Trane THT2184 Temp Control mario The unit is rated forThe Trane THT2184 Temp Control is an essential SPST (Single Pole Single Throw) temperature actuation switch designed for rigorous industrial and HVACR environments. Engineered for reliability, this thermostat control switch functions with a specific cut out (open) at 265F and a cut in (close) at 31F. This calibration makes it ideal for evaporator defrost control or high temperature limit protection, preventing equipment damage under extreme thermal
