nest heatlink

Hi All I’ve seen a few posts around regarding Nest 3rd Gen Learning and wanted to install one in a rental of mine. I’m struggling to get hold of any electricians at the moment so thought I’d give it a try. I’ve watch numerous videos, and got somewhat of an understanding of the principles of...

Hi, I.m looking to add a Nest Thermostat E to my Alpha Eco Boiler. The boiler has no room stat but just a timer. My understanding is that I should leave the timer in and set it to always on. I should then remove the link connecting 1 and 2 and run instead two wires from 1 to NO/Call for heat...

Hi All, Glad to join the forum, so many experts here, well done all. Month ago I have replaced my boiler with Baxi 630 Combi (believe this is a fully Opentherm compatible boiler?), and connected with Nest 3rd generation thermostat. Installer was great, but not good with the new technology, but...

Hi all, Looking to swap out my existing Salus RT500RF with Nest 3rd Generation. Combi boiler so only heating to worry about. Nest thermostat will be talking to HeatLink wirelessly only. Looking at the current wiring [see attached] I think it’s just a straight swap, but just wanted some...

Hi everyone, So after reading the many other threads about problems with the nest, i cant find any issues which match mine. I'm pretty sure i have a Y plan system and that i have wired the Nest correctly, after wiring it in the heating and hot water all come on but the heating will not switch...

Hello All, First off - My apologies for yet another nest install post. I just dont want to get it wrong and am installing myself. No previous knowledge of boiler work but a family memeber kindly purchased us one for Christmas but I cannot afford for a specialist to do it for me. Within the...
