2 setting options:
► Change the switch point (→ 7.1).
► Carry out high flow adjustment (→ 7.2).
3
Your normal flow exceeds the representation
range of the display (LED 9 flashes)�
► Carry out high flow adjustment (→ 7.2).

7.1 Change the switch point (optional)
For the factory setting the switch point is at LED 7� A change makes sense in the
folowing cases:
• the display shows example 2�
• the flow fluctuates much or pulsates�
• a faster response time of the unit is requested (low switch point = fast response
with rising flow, high switch point = fast response with falling flow)�
►
Briefly press the pushbutton
or �
> The switch point LED flashes�
►
Press the pushbutton
or as often as required� Each press of the push-
button shifts the LED by one position in the indicated direction�
Note: If no pushbutton is pressed for 2 s, the unit returns to the operating mode
with the newly set value�
