Description
The Trane CNT03783 Limit Control is a temperature-sensitive switch used to monitor heating equipment by responding to excessive internal temperatures. It opens the circuit when the sensed temperature reaches approximately 220F, interrupt operation in overheating conditions within the unit. In HVAC systems, it is commonly used in packaged rooftop units and furnaces where it is mounted near the heat exchanger or airflow path. It is a control element ensuring equipment shutdown under high-limit conditions and maintaining operating temperature boundaries during heating cycles.
