Hello everyone,
im having issue with connection between thermostat and heat link. It displays h1 error message.
Since last 2 years there was no issues. I’m trying to reset and paired again but no improvements.
I have been performing troubleshooting but no luck. Also I’ve been reading similar issues on this forum but nothing help. Is there any assistance in Ireland so I could call for technician? Or should I replace the unit?
Any advice?
Thank you

Hi VadiKus,
Thanks for reaching out. i'm sorry for the delay. An H1 message or code says 'Nest can’t connect to Heat Link and won’t be able to control your heating'. In addition, the Heat Link's status light will be yellow when it’s disconnected from your Nest Thermostat.
Follow the guides below:
Restart the Heat Link
Move your thermostat and test the connection
Your thermostat may be too far away from the Heat Link or there may be something interfering with the wireless Thread connection.
Check your Heat Link installation
The wireless thermostat connection can be blocked if your Heat Link is installed too close to your boiler or hot water tank. Make sure that the Heat Link is installed at least 1 m (3.3 ft) away from your boiler or heating system. Reposition it if possible.
Caution: It’s important to protect you, your system and your thermostat. Turn off the power to your system at the fuse box before exposing or adjusting any wiring.
Reset the Heat Link to defaults
Try resetting the Heat Link and then reconnecting it to your thermostat. For complete instructions, please see How to restart the Heat Link or reset it to factory defaults.
In some cases, you may need to re-enter the Heat Link’s pairing code on your Nest Learning Thermostat. The code is a combination of six letters and numbers.
Stop wireless interference from other electronics
Best,
Jenelyn
