My Thermostat displayed H72
The heat link has no lights and I have tried a reset, power cycle and nothing works.
There is power getting to the heatlink and to the boiler. From my research I see this is a common issue. Could you please advise on replacing the heatlink ASAP.
Thanks

Hi @Jamesoc,
I'm sorry to hear you're experiencing this issue, but we'll sort this out together. Let's start with a few questions:
What type of Nest thermostat do you have?
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?
