During the installation and configuration process, the Lyric app has navigation buttons you can use to go back to an earlier step and change your preferences.
If you need to make changes after completing this process, tap the gear button to open your settings. If your Lyric system settings are incorrect, you will need to fully reconfigure the thermostat. Go to your Lyric app, tap the menu button, and select the gear next to your thermostat location name. Choose Thermostats, select your thermostat name, then select Reconfigure Thermostat.
You will need to have physical access to your thermostat for this process. If you do not recall your system configuration, be sure to note it down before making changes in the configuration. You will be given the option before reconnecting your thermostat to review your new settings before allowing your thermostat to accept them.
