Your normal flow is below the representation
range of the display�
2 setting options:
► Change the switch point (→ 7.3).
► Carry out high-flow adjustment (→ 7.4).
3
Your normal flow exceeds the representation
range of the display (LED 9 flashes)�
► Carry out high-flow adjustment (→ 7.4).
You can restore the factory setting any time (→ 7.8).
7.3 Change switch point SP1 for flow (optional)
For the factory setting the switch point is at LED 7� A change makes sense in the
following cases:
• 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)�
Proceed as follows:
► Press the button
briefly�
> The switch point LED flashes�
► Press
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�
7.4 High-flow adjustment (optional)
The unit determines the existing flow as normal flow and adapts the display repre-
sentation (all LEDs except the switch point LED light green)�
Proceed as follows:
► Let the normal flow circulate in the installation�
► Press and keep it pressed�
> LED 9 lights, after approx� 5 s it flashes�
► Release the button�
