NEST LEARNING THERMOSTAT INSTALLATION - How To Wire

[@steverae5618]

Great upload mate, you’ve just shown me how to get my thermostat off that silly desk mount. Perfect. Many thanks

Hi Allen, when wiring open therm and removing wires from basic wiring on boiler to open therm connections do you put link back between original stat connections on terminal block at boiler?

[@k00baa]

Great video, Allen. Question- for opentherm, does the link between 2&3 on the boiler should be removed or inserted?

[@the_judge_8262]

Why aren't all videos this simple and clear to understand👍🏼 Thanks Allen

Hi Allen, I've tried to read through all comments and I can't find anyone mention about the Ideal Logic + combi, where if you are using open therm you have to reinstate the link on the room stat in the boiler wiring to get it to work.

[@peterbodi3870]

Hi Allan I would like to ask you Ive got 20 years old combo boiler Do must to install that with box link to the boiler? Ive got only 2 wires at my old thermostat My question is can it works woth that 2 wires cable ? Its got 30v i tested Or must be install that with link straight to the boiler ? Thanks Thsnks

[@fattoamanowoodwork3638]

Good afternoon good man, thank you for all your videos. Really appreciated. Would it be possible to run something pass you (paying of course) if I may? I'm quite confident but Id rather not do any mistake. I have the installation guide but I'm not sure about couple of things.

[@imranmajid1978]

Excellent video - but please can you explain what opentherm is and what boilers have them. Also, what is the benefit of using opentherm over the regular setup?

[@Ivarposthumus]

Great video. Beter then all the Nest documentation out there. Greetings from Holland!

[@IanBeattie-s8c]

Great video Allen , when the thermostat is hard wired on opentherm can you still control the boiler via the nest App?

[@AllenHart999]

yes

[@ChrisDuffy_82]

For an opentherm boiler setup, does the live and neutral going to the heat link come from the boiler, or it’s own, separate source?

[@PereiraShane]

Love your videos great to know some quality information. 👌 I want to ask you recently I got viessman 100w combi boiler and using nest smart thermostat with it. Technician said nest is not compatible with open therm. 😑 but looking at this video it is compatible. Can I ask do I need to change the wiring in the veissman boiler or can I change the wiring on nest module and then that should do ?

[@LordJasonKing]

Alan, thanks mate. Just to ask will it connect to the heatlink wireless if its wired to to t1 & t2? Having a nightmare connecting jepp getting error code n80.

[@sgttruce9996]

Thanks for the vid. Quick question; if you use the table standard; do you still need to connect the nest to the heatlink via a wire? Or does this go wireless? Because you only showed to connect the thermostat to the headlink when you put the thermostat on the wall? Thanks for the reply in advance:) Cheers!

[@stephenrobinson2086]

Hi Allen. Please can you advise me. I have always wired a boiler switched. I want to use opentherm. Do I do away with the switched connection and put a link back in the boiler before connecting the 2 core to opentherm?

[@harrybouch7907]

I have the same question and can't seem to find an answer anywhere

[@KingKustom]

Good video Alan. But how do you connect a 24V two-wire zone valve to the Heatlink? Where do you connect the two wires for the adapter? I know the “ on/ off” wires go to 2 and 3, but where do the adapter wires connect in the Heatlink? Can’t find this in the diagrams... Please help? Thanks!!

[@KingKustom]

Urban Plumbers it is the on/off switch which openes or closes the heating (to get Hot water into your system). It is switched by two wires, but it needs 24Volts via an adapter. I can’t put photos in here so can’t show you...

[@joekane23]

Clear and concise as usual Allen I’m wondering if nest would be compatible with vitodens 050 combi boiler I’ve just had one installed can’t get the supplied stat to work with it

[@hownot2mill561]

Could I connect one of these to my old Potterton Suprima 100? Thanks

[@chengambj]

Hi Allan H, Could I have outdoor weather sensor and the nest system using open therm working together or would they both conflict with each other as they both override manual temperature control. Maybe I could have nest in basic on/off mode and outdoor sensor. My combi is Viessmann 050w. Any advice would be greatly appreciated. Thanks

[@manoloyanes8206]

I noticed in your wiring you did not use the earth wire on the heat link, isn't that required?

[@misssimmi2]

Hi, I've just had a new baxi 40kw platinum boiler installed with the nest learning thermostat. It's on on/off mode and I watched your video and tried to put it on opentherm but I get a message saying couldn't detect opentherm connection. Check your settings. What am I doing wrong? Also, what would I need for it to detect outside temperature to adjust the heating accordingly in order for it to be more efficient? Thanks

[@jasushaw]

Hi Allen Just installing a 2 zone gas boiler with motorised valves. I have wired heating for standard thermostats. So from my isolater to junction box with motorised valves and a feed up to boiler. With the heat link do I wire my motorised valves into the heat link and use it as my junction instead or what way? First time using Nest stats

[@drajcoshi]

Hi mate I had a new boiler fitted in ideal vogue max combi 40. I had the boiler engineer fit the nest thermostat as well. But for some reason the thermostat can’t be used to bring the heating on. The thermostat is connected to the heat link, I am getting hot water on demand. But the radiators work if I turn nest off to go manual heating. Can you advise on what is wrong? Is it the wiring?

