10. Priority of settings

The external forced-control signals will influence the settings available on the
pump control panel and with the R100. However, the pump can always be
set to max. curve duty or to stop on the control panel or with the R100.
If two or more functions are activated at the same time, the pump will operate
according to the setting with the highest priority.
The priority of the settings is as shown in the table:
Priority

Not active when the pump is controlled via bus.
Only active when the pump is controlled via bus.
Example: If the pump has been forced to stop via an external signal, the
pump control panel, the R100 or a bus signal can only set the pump to max.
curve.
As illustrated in the table, the pump does not react to external signals (max.
curve and min. curve) when the pump is controlled via bus. If the pump is to
react to external signals (max. curve and min. curve), the system must be
configured for that function.
