Hi Looking for some advice....I have just purchased a Nest 3rd Gen and are looking to install myself. I have a Honeywell ST9400C programmer for heating and hot water positioned next to my oil fired Firebird Combi boiler. I also have a Honeywell room stat. I have photographed the existing...

Hi, I have a flexicom 18hx glow worm with a nest thermostat connected. The nest panel has gone dead so I cannot switch on the heat at the moment. Can anyone explain to me how I can manually start it and override the nest setup. Google are sending me a replacement nest but won't have it for a few...

I've had a quick look on the forum and have found similar but nothing I can see that's double cabled and with a fuse box. I think I've identified the black as C and grey as NO via the forum. Question is, what do I do with the wires from the boiler and fuse box. I'm assuming these do not go to...

Hi all, I have read several posts and searched the internet and believe I have now got the correct procedure to install a Nest for my Greenstar 30DCi classic boiler with an Integral Diverter Value with a DT20 timer. If I could just get a second opinion, before I proceed it would be really...

Hi I would like to change my current thermostats to google nest thermostats. This is my current thermostat and inside I don't know if it is relevant but my boiler is Logic Combi ESP i35 boiler and it is dual-zone. I found where are my motorised valves, however, I'm not sure what to do...

Hi. So Combi Boiler Heating type: Water Underfloor heating, Only one Zone. Nest type: Nest Thermostat E (Images For Reference) Just received the Nest Thermostat E and trying to replace it instead of the OLD Thermostat, but I am having some difficulties with connecting the underfloor heating as...

Hi All, I have got question on installation Nest Heat link to boiler. I have got Vaillant Ecotec Pro28. I currently have Honeywell thermostat and receiver (wiring) has been shown on picture attached. Should I do exactly the same as on the picture above ie: N to N L to L With yellow/ green cable...

Hi, I wired up my Nest (3rd gen) fine in my old house a few years ago, but have just moved into a new build and the heating system is WAY more complicated than the last one! We have a boiler in the garage, hot water cylinder in a cupboard upstairs, programmer in the utility room and two zones...

Hi all A new member here! I have bought a 3rd generation nest that I want to integrate with my Worcester greenstar 30dci classic boiler. The central heating control is straight forward enough but I can't find much advice on the hot water function wiring on my particular configuration. The...

Hi all, I have just moved into house which has the original 1980's thermostat on the wall. It is very worn and old, we are decorating and would like to replace this, hopefully with a Nest unit. The boiler we have is an old Glowworm Betacom 24c, installed in the loft. It is in very good, like...

Good morning, I've had a look at a few threads featuring a horstmann H37XL however the wiring on the posts is slightly different in that our box has 2 lives, earths and neutrals. Our central heating is a 2 zone controlled by Drayton ZA5 aculators, oil fired and currently using the horstmann...

I have a Nest gen 3 Gas C/H system in a standard size semi. Up until a couple of days ago, the hot water and central heating worked fine. The schedule and app on phone triggered as should. Nothing has changed in the house whatsoever. The thermostat and the Heat-Link(receiver) are paired so I...

Hi was having a look at the wiring for my boiler (baxi duo tec a 24) to see if a nest thermostat would be suitable. My currant thermostat has a mind of it own. The wiring doesn't look right to me, just popping it all in a terminal strip together. Normally my dad would have a look (he was a...

I know this is probably a dump question but just want to check. I'm thinking of getting a nest 3rd gen thermostat fitted to my Baxi duo tec 23 HE A (about 6 years old). Will it work on openthrem or just on/off ? Thanks

Hi, I plan on installing a Nest Thermostat E with Heat Link to my property however can’t seem to match up the wiring on the apps instructions. The property was built last year and has air source heating installed, I have, in the cupboard some sort of tank with a Daikin control panel. I have...

I have been spending a lot of time at home (due to the coronavirus epidemic), and I decided to take the plunge, learn something new and replaced my Danfoss TP9000 with a nest thermostat 3rd generation. After reading a lot of forum and posts online I was pretty confident that it would be easy...

I’ve recently had a nest 3rd gen thermostat installed into this boiler, seemed nifty at the time however, this replaced no previous thermostat (we used to manually switch it on and off and there’s a panel at the front with a analog timer). So the nest 3rd gen replaced this. It’s been a few...

Hi all, I have an existing Baxi EcoBlue Advance combi boiler controlled by a Nest 3rd gen via Heat Link. I’ve just installed an Omnie UFH system (wet, boiler fired) and am trying to connect up its wiring centre, with it being controlled by the same Nest (as opposed to Omnie’s own thermostat)...
