As part of a job I'm doing the customers wants a hive fitted. I had a look yesterday but got confused. The current wiring in the programmer is L. N. NO to both hw & ch. Common to both linked into the L. The Hive has L. N. And NO & NC for both hw & ch. My question is where do I put the current commons or do I just forget those and leave the NC empty? I don't do a great deal of wiring but my sparky can't get out until next week and I need to get this job invoices and am nearly done apart from the stat.
 
No = normally open so your heating on / hot water on goes here

Nc = normally closed so your heating off / hot water off 3 port
 
Sorry. Should've mentioned it's 2 ports and a system boiler.

So you won't need to wire your nc ports just your no

Treat us as a normal prog

Thanks for the answers chaps. So just to confirm. Hive reciever. L, N, NO (CH & HW) Disconnect wired stat from wiring centre. Pair hive witless stat. All should be good? Anything else I'm missing?

Yes but don't shove them both in the same port :) (think you know but just checking)
 
Lol. I'm not good at wiring but yes. I meant in their individual terminals! Thanks again.
 
Is it a twin channel hive that you are fitting? And if it is a modern ish timer the back plate on the new one should be the same as the old.

Whatnot I do with the existing Commons?

For what ? As it should be pritty much a straight swap remove the room stat and the old timer wire

Wire the new hive sender unit in where the terminal block is

Run a new 5 core or 2 x 3 cores and wire up in terminal block
 
Sorry. I just looked at my last reply which didn't make much sense! Yes. It's heating & hot water programmer. Cable are all behind tiles so can't really run a new cable. Shaun has explained the wiring well for me. It's just what to do with the current commons that I'm unsure of. Thanks again though to everyone for your help as always.
 
What timer is there at the moment. On older timers normally the commons are just links.
 
The Honeywell square one with 3 sliders. I think one goes into ch C then links across to the hw c then to the L
