Well I have a suprima 60 and I have had problems with no temp control and banging...etc...I have changed the PCB to the new modern one as suggested in my last post......and the system has worked fine for the last three weeks...but then at 0630 in the morning....the system vents to the expantion tank and the boiler starts banging...like it did before...and it has dont it again this morning at 0730.......with the hot water and heating on...
Its like there is no temp control again...........but I get the feeling its not the boiler now....
Is there any reason that the water on the system can boil with out the boiler going into lock out?.....or reaching its selected temp?
Or is the New PCB U/S......
The pump seems to be working ok.....is was on setting three..but now I am trying it on setting two....
I could do a test to see if the system behaves its self on just selecting the hot water or heating seperatly.......
But I suppose my question is.....What things cause system boiling....
erm what other info.........the water in the system when this does happen is very..hot...........
