Flow sensor BAXI 620340 AIM 03AT16

Flow sensor AIM 620340 / Baxi 620340 Turbine hot water flow sensor AIM (code 620340) — ideal solution for Baxi boilers of EcoFour, Luna‑3, Luna Duo‑Tec series and similar models. Supplied assembled with filter and turbine, integrated into the hydraulic group, and quickly responds to flow changes: ensures instant switching of the boiler to DHW mode at flow ≥ 3 l/min and shutdown when flow drops below 2.5 l/min. Magnetic Hall effect sensor generates a precise control signal. Reliably and efficiently regulates water temperature in modern wall-hung boilers.
