Warnings indicate restricted pump function. The pump continues to operate in re-
stricted mode (emergency operation).
Depending on the cause of the warning, emergency operation leads to a restriction
of the control function and even reactivation of a fixed speed.
If the pump identifies as part of permanent monitoring that the cause of the warn-
ing no longer applies, the warning is revoked and operation resumes.
If there is a warning message, the display is permanently on and the green LED indicator
is off.
