The Trane THT0485 is an automatic switch that protects an HVAC system from losing efficiency or going to a high limit. This is a safety thermostat and controls temperature automatically within the predetermined limits. In this case, the THT0485 is programmed to turn off the system between 115°F and 140°F. It protects your HVAC system from overheating and damage while doing so safely. The Trane is one of the most commonly used components across furnaces, heaters, and other heating systems that have to be controlled under the strictest temperature differences.
