NOTE: If a standard heating pump is replaced by this high-
efficiency pump, the knob can be set (as a reference point
for setting the pump setpoint) on the first, second or third
pump curve (c1, c2, c3) on the scale for three speed stages.
Setting of the delivery head/speed stage
If the knob is turned from the middle position to the left or to
the right, the set setpoint or the selected speed stage
increases. If the knob is turned back again to the middle
position, the set setpoint or the selected speed stage is
reduced. In the ∆p-v control mode, the setting is done in
0.1 m steps.
When the knob is turned, the display changes in the ∆p-v
control mode to the set pump setpoint. The "m" symbol
lights up.
In the three speed stages mode, c1, c2 or c3 is shown for
the respective pump curve
If the knob has not been turned for a duration of two sec-
onds, the display changes back to the current power con-
sumption after flashing five times. The "m" symbol no
longer lights up.
NOTE: By turning the knob to the middle position, the pump
runs at minimum speed and the pump displays the minimal
delivery head.
Factory setting: ∆p-v, ½ H
NOTE: All settings and displays are retained if the mains
supply is interrupted.
