Description
The Weil McLain 510-312-019 Limit Control with Well is a temperature-sensing safety control used in boiler systems to monitor and regulate water temperature. It includes an immersion well that allows accurate sensing of heat levels inside the system without direct contact with the water. In boiler-based HVAC applications, it is installed in the heat exchanger or supply line to prevent overheating by shutting down or cycling the burner when preset temperature limits are reached. This helps protect internal components, maintain safe operating conditions, and ensure stable heating performance in residential and light commercial systems.
