The start/stop and digital inputs will influence the number of pos-
sible settings.
By means of the R100, the pump can always be set to max. curve
duty or to stop.
If two or more functions are activated at the same time, the pump
will operate according to the function with the highest priority.
The priority of the settings is as shown in the following tables:
