
The pump starts and stops continuously.
There are leaks from the system. Check the various hydraulic connections. Check on display if there are
any pressure drops when the valves are closed. Check for the possible presence of dirt in the check valve
of Brio Top preventing total closure, and if necessary clean by means of a compressed air jet. Install a
small expansion vessel on outlet from Brio Top.

The device frequently signals dry running conditions.
The pump intake hose, during periods of system disuse, drains preventing pump filling and subsequent
restart. Check sealing efficiency of the base valve (if fitted).

With very low water flow rates, pump operation is irregular.
The water flow rate is too low, and is thus not detected by the device, with consequent pump shutdown.
Install a small expansion vessel (1-2 litres) to enhance system flexibility and reduce the number of
restarts.

The system pressure has risen above the set value in Pmax.
If the ice protection or mechanical seizure protection devices have triggered, pressure may increase over
the set values as the pump is operated in override for 15 seconds, regardless of the values set in Pmax and
Pmin.

The device does not turn on
The electronic board may be damaged; arrange for the device to be checked by the manufacturer.
