Fw: Replacing and automating the Central Heating switch (PIC fixed)

[Gareth Cook <g@xxxxxxxxxx>]

Scanning the comfort group archives it would seem so - just not on a
RIO
board - so might have to do some rekigging. Even with th expansion board
i've only got a few inputs left.

Hopefully I wont need any resistor nonsense. I'll whizz to Maplin and grab
one of these bad biys - thanks for the heads up !
