Resideo AQ25244B Aquatrol Universal Inject and Mix Boiler Reset Control Panel DHW Priority

Product Description

The RESIDEO AQ25244B Aquatrol Injection/Mixing Boiler Reset Control provides energy-efficient outdoor temperature compensated control of a high-temperature boiler loop and lower temperature mixed loop in residential hydronic heating systems. It converts a single-zone heating system to Zone of Greatest Demand control, with outdoor reset for increased energy efficiency and reduced boiler cycling.

• Displays outdoor temperature on all AQ1000 thermostats when used with an AQ12C10 outdoor sensor (included).
• Features an intuitive programming interface and central program of zone set points and setback.
• Offers zoning control for up to four zones, expandable to 64 zones using expansion panels.

Product Highlights

This control panel provides simplified, energy-efficient control for hydronic heating systems, optimizing boiler operation and zoning.
