over heat stat is a saftey device, it would be illegal to 'adjust it'
try giving us a better description of ur problem....
if ur on about the temp goin too high on the dial on the front, its a presure guage. the temp is indicated by the lights.
if your presure is going over to 3 bar, with the filling loop disconnected, and ur expansion tank has 1 bar (when system empty) in it, i would start lookin at the plate heat exchanger. if this had a hole in it the domestic water would pass through into the heating side.
