Hi
As many others here have experienced, I have no power in my Heat Link and an error H71 was showing.
I've troubleshooted as advised on other posts
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 impact
Make sure the breakers are on or the fuse board hasn't tripped. All as expected
Moreover, to have a better view over each of your cases, please help us with some answers:
How often do you experience the issue? Once
How long has your thermostat been installed for? About 2 years
What colour is the Heat Link LED? No Lights
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
Any help or advice would be greatly appreciated!
Thanks a million