[@bimiuk4051]

Hey Allen Been recommended an Ideal Vogue system boiler with HIVE thermostat!! Research show that HIVE is not really that smart and say NEST is best choice. Now my worry of NEST installation is possible on the suggested boiler and if that will add additional installation fee? By the way which model of Nest do I need to go for? Also, how many thermostat will I need for my town house (two floors + ground floor). Pls advise

[@AllenHart999]

Ideals own control makes really well with the vogue

[@bimiuk4051]

@@AllenHart999 sorry you confused me here. I thought VOGUE is the model of the Ideal (being the make)?? Question is; Nest vs Hive ?

[@Sound.wave_]

My existing honeywell unit on the wall which controls the central heating has the blue brown N/L and the grey and black, so I assume I can wire just as you did. Blue in neutral, brown in live, grey in 2 and black in 3? The thing confusing me is in that the other videos I have watched the are also additionally looping the L and number 2 connector, why?

I have a wire from my thermostat going straight into boiler on LS and LR, so do i have to put this wire into heat link and on what connection then wire heat link into boiler? On ls and lr?

[@imranmajid1978]

It's worth mentioning that the thermostat can be mounted without cable connection to the heatlink, in such a scenario it's powered by the USB cable/plug included within the box.

[@AllenHart999]

Yes thats a good point, thank you for your input.

[@benson3000able]

Can I have it connect on the stand and still have it connected via opentherm

[@explorer47422]

The nest I received didn't come with a plug - like it was designed to be sent without one. I don't understand how it can be powered?

[@czondag]

@@explorer47422 i think it will be powered and send data through L1 and L2 cables to the heatlink, and the heatlink will send the orders to the heating system. If you don't connect it to the wall you have to buy a stand with usb power connector. The data in that situation will be send my mesh connection to the heatlink, Only thing i'm not sure about is what the range will be through two concrete floors which is very common in the netherlands.(europe) many times the heating system is placed on the attic.

[@ashley758747]

Great video, I’ve just had a nest installed to an Ideal Logic+ via Opentherm, when setting the radiator temperature on the boiler should this be the same as the supply temperature on the nest thermostat? Cheers

[@AllenHart999]

if you set it around 50 it will save you more money, The downside is it will take longer to heat up. Its a balance really and will depend on the property and also the heat loss. Thanks for watching.

[@TimMorley]

I have the logic plus too. If connected with openthem (as we both are) the setting on the nest for the flow temperature overrides the boiler setting. This is the same too for the hot water temperature. Setting the flow temperature on the nest at only 50 defeats the point of openthem control. (Sorry Alan!). Set this higher, on a cold start the flow temperature will be much higher for a short period and get the house temperature increased faster; as the room temperature get closer to its target the flow temperature is reduced anyway

[@maxmerton]

I'm curious that you call the area where the boiler terminal blocks are "the combustion area". What do you call the area where combustion actually takes place?

[@adrianoreilly9846]

Hi Allen When using open therm do you replace link removed earlier thank you

[@taludoka]

Thanks Allen for your video. I own an old wood boiler for heating, which was adapted to work using a pellet burner (Blaze Harmony XS26). The Pellet burner doesnt support OpenTherm, but it does support regular on/off thermostats. The Room thermostat connector on the control panel supports less than 12V. Would Nest Thermostat work for me by connecting 2 and 3 (on Heat Link) to that two wires connector? Also in this video you wire Heat Link to the Thermostat, but can those two work together wireless?

[@PilotLyons]

Hey Alan, great vid as always... I have the older logic plus, currently have the PRT 4 (or 3 not sure) can you tell me how I do the opentherm set up on this? The opentherm works really well on the PRT but wanted to upgrade to nest (as we have nest protects too)

[@bojantrafela9881]

Hi, one question: Can I install Heat Link using just TWO wires, that my current thermostat is using to power on my heat boiler (Electric Central heating). Basically, current thermostat, sends a signal when heat is needed, everything else done by the electric boiler. Thermostat is battery powered, but live wire (220V) is connected to it. This wire goes directly to my electric heater. If this is possible, which two connectors on the Heat Link should I use, and do I have to "jump" any of the connections? I know that there is a NEST E thermostat on the market which is design to replace my current thermostat, but I would like to use 3gen on my system, because it will give me wide options if I decide to change my boiler.Thank you for the answer.
