I've just replaced my venerable Worcester 35 with one of these and my
wife is bemoaning the lack of a 'heating advance' button as we called it
here.
Does such a thing exist, I've trawled the hand books and the only thing
that comes close is something called 'party mode' which requires one of
a myriad similar buttons to be pressed 3 times. Now seeing as pressing
the wrong button 3 times may well alter the setting for th_nd_world
setting I'd be pleased if there was an easier way that I've missed.

Any ideas?
