Operating data display
The device alternately displays the suction pressure and
discharge pressure as well as the differential pressure or head.
Recording and analysing of the load profile
The operating hours of the pump in the
different modes of operation are recorded in
a load profile and saved in a non-volatile
memory (protected against power failure).
The energy efficiency symbol is displayed
when a potential for optimisation is
recognised.
Qualitative indication of the pump's current operating point
The flashing segment indicates the position of the current
operating point on the generalised characteristic curve.

For some pump characteristics, no differentiation is made between the low-flow operating conditions in the curve's first
two quarters (both flashing simultaneously).
