Bonjour, aujourd'hui mon heat link reste éteint,  impossible de faire fonctionner 

Apparemment problème connu ! Google prends en charge ce défaut ?

Hi DenisB79,

I understand the frustration with your Nest thermostat not turning on the heat link, but I am here to help! Here are some steps to troubleshoot:

1. Reduce interference: Move the thermostat closer to the Heat Link and turn off any nearby Wi-Fi devices.
2. Reset the Heat Link: Press and hold the button on the Heat Link for 25 seconds twice. You should see a slowly blinking LED after.
3. Retry options after H71 message: Go through all the options you receive after the H71 message.
4. Restart the thermostat: Press the display for 10 seconds to restart.

Wired Connection:

If you want to temporarily use a wired connection for setup:

• Use a single-core wire with a maximum diameter of 2mm.
• Connect the thermostat and Heat Link using the T1 and T2 terminals. This carries 12V DC, so no heavy cables are needed.
• With the thermostat connected over wires:
  • Perform a factory reset.
  • Go through the setup and ensure both wired and wireless connections are established.
  • Remove the wired connection.
• Important: Always turn off power when working with the Heat Link wiring.

Let me know if you have any questions.

Best regards, 

Chris

Mmmmm, not to sure the below answer is really answering your question!

Are you saying there are no lights on the Heat Link, but you have power to the Heat Link?

Bonjour,  c'est exactement ça !

Même branché le heat link n'a pas de voyant allumé

OK understood, in which case so long as you have tested ALL power to the Heat Link, then you most likely have the component problem. Does Google do anything about that, well who knows but you need a Mod to help you further.

The first question I would ask is how old is the thermostat?

Acheté en Mars 2022

 Would be better conversing in English if you want answers! I assume you are in France???

That makes your thermostat over 2 years old, Googles warranty is 2 years, BUT where are you located?

[DenisB79]

Exactly

Did you purchase from a retailer or from Google direct?
