Electricity problem

[Major Fallout]

I have been waiting for ages for this thermostat thingy and now it's time to wire it up.

But before I do I just want to double check with you guys if I'm wiring it right.




I'm thinking.

1. Ground/negative out
2. Live/positive out
3. Ground/negative in
4. Live/positive in
5 and 6. Temperature sensor.

Try:
1. Live (brown or red)
2. Live out (brown or red)
3. Live (brown or red)
4. Neutral (blue or black)
5 and 6. Temperature sensor.

There doesn't appear to be a ground (green/yellow) connection.

That makes more sense.

But why is 4 connected to 2 in the picture?

[Major Fallout]

Oh unless "the load" is the thing I'm powering?

It is. You need a neutral connection & a switched live to complete the circuit.

Another switched live?

[mikeveal]

No, just connect it up as per the diagram and the pin out in my earlier post.

LOAD is 'the thing' you're letting the thermostat switch on and off.

No - the switched live is what appears at 2. Live connected to 1, then through the internal switch so 2 outputs a live.

Thank you so much.

I really don't think I should be let loose with wires.

Sorry but I'd have to agree! Positive & negative mentioned with mains wiring.

[mikeveal]

+1
If this isn't blindingly obvious from the detail in post 2, you should get someone in to do it for you.

Mains electricity has a tendency to set fire to things or (and) make your fingers tingle if not handled correctly. It is dangerous stuff.


Not my area of expertise, but I'd expect this to come under class P reg's anyway. That is you're not supposed to DIY, you're supposed to get some one in for this.

[Censorious]

It shouldn't come into part P as the wiring is presumably already there and a new digital stat is replacing an old one.

Fitting a new ring main?
That's a different matter!

[Major Fallout]

It works!
Thanks guys!

Hard to believe but I used to build computers for a job a lifetime ago, and rewired my house (ring circuit) then had an electrician check and sign it off. But I have never been good with wiring diagrams. Must be something to do with being dyslexic?

No. I'm great at spelling but can't do wiring diagrams.

Neutral is common and connected together. Although it shows it in the drawing the physical connection could be elsewhere
