Get the most from T5 Smart Thermostat
Multiple programming options that fit your lifestyle:
1. LocationBased scheduling – The thermostat uses your smartphone’s
location to know when you’re away, and saves you energy. Through
geofence technology, it senses your return and helps make you comfort-
able upon arrival. You can always manually change your preset Home and
Away temperature either on the thermostat or on the Honeywell Home 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 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
120V/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 thermostat will not
work.
If you are unsure visit:
resideo.com
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 thermostat does not
need jumpers.

9 Do you see a wire connected to the C terminal?
If yes, skip to step 10.
If you do not see a C wire, proceed with the options below:
Option A - Finding the CWire:
There might be an extra wire pushed into the wall or
wrapped around the wire bundle. Gently pull the wire
bundle out of the wall to check for unused wires.
If you have an unused wire, connect that wire to the C
terminal on your new thermostat in step 13.
Connect the other end of the unused wire to the C
terminal on your heating/cooling system (or the zone
panel if your home uses more than one thermostat to
control temperature). Be sure any other wire(s) con-
nected to the C terminal stay securely connected when
you re-tighten the terminal.
Not all heating/cooling equipment use the C label for the 24 VAC common wire.
If your heating/cooling equipment does not have a C terminal, check the system
manual or contact the manufacturer to find out which terminal is the 24 VAC
common.
Complete installation by following the remaining steps in this guide.
Option B - Using the CWire Power Adapter:
If you do not have an unused wire in the wall, see the C Wire Adapter Installation
Guide included in the box. Open the top or bottom flap of the box to locate the
C Wire Adapter.
10 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.
