How do I connect my Lyric T6 Pro Wi-Fi thermostat to my home Wi-Fi network?

To connect to Wi-Fi, ensure your smartphone is connected to a 2.4 GHz Wi-Fi signal, then press and hold the indoor temperature in the center of the thermostat screen for 5 seconds until the screen changes. Download the Lyric app from the App Store or Google Play, then open the app — your thermostat should appear under 'Thermostat Found.' Tap 'SET UP NOW' to continue, or tap 'INSTALL A DEVICE' and follow the prompts if it doesn't appear automatically. Note that the thermostat only supports 2.4 GHz Wi-Fi and will not connect to a 5.0 GHz network. (Page 10)
