Nest thermostat / heat link

TCO

I have had so many issues with my heating over the past few weeks for example 1) radiators not coming on despite the thermostat saying the heating is on 2) will not work using the nest app and 3) heat link manual override not working etc. I have read quite a lot of posts regarding similar issues and was recommended to reset my thermostat. So I have reset the thermostat but I can’t get past the equipment stage in setup as it will not wirelessly connect to the heat link. I have tried resetting both units / turned off all WiFi & moved the thermostat closer to the heat link as suggested on the help pages but I still cannot get the two units to connect.  I have had the nest system for a few years  (3rd generation nest learning thermostat) and never had any problems until recently.

I removed the device from the app and I now can’t get it back as it wants a 7 character entry key which you can get from the thermostat via menu / settings but as I can’t connect the thermostat and the heat link I cannot finish the thermostat setup.  I have the blinking blue light on the heat link but I cannot pair the devices - I have tried the  “replace heat link" and "reset pairing", but nothing works and I keep getting the H71 error.

the only good thing following the reset is the manual heating override on the heat link is now heating the radiators but I obviously cannot control the temperature. 

Can anyone help please?

Thanks for reaching out to us here @TCO. I am sorry to hear you are having difficulties with your device and I would be happy to try and assist. First, just to check, is the thermostat mounted on a stand or did you take it off the wall and take it close to the Heat Link?
