Expansion vessel empty (insufficient air
pressure) or has broken diaphragm.
Air pressure in the expansion vessel
higher than the system starting pressure.
1. No water.
2. Pump not primed.
3. Setpoint not reachable with the set
RM value.
1. Faulty pressure sensor.
1. Excessive absorption.
2. Pump blocked.

Remedies
1. Check the system, find and
eliminate the leak.
2. Service the non-return
valve as described in par.
9.3.
Check the air pressure in the
expansion vessel. If water is
found to flow out during the
inspection, it means the tank is
broken
Otherwise restore the
pressure according
equation P= SetPoint-1bar.
Set the expansion
pressure or configure the SP
and/or RP parameters in such a
manner as to satisfy
equation P= SetPoint-1bar.
1-2. Prime the pump and check
whether there is air in the pipe.
Check whether the suction or
any filters are blocked.
3. Set a RM value that allows
the setpoint to be reached.
1. Contact the assistance
centre.
1. Fluid too dense. Do not use
the pump for fluids other
than water.
2. Contact the assistance
centre.
1. Check the presence of the
correct supply voltage.
2. Check the section of the
power supply cables.
