Trane THT2849 Limit 318518-761 the 2821303S is engineered toThe Trane THT2849 Limit is a high performance thermal safety control engineered for demanding commercial and industrial HVAC applications. Operating as a critical safeguard within the system's high limit safety circuit, this adjustable high limit switch features a sensing range of 180 230F. When plenum or heat exchanger temperatures exceed the specific setpoint, the switch interrupts the 24V signal to the gas valve or ignition control, effectively
