The FWE T-STATH1 Thermostat 90-190 °F is a temperature control device used in commercial holding and warming equipment to regulate heat within a defined range. It senses the internal temperature and opens or closes its internal switch to maintain a set point between 90 °F and 190 °F, signalling the heating system to cycle on or off accordingly. Installed in heated cabinets, buffet warmers, and proofing units, it forms part of the control system that helps keep food at secure and consistent service temperatures. It supports accurate temperature regulation and helps prevent overheating or under-heating during normal operation.
