Rancilio High Limit Thermostat - 165/15 110V UL The current-production high limit thermostat used by Rancilio, UL approved, without capillary fitting. This version works with the newer boiler cap design that isolates the probe from the boiler via a separate orifice and vertical tube, reducing the chance of the probe contacting the heating element. Trips at 165°C (329°F). SPECIFICATIONS Trip temperature: 165°C (329°F) Voltage: 110V, UL approved Capillary fitting: not included COMPATIBILITY Fits Rancilio Classe 5 (S 1GR and S Tank 1GR) and Classe 5 USB 1GR machines, Epoca 1GR E/07 and S/07 boiler/expansion circuits, and the Silvia Pro and Silvia Pro X home machines, only machines built after S/N 10221269 (PIN 132287, ca. 2015) with the new boiler cap Replaces: 34200354 INSTALLATION An electrical job for a qualified technician, confirm your machine's serial number is past the cutoff before ordering. PRO TIPS Check your serial number against 10221269 before ordering, this version is built for the newer boiler cap with an isolated probe well, and installing it on a pre-2015 boiler configuration won't seat correctly.
