How to check the hydraulic flow rate of a Dualsun solar system?

Edited

Checking the hydraulic flow rate ensures that the Dualsun solar system is working properly.
To do so, you have to operate the solar control and read the flow rate at the flow meter of the solar station.
 

With a Dualsun SLL solar station

  1. Press the button

  2. Press button (2) to select MAN1

  3. Press button (2) to activate the MAN1 setting

  4. Turn the knob (3) to set MAN1 to MAX

  5. Press button (2) to confirm the setting

  6. Remove the cover of the solar station

  7. Read the hydraulic flow rate using the flow meter (10)

  8. Reading at the upper edge of the flowmeter float, see flow display below

  9. Reset the circulator to AUTO mode

  10. Replace the cover of the solar station

  Read the flow rate at the top edge of the flowmeter float.

The flow rate should correspond to the number of panels connected:
Flow rate [L/min] = 1 L/min/panel x number SPRING panels
