Description
The Trane THT02848 High Limit Thermostat Assembly is a temperature-actuated safety switch used in a heating unit to monitor internal air or heat exchanger temperature and protect the equipment from overheating in HVAC systems. It is installed within compatible air handlers or rooftop units, typically in the airflow or heat transfer section, where it senses rising temperatures during heating operation. The switch operates with a defined temperature range, opening at 150F and resetting at 120F, interrupting the control circuit when excessive temperature conditions are detected. As part of the safety and control system.
