Honeywell Home Lyric T5 Wi-Fi Mode D'emploi page 31

Q Why doesn't a change I made in the app show up on the thermostat? :
: A There may be a short delay when you make temperature and settings changes in the Lyric
app. Wait a few minutes, and if you still don't see your changes on the thermostat, make sure
the thermostat is still connected to Wi-Fi and restart your Lyric app.
Alerts and maintenance notification questions
Q What should I do when the alert symbol appears on the thermostat home screen? :
: A When you see the alert symbol on the thermostat screen, touch Menu and the ALERTS sub-
menu will appear. Touch Select to view alert information. Or, you can view alert information in
the Lyric app. See page 26 for a list of all alert codes, what they mean and the action you
should take.
Software and security questions
Q How can I be sure my thermostat is running the most up-to-date firmware? :
: A When your thermostat is connected to Wi-Fi, it will automatically receive over-the-air firmware
updates from Honeywell. These firmware updates contain things such as new features as well
as security upgrades. Keep your thermostat connected to Wi-Fi to ensure it receives these
updates.
Q How can I prevent a cybercriminal from making unauthorized changes to my thermostat? :
: A If a cybercriminal gains access to your Wi-Fi router, they can tamper with a wide range of
online activities, including the settings on your connected devices. Make sure you change the
default password on your Wi-Fi router, and when you select a new password, make sure it uses
multiple upper- and lower-case letters and special characters.
Thermostat removal questions
Q How can I safely remove my thermostat? :
: A Thermostat removal should ideally be handled by a trained professional as improper removal
can cause electrical shock and equipment damage. If you wish to remove the thermostat
yourself, be sure to turn off the circuit breaker that controls your heating or cooling equipment
before you disconnect any wires. If you don't know which breaker controls your equipment, you
can shut off the main breaker.
Q How can I uninstall my Lyric T5 Wi-Fi thermostat? :
: A If you want to replace your Lyric T5 Wi-Fi thermostat, or if you're moving out of your home
and leaving the thermostat behind, you'll first want to clear out the personal settings that are
stored on the thermostat. (Even when disconnected from power, the thermostat will keep your
settings and home router information in memory.) We recommend resetting the thermostat's
schedule, Wi-Fi and HomeKit settings (if previously connected). See page 24 for more
information on reset options.
