Well that didn't work so I gave up. I used a USB cable to power it and mounted it to the wall above the plug. Will get some trunking tomorrow to hide the cable and all sorted.
Thank you all for your help in this.

Yes you are right i did do that.
I didnt really have time to test it last night but i will do it over the weekend. I dont have a multimeter but i do have an electricians screwdriver (the one that is insulated and lights up if you touch a live wire).
I will leave things plugged in and power...
@muggles yes understand that....im just trying to make sure i have the correct wires. I dont want to go back to where i was a few weeks ago.
I also understand that i could get an engineer in to do this but i dont have the spare £100 call out fee...you guys on here are being a really big help...
OK, to me that sort of doesnt make sense, if the wires i removed from the boiler Tr/Tl terminals are the same wires connected to the drayton on the wall (grey and black) that would mean im connecting a Neutral and Switched Live to the Nest????
OK when i look at that pic of the boiler all 4 of...
Is there a way for me to test them?
Also looking at this pic of my Drayton header unit which 2 wires do i connect?
On the boiler i disconnected a grey and black wire, so on the drayton i will assume i connect the N and the 3 wire as they are the same colour.
apologies about all these...
OK i think i just had a light bulb moment....
That picture that i posted above was taken after i wired the Heat Link to the boiler. I removed 2 wires from the room stat (Tr and Tl) and secured them away. I then put that link in between them as i was copying a pic from earlier in the post...
Stem,
thanks for the above, fully understand. Muggles told me what wires to connect the the Nest header unit i just need to find the other end and connect them to the T1/T2 terminals, but have no idea how to trace them back.....uuugh DIY is hard....
Stem,
1st point, I have the Potterton Powermax HE 115
2nd point, yes its all working fine, but i have to have the nest sat on the side powered by a USB phone charger. I want it where the old drayton thermostat was, on the wall.
by the sounds of it i will have to remove the drayton...
yea i was just out running and i find running clears my head and i get some good thinking time, i thought that might be the case. so its a matter of finding where those cables that were connected to the old Drayton are plugged into and connect them to the T1 and T2 sockets in the heat link. That...
The problem was the older Drayton Unit. I managed to get hold of another Drayton Unit and it worked fine, but putting the original unit back on it popped a fuse again. that's why, after doing hundreds of other projects, i was confident to come back to this job.
Anyway, I have wired up the Heat...
I never got an electrician in. I have read the manual many times and looked at these pics here and have wired the heat sink up to the boiler. That worked. I then connected the thermostat to a USB charger and it all works.
All I have to do now is find the 2 brown/black wires at the boiler end...
hi Muggles, Im ready to try again with my Nest and the Powermax. Im confident with the Nest heat link box connections, but still a bit confused with the thermostat end. Based on the picture i put up thats connected to the Drayton thermostat on page 4, what out of the 4 cables (Yellow Earth...
Oh yea baby, over the moon :)
There us a further issue. Got it all working then turned the dial in Drayton thermo controller thingy on the wall and it soarked and popped a fuse in the boiler again. Luckily it only popped 1 fuse and I had a spare so it's working again but I'm not turning the...
