Anyone good with boilers / an Electrician?
 

Not sure if im gonna get anything out of this but here goes. I have a Vokera 20/80 RS boiler for which i have just bought an analogue timer for, however despite being told it comes with instructions, the instructions said "consult the manual" which i dont have. :rolleyes:

Anyhoo, included is some shots of the wiring shematic and circuit board, and im hoping one of you lot might be able to help me.

Any ideas?

EDIT: More pitcures can be provided if necessary.

What is the make and model of the timer. There may be a wiring diagram on the net somewhere if you google for it ???

You need to be careful with anything directly fitted into boilers. Technically that should only be touched by a CORGI registered fitter.

If it was a washing machine or similar I could have helped, try this member. He is a qualified heating engineer.

I re-wired my system to incorporate a second pump via a relay - Potterton were amazingly helpful with diagrams - I cannot answer for Vokera but Here is a contact from their (temoprary) site

ok - I have the same boiler, but with a digital, rather than an analogue timer - I'm assuming the connections are the same (the wire colours are)

white/red wire - remove existing double black wire from back of timed/summer/constant switch, fit double connector onto terminal, connect red/white wire & refit original double black wire.

blue wire - connect to bottom terminal marked 'N' on main terminal strip ( marked NL123N)

white wire - connect to terminal '1' on main terminal strip.

Red/black - connect to spare terminal on back of timed/summer/constant switch.

usual disclaimers apply (not my fault if it doesn't work or blows up, basically ;) ) but I hope that makes sense. :)

Homealone, you couldnt supply a photo of the back of your board could you?

Just so that i can see it?

Re: Anyone good with boilers / an Electrician?
 

I can tomorrow - I'm having the annual service inspection, in the meantime, the diagram on the little instruction leaflet looks exactly the same as in your piccy.

only need to be corgi registered when making gas connections :)

Re: Anyone good with boilers / an Electrician?
 

Hi Homealone,
That would be great if you could, i am having difficulty understanding your instructions for the Red/White and red/black wires.

On my boiler, the double black plug goes into the bottom terminal (the "on" postion) on the Power switch, not the Timed/Summer/Const switch which you indicate.

It looks like the following:-

Power

0 (Off) - Blue Cable

Middle position - Brown Cable

1 (On) - Double Black

One Double black cable goes to the Timed/Summer/ Const Switch at position 0 (Timed) and the other goes off to the terminal strip.

I have included a diagram to make things a bit easier to see, perhaps it will help - feel free to butcher it :D

EDIT: By the way - wat do you mean by "the diagram on the little instruction leaflet" - what instruction leaflet do you mean?

Re: Anyone good with boilers / an Electrician?
 

I got a little instruction leaflet with the timer, when the boiler was first installed, I'm a bit snookered for a scanner, atm, otherwise i would put up a copy.

It sounds like they expect you to remove the connector on the timed/summer/ constant switch taking the black wire from the main on/off switch & replace it with a double connector, which then takes the red/white wire from the timer and the existing black wire, as well.

It should be a lot clearer when the engineer takes it all to bits, tomorrow, when I should be able to put up a couple of piccies and /or a diagram.

Nice one - thanks! :tu:

/wonders whether to call the Glasgow fire brigade and put them on standby :D

Re: Anyone good with boilers / an Electrician?
 

That maybe not a bad idea... :D

Re: Anyone good with boilers / an Electrician?
 

I think it's worth pointing out that the timer connections may well require voltage free contacts & that no voltages should be supplied to them.

or something like that (as it says in my manual).

I'm doing a similar job to mine soon.

p.S. just in case anyone mentions it, this IS allowed to be done by a DIYr under the new electricity in the home regulations that came into force on 010105

Re: Anyone good with boilers / an Electrician?
 

okey dokey, here's a pic of the circuit board, I hope its ok - it's hard to take a steady picture perched on one leg up a step ladder ;)

as for the 'double black' connection, it looks like my instructions were wrong, because as TBR said, that is connected to the on/off switch, not the timed/summer/constant, one. The red & white wire from the timer is attached to the same terminal as the double black wire on the on/off switch.

the red & black wire from the timer connects to the top terminal on the timed/summer/constant switch (top as in furthest away from you)

so

3
2
1

you connect to 3.

I hope that helps?

Re: Anyone good with boilers / an Electrician?
 

Hi Homealone,
Many thanks, but i just want to check one thing - the red/black wire goes into the furthest position away from you looking at it, which would put it in the switch at the constant position, correct?

Is that right - and just to make sure were both on the same track here, this should also be the position which one of the black leads from the double black plug on the on / off switch also goes too.

Again, many thanks i appreciate this.

EDIT: i ask because i would have thought it would have went into the timed position and you cant see it on the photo. ;)

EDIT 2 : Sorry my bad - talking bull.. :D

Re: Anyone good with boilers / an Electrician?
 

bum, he has just left & it is all closed up again, now.

That would be red/black wire to the constant position, yes, that was how the engineer said it was connected, anyway - he did me a little diagram which represented the terminals on the two switches like this

on/off <> time/sum/const

4 <> 3 (constant)
3 <> 2 (summer)
2 <> 1 (timed)
1 <>

the red/white wire from the timer connected to no 2 on the on/off along with the double black, and he showed the red/black lead from the timer going to no 3 on the const/sum/timed.

- I have to admit logic would suggest a timer would be connected to the timer terminal (no 1) ?????

- and I didn't get whether one of the double blacks went from the on/off to the other switch, sorry.

oh & no problem, I'm glad to try & help - I just hope I havn't confused you even more :)

ITS ALIVE!!!!!! MUHUHAHAHAHA!!!!!! :D

Rep this boy for me peeps... :tu:

Cant belive it works myself - but there you go.

Re: Anyone good with boilers / an Electrician?
 

YAY - brilliant - w00t :cool:

Re: Anyone good with boilers / an Electrician?
 

and not a mushroom cloud in sight. Well done! :D

I have been asked to present homealone with this award for this thread for all his extremely patient help in getting theblueraja sorted out with his boiler. :tu:
