6.1 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�

• 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)�
