topic Error code in Nest Thermostats

Error code

Marti67 — Wed, 02 Mar 2022 17:33:15 GMT

I’ve only had this installed for a few months and it was working fine, now all I get is h71 and failed to connect. I tried several times in moving the thermostat, resetting the heat link and the thermostat and it’s still the same. I’m ready to throw the thing.

Hi there. Thanks for reaching out. What color is the light on your Heat Link?

hi, it’s a yellow/orange light. I’ve tried to re pair the link and thermostat but it still fails to connect.

Got it. While trying to reconnect them, you should see a blue light on your Heat Link. Let's try to press and hold the button on the Heat Link for longer ( 30 - 60 seconds ).

That's great. Let me know if it disconnects again. I'll leave this thread open for a couple of days.

It shouldn't disconnect anytime soon, but I'll cross my fingers for you.

unfortunately, it’s done it again. At least this time it stayed connected a bit longer lol.

Thanks for letting us know, @Marti67,

From the last messages, I've went to the conclusion that the intermittent disconnections are caused by the interference in your home. In order to be able to recognize and treat the symptoms of wireless interference, please access the following online help article and read it thoroughly: Troubleshoot wireless interference . Please let us know when you've read the article and applied the steps from it.

Hi, I’ve tried redoing it again this morning as it kept being connected then didn’t. The nest seemed to disconnect from the thermostat a lot and have a yellow/orange light but it has connected and fingers crossed, it will stay this way. Many thanks for all your help.
