• Adaptive variable speed control, including automatic, proportional pressure, constant pressure and constant speed operating modes.

• Automatic night mode to reduce energy consumption during periods of low demand.

• ECM permanent magnet technology enhances energy efficiency and supports ErP compliance.

• Automatic venting cycle to minimise trapped air and improve system reliability.

• Robust cast iron housing with carbon bearings designed for commercial plant‑room conditions.

• Continuous duty (S1) rating for sustained operation under varying loads.

• LED display control panel for straightforward configuration and status feedback.

• Built‑in protections against over‑current, over‑temperature and over‑voltage events.

• ErP compliant to align with modern energy‑efficiency regulations.

• Two‑year manufacturer’s warranty for quality assurance.
