Lyric Thermostat Setup Guide
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.
1. In your Lyric app, open the main menu (the three line icon the upper left hand
corner).
2. Locate and tap on the name of the thermostat you’re uninstalling and tap
“Thermostat Configuration.”
3. Take note your configuration settings. You will need these when you configure
your new Lyric Round.
4. Tap on “Delete” to remove the thermostat.
5. Uninstall thermostat from your wall. Refer to the Quick Start Guide, if necessary.
Step 2: Update the iOS software on your smartphone or tablet to the latest version. Download the latest
Lyric app.
Step 3: Review iOS settings & iCloud
You must have Keychain access enabled for HomeKit to work.
1. On your iOS smartphone or tablet, go to Settings > iCloud. Ensure you are
actively signed in to iCloud.
2. Ensure that iCloud Drive is on.
If iCloud does not appear or if you are still experiencing issues, turn off your
iCloud Keychain. Then turn back on. It may take several minutes for the
synchronization to complete. To learn more about iCloud syncing issue, click

3. Ensure Keychain is on.
