The programming is stored in the internal memory of the Gateway, so it continues to follow the programming set by the user with the app. Until the connection is restored, you will not be able to make any changes to the system via the app, but you will be able to manually change the required temperature via the Comfort Control electronic controls. You can use the Gateway’s hotspot network as a temporary solution to change the programming, but since not all of the app’s features are available, we suggest that you restore the internet connection as soon as possible.
