My apologies.

I hadn't noticed that you were the originator of this topic.

Any ideas if the wiring is correct in the photo??

 

[Phill Peck]

No it's not
Terminal 3 is zone 1on
Terminal 4 is zone 1off

Also your earths (assuming they earths) are in terminal 1 not the earth connection bottom left.

Essentially you are a wire short

The problem could also be as bunny man pointed out

Either way wiring incorrect

You have wired it up as a hard wired si, have a look at the instructions for the tp5000rf, the rf is totally different wiring.

 

[macka09]

I have looked but can't see what's different.

This it's what's differnt you havnt got a wire in terminal 4 for starters

I have wired hundreds of these. Can't figure out why they've used 7 cores and don't have enough you need one cable with 5 cores to the boiler simple

Have a look at page 7 on the link charnwood posted, the diagram RX1 is the one you want.

 

[macka09]

Surely the amount of wires from the boiler are standard.

Terminal 4 is zone 1off

[macka09]

So how can I make up the numbers on wires??

 

[picasso]

First thing you gotta do is identify what each wire does, chances are you have enough wires.

 

[macka09]

The wire from the left is the boiler, right wire is fuse spur...

 

[picasso]

Well your stat is wired up correctly so the fault must be at the boiler end.

 

[macka09]

The other chap said I'm missing a wire for number 4

 

[picasso]

Number 4 isint used, in your stat it is heating off and take the earths out of number one and put them in a choc block but dont leave them there.
