Get the most from Lyric T5 Wi-Fi Thermostat

Multiple programming options that fit your lifestyle:

  1. Location-Based scheduling – The Lyric thermostat uses your smart- phone’s location to know when you’re away, and saves you energy. Through geofence technology, it senses your return and helps make you comfortable upon arrival. You can always manually change your preset Home and Away temperature either on the thermostat or on the app.
  2. Smart scheduling – Use a combination of geofencing and time scheduling to fit your busy, active lifestyle.
  3. Time-Based scheduling – Program your thermostat for one week; each day (each day is a different schedule); Mon-Fri, Sat, Sun; or Mon-Fri, Sat-Sun. All days with four adjustable periods per day.
  4. No scheduling – Control your comfort manually by adjusting temperature set points only.
  • Smart Alerts. Push notifications remind you of filter changes and warn you of extreme indoor temperatures.
  • Smart Response. Learns your heating and cooling system to deliver the opti- mal temperature at the right time.
  • Auto Change From Heat to Cool. Automatically determine if your home needs heating or cooling to provide maximum comfort.

Removing Your Old Thermostat

  1. Turn power OFF
    To protect yourself and your equipment, Turn off the power at the breaker box or switch that controls your heating/cooling system.
    Image 04
  2. Check that your system is off
    Change the temperature on your old thermostat. If you don’t hear the system turn on within 5 minutes, the power is off.
    Note: If you have a digital thermostat that has a blank display, skip this step.
    Image 05
  3. Remove your old thermostat from the wall plate
    On most thermostats, you can take off the thermostat by grasping and gently pulling. Some thermostats may have screws, buttons, or clasps.
    Do not remove any wires from your thermostat at this time!
    Image 06
  4. Make sure there are no 120/240V 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:
    Image 07
  5. Take a picture of how your wiring looks right now
    Be sure to include the letters next to the terminals where the wires are inserted. This will be a helpful reference when wiring your Lyric thermostat.
    Tip: If the color of your wires has faded or if 2 terminals have the same wire color, use the wire labels provided in the package to label each wire.
    Image 08
  6. Remove any Jumpers
    A jumper connects one terminal to another terminal. It may look like a small staple or even a colored wire and must be removed before continuing. Use a screwdriver to release wires from terminals.
    The Lyric thermostat does not need jumpers.
    Image 09
  7. Record if you have wires in the following terminals
    Do not include jumpers as a part of your count. The Lyric thermostat does not need jumpers.
    Image 10
  8. Write down the color of the wires

    Check all that apply (Not all will apply):
    S and U terminals are not supported with this thermostat.
    If there are wires in terminals that are not listed, you will need additional wiring support. Visit to find out if the Lyric thermostat will work for you.
  9. Disconnect the wires and remove the old wall plate
    Use a screwdriver to release wires from terminals.
    Tip: To prevent wires from falling back into the wall, wrap the wires around a pencil.

Frequently Asked Questions

  • Will the Lyric T5 Wi-Fi thermostat still work if Wi-Fi connection is lost?
    Yes, the temperature can be adjusted directly at the thermostat. However, some features, including geofencing, are managed only through the Lyric app and will not function while the connection is down. The Lyric thermostat will automatically reconnect to Wi-Fi once the network is restored.
  • The Lyric T5 Wi-Fi thermostat is not finding the in home Wi-Fi 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.
  • A change was made on the Honeywell Lyric App but it has not shown up on the Lyric T5 Wi-Fi 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.
  • How are multiple users set up with Lyric thermostat?
    Access can be given to any or all Lyric thermostat locations through the Honeywell Lyric App. Start by touching the three-line menu icon in the upper left-hand corner of the home screen. Select Manage Users and touch 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, as well as add or delete other users.
  • Is there a way to extend the signal strength?
    The range or distance of the Wi-Fi signal is determined by the router. Check the router’s manual for additional information.
  • There is an alert that says Wi-Fi Signal Lost. What does that mean?
    The Wi-Fi signal to the Lyric thermostat has been lost. Wait for the thermostat to reconnect or select a new network within the Honeywell 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 Wi-Fi icon) on top of right corner of thermostat display?
    If the Lyric thermostat displays a strike-through Wi-Fi icon on its screen or shows up as offline on the Honeywell Lyric App, it has lost connection to the network. Make sure the router is powered and broadcasting. The home’s Wi-Fi 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 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 1-800-633-3991 for help.
