Thank you for reaching out to us here @Snostock . I'd be happy to try and assist you.
If you have not already, check the breakers and switches at the location, to make sure nothing has tripped. Also check the boiler as it can sometimes have a separate switch on it. Confirm it has power, it should have a display or LED 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 to the Heat Link off for a few minutes and then turn it back on. See if it has any reaction after when you press the button on it.
If it still has no reaction after it would be best to reach out to our support lines so they can create a case for you and assist you further. Here is the link in case you need it: https://bit.ly/3apBRyV .
