Hey all, I have a motorised Drayton Zone Valve (2 Port) and I'm wondering what way round these should be fitted? On the valve body (brass) are the letters 'A' and 'B'. The natural state of this valve is closed (position 'A'). Is the 'A' the inlet and the 'B' the outlet? Many thanks in...

Yes - I completely removed the back plate from the system and wired just two wires - Brown (live 240) to L on the backplate and Blue (Neg 0v) to N on the backplate. I've just redon my test and I got the same results as before. So, my 522 is faulty. :( It's off to the plumbers in the...

Thanks to all - query answered.

I shouldn't laugh, but I did! Thanks for your reply. Can you please tell me when the white wire becomes 'live'? Thanks

Thanks Mick, but, as mentioned in my post I will be Installing. Could you please be a little more specific in your answers...? I.e how the other wires are used? when they become live etc? I really do appreciate your time and efforts. Thanks
