If a banner appears saying Initialization Failed, it means that your Heat Pump Optimizer X had a problem while setting up with your heat pump.
Here are some steps you can try to resolve the Initialization issue:
Ensure devices are powered. Double check both your heat pump and your Heat Pump Optimizer X are correctly connected to the power supply.
Check the Wi-Fi connection on the screen display. If the Heat Pump Optimizer X shows as disconnected from Wi-Fi, refer to our article My Heat Pump Optimizer X has disconnected from the Wi-Fi. How do I fix it?
Verify communication between your Heat Pump Optimizer X and your heat pump by checking the connection icon on the screen display:
If the icon has an X, there could be a wiring issue. Check the wiring by following the installation instructions in the tado° app via Settings > Rooms & Devices > Select your device > Installation Instructions.
If the icon shows that the heat pump is connected, then wiring is not the issue.
4. Restart your Heat Pump Optimizer X, then wait 20 minutes.
If the banner still appears on your Heat Pump Optimizer X, please contact our customer support via chat. They’ll be happy to assist you further.
