sorry about flippancy of previous. I know its not helping.
Think netaheat has poss only got o-heat stat cut out on it.
You should be able to get M.I if you go to baxi partsarena- more I.T savvy types may be able to supply a link
the netaheat didn't have an overheat as standard only on profile did this appear, if the pcb was faulty and new one fitted it should work as soon as you turn it on, what is happening, if anything, when you turn it on. if you have a profile then overheat is underneath boiler .
