Cheers mate, simple when you know how. That worked a treat. Now i
just have to work out how to wire up the 2 port and the cylinder stat
(which i will buy at the weekend maybe).

Of course, the problem now is that as the central heating is on all
the time (pump is controlled by the stat), the hot water is on
constantly. The sooner i get this cylinder stat and valve in the
better i think.

The pump is controlled by the stat - but only when the original programmer
tells it to - so you can still have it on only at specified times if you
wish. In other words, if the programmer says "No Heating", then No heating
it is, regardless of what the stat says.
