Hancock and Brown training video on the nest, this will show you a typical ‘s’ plan wiring, combi’s will be simpler, remember these are expensive and faults can break them, so always use a competent person, as this video is aimed at helping other electrians and heating engineers
What is T1 and T2 wire doing? This is 12v. Is just a power supply to stat or actually on and off switch wires? If it is just a power supply I assuming on and off controlling over wifi connection then?
Hi thanks for the video very helpful. Just wondering if there is anyway for the pump (in my case downstairs ufh pump) to not come on when the other heat link calls for heat. Seems they will both trigger it?
I don’t know your underfloor, but some underfloor wire in daisy changing method. With 4 wires. This would make thenest not suitable. I’d stick with the underfloor stats and then a nest on the main heating. The nest can work any that’s just relies on a make and break. But if it’s data it needs. You have to use its own thermostat
Best video so far on the Uk Version off the nest thermostat Now if someone could post a video off a Grant Vortex Eco External system 21-26 Boiler and a Danfoss Controller maybe i can get mine wired up Thanks
I don't get this video. The Nest is designed to replace an existing programmer. Why not show how to install it at that location which is much more simple?
Great video. I am currently trying to work out how this would work if i had multiple thermostats. Would that require basically speaking, replacing all current thermostats with heat links and then wiring the nest thermostats from there?
Hi, i got my Nest device 3rd and when I opened my thermostat box (honeywell st699), i have one cable connected between hot water com, heating com and live. How should I do this connection in my Nest device (i was expecting only 4 cables)? Do u have any email that I can send the pics over? Appreciate your help!
looking forward to fitting on of these tomorrow with confidence as its my first go at one. These nests look amazing. I think I'll be getting one for home.
Hi Boss – just curious which area do you service, cause I could really use your service. I have Nest 3.0 and MegaFlow 250I installed but not functioning satisfactorily. I love the combination but running out of HOT water at wrong times and the heating coming up sometimes when the Thermostat claims to be on
0844 391 0999. I'd check with volkera…but I think there's to 24v wires that can be used as switching wires..keep 240v away from these..but I'd suggest a gas safe engineer to do it…a printed circuit board is expensive to replace if you get it wrong
if going to a yplan, the switching wires are still 1 and 3 to that stat..try not to think resistant..more make and break, especially if your use to thermistors..the only difference is grey is hot water not permanent live. there is not permanent live on that valve. You need to pick up a live and return to the white wire to the valve, remember if you disconnect the stat wires for feeding the new thermostat, keep away from any 240v or you will damage it
I am planning to replace an old Honeywell T6160 room stat, currently in a Y Plan layout, with a Nest but am unsure about the number of wires. I notice that the circuit diagram of the thermostat shows that two connections are made in the stat, one of which is connected via a 247k resistor but the Nest can only switch one wire. So which connection do I need to make? Good video but the music is distracting.
You need to lose the music..Not required….
Does the heatlink replace completely the existing time controller?
Did you remove the programmer from the circuit?
One of the best videos. Very helpful. Thanks for going the extra mile explaining the diagrams. Hid bless you and please do more videos.
I love this product>>>t.co/Oo6vxLo4Pe but Amazon warehouse sent me a defective one. I had to return and purchase elsewhere.

Thanks for taking time to upload video, 4 years later and still best instruction I can find on you tube. Confident to start my installation now.

Oh god STOP THAT MUSIC
I saw that 10-way junction box and my eyes just glazed over…
Aaaargh !! Music Musak !!
Cheers, Wish I still had as much time these days for videos. Hopefully more coming soon ..👍🏻

the music is annoying

Nice video, where did you get the 12v supply from please.
Great video. Has anyone ever said you look like a slimmer version of T from Salvage Hunters?

good vid
Fantastic video, very helpful thanks
Hello, Thanks for all your videos.
Can you cast your eye over this and see what you think please?

looking to turn my 1 zone system into 3 x zones with a Nest thermostat in each zone.
This is the honeywell zone switches:

And this is the Nest thermostat:

Great great video – please can you update for 3rd generation Nest i.e. Hot Water?
There a nice unit.. But mainly simple to use you,ll love it good luck
looking forward to fitting on of these tomorrow with confidence as its my first go at one. These nests look amazing. I think I'll be getting one for home.
nice tunes!
Good video….Thanks
Fantastic video. Thumbs up for uploading it 🙂

Nice video very helpful. I hear your a brummie? Means your probably near me! Come install mine please 🙂
Hi do you know how to wire a nest heat link to a vokera compact 25 he any help would be much appreciated thanks

hi fitting nest to a vokera compact 25 he just want to know how to wire from boiler to heatlink thanks
I am a little confused why you have used the wago connectors in the junction box. Can you explain the reason for this please. Thanks
that was a great video … thank you so much

great video………question! I have a potterton pro max 28he with no thermostat.
do I just remove the link and wire it in the nest box?
Thanx
