Values referring to a mix of water and glycol at 30% and
bend (4) 7.5 m.
The speed of the circulator is set to a fixed factory value (ON-
OFF), but can be controlled by means of the PWM signal and
changes according to the temperature difference between solar
collectors and storage.
Pay attention to the system overall flow resistance (exchanger,
solar collectors and pipes) at the maximum flow rate conditions
provided.
