Priority Of Settings - Grundfos MAGNA3 50-40 F N Installation And Operating Instructions Manual

4.6 Priority of settings

The external forced-control signals will influence the settings
available on the pump control panel or with the Grundfos GO
Remote. However, the pump can always be set to max. curve
duty or to stop on the pump control panel or with the
Grundfos GO Remote.
If two or more functions are enabled 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 below.
Example: If the pump has been forced to stop via an external
signal, the pump control panel or the Grundfos GO Remote can
only set the pump to max. curve.
