ENGLISH
2. Faulty non-return valve.
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.
1. Supply voltage too low.
2. Excessive drop in voltage
on the line.
One or more devices have
sensitive parameters not
aligned.

2. Service the non-return valve as described in paragraph 12.3.
Check the air pressure through the valve in the technical compartment. If
water comes out when checking, the vessel is broken: assistance service.
Otherwise restore the air pressure according to the equation (par. 1.4).
Calibrate the expansion vessel pressure or configure the parameters SP
and/or RP so as to satisfy the equation (par. 1.4).
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.
Press the ^ key on the device which we are sure has the most recent and
correct configuration of the parameters.
