Hi, thanks to this video I successfully upgraded my Potterton ep2000 to a nest thermostat. This video is was 100% helpful and I could not completed the job without it! Thanks again!
Great video, I installed my nest today on my Y system following your guide (with a little help from a multi meter) and am pleased as punch. Next project disconnect the old thermostat as I've just set it to max for now. Cheers!
Really good vid. I have the 2001 programmer. I noticed on mine the live was jumped to the L port from the earth block with what I guess were the live return wires running to other parts, so I gave up! Moving to a new house soon with a opentherm combi, think I’ll just wait until then.
Not sure this fully works? Please educate me! This solution does not hold grey at 240 when HW is off. Ie Nest not calling HW. As grey is not energised, orange will not come on when CH white is calling at 240. Therefore you need to wire nest satisfied terminal to Grey to ensure CH works when HW off - comments?
Video was really help full gone back to it many times on jobs when changing old controls for the nest. But only just notice how bad of an Y plan heating system diagram you used. 🤔😂 Where you download that lol.. Why 4 down stairs drops 🤪 Its probably what they are showing at these skilled trade course. Anyway thanks for the video it's the best on here its helped a lot 👍🏼
Hello many thanks for the video extremely helpful. I have a question, my system is the same as the one you show. However, on my old terminals I have a blue wire going into 5. You do not mention where this T5 connection would link into? Could you help?
Amazing video. I have the same boiler looking however have nest v2 and looking to upgrade to v3 for both hot water and heating. Do you have a video/wiring instructions on how to use the junction box near the water tank to connect the heat link. Many thanks in advance
Junction box is a spiders web. You'll have to do some tracing. See my other video for a basic understanding of how you can decipher what wires do what ..
Great video and helped explain how to cable up from old programmer (i have a Drayton LP522). Question though, where did you put your actual nest device? Did you walk mount it somewhere else? I want to replace the current thermostat with a fixed nest unit so I can disconnect the 3 cbles from the Junction box and reuse them for the 12v nest power via the T1 T2 and just tape the 3rd wire. Is this OK to do?
The chances are those 3 wires in the old thermostat are not 12v at all, and if you try it, it will fry your thermostat. I have connected it via USB on a stand in my living room, as the hallway can be colder than my room, therefore it's more representative of the actual temperature I want.
@@laymandiy I just removed those wires from my main 8 port block and extended them to t1/2 on the actual nest. That then turns the 240v to 12v. Have marked up inside 12v at nest side. All working great now and not had to move the nest... Just fits into the old room thermostat location.
Hi, thanks for a great video. We have installed as directed but the hot water is stuck on. Any ideas what might be causing that? Central heating is working fine. The only difference to your video was a blue wire terminated in the spare slots but I can't see far enough to see what it could be from.
Hello, thanks for the video. How did you tidy up the dual gang hole where the old programmer was? Did you mount the heat link straight over the top, or off to one side or something? I have a one gang 'hole' but not sure how to blank it off and still have two cables sticking out? Thanks
I bought a blanking plate for 25p from local DIY store. Snapped the bottom off enough to allow wires through, then mounted the nest on the plate itself. So it looks pretty clean.
@@laymandiy Thanks for the swift reply! I hadn't considered mounting the heatlink to the blanking plate, I was going to just mount it next to it. I bought a blanking plate earlier today so I'll give this a go. I'll probably just stick it to it 🙂 Cheers
Hi, I'm so confunse about all the nest installation videos, they look quite complex. But the instructions that come with the device are quite simple, remove the old thermostat and plugin 4 cables. I dont say yours is wrong, bit I dont understand why that difference. Is it because their instructions are only for heating? Or why? Thanks in advance for your help
Normal circumstances yes it should be that simple. Unfortunately the problem comes from deciphering which cables represent the 4 cables in the nest diagram. That's the only hard bit and maybe dealing with electricians wiring it in their custom ways. The old programmer is used to work out which cables do what.
Hi, after connecting the nest replacing my old potterton, the hot water doesn't work automatically. However when I switch to manual mode it heats up the hot water. Secondly, are you able to control HW through the app/thermostat? Thanks for the patience. BW Liju
What you mean, hit water doesn't work automatically? It only works on timer and manual and it looks like manual is working? Yes you should be able to control hot water on/off through the app
Jozef Cerven the key bit it's to get everything connected to terminals where it controls on off, that will never change between the programmer, as long as it is working as intended from before hand. Simply follow the table and connect everything going into that terminal into the same terminal for nest
Title of video indicated a Y plan system, system diagram showed Y plan layout complete with 3 port valve. But NO sign of a connection to HW off terminal in original programmer and no description of a HW off connection on heat link. Very poor video.
If you do not understand why it is that the existing system didn't have hw off and it's meaning on the heatlink, please let some else who understands install the system, because that is the basics of a circuit.
@@laymandiy The circuit diagram in the install booklet (page 23) shows a HW off connection to terminal 4 of the heat link and it's vital for the correct operation of the system
We leave it on if that is what you mean and I can turn it off on the programmer I also have another wire going into number 3 also not sure what this is many thanks

You’re a star - this video saved me having weekend without heating. Great quality video. Thank you

Best video for this on the net.. very thorough and clear👍👍👍
what a fantastic video! Thank you for your efforts in this, you explained everything so well :)
Excellent video, thanks, we had the same programmer so helped massively
Amazing video. Clear and precise.
Thanks. Have the same setup. Helped alot.

5 is at least in my video wired to live. When the programmer kicks in, it makes a circuit with 4 to demand CH. Is t5 live with heating off?
Amazing video. I have a question regarding the decommission. How do you wire the display from the receiver installed next to the boiler?
Very open question. Difficult to say without knowing it's function model etc

Is there a blanking plate you can buy to put over old program base? Thanks for video.
Just your standard 2 port blanking plate, you can pick those up for 99p. You may have to pinch a hole at the bottom.

In case anyone else had the same I found it settled in but initially on return of power the system was slow to respond. Seems fine now.
I've just installed and have the same issue. Did it start responding after awhile? I've just set it up but the hot water seems to remain on

Hi. I have same heating system but my wiring in programmer is little bit different .can you help me

Simply follow the table and connect everything going into that terminal into the same terminal for nest
Great video , I assume you used the nest stat as plus and go, rather than running two wires to the nest and hub
My nest thermostat is working with a direct connection to mains and not to the hub it self
Title of video indicated a Y plan system, system diagram showed Y plan layout complete with 3 port valve. But NO sign of a connection to HW off terminal in original programmer and no description of a HW
off connection on heat link. Very poor video.
If you do not understand why it is that the existing system didn't have hw off and it's meaning on the heatlink, please let some else who understands install the system, because that is the basics of a circuit.
@@laymandiy The circuit diagram in the install booklet (page 23) shows a HW off connection to terminal 4 of the heat link and it's vital for the correct operation of the system
Excellent video I got a question before I swap it out I noticed my live cable that runs from my thermostat to number 4 is that correct
On your old potterton?
@@laymandiy yes sorry
Yes that is on my old potterton
Rather weird, is your hot water always on?
We leave it on if that is what you mean and I can turn it off on the programmer I also have another wire going into number 3 also not sure what this is many thanks
