WIRING programmer issue

[joehat]

As per pics, I can see the conversion chart and how it's done, but theirs no number 6 connection in the old programmer?

Is this needed, ? As it says to terminate it 2?

I haven't done many programmers, usually their simple but this ones got me.
Pics of new WIREING and current programmer needing replacing.

Thanks for any replays and help?

Hang on... Just because your a sparky doesn't mean you know how to wire a thermostat etc?

Lee I might be a bit dozy tonight but 3 and 4 are a NC and NO respectively - so only 1 of those is an 'on' .

Haha yea just looked at pic was trying to remember the terminals as I was typing 1 is on, 3 off, 4 on.....i got there in the end I think lol been a long day.

Does it not?? In the circles I work in being a sparky means you are a Stonemason, Carpenter, plasterer, general consultant for all matters relating to just about anything, and oh yes, well capable of getting the tools out (brain, Multimeter, experience) and working out just about owt. Certainly sorting out a central heating timer is not an outrageous challenge. I don't know how some of you lads get through the week to be honest. Can you run that past me again? "Just because your a sparky doesn't mean you know how to wire a thermostat etc?" ummmmmm.

Okay, so why did the old one not need an off /nc term 6?

Same as Dave says, your a sparky, just get the meter out, brain in gear and crack on. S'only a timer.

Meter? There's perfectly clear written instruction in the first pic, and wiring diagrams for the old an new.

Or is reading a basic wiring diagram not part of the job anymore?

Read it again with the question mark at the end. been a long day has it?

Ohhh cheeky. yes it has actually. I must try and recognise people being facetious I seem to be having trouble lately. Can you be a bit more obvious in the meantime lol?

Not much help at all, just because I'm a sparky does not mean I know how to install thermostats Ect,

Good grief man it's a box with two switches in it, nothing special! There's a clear label telling you exactly what each pin on the old programmer does using the most basic of notations to identify the contacts, what more do you need?
Com, nc and no are the basic notations for switch terminals.

Domestic boiler controls are the most basic of control circuits an electrician can expect to some across, the whole system is just a couple of switches in series

Because its for central heating off which the valve/plan you have doesn't need it. Would be used on a motor open motor closed valve for example.

Because it's a Y plan system,

Point taken.

 

[sparksburnout]

Point taken.

No its OK. How can such a simple thing cause such grief? You even get a diagram. Oh well.....

Not really in series Dave as each 'half' or set of contacts are completely independent of each other.

I meant that the complete control circuit is a couple of switches in series, not the internals of the programmer. Hence saying that the whole system is just a couple of switches in series

Ok I thought we were discussing the programmer though.
