Hi everyone,
Thanks for reaching out and sorry for the late reply. We're sorry to hear about your Nest thermostats.
I'd kindly ask all of you to try these steps:
Does anything happen if you press its button for 30 seconds? NO
In some cases the boiler will have an additional isolation switch which can turn off the power to both the Heat Link and the boiler. Can you try switching that off/on again to see if anything changes? NO CHANGE
Make sure the breakers are on or the fuse board hasn't tripped.ALL GOOD
Moreover, to have a better view over each of your cases, please help us with some answers:
How often do you experience the issue? FIRST TIME, arrived home and it was off
How long has your thermostat been installed for? One year
What colour is the Heat Link LED? No led
What is showing on the Nest thermostat display? H71
Have you had any power cuts recently? NO
Have you had any work done on your electrical or heating systems recently? NO
How many zones are present in the setup? ONE
Is there power present to your boiler? YES
Once you've tried these steps and if you still have this issue with your Heat Link, please reply to the thread confirming that the steps were carried out, together with the answers for the above questions and we'll make sure to further assist you with this.
