Filling quantity:
Based on a continually referenced preceding period of time (time window), the unit allows using a
certain number of filling cycles that are separated by pauses from one another. Cycles, pauses and
time windows (time spending) can be freely parameterised.
Example: (default setting)
In the last 480 minutes (time spending) the make-up water quantity per cycle must not exceed 50 litres.
Moreover, it is not permissible to supply this quantity during this time more than three times, and the
pauses between the cycles must be 5 minutes at a minimum.

Note that the values in the filling quantity menu are interdependent. Therefore, it may be necessary
to first parameterise another value before the actual value becomes accessible within the intended
limits. Similarly, setting ranges may be limited by the dependencies. It is advisable, for instance, to
first parameterise a sufficiently sized time window before defining the pauses and the number and
length of cycles

Software version
Readable entry made by manufacturer.
Start
Enter the time and date of the start (traceability) by pressing Start. Before pressing, the date and time
must have been correctly set.
Maintenance
The date of the next maintenance is indicated in parentheses. When this time is reached, the
centralised fault alarm is optionally tripped, and a fault message is displayed to remind the operator.
If it is acknowledged, it will be displayed again after seven days unless ‘Maintenance done’ has been
pressed, thus indicating that the maintenance has already been carried out. The time and date of the
last maintenance as well as the code level are indicated in the upper two lines.
