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�
7.2 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)�
►
Let the normal flow circulate in the installation�
►
Press the pushbutton and keep it pressed�
> LED 9 lights, after approx� 5 s it flashes�
►
Release the pushbutton�
The unit is now adapted to your flow conditions� It passes into the operating mode,
the display should now show example 1�
Note: The adjustment affects the switch point: It is increased proportionally (maxi-
mum up to LED 7)�
