These pumps are said to be self -regulating as TRV's open and shut etc.
However, they do require choosing one setting out of 3 first.
How do they regulate themselves? - I guess it cannot be any vanes moving but must be the electronics sensing the flwo resisitance (= electrical load) and adjusting the speed. Can anyone confirm that?
and if they are so clever, do I need to fit a differential bypass on my 100% trv system?
