Factory Reset without Heatlink

onvt — Sat, 09 Apr 2022 17:19:25 GMT

Hello,

I am trying to reset my Nest to factory settings without a connection to my heatlink.

When I try to do so, my Nest is asking me very quickly to fix the connection to my heatlink... that I do not have for now.

Is there a way to bypass the heatlink connection to perform a factory reset?

Thanks.

Hi @onvt,

Thanks for reaching out. Can you please let me know which Nest thermostat you are using (Nest Learning Thermostat or Nest Thermostat E)?

Nest Learning Thermostat.

Thanks.

Thanks for letting me know. How do you try to perform the factory reset? From the thermostat Settings > Reset > All settings? Do you see any message on the thermostat display?

I cannot get to this menu as the "reconnect to heat link" message pops up before.

I understand. The thermostat must be linked with the Heat Link to access the reset menu, unfortunately there is no other option to reset it. To clarify, you don't have the Heat Link at all, have you had any issues with it?

I do have the Heat Link but it is no longer connected.

Alright, thanks for letting me know. Please go to thermostat Settings > Technical Info > Power and let me know the power readings from there.

Thank you. I put in here some steps to help you connect back the thermostat with the Heat Link. The steps need to be fulfilled in this order only.

Before following these steps make sure of the following:

- The thermostat is connected to the base and to a power source and it's getting power (You can check in the "Technical info" option, and after that in "Power", the battery needs to be above 3.8 in order to maintain a constant connection with the Heat Link, however, if it's not, let it charge until it is).
- If you have the possibility (the thermostat is on a stand), bring the thermostat and the Heat Link as close as possible only for the pairing process, after that, you can move them anywhere in the 30 meters radius

1. Gather the 6-digit entry key located on the bottom side of Heat Link's case, near the screw that holds the case together.

2. Select the option "Replace Heat Link" on the thermostat (you will have a message saying that the thermostat failed to connect wirelessly to the heat link, you just need to continue and you will receive a screen with 4 options: check again, reset pairing, replace heat link and technical info, the correct option in the third)

3. Put the 6-digit entry key in there but don't confirm it. Just write it there and stop when you see the word "Connect" highlighted.

4. Press the "Nest" button on the Heat link and hold it for 45 seconds until you see a slowly pulsating blue light on the Heat Link. After that, wait about 5 seconds and press and hold it again for another 45 seconds until you see a slowly pulsating blue light on it.

5. Go ahead and press connect on the Thermostat's display and wait about a minute. You shall see the message "Heat link connected wirelessly" and the Heat Link's light shall be solid green. That means the devices are connected and working.

Let me know how it went.

This cannot work as my heat link is disconnected. It has no power source, unless I can use the USB connector?

Understood. In order to be able to perform a series of troubleshooting steps on it. When the Heat Link is connected to power from the mains, do you see any light on it?

Re: Factory Reset without Heatlink

I cannot connect the heat link for now.

In this case, please contact us back when the Heat Link is connected to the mains so we can troubleshoot it.
