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
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.
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.
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!

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.
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:
yourhome.honeywell.com/support
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
terminal.
The Lyric thermostat does not
need jumpers.
