If you have successfully connected your Heat Pump Optimizer X to your home Wi-Fi, but the tado° app shows a configuration error, this means your Heat Pump Optimizer X has taken longer than usual to set up the Thread network.
You can restart configuration by following these steps:
Select Retry.
Make sure your phone is connected to your router’s network (the same Wi-Fi network that the Heat Pump Optimizer X will try to connect to).
Make sure you select Allow when prompted to allow tado° to access your home network. If you selected Don’t Allow, you can return to that screen by selecting Retry.
If you have closed the screen on your tado° app, you can re-enter it by selecting Settings > Rooms & Devices, and selecting Heat Pump Optimizer X from the list of devices. Select the Configure button.
If the issue persists, restart the Heat Pump Optimizer X by accessing the screen display and selecting Menu > Reset device > Restart. Select Retry in the tado° app after the Heat Pump Optimizer X starts up again.
If the issue still persists, do a Factory Reset on your Heat Pump Optimizer X. Close your current app screen, then scan the QR code to reinstall.
Please note: the Heat Pump Optimizer X will only connect to 2.4 GHz. If you have set your router to create an additional 5 GHz network, ensure that your phone is connected to the same network as the Heat Pump Optimizer X.
