TROUBLESHOOTING


When one of the system valves is opened the pump does not start or starts only after a few
seconds.
The set Pmin value is too low, or a check valve has been fitted downline of the device. Check the setting
of the parameter Pmin.
If the parameter "Aux. Con." is set to "2" or "3" and an electric float is used, check to ensure correct
operation. If no electric float is used, check that the jumper is wired on the relative terminals.
Ensure correct connection between Brio Top and the electric pump

The pump does not stop
The check valve inside Brio Top may be blocked in the open position; ensure correct valve movement
and remove any foreign bodies by means of compressed air if necessary.
The sensor reading the valve position is faulty; arrange for the device to be checked by the manufacturer.

On closure of the valves, the pump stops but restarts after a few seconds without any leaks
from the system.
The difference between the values Pmin and Pmax is too small, and the pressure drop that occurs on
pump shutdown is sufficient to enable restart. Increase the value Pmax or reduce the value Pmin. Increase
the size of the expansion vessel installed.

Dry running: this message appears when the system is shut down following
absence of water on pump intake. If the auto-reset function is enabled, Brio
Top automatically attempts to restart and check for renewed availability of
water. To remove the error message from the display immediately, simply
press the central key "reset".
Current Overload: this alarm is displayed when electric pump absorption
exceeds the maximum set current as entered in the parameter Imax; this may
occur following intensive use of the electric pump, continuous restarts at
close intervals, problems with the motor windings, seizure of the pump rotor
or following problems with the electrical connection between the motor and
Overpressure: when this alarm trips, this means that Brio Top has detected
a system pressure value over the value set in the parameter "Plimit". This
may occur in applications with the pump under load conditions, i.e. when the
pump pressure is added to the filling pressure on inlet. If the error occurs
frequently, try to increase the parameter Plimit or contact the installer for
