Possible causes
A - No power

setting is unsuitable to the type of
installation.
B2 - Faulty electrical connections or

pump out of service
STOP
B3 - PRESET "OUT OF SERVICE"
B4-1 - PRESET in temporary shut
down due to "DRY RUNNING" due to
lack of water
RY RU
B4-2 - Maximum pump pressure is
DRY RUNNING
insufficient

C-1 - Filters or pipes may be partly
blocked

Solutions
A - Check the electrical connections
B1 - Set the Pm at a higher value.
B2 - Check the electrical connections
and that the pump is working
B3 - Reset PRESET
(See Operation, point 3).
B4-1 - Wait for the automatic restart or press
START to restart manually (See Operation, point 4a)
B4-2-1 - Replace the pump with one with more
suitable characteristics
B4-2-2 - Set Pm at a lower value
B5 - Wait for the automatic restart or press START
to restart manually (See Operation, point 4b).
Remove any cause of leakage from system or
install an expansion tank
B6 - Check if the setting of the maximum current
(Imax) is congruent with the data of the pumps'
rating plate. If after manually restarting the pump
after correctly setting PRESET, it again signals an
anomaly, check that the motor has no mechanical
or electrical problems.
C-1 - Check the water pipes
C-2 - Check that the valve is not blocked by any
foreign objects and clean if necessary
D - Check the hydraulic connections and repair
any leaks.
E-1 - Make sure that all taps are turned off and
that there are no leaks within the system
E-2 - Check that the valve is not blocked by any
foreign objects and clean if necessary
