There is too much air in your pump. Also the tubing clearly shows that there is still a lot of air in your loop.
You have a lot of swirls in your aquatube so the air which comes in is also sucked in by the pump again... To deaerate the loop you should let the pump run at a low frequency for a while.
Thanks for the reply. Right now I have the jumper off. so that the pump runs at 49Hz. as I have to put the jumper for the pump to circulate more slowly?
If you place the jumper before you start the pump it will only reset the pump to its factory defaults as soon as you start it. If you place the jumper while the pump is running it will enter the deaeration mode which continuously starts and stops the pump.
By default the pump is set to automatic mode which means it will try to run as fast as possible. In your case this is not ideal because of the air bubbles inside the aquatube.
Following the manual. putting the jumper on the jumper 1 2 Turn off the pump 56Hz which is somewhat faster than tending all jumper off (49Hz) now no longer makes me noise.
That does not look like our ball valve. That opening looks strange to me. Maybe a faulty one where the drilling to mount to valve has gone through the entire fitting.
The blue line is the rpm signal reported from the fan. Nothing special that it is not flat. Some fans show erratic values especially when the voltage is too low for their internal electronic.
The aquaero works fine: the red line which represents the power at the output is flat.
