Installing your Lyric Round Wi-Fi Thermostat - Second 
Generation with Apple HomeKit
These instructions are designed to help guide you through installing the second 
generation Lyric Round™ Wi-Fi Thermostat for intended use with Apple® HomeKit™. 
Integration with Apple HomeKit requires four steps to ensure compatibility and 
operation.
Before you begin:
Lyric’s implementation of Apple HomeKit requires a “C” wire. If your thermostat does 
not have a “C” wire the Lyric Thermostat will still work but you will be unable to utilize 
Apple HomeKit functionality. To learn more about your system compatibility and what 
a “C” wire is, click here.
Step 1: Remove your existing Lyric Thermostat. If 
this is your first time installing a Lyric thermostat, 
proceed to step 2.
A. In your Lyric app, open the main menu (the 
three line icon the upper left hand corner).
B. Locate and tap on the name of the 
thermostat you’re uninstalling and tap 
“Thermostat Configuration.”
C. Take note your configuration settings. You 
will need these when you configure your 
new Lyric Round.
D. Tap on “Delete” to remove the thermostat.
E. Uninstall thermostat from your wall. Refer 
to the Quick Start Guide, if necessary.
