Apparently -- according to the Internet -- that particular brand of wireless controller, the Drayton Digistat, has a weak point in a certain capacitor which is known to fail. It's just that when that capacitor goes, the heating typically refuses to come on at all, rather than coming on spontaneously and being impossible to switch off! Frankly, I should have been a lot less worried by radiators that were stuck cold than by scalding hot ones...
When it fails to switch on, the fault is technically fixable for a small cost if you can source the necessary spare part, solder a circuit board and -- more importantly -- are qualified/competent to work with both mains gas and electricity. I didn't have that error, and wouldn't have been able to handle it myself if I had.
