Causes
20 restarts with stand-by time less than
5s
The pump is not properly primed or
there is air inside the pump casing. The
pump restarts whenever the system
pressure is under the restart pressure
threshold.
20 restarts with pump RUN time less
than 10s
The power is under the switch-off
attempt threshold for 60s with set-point
pressure reached
The pump is at the limit of the allowed
power input and the pressure is less
than 1.5bar for 20s
