Description
The Resideo L6006C1034/B High-Low Limit Aquastat with Circulator Control is a temperature-sensing regulator component used in hydronic heating systems to monitor water temperature inside boilers and storage tanks in HVAC systems. It tracks a liquid temperature and operates internal switching to manage high-limit protection, low-limit control, and circulator operation based on set conditions. Installed on boiler vessels or piping sections, it helps maintain stable operating temperatures, prevents overheating, and ensures proper activation of the circulation pump when required. It is applied in residential and commercial heating systems where controlled temperature regulation and safe system cycling are required.
