I have a 3rd gen. learning thermostat (UK version) and its been installed 2yers

and its heatlink went dead 2days ago.

it didn't turn on, no lights at all.

becasue of the "heatlink is offline, h72" message was displayed on the display that I can realized the problem.

heres South Korea. and I think google nest doesn't provide customer service at here

Is there any way that I can get help with this problem?

Thanks for letting us know, @pinkjaguar. We're sorry you're having issues with the Heat Link. No worries. Help's here.

Please answer the following questions:

Are there any lights on the Heat Link?
Does the boiler activate when calling for heat by pressing the Heat Link's button to activate Manual Mode?
Are you seeing any wiring report or message on the thermostat and/or the app?
Have you had any recent power cuts in your area? If yes, has the power been restored?
Have you recently had service or maintenance on your electrical, plumbing, or heating system?
If yes, how long was the power off for? (Be specific.)
Could you tell us please if you've checked on the breaker switch and fuse box?
Any blown fuse in there? Have you tried to turn the breaker switch off and on again? Any difference?
