Designed for circulating liquids in heating systems.\u003c\/p\u003e\u003cp\u003eIt features a constant pressure control mode and a proportional pressure control mode each with three settings, and constant pressure and proportional pressure AUTOADAPT. The constant and proportional pressure AUTOADAPT mode enables the pump to continuously adjust the pump performance to the actual heat demand, i.e. the size of the system and the changing heat demands during the year. The function will find the setting that provides optimal comfort with minimal energy consumption. It contributes to fast, safe and easy commissioning.\u003c\/p\u003e\u003cp\u003eThe one-button operation and LED display makes the selection of the settings easy.\u003c\/p\u003e\u003cp\u003eALPHA2 materials and design are resistant to blockage from magnetite found in hydronic systems.\u003c\/p\u003e\u003cp\u003eALPHA2 is complete with an integrated check-valve.\u003c\/p\u003e\u003cp\u003eIt is
