Heatlink error h72

[Speter28]

Come home from work to see error code h72. On the thermostat. The boiler is still working . But there are no lights on the the heatlink. I've reset the boiler and the thermostat and also reset the power supply, yet there is still no lights . It was working this morning but now it seams dead. Please advise.

Hi there @Speter28! I'm really sorry to hear that you encountered this issue, but I'll do my best to help you sort this out. Could you please respond to the following set of questions?

Have you recently had service or maintenance on your electrical, plumbing, or heating system?
How many zones are present in your setup?
Were there any power outages in your area lately?
Have you checked for all the breaker switches to be on?

Have you also tried pressing on the button of the Heat Link? If so, still no lights coming on?
