Adjusting Flow Meters in Distributor with Wilo Pump & Setting WILO-Yonos PARA RS 25/6 to AUTO Mode

Hello,
I have a problem - I do not know how to adjust flow meters in a distributor with a Wilo pump, exactly like this:

Pytan, how do I adjust the upper flowmeters? If I unscrew, they are all twisting. Tomorrow I plan to flood the system, and I do not want to damage anything.
Another question, the pump I have: WILO -Yonos PARA RS 25/6 as in the picture, I can not find instructions on how to set it to AUTO mode.

Greetings.

You turn the white knob on the bottom bar and look at the flow at the top of the appropriate rotameter.
greetings

So the rotameters at the top are not regulated at all?
Do you know how to set this pump to automatic mode?

Hello. Turn the white knobs to the max, then remove the red caps from the rotameters, underneath there is a place for turning the rotameter. Flows are pre-set to 1.5-2 liters on each cycle, you wait calmly a day or two until it starts to heat up, or you regulate when you heat it too low, where you get too cold. Of course, the adjustment is to proceed smoothly, no sudden changes in flows. You set the pump so that its capacity is sufficient to ensure adequate flows. The thermostat under the pump sets the temperature to 25-35 degrees depending on how the floor heating is made.

Ok, unscrew them during flooding, before or after?

During filling, all flow meters have been turned on the max and white knobs. After filling with water, we completely vent the heating system, start the pump and set the flows.

Thanks, everything is blown and it's going to be nice.
