RE: Replacing and automating the Central Heating switch

["Hawes,Timothy Edward \(GEG\)" <haweste@xxxxxxxxxxxxxxx>]

Gareth,

I'm not sure I completely follow, but I think you're on the right track.
The thermostat needs to stay wired into the circuit but if all you're
doing is replacing the time-clock function then this should work well
:-)

The power to the boiler is usually protected with a 3A fuse :-)

Ian Lowe wrote this FAQ entry which may also be of interest. It's X10
based but the principles should be the same:
