Heat link stopped working

[Matt3534]

Hi

My nest heat link has stopped working, completely so thermostat cannot connect to it.

No lights at all, I have tried reset procedures but it remains unlit/dead. Power is still provided to heat link but heat link is not turning on.

Error code showing on thermostat: H71

installed: September 2020

From reading the support community this is definitely not an uncommon problem.

Hi there,

Thanks for reaching out. I'll do my best to get this sorted for you as soon as possible.

Here are some helpful troubleshooting steps:

Press the button on the Heat Link and check if you have any lights on it
Check if the circuit breakers and the switches are set to on
Turn them off and then back on
Press on the button again and check for LEDs

Could you also help me with some answers to these questions?

How long has your thermostat been installed for?
Did the issue happen during the installation?
Is there any error on the Nest thermostat display?
Have you had any power cuts recently?
Have you had any work done on your electrical or heating systems recently?
If yes, was the power properly restored at the fuse board after work was done?
How many zones ( thermostats ) are present in the setup?


Regards,
Cristian
