heat link

Hi We recently bought a new home that already had a Nest heat link and thermostat, which we have taken on. Everything was working well and the system had learnt our schedule, giving us heating and hot water at certain times of the day. Due to a kitchen refurbishment, we needed to move the heat...

Hi, I’ve read multiple posts about installing the Nest Heat Link to the Honeywell Smartfit. However I seem to be struggling on how to physically wire it up. The attached photo is how the smartfit is wired up currently with everything working. Can anyone offer some advice and guidance on how...

UPDATE: Now resolved this myself, thanks to earlier post by Muggles. I just forgot to put the additional live connections to T2 and T5. Silly mistake on my part but all working fine now. Hello I’ve just bought a Google Nest Learning Thermostat v3 to replace our old setup. Sorry, I know there...

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)...

Hi all, My WB 30i combi obviously provides DHW on demand at all times when a tap is opened. It has a preheat function to provide a small amount of pre-heated water to reduce DHW heating times - manual control is via the ECO/PREHEAT button. It also has a (usually linked) input to presumably...

Hi All. Apologies if this is a repeated question - I have tried to find an answer on several forums including this one, but none of the threads quite match the wiring diagram I have. This is my current set up: https://imgur.com/a/4Ao0B1P with the Honeywell BDR91 thermostat. If I had to...

Hi all! I recently purchased a nest thermostat to accompany my gloworm ultimate 30c combi boiler. I originally wired the heat link to the drawing supplied with the instructions supplied with the nest but that didn’t seem to work and my boiler would only turn on once I went past the set limit...

Rolling up sleeves and installing the Nest thermostat we treated ourselves to for Christmas. Attached some screenshots of previous and new wiring to check before switching it back on. Anyone able to cast an eagle eye over these to make sure looks right? Black wire is boiler and White wire is...

Hello, I'm after a little help on wiring a heat link into a Baxi Duo Tec 33 Combi boiler please.. There is a wireless Salus RT501RF RF (XL) installed at the minute. Removing that is simple, it's figuring out the call for heat terminal that I'm struggling with! I'll and attach photos of the...

Hi all, Just some advise on how to connect the nest 3rd Gen heat link to my vaillant ecotec plus 831 boiler. Would I remove the jumper/link between 3 & 4. connect number 3 on boiler to Heatlink L and a jumper/link to 2 on Heatlink also. connect number 4 on boiler to Heatlink 3. connect number...

Hi all, I think this is be a fairly simple job but just want to make sure I'm doing what I think I should before I go ahead with it. I need to install a wireless Nest thermostat (so not connected directly to the boiler). I have a Baxi Duo-Tec 28 HE a combi. Currently I have a Salus wireless...

I'm in the process of upgrading the controls of my heating system. (Unvented S plan with 2 heating zones) So far I have swapped the old fashioned room stat for a nest/heat link to control the zone valve for the upstairs zone which is a trad radiator system. That all works BRILLIANTLY! So the...

Hi All, I made a post a few days ago about how to wire my Nest 3rd Gen Heat Link. User jackthom kindly replied and everything seemed great. However I've noticed that the Heat Link isn't turning on the hot water. The central heating work fine. The original wiring of the programmer was...

Hiya, I'm just getting ready for a bit of Sunday DIY but thought I would quickly check the wiring. This forum has been brilliant in getting me up to speed, but nothing wrong with a little confirmation from my peers! So... I think I've established that I can replace the Integral Timer in my...

Hi I'm a newbee, looking to install a Nest thermostat in place of the current manual room thermostat and was after a little information and clarification before I start. I currently have a wall mounted mechanical Horstmann HRT3 thermostat which has x2 wires (which measure 12V on a meter) 1x Red...

Hi everyone, I'm new to the forum but I've been reading it for quite a while and I thought I would register today as I was looking to get some help on a problem and I couldn't find the solution online. I recently purchased a Nest thermostat (2nd gen), and I wanted to wire it up to the boiler...
