ALPHA2 15-55 is a high-efficiency ECM variable speed circulator designed for a variety of heating and hot-water recirculation applications. The pump features AUTOADAPT and constant-pressure control modes. It features a constant pressure control mode and a constant curve with each three settings. The factory default setting is AUTOADAPT which continuously adjusts the pump performance to the actual heat demand, i.e. the size of the system and the changing heat demand during the YR. The function will find the setting that provides optimal comfort with minimal energy consumption. It contributes to fast, safe and easy commissioning. The intuitive one-button operation and LED display makes the selection of the settings easy. The large LED display shows the current energy consumption in Watts and estimated flow in gallons per minute.
