Installation
The Lyric T5 WiFi Thermostat should
be mounted in a suitable location.
• Install the thermostat about
5 ft. (1.5m) above the floor in an
area with good air circulation at
average temperature. See Fig. 1.
• Do not install the thermostat
where it can be affected by:
– Drafts or dead spots behind
doors and in corners.
– Hot or cold air from ducts.
– Radiant heat from sun or
appliances.
– Concealed pipes and
chimneys.
– Unheated (uncooled) areas
such as an out side wall
behind the thermostat.

1 Turn OFF power (important!)
To protect yourself and the equipment,
turn OFF the power at the breaker box
or switch that controls your heating/
cooling system.
2 Make sure the power is OFF!
Try turning ON your heating/cooling
system by changing the temperature. If
you can’t get the system to turn ON in
5 minutes, you’ll know the power is OFF.
3 Take the faceplate off your old
thermostat.
On most thermostats, you can take off
the faceplate by grasping and gently
pulling. Some thermostats may have
screws, buttons, or clasps.
Do not remove any wires from your
thermostat.

Thick bl
wires.
Do you have thick black wires with
wire nuts? Is your thermostat 120V
or higher? If you answered yes to
either of these questions, you have
a line voltage system and the Lyric
thermostat will not work.
If you are unsure visit:

Use a screwdriver or a ballpoint
pen to release wires from
terminals.
Tip: To prevent wires from falling
back into the wall, wrap the wires
around your ballpoint pen.
9 Insert the wall anchors
(included).
It is recommended that you use
the screws and wall anchors
included in the box when
mounting your thermostat.
You can use the Honeywell Standard 16 Connector to mark
where you want to place the wall
anchors. Drill bit size 7/32”.

10 Check for any paint gaps or screw
holes left by the old thermostat.
If you choose to use the optional
Honeywell Decorative Cover Plate
and Standard Installation Adapter to
hide blemishes, snap the Connector
to Installation Adapter. For more
information see page 12.
11 Bundle and insert wires through
the new Honeywell Standard 16
Connector.
Gather the wires and guide them
through the hole in the middle of the
Standard 16 Connector.
Make sure at least 1/4-inch of each
wire is exposed for easy insertion
into the wire terminals. You can use
the “wiring guide” on the Standard
16 Connector door to measure the
correct length for exposed wire.

Set the R-switch up or down based on your
wiring notes in Step 6.
If there is only one wire connected to R,
then your system uses this wire to power
both heating and cooling. Set the R-switch
to the up position.
If you have an R or Rh, and Rc wire, then
your system uses R or Rh to power the
heating system and Rc to power the cooling
system. Set the R-switch to the down
position.

Frequently Asked Questions
Will Lyric thermostat still work if WiFi connection is lost?
Yes, the temperature can be adjusted directly at the thermostat. However, some features, including
shortcuts and geofencing, are managed only through the Lyric app and will not function while the
connection is down. The Lyric thermostat will automatically reconnect to WiFi once the network is
restored.
Lyric thermostat is not finding the in home WiFi network.
Lyric thermostat operates in the 2.4GHz range. That may be why the Lyric thermostat does not
see the network but the smartphone, which operates in both the 2.4 and 5.0 GHz range, sees the
network. Most routers will broadcast two networks, one SSID on the 5.0 GHz radio and one SSID on
the 2.4 GHz radio.
Can Lyric thermostat be used in a home that does not have WiFi?
Lyric thermostat can work as a basic thermostat without WiFi. The key features, including location
based temperature control and custom shortcuts, require a WiFi connection.
Why does the screen on the Lyric thermostat go blank?
When someone is not touching the thermostat, the display goes to sleep to conserve energy or to
not disturb you at night. The thermostat can still be controlled through the Lyric app. Touching the
thermostat screen wakes it up. You can adjust default display behavior in menu of the thermostat.
A change was made on the Lyric app but it has not shown up on the Lyric thermostat.
There may be a short delay after making temperature and setting changes in the app.
Can there be multiple users for geofencing?
Yes, there can be multiple users. Geofencing will trigger based on the last person to leave and the
first person to return. To properly use geofencing with multiple users:
• Each user needs to create their own Lyric account.
• Each user should use their login ID and password across his or her devices, including
smartphones and tablets.
• No two users should share the same account.
Frequently Asked Questions
How are multiple users set up with Lyric thermostat?
Access can be given to any or all Lyric thermostat locations through the Lyric app. Start by pressing
the three-line menu icon in the upper left-hand corner of the home screen. Press the gear wheel
next to the location name. Select Users and press + Add User located at the bottom of the screen.
Type in the email address of the person to be invited. If they have a Lyric account set up, the location
will be automatically added to their account. If they don’t have an account, they will receive an email
invitation prompting them to download the app and create their own account.
Note: All individuals with access to a thermostat share the same user privileges. Users added will be
able to change the thermostat’s settings and shortcuts, as well as add or delete other users.
Is there a way to extend the signal strength?
The range or distance of the WiFi signal is determined by the homeowner’s router. Check the
router’s manual for additional information.
There is a alert that says WiFi Signal Lost. What does that mean?
The WiFi signal to the Lyric thermostat has been lost. Wait for the thermostat to reconnect or select
a new network within the Lyric app configuration menu. If the thermostat is unable to reconnect, you
will need to troubleshoot the router to determine the cause.
Why is the thermostat showing up as offline (strike-through WiFi icon) on top of right corner of
thermostat display?
If the Lyric thermostat displays a strike-through WiFi icon on its screen or shows up as offline
on the Lyric app, it has lost connection to the network. Make sure the router is powered and
broadcasting. The home’s WiFi network may need to be reset by power cycling the router. Consult
the router’s instruction manual for directions on power cycling. When the network has been restored,
the thermostat will automatically reconnect.
An activation email hasn’t been received.
An email will be sent from connectedHome@alarmnet.com. An activation email is needed to
complete the Lyric account setup. If an activation email is not received after five minutes, check the
Spam folder of the email account.
If you do not find it in the Spam folder, click on the Resend button and the activation email will be
resent. If you still do not receive your activation email, please contact the Lyric Technical Support
team at 18006333991 for help.
