Best themostat H71

Hi. We’ve had Nest up and running faultlessly for over 3 years yet this morning the thermostat disconnected from the heat link so no heat. Followed prompts on thermostat to reconnect. Struggled but eventually reconnected but it’s dropped connection again. Nothing has changed so unsure what’s going wrong. Help please? Thanks.

Hi we have recently had this issue on two occasions. The first time I thought I had managed to fix it , as it worked again but, the second time it happened (this morning) I tried doing the same steps to fix it and it won’t reconnect. We have had our Nest only 2 years. So frustrating!!

Hi there,

Thanks for reaching out. The thermostat might disconnect from the Heat Link because of interference. How far is your Heat Link from the boiler? To reconnect them, press and hold the Nest button on the Heat Link until it blinks blue and then press Check again on the thermostat display. If they're still not connected, you can try this:

1. Bring the display and base closer to the Heat Link and make sure the boiler is not in between the Heat Link and thermostat - only if possible.
2. Turn off the router and other WiFi or Bluetooth devices ( router, speakers, cordless phones, baby monitor, etc. ).
3. Select Replace Heat Link.
4. Enter the entry key ( do not confirm it yet ) — you can find it at the bottom side of the Heat Link, near the screw.
5. Restart the Heat Link twice by pressing on the Nest button for 30 seconds each time.
6. Confirm entry key.
