Resideo L8148A1017 Aquastat Relay/high limit 140 °F-240 °F | PartsHnC

The Resideo L8148A1017 Aquastat Relay/High Limit is a crucial safety device used in hydronic heating systems. It functions as a combination switch and temperature safeguard. The Aquastat is immersed in water within the boiler, constantly monitoring the water temperature. If the water temperature rises beyond the user-set limit (between 140°F and 240°F), the Aquastat automatically shuts down the burner to prevent overheating. Additionally, it functions as a relay, switching on the burner and circulator pump based on the thermostat's signals. This ensures efficient boiler operation and maintains consistent water temperature for your heating system. The L8148A1017 is compatible with 120V, 60Hz electrical systems and requires vertical mounting for proper operation. Overall, the Resideo L8148A1017 Aquastat Relay/High Limit safeguards your hydronic heating system from potential damage caused by overheating, while ensuring its efficient operation.
