• Energy Efficient: Features a best-in-class Energy Efficiency Index (EEI) of 0.18 or less to significantly reduce annual household power consumption by up to 80%
• Simple Configuration: Intuitive one turn knob allows for instant switching between proportional pressure, constant pressure, or fixed speed modes to suit radiators or underfloor heating
• Compact Fitment: Designed with a 130 mm port-to-port length and G 1 1/2 inch threads for a direct drop-in replacement in tight spaces or specific manifold configurations
• System Protection: Integrated dry-run protection and automatic air-purge function help maintain long-term reliability by clearing trapped air and preventing motor damage
• Visual Diagnostics: Clear multicolor LED provides real-time feedback on operation status, standby mode, or error alerts to simplify maintenance for engineers and homeowners
