PB Plumber Nest Thermostat on a Y Plan 

the best y plan video on the net... first class

The best video I've seen on this subject

Really clear and super helpful, thanks for taking the time to put this together.

Perfect. Nice, simple and easy to follow. Especially if you have an old heating system. Key is to start from the three port valve wiring, as mentioned on the video

*Works great: **Fastly.Cool** and Warming environment perfectly controlled. I use 3 in different grow tents. It’s nice to see from your phone how your tent temps are. Does High and Low and records data.*

Excellent video mate I never thought I’d say that about a plumber making sparky videos 🤣

I followed your video months ago when I went to fit mine. As I was having other work done I just asked the electrician to do it. I ended up explaining to him how to do it using your video after he messed around for a couple of hours. I know at the start he thought I was one of those pain in the butt customers, at the end he had to give me (you) a lot of credit. Thank you.

Av just found your channel sir,and av most definetly subbed am an electrician myself by trade,and am called upon occasion by freinds to fix their systems,, I have to ssy sir,, You have made an absolutelly brilliant video, superbly filmed,and spoken very clear with clarity ,and abov all easy to understand,really well done sir,

Wired my first one today. Wiring not my strong point, but your video made it straightforward. Thanks for all your efforts 👍

thank you for your time, I am a heating service engineer that carry out up dates of heating components and wire up my own heating equipment, trying to explain in such a easy way is hard as it is you have hit the nail on the head. NICE ONE PB

Evening PB Plumber, very impressed with the way you have explained how to fit this onto a Y-Plan system, hope you and your family are all well :)

i think i have a job to fit a nest onto and old ideal mexico probably y plan so this vid is just brilliant mate .... by the way i bought the velocity pb 9 service bag and it does the job perfect. Remind me also to upload a pic of my plumbing bag using inch and a quarter waste glue gunned together to seperate everything .. I think youll find it genius !!

using the 3-port valve wiring for reference is genius - thank you....

thank you for this good man, really appreciate it. Love the 'i'm not unboxing as you now how to unbox something', thank you for that too. Video is great, very clear and great explanation, great logic!

Agree with a lot of of comments, before I start fault finding, replacement or additions I rewire. The more complicated the system the better! Great vid mate.

I have spent a day and a half looking for this information, and failing, in order to decide whether to go with Hive or Nest (I'm a retired electrical engineer/registered installer) and until I fount your video I had failed THANKS VERY MUCH ! I'm now going to go with Nest.

Well explained 👍

What a brilliant information so easy to understand

Great to have a midweek PB plumbing video! Sunday comes around to slowly.

Great video, very helpful…thanks for sharing!

Thank you so much for this video! It's gone midnight and I'd struggled for hours getting ours working, your video had me sorted in under an hour starting again from scratch. Legend!

Well explained wiring for nest thermostat. You made it look simple .

Top video - I normally rewire them from scratch if I can - you should be a lecturer when you retire off the tools - great teacher

These videos are top class , the way you explain things is proper easy to understand

I think I’m going to watch this a few times before I even think about doing it many thanks pb

Definitely my favourite upload so far PB,thank you for sharing you a legend 👌

Very well explained. Any ‘control panel’ can look overwhelming in overview at first glance and you just have to suppress the panic and apply the same sort of logic you demonstrated here.

I have worked with a lot of electricians who won’t touch heating systems which is absolutely bizarre but I feel like if they take the time to understand what the components of the heating system are and how they should work together it makes it far easier to break down and install correctly

I serviced a boiler for someone last week and asked them for the magna clean spanner but they’d lost it but he said he’s got something that will do it and gave me some oil pump pliers which worked a treat so I got some off Amazon and they’re quality👌👌 they will open any filter with a top like that👍👍 only £8 well worth it

Another brilliant video with so much informations. I can’t thank you enough for making life so much easier for beginners .

A mid week how to and a Sunday jobbing vid. Love it mate. Keep it up

Excellent video you went through the theory and then demonstrate real life thank you

Installed mine myself today thanks to your easy to follow video,, it’s absolutely brilliant mate can’t thank you enough!

Great effort, not an easy thing to explain/demonstrate. I love wiring jobs too. A good tip for anyone trying to trace what a wire is in a junction box etc is to link it to an earth(with power off obviously) at one end and use your multimeter at the other end. Go between earth and all the wires till you get continuity. 👍

Great vid Pete. Wiring still baffles me after 25 years but if I watch this about 100 times I might get a bit better, my electrician tells me every time but it's gone out my head in seconds. Well done to you for taking the time to do these things, you should be very proud of it.

Really top video PB. More and more of these are being installed now so really helps. Thank You

I did my own & fitted mine where the original programmer was & run 2 single cables down from the control centre box to the nest hub, bit fiddly to get cables down original trunking but worked out well. The 2 cables were for the hard wired thermostat!, which I isolated the cables from the old stat which wasn’t needed.

Good clear instructions on the switch over, takes some of the mystery out of the wiring centre in the airing cupboard .👍

Great video! Wiring always stresses me right out!

Another quality video thanks for taking the time to break it down

Love your videos keep them coming PB 😊👍

You sir are a legend really appreciate you taking the time out to help us out 👍🏻

Very informative Pete, well thought out and presented video. This will definitely help a lot of people out. 🙏🏼

Brilliant video mate - just the right level of explanation. I've only used Hives for Smart controls so far but this has simplified Nests in my mind 👍🏻

Keep the videos up Pete really enjoying them I’ve learnt a lot from your videos your dad has taught you well mate

Brilliant video mate! You certainly know your job well! Glad I'm subscribed

Great video, good clear diagrams and real world example 👌

Happy birthday pb

Brilliant pb, very informative as always. Not always but usually my older clients enjoy simple adjustment with off and on. My Italian barber told me years ago that when pay and display coin payment parking went over to credit card only payment, he lost all but one of his older clients.

