Trane THT1248 Thermostat 340793-762 With its robust internal constructionThe Trane THT1248 Thermostat is a critical high limit switch engineered for precision thermal protection in residential and light commercial HVAC systems. Functioning as a safety critical normally closed (NC) control, this limit thermostat is designed to mechanically break the electrical circuit when the system reaches 150F. This automated disruption immediately shuts down burners or heating elements, preventing heat induced damage to the heat
