1=invert the di-

tion
dP This parameter 0–99
is the value for
starting the
pump after a
stop, calculated
as a percent-
age of the re-
quired set point
value. Exam-
ple: SET
PRESS =
4.0bar dP =
90% (3.6 bar).
If the pressure
in the system
reaches the re-
quired pressure
of 4.0 bar and
there is no ad-
ditional con-
sumption, the
converter disa-
bles the pump.
As consump-
tion increases
and the pres-
sure decreas-
es, the convert-
er turns on the
pump when the
pressure falls
below the dP
value of 3.6
bar.
WARNING:
If the parameter EL=0 and MP=0, the
pump is not protected against dry run-
ning. The warranty does not cover dam-
age to the electric pump caused by in-
correct configuration.
• For motor cables longer than 30 m, it may be
necessary to increase motor current by 10%.
Check this in relation to the type of installation
and cable.
– Example: In=5A, set the parameter at 5.5A.
