Nest Thermostat E (UK)- installation & first impressions 

Thank you for the no -nonsense video, very clear instructions, well done mate!!👍👍👍😀

I had the same terrible Honeywell as you replaced in this video, thanks to you it took me less than a minute to swap over. Thanks for the video!

Thank you for the video. I’m struggling to wire mine in. I have a Drayton thermostat with only N,L 3 (call for heat) and earth, you mentioned common but I don’t have a common wire. If I wire just the call for heat it trips the fuse on the controller in the airing cupboard.

Thanks for your video. After watching it I decided to bay nest thermostat E. In my case I can control hot water. I have Combi boiler connected to my nest by the protocol OpenTherm .

Thanks for your video.

Hi i have a drayton rts1 and it has live, neutral call for heat and earth wire which one should I connect

I have two 3rd gen already installed in my home, but one of them is in the entryway (useless) so I bought a E to put on the living room. Is possible just to remove 3rd gen from the entryway and put there the heatlink connecting only the two cables I have there? t1 and t2?

Hope you can help please. I have a nest e and Honeywell receiver. Format is NLL ABC Connected A and B as common and normally open. However it’s not working, what I’ve noticed is when switch to the left of NLL is turned of so is the boiler so do I need one of the wires from NLL to be connected also?

hello a question my boiler works with otbus thermostat do i have to connect the two wires in ot1 ot2? thanks for the help

I've watched a few of your videos and they are excellent and well explained, but I can't quite find the answer I'm looking for. I have an Ideal Logic H24 boiler with 2 zones. The downstairs zone had a mains powered controller for zone 1 and hot water and it was simple to replace the existing thermostat with the heatlink in it's place and just wire 12v across from the Heatlink to the Nest thermostat situated next to it. Upstairs zone 2 is trickier as it's battery powered and only has the COM and NO wires so no mains power, meaning I need to install the Heatlink by the boiler but the only wires available in the boiler are Live, Neutral, Earth and Switch Live 1. Everything else comes off the back of that and disappears into a circuitboard. I can't therefore locate the other end of the COM and NO that I have upstairs to wire into the 12v of the Heatlink and there's no obvious zone 2 COM and NO to wire into the heatlink either....

Hi I have a Honeywell T63 in my hallway already connected to my combi. Are you saying I can just take that off and connect the Nest E to it? Then just plug the display in my living room? No boiler wiring? I am confused.

Mine is Honeywell and it's got live wire, neutral wire and one black wire connected to A, but no (NO) wire what should I do as I can only connect common wire?

Hey really handy video, helped with the install, thanks. I have the 3rd generation nest installed to manage hot water and the downstairs zone in my house. This has taken over the programmer for these functions (Same eft one as in your video just with 3 zones) . I am installing the nest e upstairs replacing the thermostat there, do I still need to keep the programmer downstairs to have zone 2 always on or is there a way around this?

Is there a temperature sensor in both the stand and the heat link?

Hi, quick question, will the smart thermostat work with the Ideal i-mini 24?

Great video, very helpful but you mentioned that both units have a temperature sensor. Which one is used to measure the room temperature? Can you select the one that you want to use?

Thanks for the video, I don’t seem to have a common wire? I have a Drayton rts1 thermostat, this has a live, neutral, earth, and call wires. So the call goes into NO, does that mean the earth is the common wire. Can you help, thanks

Hi, great video, in fact not many out there for the E model. I have few questions, I have a Vailant Ecotech Plus 832 with a Blue (N), Brown (L), Grey (into A) and Black (going into B). Do I need to do anything with the Blue and Black? Looking at your Video you suggest the Live and Netural are not required. Any ideas how I should wire mine? Thanks

Hi my fuse blew off after I connected my ideal logic plus 30 with common and No correctly but upon startup my switch fuse 3 amps blew off so I had to replace back my old thermostat Salus back again with new fuse . I had terminated my live and neutral and earth into the terminals but I’m not sure why it happened. Any clues please ? The combi boiler is 230v with 3amps fuse . Thanks in advance as I’ll give it a go again .

Great video :) Do you know if the thermostat e can also be used to signal a 2 port valve to open two, e.g. is using it on an s plan system to control radiators (and ufh in the other separate zone). The valves have way more wires than just the two needed by the thermostat e heatlink??

How they communicate with each other via bluetooth or wifi?

"So you get 2 thermostats for the price of... 5" hahaha

Can you explain where A and B go on the actual boiler electrical box?

