 DESCRIPTION
Sirio is an electronic device, employing inverter-based technology, which controls the 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 alter the
speed (rpm) according to the water delivery rate required from the system.
This way, the value of the pressure reaching the user appliances remains constant and the motor's absorption is always
proportional to the actual system requirements, resulting in notable energy savings over time.
