Press "F2" to switch the mode menu to the current input menu
Selection option:
If you select the "F1" button (0 - 20 mA), for example, the following appears on the
display:
Display indicator:
The quantity (ppm) of ClO2 added and the max. main water line flow are entered
in this menu.
NOTE The value for the amount of ClO2 added is a "starting
value" which does not necessarily have to correspond
to a ClO2 measurement downstream of the installation
because the control calculation is unable to factor in
consumption in the solution line!
●
Press "F1" to switch to the variable field "0.00".
Press the "up", "down" buttons to change the numerical value and the "arrow left"
and "arrow right" buttons to change the input field.

Display indicator:
The requisite installation capacity is now calculated here, relative to the amount
to be added (ppm) and the existing max. flowrate of H 2 O.
Example: Default quantity of ClO2:
Main water volume:
max. installation capacity:
NOTE If the calculated installation capacity is greater than the
size of the installation, only the rating for the
installations (e.g. 10 g/h) can be dosed.
●
Press "Enter" to switch to the menu:
Display indicator:
The max. and min. volume of water which can be supplied with ClO 2 through the
set quantity to be added (ppm) and the installation size are specified in this menu.
