Hey @TomEnd92,

I'm sorry to hear that your Heat Link no longer works, but I'm here to help you sort everything out. Please answer the following questions so that we can properly isolate the issue:

What type of Nest thermostat do you have?
When was it installed?
Did the issue happen during installation or after installation? Was it installed by a Nest Pro or by a regular installer?
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 error 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?
Have you tried any troubleshooting steps before contacting us?
How many thermostats do you have?

Thank you for your answers @TomEnd92.

If you have not already make sure to double check all breakers and switches to make sure nothing has tripped. Also check the boiler as it can have a separate isolation switch sometimes. Confirm the boiler has power, it should have a LED or display that turns on.

If it all looks good try and power cycle the Heat Link, if you're comfortable in doing so. Turn the power off to the Heat Link for a few minutes and then turn it back on. See if it has any reaction when you press the button on it after.

Hello @AnaM

Thank you for answer.

I checked all things, everything is right and the leds will only turned on when I putt in the USB in the front of the heat link. Boiler is working normal with old thermostat.

So I think it's really the heat link and then the 230v circuit
