Constant speed

The circulators of this range can work at constant speed on 3 preset curves. In this case, the pump works as a usual pump without regulation and the power consumption remains constant. When this mode is active the LED remains steadily lit; in this case the colour of the LED indicates the selected curve (“blue” the lowest curve, “green” the intermediate curve, and “yellow” the highest curve). To switch from one curve to another, briefly press the button to return to variable pressure mode, select the desired curve (indicated by the colour of the LED) and then press and hold down the button
