Changing the Sensitivity
WARNING
This setting should ONLY be changed by a specialist!
Sensitivity here refers to the size of the flow rate, which the system
evaluates as water abstraction or leakage.
Thus the threshold value from the small water withdrawal without
switch-off to the water withdrawal with switch-off (after exceeding
the preset permanent flow duration).
The display of a small permanent water withdrawal or a small leak
remains unaffected by this.
The Fl is preset at the factory with maximum
sensitivity (level 20).
If a leakage has to be tolerated in your application due to the
system (size or type of installation), you can change the sensitivity
of the Fl in 6 steps as follows:
Disconnect the power supply (1) and wait 30 seconds.
Press and hold the Set / Reset button (8).
Now reconnect the power supply unit at the same time.
If the status indicator flashes green/red (after approx. 10 sec.),
you can release the Set / Reset button again.
