damage caused by ice, it is good practice not to use Brio Top and the electric pump in environments
where temperatures can fall below 4°C. The activation of this function is not sufficient to guarantee
operation and protection of the system if temperatures are close to or below 0°C!!
time of the current overload safety device is inversely proportional to the entity of the overload in
progress; therefore a slight overload will lead to a more delayed trip time while a more significant
overload will accelerate the trip time. The parameter is settable from 0.5 to 16 A by means of the keys
"+" and "-". To deactivate the current control protection of the motor, press the key "-" until the text
"OFF" appears on display. CAUTION: the factory setting is OFF and therefore a maximum current value
must be set to activate the protection.
Aux. Description
Con.
0 No function activated for auxiliary contacts
1 Enables communication between two Brio Top units within a twin booster set with
automatic alternation of pumps
2 Sets up the auxiliary contact for an external enable signal (e.g. float, timer, irrigation
controller) and enables the relay output (terminals 5 and 6 on the terminal board) for any
error signals. The relay contact closes in the event of an alarm.
3 Sets up the auxiliary contact for an external enable signal (e.g. float, timer, irrigation
controller) and enables the relay output (terminals 5 and 6 on the terminal board) for
pump operation signals. The relay contact closes while the pump is running.
4 Enables communication between a Brio Top unit and an inverter Sirio within a twin
booster set.

4°C ice protection: this parameter enables activation of a function that
may help prevent damage due to lowering of ambient temperatures and
the risk of ice formation. In particular, if the ambient temperature falls
below 4°C, Brio Top starts up the pump every 30 minutes for a duration
of 15 seconds, to avoid, when possible, the rapid freezing of the water
inside the pump. CAUTION: although this function can reduce the risk of
Imax : this optional parameter enables entry of the maximum current
absorbed by the electric pump in routine conditions, to enable shutdown of
the motor in the event of excessive absorption. The motor is also shut
down event if the current read during operation is below 0.5 A following
interruption of the connection between the motor and Brio Top. The trip
Auxiliary Contact: this parameter enables the user to assign a specific
function to the auxiliary contacts available on Brio Top according to the
scheme below:
Limit pressure: this parameter defines a pressure threshold over which the
overpressure protection is activated. The factory setting is OFF, to indicate
that the protection is disabled. To set a limit pressure, use keys "+" and "-".
To disable the function, press the "+" key until the text OFF is displayed.
