AUTOADAPT ™
AUTOADAPT™ is an automatic control mode designed for heating applications and is unique to the Grundfos MAGNA and ALPHA™. AUTOADAPT™
not only adjusts the pumps performance along the set control curve, but
it can also actually optimize the control curve for the particular system.
While ensuring comfort, this automatic adaptive control can reduce
energy consumption compared to traditional circulators by more than
70%.