Quality video mate! This really helps!

Great tips on identifying the cables like you ive seen many a “live” earth coloured conductor solid practical advice really rate it !! I once had an solan crammed into a one gang plastic surface box you really do see all sorts and simplifying it like this is definitely the at to go well done !

Great video, well done

Top video mate. 👍

Great video. Thanks PB

Quality vid mate, nice one! 👍🏽

I’m the same, love a test on heating wiring. Had to convert a flowshare RB2 relay unit to a y plan the other day. It was also originally wired wrong which made it interesting. Top work keep it up 👍🏻

Nice one and this also qualifies for the Gov's Green Home Grants scheme as a Secondary measure ..

You are a very intelligent (person, plumber) 👌

Class video again mate ! 👏🏻

Great video as always pb

I like the way you break things down top video

Many thanks ❤

I nearly always rewire them, does my head in looking at this type of wiring.

Great video, Pete! I would prefer to work with someone a few times to get some real hands on experience. I tried to install a Nest at my house with a Y plan but gave up. I installed a Hive instead

Thanks genius Another great video Wishing you a very happy birthday mate Apologize for late wishing

PDHW next peters

Very well done video 👍🤓👍

Great video PB, I've done a couple of Nest installs on S-plan but yet to do one on Y-plan 👍🏽

Classy 👏👏👏

Really good video again will have to watch this a few times I think. can be so confusing working things out when you open up the rats nest of wires 😭

The way I do it is to use the zone valve (s) colours as my reference point. If you memorise the colours and what they do and where they go. You can plot it out and can’t really go far wrong.

It would appear congratulations are in order ! Happy birthday. Where is your cup of tea link ?? Can't send you money without it 😉

Like and saved cheers 🍻👍

Hi pb I dun so many Nest it's a great

Really good, I have bookmarked so can direct others to your video, my system is C plan, I could find plumbers and central heating engineers to plumb in extra zone valves, but non seemed to know how to wire. So I had to work it out myself, lucky I am an electrical engineer so easy enough for me, but not even a nest example. The DHW com goes to boiler which is unusual wonder if you have done a video for that?

Got caught out with the legionnaires setting on my 1st one. Thought I had a faulty nest

Good video

Thanks - unfortunately it didn't help me a great deal since my system didn't have a wiring centre. Everything was wired into the programmer. So I had a much more involved task of retro-installing a wiring centre then wiring the Nest into that. I also had different wiring colours for the three-way valve. Got it working in the end though but it took quite a few hours.

Great video, can you do a s plan one same way? Appreciate it

Great vid Paul . I remember my first wiring centre. I found that knowing how to bell out using the earth is a great way of identifying cables. Which nest was that you fitted.?

its not sunday!? :p great video as always

Very nice video but please can you do S plan video

Such a great video and thank you. Quick question, I have a Vaillant boiler but it has a Vaillant Control Centre box in the airing cupboard. Can I still follow the same S Plan wiring ? Many thanks

You normally don't have a permanent feed at the wiring centre , if the switch fused spur is next to the old timer you can link out the cables to get a permanent supply up to the wiring centre

Which do you think is best for a combi boiler. Between the nest and the hive.

That’s why the 3-port gets a junction box 😂

This was an excellent guide. I managed to get NEST installed. I have one issue possibly you can point me out to the right direction & really appreciate.When I swicth on Hot water only my three port valve move to mid position. It looks like it is trying to move to Hotwater only position but making a ticking noise (looks like it tries to go back & forth) & stay in the middle. So when I switch on Hotwater it also heat up the Radiators (becase of the mid position). Valve itself looks working because for an example when I complete power off the system the Valve move to the hot water only position as the default position, so I can see its not stuck or anything. I think some sort of electrical wiring mixed up it seems.Also Heating only works without an issue (Valve moves to heating only). Thank you in advance

Nice!! Opentherm is the next step. What boiler was this on?

Great video PB, can you connect a Yplan to open therm?

S plan next mate ;)

I'm stuk with a 6 colour switchmaster what about thst one there's a spare red after the orenge has been put im

Ive taken loads of those nests out, mainly from customers on contract with BG being talked in to them without a real need then finding ‘the bloody heating used to be great, warm within 20 mins, now it does what it wants’ etc.

I have followed your video seemed easy but the heating will not turn down, my pump is wired in with blue from zone valve also a neutral and neutral from pump. And orange from zone valve also a live and live from pump is this maybe the problem any help appreciated.

Has anyone noticed, for years Nest and then Google got the wiring diagram wrong in their booklet re the cylinder stat?

Did my friends hive on an s plan 3 hrs later and a nervous breakdown and sparks on the phone i did it

What’s that app mate on your iPad

Nest really should have implemented a cylinder probe for dhw temp

I want to buy a new thermostat that works by phone But unfortunately I do not know which type to buy, and unfortunately the video did not help me, because the heating system in Holland is completely different, the system I have is through hot water, there is no gas How can you help me?

What about the boiler control on the orange from the 3port

Worst wiring centre I’ve ever seen was a load of connector blocks in the floor with the plastic you over you get from the end of a bundle of pipe as the over with a 2 inch 10 screwed into the floor board 😂
