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

Pmin2 : this parameter is only available when the operating mode is set
to P+P and the parameter Aux. Con. is set to "1" to enable operation of
twin booster sets. This parameter defines the secondary (slave) pump
start-up pressure when the primary (master) pump can no longer meet the
system demands. The parameter can be set from a minimum of 0.5 Bar to
Auto-reset interval: during operation of the pump, if water supply on
intake fails temporarily, Brio Top shuts off the power supply to the motor
to avoid any damage. This screen enables the user to set after how many
minutes the device should auto-reset to check renewed availability of water
on intake. If the attempt is successful, Brio Top exits automatically from
N° auto-reset tests: this parameter defines the number of attempts made by
Brio Top to try an resolve a shutdown caused by dry running conditions.
When this limit is exceeded, the system shuts down and user intervention is
required. The auto-reset is disabled if this value is set to zero. The
maximum admissible number of attempts is 100. Use keys + and – to
Delay on stop: this parameter enables the user to define after how many
seconds the electric pump is stopped following closure of all utilities in
mode P+F. At low flow rates, if frequent pump start-ups and shutdowns
occur, increase the shutdown delay to render operation more uniform. An
increase to this parameter may also be useful to eliminate excessively
24H anti-seizure protection this parameter enables the activation of a
function that automatically starts up the pump after 24 hours of disuse. If
this function is activated, and the pump is not started up for 24 hours, Brio
Top overrides to a cycle of 15 seconds to prevent system disuse from
leading to mechanical seizure of parts (e.g. the seal), maintaining system
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
operation and protection of the system if temperatures are close to or
below 0°C!!
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
