1
The factory setting is suitable for the appli-
cation�
►
No further settings are required�
2
Your normal flow is below the representation
range of the display�
2 setting options:
► Change the switch point (→ 6.1).
► Carry out high flow adjustment (→ 6.2).
3
Your normal flow exceeds the representation
range of the display (LED 9 flashes)�
► Carry out high flow adjustment (→ 6.2).
You can restore the factory setting any time
�
7.1 Change the switch point (optional)
For the factory setting the switch point is at LED 7� A change makes sense if:
• the display shows example 2�
• the flow fluctuates much or pulsates�
• if a faster response time of the unit is requested (low switch point = fast re-
sponse with rising flow, high switch point = fast response with falling flow)�

> The switch point LED flashes�
►
Press the pushbutton [
] or [
] as often as required� Each press of the
pushbutton shifts the LED by one position in the indicated direction�
If no pushbutton is pressed for 2 s, the unit returns to the operating mode
with the newly set value�
