Hi,
My nest heat link (~1 year old) has suddenly stopped working - the thermostat can’t connect the the heat link (h71 error). There are no lights on the heat link so I can’t do a reset, etc. It looks like it might be a common/known issue. Can anyone help? Thanks!

Hi there. Thanks for reaching out. I'll do my best to get this sorted for you as soon as possible.
Here are some helpful troubleshooting steps:
Press the button on the Heat Link and check if you have any lights on it
Check if the circuit breakers and the switches are set to on
Turn them off and then back on
Press on the button again and check for LEDs
Could you also help me with some answers to these questions?
How long has your thermostat been installed for?
Did the issue happen during the installation?
Is there any error on the Nest thermostat display?
Have you had any power cuts recently?
Have you had any work done on your electrical or heating systems recently?
If yes, was the power properly restored at the fuse board after work was done?
How many zones ( thermostats ) are present in the setup?
