Wiring required for Combi boiler electronic programmer...

[spada01]

The electronic programmer will need a standard T & E power connection.

What other wires are required? Is there a 3 or 4 wire feed that goes from the programmer back to the boiler and what cable is this run in? Also is it HV or LV?

Usually LV. Usually HV too.

Crystal ball or boiler make/model would help.

I would have thought usually mains voltage.
But you need to tell us make and model of the boiler AND the programmer AND the room thermostat AND the zone valve(s) you intend to use.

Do I?

I was under the impression all programmers have a standard fitting backplate now and the only difference is 2 or 3 wires being run...

The boiler is a combi.

Do the wires tend to come with the programmer or will I need to buy seperately? If LV, then presumably standard bell wire will do

Don't be a tool. Is the make/model of your boiler some kind of state secret? Or perhaps you bought an Ideal?

Most but not all have the industry std backplate but not all programmers have the same internal wiring.

A lot of combis have volt free connections. If you put the wrong clock on it is a costly mistake, new circuit board. Other boilers are wired totally different, hence the what boiler, valves etc.

This could take a while. I'm going for my dinner.

My boiler is connected with fibre optic cable and runs on Pixie Dust!!

Why are you fitting a programmer on a combi? not saying it can't be done but tbh, you sound a little clueless. Not answering this perfectly reasonable question was also a bit daft.

Bell wire is for bells and chimes, not boilers. No wiring is supplied with the programmer. I understood from your previous posts that you were planning on re-wiring your own property, frankly, this is a worrying development

...Why are you fitting a programmer on a combi? ...

Err....Huh?
How else is he supposed to control when the boiler goes on?

Everything else in your post I agree with.

Most people would fit a programmable thermostat. If he's fitting a programmer then he also needs a separate thermostat which is not only complicating things, but the 230V ones (what I assume the OP means by HV) will almost certainly fry his combi.

Programmable stats most certainly do not have standard back plates, 230V connections or the other 4 wire connections he's talking about.

Is what I meant, which is why I think he is not too knowledgeable on the subject.

The boiler's a Gloworm Betacom 24

I was looking at:

But judging by your posts I should get a controller with built in thermostat so like:

[twgas]

the second one is the better option, the progammer in the first link controls HW as well as CH, which you wouldn't, usually, want with a combi.
I would strongly recommend you get a pro in to do the wiring as you do not appear to be competent, judging by your questions.

Heatserve, there is no reason why bell wire could not be used, But one has to establish what voltage is to be switched. There are boilers that have 24 volt circuit for timer or programmer. See nothing wrong in this case.
