LA Sensitivity adjustment

The sensitivity can be changed by following these steps:
1. Enter the PIN (see chapter "12.2 PIN Entry").
2. Tap and hold the
3. The display shows the code entry.
The default value is 2 and can be changed from 1 to 7. The sensitivity corresponds to the switching
threshold for the alarm and is to be understood as follows:
Sensor state Sensitivity
Dry 0 %
7 30 %
6 40 %
5 50 %
4 60 %
3 70 %
2 80 % (Standard)
1 90 %
Wet 100 %
The cancellation limit is always 15 % below the sensitivity limit. If the sensitivity value of 2 is not changed,
the alarm is triggered at 80 % and is automatically cancelled as soon as it falls below 65 %.
