How do I start the initial setup and connect my Lyric T6 Pro Wi-Fi thermostat?

To begin setup, press and hold the center temperature (indoor temperature) on your thermostat for 5 seconds until the screen changes. Then download the Honeywell Lyric app from the App Store or Google Play, open it, and your thermostat should appear under 'Thermostat Found' — tap SET UP NOW to continue. If your thermostat doesn't appear, tap INSTALL A DEVICE and follow the prompts. (Page 2)