Just about to buy a Nest E - I think I'm right in assuming that my very recent boiler installation in our loft with an EPH wireless thermostat will be super easy to replace with a Nest and the boiler being in the loft won't be an issue with the Nest?

Hello!!! I have 3 zones in my house, each with an Anwo ATP-1 thermostat. When installing the Google Nest E (UK) the on and off works but does not separate the zones. For example, turning on zone 1 heats up the other two zones. The problem is that when you turn off the thermostat, it does not close the valve, so when you turn on another zone, it heats up in the same way. Can you help me?

Hey, great video. But, how do i remove the thermostat e from the base to mount on the wall?

Hi I have a Honeywell and want to replace but having trouble identifying the correct wires my reciver is wired with Blue in N Brown in L then a link wire from a 2nd L terminal next to the brown wire to A and finally grey wire into B Amy ideas on what to do would be greatly appreciated thanks

I have a honeywell c21 under my boiler and a wired thermostat in the hall. On the c21 it has N, L, 1, 3 and 4 wired. Any idea which ones are common and NO and whether I need to do anything with the wired thermostat? Thanks

Hello, I have a google nest e thermostat like you have, but I have a problem with connection, I do not know where to connect these 2 cables to the vaillant boiler

Hello, I have a vaillant home regular15 boiler with separate hot water tank! I also have 1 programmer (next to the boiler) and 2 thermostats 1 downstairs and 1 upstairs. What would be my setup process?? I'm guessing keep the current programmer and but 2 nest E thermostats?? Please help 😁

So receiver powered by batteries ? Do you think it ll be an issue when customer have to change the batteries? Will it a notification on the app?

I'm not finding the rewiring that simple, have you got any idea how to rewire a Vaillant ecotec pro 28 ?

I’m struggling to wire mine up I have a Honeywell cms921b1042 at the moment and not sure which way to wire it up ... thanks

So the 2 cables you need from your existing room stat is a permanent live and a switched live ? Thanks

Hi, do you know how that thermostat can be wall mounted and not on the stand? Great video 😁

I don't have an existing thermostat just a controller. Can I just replace the controller with the Nest E ?

Hi, is the heat link powered by the cable’s? Or only by the batteries?

I have a problem with the installation, every time I connect NEST THERMOSTAT E it burns, the fuses. My current thermostat is Danfoss TPOon-RF 087N785300 with new combi boiler WORCESTER 1Y old

What size of 2 core flex would I use, 1mm?

Still not convinced it's better than Nest Gen 3, the look is "plasticky cheap", there's no learning capabilities, the heat link having fabric seems less than ideal to be closer to a boiler that is installed in a kitchen or basement subject to "dirtyish" environments. What do you think?

Will this work on an oil burner

is it just me or did you connect the neutral and the call for heat on the Nest the wrong way around.....?

Why can I not install the 3rd generation same way as the E. meaning, why can’t I just install the 3rd gen heat link in place of old thermostat rather than fiddling with boiler cables.

Isn’t the nest e thermostat a wall mounted thermostat?

Followed the instructions discussed few months ago. Terminated = N and L Connected A to C Connected B to No The above blows the fuse? Tried this with a 3A and 13A fuse blown both times. Any advise?

Can the heat link be wired as oppose to batteries

My boiler is in the outside shed. I don't really want to put the heatlink outside where there WiFi transfer is. Any ideas. Can I not connect the thermostat to the existing WiFi link?

If I was to get a professional to install the normal nest, who do I call? Electrician or a gas technician?

I am having a nightmare with this Google Nest E thermostat. 5 days of trying to get it to come on at 7:30am and go off at 10pm. I have programmed, reprogrammed, reset, deleted, reinstalled, read and read and read forums and communities and help and support. the schedule says on the thermostat and on my app that at 7:30am this morning it should be 22 degrees until 10pm tonight when it reduces to 15 degrees. Its now 10:29 am the my apartment is 19 degrees! Can't get help, support from Google. Can't get my money back.

Hi dear,any new video from Nest Thermostat E (UK) - review after 2-3 Weeks of Usage ?

Mind you cannot complete setup using Google Pixel phones, try any other Android phone instead.

All those exposed cables dangling around would drive me mad.

So this video does not show the important steps of adding the heat link and connecting the Thermostat E. What a waste of time. I was forced to buy a new Nest Thermostat E, because the wifi stopped working on the original one. It is still under warranty but I don't know where it was bought from and the plumber does not want to know - he's been paid. I think it will be much easier to go back to having an old fashioned timer. At least that works.
