You could have a pairing issue here. Do you have lights on the Heat Link, if yes what colour?

Hi when I press the button for 10 seconds the yellow light goes off temporarily and it appears again as a yellow light. a quick press brings on 2 green lights and turns on the heating but have no control; over it. if I press it for about 20 seconds I get a blue blinking light which indicates it is ready to pair but it just won't connect and comes back with a h71 error

Hey @TessV,

Thanks for the details. Let's try these steps:

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.

Let me know how it goes.
