3rd Gen thermostat wont connect to heat link

Nick07 — Wed, 22 Mar 2023 23:50:30 GMT

Hi, I've just been sent a new 3rd Gen thermostat as the last was faulty. I have set it up on the app and its connected to the WiFi so at least I can use it manually. However, it will not connect to the heatlink. I have tried resetting and now just have a constant blue flashing light. Has been like that for the last 2 hrs. Any advice would be greatly appreciated. PS I'm a 55yr old blonde so I'm impressed I got this far!!! Many thanks

Hello there @Nick07 !

Thanks for posting. I'm so sorry to hear that your facing issues with your thermostat. Could you please try these troubleshooting steps:

Turn off the WiFi router.
1. Reset the Heat Link by keeping the button on it pressed for 30 seconds until the LED goes slowly pulsing blue.
2. Take the thermostat off the base and give it a restart, off the base by holding the display and the back of the thermostat pressed for 10-12 seconds.
3. While the thermostat is restarting, do not put it back on the base yet, but instead, reset the Heat Link again just like before.
4. After the Heat Link is reset, put the thermostat back on the base when it asks you to do so on the screen.
5. Go to: Replace Heat Link and enter the 6 character entry key from the Heat Link, but do not connect just yet.
6. Restart the Heat Link twice (1 restart is a 30 seconds press, until the LED goes off once).
7. Press connect on the display.

Let me know how it goes! Thanks, Oana
