No lights on heat link

Michael4 — Thu, 03 Feb 2022 09:44:05 GMT

I have no heat! The thermostat is working but there are no lights on the heat link. We had a power cut on Monday and Tuesday but I think it came on after that but no heat on Wednesday. There is power to the unit but no lights. I have held the button on the front of the unit for 20seconds as advised but no success. Installed in Jan 2020

Hi there, @Michael4

We're sorry to hear that and we're sorry for any inconvenience our product has caused. Could you tell me please when did the situation start occurring first and when was the thermostat installed?

Also, please answer to the following questions:

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?
If yes, how long was the power off for? (Be specific.)
Could you tell us please if you've checked on the breaker switch and fuse box?
Any blown fuse in there? Have you tried to turn the breaker switch off and on again? Any difference?

Since I haven't heard from you in a while, I'll have to close this thread. Should anything else come up, please open another thread and we'll take it from there. Have a good one and stay safe!
