Welcome
Getting set up and ready is simple. Read before installing.
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.
1.1 Switch OFF power to your
heating/cooling system
1.1a Important! To protect your
equipment, switch OFF the
power to your heating/
cooling system at the
breaker box or the system
switch.
1.1b Confirm power is OFF.
Try to turn on heating/
cooling equipment by
changing temperature
on your old thermostat.
Your power is OFF if your
system does not turn ON.

If you have an older thermostat with a
sealed mercury tube, see warning page
for proper disposal instructions.
1.2 Remove old thermostat
faceplate and leave wires
connected
1.2a Take a picture of the wire
connections for later
reference.
1.2b 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
Important! C wire is required
and is the power source for your
thermostat. Without a C
wire, your thermostat will
not power up.
1.3 Label wires
Do not label by wire color.
Use the supplied sticky tags to label
each wire as you disconnect it. Label
wires according to 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.
Note: Wrap the wires around a pencil
to prevent them from falling back into
the wall.
1.4 Remove wallplate
Remove the old wallplate from
the wall after all wires are
labeled and disconnected.

Mount your new wallplate using
screws and anchors included
with the thermostat.
If necessary:

• 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.

1.6a Starting with the C Wire, match
the sticky tag on the wire to the
terminal labels.
1.6b Straighten wire and gently slide
into terminal hole until it clicks
into place. (If you need to
remove a wire, use a pen tip to
press the terminal release and
then pull the wire out.)
Note: Refer to the wiring picture
you took in Step 1.2.
Tip: To make it easier to slide the
wire into place, use a pen tip to
hold down the terminal release.
Note: The wiring for your
application might be different
than the wiring shown below.
