You are a star! Thank you so so much for sticking with me ...

One last question! I see there are wireless controllers available do you know if there is one that would fit my boiler so I could control it from inside the house rather than having to go out to the garage every time I want to, say advance the heating or am I better just to buy the original programmer for that boiler? The original ones are not cheap! £150!

Thanks again for all your help

My solution would be to mount a programmer near to the boiler and connect it with a 5 core H/R flex.
£ 60 tops for gear . You could add a RF room stat if you do not have one!

So just any boiler programmer will do the job? Drayton Lifestyle LP522 5/2 Day Electronic Programmer £45??
Then just wire it up ..

Yes that's exactly what I use.
Just wire to X4 plug instead of existing.
