If an external controller is installed, the pump is able to change from one constant curve to another, depending

on the value of the external signal.

You can also set the pump to operate according to the maximum or minimum curve, like an uncontrolled pump:

• Use the maximum-curve mode in periods in which a maximum flow is required. This operating mode is for

instance suitable for hot-water priority.

• Use the minimum-curve mode in periods in which a minimum flow is required. This operating mode is for

instance suitable for manual night setback if you do not want automatic night setback.
