DESCRIPTION
Nettuno
is an electronic device, employing inverter-based technology, which controls electric pump stopping and starting functions.
Thanks to the particular type of technology used, it can modulate the frequency (Hz) of the motor’s input current to adjust the speed (rpm)
according to the water demand by the system.
This way, the value of the pressure reaching the user appliances is maintained constant all the time and the motor's absorption is always
proportional to the actual system requirements, resulting in notable energy savings over time.

EMC
This product has been tested according to the standards stated in the EC declaration of conformity in one of the typical conditions of use,
using shielded cables both on input and output (motor cable 15 metres, without auxiliary connections). However, experience has shown
that significant variations in the level of EMC disturbance can occur when the type and length of cable used is changed, as well as their
position, type of motor used etc.
If other equipment is subject to disturbance, contact the manufacturer to assess additional solutions to reduce electromagnetic disturbance.
