Quite!

Another design gotcha, which resulted in my returning a B&Q set
some years ago, is to have no retained memory of the mode chosen,
so that if on a timer, it is impossible to arrange matters so
that it stays static next time it is switched on. :-(

I am glad to say that the three sets of lights outside do retain their
mode - not that it matters too much outside. Unfortunately the lights on
the Christmas tree don't
