Quick answers to common questions and simple checks for the most frequent THERMOlink connection and control issues.

Frequently Asked Questions

What boilers can THERMOlink work with?

THERMOlink is designed for compatible OpenTherm heating systems. Check your boiler documentation or installer information to confirm OpenTherm support.

Do I need to keep the mobile app open?

No. Once the system is configured and connected, the app does not need to remain open continuously.

Where can I find setup instructions?

The complete setup sequence is available on the User Manual page.

Can I control the boiler while I am away from home?

Yes, when the THERMOlink controller is online and the heating system is available for remote control.

Troubleshooting

THERMOlink appears offline

First check that the controller has power and that your home internet connection is working. Then confirm that the Wi‑Fi network used during setup is available.

The app opens but the boiler does not respond

Check whether the controller reports an OpenTherm connection problem. Also confirm that the boiler itself is powered and operating normally.

I changed my Wi‑Fi router or password

The controller may need to be configured for the new Wi‑Fi network. Follow the Wi‑Fi setup procedure in the User Manual.

I still cannot solve the problem

Use the Support page to contact us and describe what you see in the app and on the controller.
