FLOW RATE (l/h)
Values referred to a mix of water and 30% glycol.
The circulator speed is controlled through PWM signal and
varies according to the thermal gradient between solar col-
lectors and storage.
Pay attention to the system overall flow resistance (ex-
changer, solar collectors and pipes) at the maximum flow
rate conditions provided.
