Worcester permanent live wiring

[richardd]

I have wired a worcester with a permanent live from the fuse spur ( that also controls the honeywell controls ) direct to boiler . I have also wired in the honeywell smartfit ( splan ) wiring center (from boiler to wiring center )

When I select for everything to go of on the internal programmer in the house the worcester dosent go of and just keeps the house at 21 degree. If you want to turn the worcester permantely of you have to do this at the on/off at the boiler which is installed in an outhouse ( a bit inconvenient ) do you guys think I have wired this wrong if so what is the problem.

do you guys think I have wired this wrong if so what is the problem.

Yep you've wired it wrong, the problem is you have messed up your switched live circuit somewhere giving your boiler a permenant live on the switched live. That's what it sounds like anyhoo's!!!!

 

[mfgs]

Wired wrong. Time to trace what you have done and look in the instructions.

I have put my switched live which is Lr in the boiler to L in the wiring center . I have also put my Ls in the boiler to Ls in the wiring center . Is this were the problem is.

 

[richardd]

Would I be correct in saying my Lr within the boiler should go to Ls in the wiring center and my Ls in the boiler should got to PL in the wiring center.

 

[richardd]

Boiler connections below / SMARTFIT CONNECTIONS 5 TERMINALS ( L / E / N / SL / PL )

E ( Straight to earth on the smartfit earth )
LR ( UNSURE ) have going to L in smartfit at the moment
LS ( UNSURE ) have going to SL in th smartfit at the moment
N ( straight to neutral on smartfit)
L ( permanent supply to boiler form fuse spur )
N ( permanent supply to boiler from fuse spur )


So what terminal in the smarfit do I connect the Lr and Ls from the boiler to. I know the rest ( earth and neutral ) and have the permanent live connected to the boiler from the fuse spur.

Ls and Ns from the boiler are your permanent live and neutral supplies to the wiring centre.
Lr is the switch live

 

[diamondgas]

Whats the model of your boiler? It's looking like you Lr boiler should go to SL on the controler. No wire needed from Ls on boiler, I think? LS is 'live suply', LR is 'live return'. I think!

If you have supplied both the boiler and the wiring centre from the fused spur then you do not use Ls and Ns on the boiler.

SL on the wiring centre goes to Lr on the boiler. There should also be a wire from PL on the wiring centre to Lz on terminal ST2 of the boiler for the pump overrun.

The correct way to wire it is fused spur straight to the boiler LNE
5 core (or 2 x 3 cores) from boiler to wiring centre. Ls - L, Ns - N, Lr - SL, Lz - PL + an earth.

 

[richardd]

I have supplied a live form the fused spur to the boiler and the wiring center. I have also wired the pump straight to the boiler into the s2 terminal.

So basically tamz I just have to single core the Lr on the boiler and to the SL on wiring center.

 

[tamz]

That is all you need obviously as long as you supplied the N and E from the spur to the boiler too.

 

[richardd]

Yeah I ran a three core from the spur to the s10. ( L Terminal ) ( N terminal ) ( E terminal ) .

 

[tamz]

Lr to SL is all you need then.

 

[richardd]

Thanks tams the cable carrying Lr to SL does it need to incorporate an earth.

 

[tamz]

Not if you have an earth to the wiring centre
