Hi there,
Thanks for reaching out. Here are some steps to help you with the H71 error:
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.
