This Burnham Commercial Limit/Harness Assembly is designed for warm start applications. The assembly is a critical component in the heating system, responsible for regulating the temperature within the system to ensure it doesn't exceed a certain limit. It achieves this by monitoring the temperature and sending signals to the control system to either increase or decrease heat production based on the readings. The harness, on the other hand, is a collection of wires that transmits electricity and signals within the heating system. It connects various parts of the system, allowing them to communicate and function together seamlessly. This assembly is compatible with specific Burnham Commercial heating systems and is made from high-quality materials for durability and reliability.
