The Webasto 11113837D three-pin temperature and overheat sensing unit monitors coolant temperature at the heat exchanger outlet and transmits the value to the control unit as electrical resistance. Built for Webasto (Spheros, Valeo) Thermo E 200 and Thermo E 320 heaters, it combines water temperature detection with integrated overheating protection. When temperature exceeds 125°C, the sensor triggers heater shutdown and lockout for safe operation, and it does not require manual reset. Supplied assembled with an integrated sealing ring for easier installation.
