Hi, @Charlielcooke!
Thank you for reaching out to the community. I apologize to hear the Heat Link is not connecting to the thermostat, and it’s not giving any light. I know how important a reliable heating system is, especially during winter. I’d be happy to help you!
I appreciate you taking the time to turn off and on the boiler. To gather all the necessary information and provide you with the best assistance, please answer the following questions:
- What type of thermostat do you have?
- When was your thermostat installed?
- When did the inconvenience start?
- Do you have a system or a combi boiler? Is the control On/Off or Opentherm?
- Have you experienced any recent power outages?
- Has there been any recent work done on your heating system?
In the meantime, please ensure the following:
- Check that the loss of connection is not caused by the distance between components. If it's powered by a USB, bring the thermostat display closer to the Heat Link or move the base together as a unit. Also, it may be caused by signal interference. For more information, refer to this article: Troubleshoot wireless interference.
Additionally, if the steps above don’t work, please reset the Heat Link to default settings and restart the network on the display; after that, try to set up both devices again.
Thank you for your cooperation. I look forward to your response.
Best regards,
Ana
