Nooooooooooooooooooooooooooooooooooooooooooooo, keep an electrician away from it, they normally cock heating systems up bad 
post us a pic of the boiler wiring diagram for us anyway just for fun, s plans are normally straighforward as far as the boiler is conerned, orange is the boiler SWlive, then if the boiler has a permanent live one of them then a live out feed to the pump and N&E as normal, mind you I must admit that the diagram on my Isar makes you bozz eyed and yet in reality it's a simple setup.

wired it all up, called for hot water- few seconds for zone valve to open water starts to flow, im thinking yes nearly there. boiler powers up. Fan starts , no ignition. Tried the same with -CH zone valve opens, water begins to flow boiler kicks in fan starts no ignition.
So i swear a bit , if a cat had been near it would have got it, think to meself wiring ok, must be something worng with boiler, go through fault finding and appears to be APS. I remove a hose blow into it, the switch makes and we have a spark and boiler fires.. Replace hose and wont work. I think the venturi may be blocked.
Then to top of it off put the cover on the terminal block, recheck HW nad central heating, and the boiler now wont ccome on. Looks like a loose wire in terminal block. By this time it was 6 o'clock so called it a day.
And to top even that, when i was checking for voltages at thermosat connections etc me mulitmeter probes broke.
I had heard of things going pear shaped but this takes the biscuit,.
Going back tomorro to recheck me wiring and try to unblock venturi. If i cant looks like a \service call as i dont want to do to much digging around and invalidate there warranty.

You can get this with all boilers but I tend not to use stuff from sheds as it's normally made by cheapo boiler companies.
