Frequently asked questions (FAQs)
Wi-Fi connection questions
Q Will the thermostat still work if the Wi-Fi connection is lost?
: A Yes, you can still manually adjust the temperature at the thermostat. However, some features
such as location-based temperature control (geofence technology) can only be managed
through the Lyric app and will not function without a Wi-Fi connection. The thermostat will
automatically reconnect to Wi-Fi once the network is restored.
Q Why is the thermostat not finding my Wi-Fi network?
: A The Lyric T5 Wi-Fi thermostat operates in the 2.4GHz range. Smartphones operate in both
the 2.4 and 5.0 GHz ranges, so your smartphone may "see" your Wi-Fi network when your
thermostat does not. Most Wi-Fi routers will broadcast two networks: 2.4 GHz and 5.0 GHz. If
you have an option, make sure your smartphone is connected to the 2.4 GHz network.
Q Is there a way to extend the strength of my Wi-Fi signal?
: A The range (distance) of your Wi-Fi signal is determined by your router. Try moving your router
closer to the location of the thermostat, or use a router with a stronger signal range.
Q There's an alert that says "Wi-Fi Signal Lost" – what should I do?
: A Wait 5 minutes for the thermostat to reconnect or select an alternate network (if you have
one) in the Lyric app configuration menu. If the thermostat isn't able to reconnect, you'll need
to troubleshoot the router to determine the cause.
Q Why is there an offline symbol (Wi-Fi icon with a strikethrough) in the upper-right corner
of the thermostat screen?
: A The thermostat has lost its connection to the Wi-Fi network. First, make sure your Wi-Fi router
is plugged in and broadcasting a signal. If it is, try resetting the router (consult the router's
manual for instructions). When the Wi-Fi network has been restored, the thermostat will
Lyric account and app questions
Q Why haven't I received an account activation email?
: A If you haven't received an activation email after 5 minutes, check your Spam folder and look
for an email from Connected-Home@alarmnet.com. If you don't see it, tap Resend to have the
activation email resent. If you still don't receive it, please contact the Lyric Technical Support
team at 1-800-633-3991.
Q Can I set up my thermostat with multiple users?
: A Yes. To add users, log into the Lyric app and tap the menu icon in the upper-left corner. Select
Manage Users, tap Add User and type in the email addresses of the people you'd like to invite. If
they already have a Lyric account set up, the thermostat and its location will automatically be
added to their account. If they don't have an account, they'll receive an email prompting them
to download the Lyric app and create a new account.
Q Can I set up location-based temperature control with multiple users?
: A Yes. Location-based temperature control (geofence technology) will activate based on the
last person who leaves and the first person to return. Each user will need to create their own
Lyric account with a login ID and password. Two users should not share the same account.
Each user will then need to enable location-based temperature control. See page 13 for
