Linking A-B will put the heating on permanent, I wouldn't worry unless you have a problem.

UHM =ultimatehandyman.

Referee can be great or boring depending on the players, 4 hours for a best of 7 qualifies as pathetic.

I was trying to associate it to the snooker tournament scuff is on :) That's why it didn't strike me it's the name of this website.

It's just for future reference in case the stat is not working and the boiler can't fire up in really cold weather. I assume I can still turn the boiler on and off from the mains if A-B is linked at the relay or alternatively rewire back the old SM timer ?

UHM - I thought it was something to do with your tournament.

That's a bit ott isn't it ? 7 games and 4 hours ? Well, I wish you luck that the players will give an exciting performance.

Have a good evening and catch up later. Have to cook my dinner now and thanks for your help on the wiring.
