Welcome
Congratulations on your purchase of a Resideo
Smart Colour touchscreen programmable
thermostat. When registered to 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.
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

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: Please do not dispose of your old thermostat with
other household refuge as it may contain mercury. Please help to protect the
environment by recycling your old thermostat and batteries in accordance
with local regulations.
NOTICE: To avoid possible compressor damage, do not run air conditioner if
the outside temperature drops below 50°F (10°C).
Need help?

reference.
2b If no wire is connected to
a terminal labelled C or no
C terminal exists on the old
thermostat, view the
Alternate Wiring videos at
getconnected.honeywellhome.com
Important! C wire is required
and is the power source for your
thermostat. Without a C wire, your
thermostat will not power up.
Note: You will need a
picture of your wire
connections to wire the
new thermostat.

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 colour.
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
labelled and disconnected.

5 Mount wallplate for smart
thermostat.
Mount your new wallplate
using screws and
anchors included with the
thermostat.
If necessary:
Drill 4.5mm holes for
drywall.
Drill 5.5mm 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! The Smart thermostat requires a C wire to operate. The C, or common,
wire brings 24 VAC power to the thermostat. Many older mechanical or battery
operated thermostats do not require a C wire. If you don’t have a C wire, try:
• Looking for an unused wire that is pushed into the wall. Connect that wire to C
and check that it is connected to the 24 VAC common at your heating/cooling
system. Check the video section at honeywellhome.com/wifi-thermostat
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.

Leave jumper loop in place.
If your old thermostat had both Vand VR wires, check honeywellhome.com/
wifi-thermostat for help.
If your old thermostat had separate Oand Bwires, attach the Bwire to the C
terminal. If another wire is attached to the Cterminal, check honeywellhome.
com/wifi-thermostat for help. Attach the Owire to the O/B terminal. On the
Type of Changeover Valve screen, select Cooling Changeover Valve. See page
28. If your old thermostat had an Owire and not a Bwire, attach the Owire
to the O/B terminal.
If your old thermostat had separate Y1, W1, and W2 wires, check
honeywellhome.com/wifi-thermostat 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.
