The PARTS TO YOUR DOOR 50361 is a 48-inch sensor designed for use with the Hydrolevel 4200 aquastat control. This sensor monitors water temperature or immersion conditions within a hydronic heating system, feeding signal data back to the aquastat to regulate boiler operation. It is a direct-fit replacement component typically installed by licensed plumbers or HVAC technicians servicing hot-water boiler systems. At 0.20 pounds, the part is lightweight and straightforward to handle during installation or service calls.
This sensor is used in residential and light-commercial hydronic heating applications where the Hydrolevel 4200 aquastat is the primary control device. It is suited for hot-water boiler systems that require accurate immersion-style temperature sensing to maintain safe and efficient operation. The 48-inch length provides sufficient reach for standard boiler well or line configurations.
Designed for use with the Hydrolevel 4200 aquastat control in hydronic hot-water boiler systems.
Installation of this sensor should be performed by a licensed HVAC technician or plumber. Shut down boiler power and allow the system to cool before removing or inserting any immersion sensor. Ensure the sensor is fully seated in the aquastat well and that any sealing fittings are properly secured to prevent leaks. Follow local mechanical codes and the aquastat manufacturer guidelines during service.
