Although it was a long post, it seemed a bit short of specifics!

If you look he

you'll find pointers to a lot of info.

You *do* need a room stat, connected into your programmer.

If it's a programmable digital one (try it, you'll like it), the CH can be
left on at the programmer contiuously, the stat will look after the
temperature.

You need the radiator in the same room _not_ to have a TRV or the stat will
fight the TRV, all other rads can have TRVs.

That's very basic; no doubt if I'm very wrong on any point the corrections
will pour in, but I guess you wante to get started HTH
