Hi Lloyd,
I'll be needing one of these. Are they still available? I'm based in South Manchester. You don't mention a price, or are they free to a good home?
I've read that people can still have trouble with the 130 switches, so the 140 seems better. Is that what you've upgraded with?
My boiler should be here in a couple of days, so I'm anticipating this work will need to be done.
Cheers,
Ross
