Description; Specifications; Features - Italtecnica Sirio SR23251 Serie Instrucciones Para El Uso

 DESCRIPTION
Sirio is an electronic device, employing inverter-based technology, which controls motor pump stopping
and starting functions.
Thanks to the particular type of techno l o g y u s e d , i t c a n m o d u l a t e t h e f r e q u e n c y ( H z ) o f t h e m o t o r ' s i n p u t
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 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.
