Grundfos service staff are unaware of this setting. my 3 yellows were constantly burning. He was working at high speed for 24 hours. Thank you. Thanks to this video, I was able to change the setting and decrease the speed.

Yes but what do the settings mean and what setting should be used for a typical house heating system?

I am not a plumber but would like to know at what flow speed the pump is set at...in the video clip it only shows how to change the flow but does not explain which each setting means...how many lights for fast flow and how many for slow..confused...

how will I know at what speed my pump is running. Thanks

What mode and speed for underfloor heating?

LED status and setting is a little tricky

Reci mi prijatelju od čega zavisi i sta se postiže odredjenom brzinom pumpi imam tri pumpe jedna pre miš ventila i dve posle miš ventila na koju brzinu koja pumpa treba da radi hvala unapred.

So where is the bleed screw.
