It is possible that the thermostat (temporarily) loses the internet connection. If it is not immediately possible to re-establish the connection, this does not necessarily mean that you have to sit in the cold in the winter.
The thermostat connects to the Internet only so you can use the corresponding app. You can still use the thermostat when the internet connection is gone. The thermostat can no longer be controlled via the app, but you can still manually operate it locally.
Many manufacturers give a brief explanation of how you can restore the internet connection. You often have to perform a reset. Once you have completed the steps to reconnect, you can use the app again to control the thermostat.
If after completing the steps it is still not possible to re-establish the connection, there may be another problem. Feel free to contact us, so we can see with you what the cause of the problem is and how you can solve it. Do not forget to provide the information stated in our questionnaire.
