135 Degree Safety Thermostat

135°C Resettable Safety Thermostat

A 135°C over-temperature safety thermostat with an M4 mounting stud, found in older, out-of-production Sanremo models (such as the "Roma") as well as the current "You" model. It's resettable in the field using a pin through the small hole in its center.

COMPATIBILITY

• Fits: older discontinued Sanremo models (e.g. "Roma") and the current Sanremo "You"
• Replaces: Sanremo #10113049; alternative versions may ship

INSTALLATION

Technician install recommended, this is a boiler-mounted safety component and over-tightening can damage the boiler.

PRO TIPS

• Extreme care is needed threading this in: the stud can snap off inside the boiler if over-tightened. It doesn't need to seat flush, slightly beyond hand-tight is sufficient, and if it stops turning smoothly, stop.
• Smear thermal paste on the sensing head before clamping it down, it fills microscopic gaps between the switch and boiler surface for accurate heat transfer, especially important on pipe-mount installs. It's a heat-transfer aid only, not an adhesive, so don't rely on it to hold the part in place.
