- Make sure that you've completed every step in the online installation assistant. If not, please check that you’ve wired the Smart Thermostat as mentioned in the online installation assistant.
- If the installation is completed and the error code does not disappear after a while, please restart the Thermostat by pressing and holding the button on it for 10 seconds.
