Welcome
Congratulations on your purchase of a Honeywell
Wi-Fi color touchscreen programmable thermostat.
When registered to Honeywell’s Total Connect
Comfort Solutions, you can remotely monitor and
control the heating and cooling system in your home
or business—you can stay connected to your comfort
system wherever you go.
Honeywell’s Total Connect Comfort is the perfect
solution if you travel frequently, own a vacation home,
a business, or manage an investment property or if
you are simply looking for peace of mind.
This thermostat works with common 24 volt systems such as forced air, hydronic,
heat pump, oil, gas, and electric. It will not work with millivolt systems, such as a
gas fireplace, or with 120/240 volt systems such as baseboard electric heat.
MERCURY NOTICE: Do not place your old thermostat in the trash if it contains
mercury in a sealed tube. Contact the Thermostat Recycling Corporation at
www.thermostat-recycle.org or 1-800-238-8192 for information on how and
where to properly and safely dispose of your old thermostat.
NOTICE: To avoid possible compressor damage, do not run air conditioner if the
outside temperature drops below 50°F (10°C).
Need help?
Visit wifithermostat.com or call 1-855-733-5465 for assistance before returning the

wire connections for later
reference.
2b If no wire is connected to
a terminal labeled C or no
C terminal exists on the
old thermostat, view the
Alternate Wiring videos at
wifithermostat.com/videos
or reference the C-wire
addendum in the box.
Important! C wire is required
and is the power source for your
thermostat. Without a C wire, your
thermostat will not power up.

3 Label the wires.
Use the supplied sticky tags
to label each wire as you
disconnect it. Label wires
according to the old thermostat
terminal designations, not by
wire color.
Note: If no tag matches a
terminal designation, write the
appropriate letter on a blank
sticky tag.
4 Remove wallplate.
Remove the old wallplate from
the wall after all wires have been
labeled and disconnected.

Mount your new wallplate
using screws and anchors
included with the thermostat.
If necessary:
Drill 3/16-in holes for drywall.
Drill 7/32-in holes for plaster.
Note: You may be able to use
your existing wall anchors. Hold
the wallplate up to the existing
anchors to check for alignment.

Important! This thermostat requires a C, or common, wire for power. The C, or common,
wire brings 24 VAC power to the thermostat. If you are replacing an existing thermostat,
it might not have a C wire connected to it. Many older mechanical or battery operated
thermostats do not require a C wire. See the C Wire Addendum document included in
this package for more information. If you don’t have a C wire, try:
Note: Not all heating/cooling systems label the 24 VAC common C. Check your system
manual or contact the manufacturer to find out which terminal is the 24 VAC common.

If you have both an Rand Rc wire, unplug the jumper loop by pulling on the wire
loop.
If your old thermostat had both Rand RH wires, connect the Rwire to the Rc
terminal, the RH wire to the Rterminal, and unplug the jumper loop.
If your old thermostat had both Vand VR wires, check wifithermostat.com for help.
If your old thermostat had separate Oand Bwires, and is controlling a single zone
heat pump system, attach the Bwire to the C. If there is more than one thermostat
controlling the system, call Honeywell zoning at 800-828-8367 for wiring assistance.
If your old thermostat had separate Y1, W1, and W2 wires, check
wifithermostat.com for help.
If the old thermostat has separate wires on Aux and E, use a wire nut to attach both
wires to a separate wire. Slide this third wire into the W2-Aux/E terminal.
This is the system monitor. If the monitor finds a problem, you will see an orange alert
button on the thermostat home screen.
