Installation precautions
• Before installing or servicing the
thermostat, turn off power to the system
at the circuit breaker.
• Leave power off until you have finished
installing or servicing.
• Shorting the electric terminals at the
control on the heating or cooling system
may damage the thermostat. Do not test
the system this way.
• You must follow all local codes and
ordinances for wiring the system.
• This thermostat should only be powered by
4 AA alkaline batteries or a listed Class 2
power supply at 24 VAC (C-Wire or wall
transformer).
• An amperage higher than 1 amp to each
thermostat terminal may cause damage to
the thermostat.
• Verify that the system is 24 VAC. If the old
system is labeled as 120 or 240 volts or has
wire nuts, the system is high voltage.
Do not install the thermostat to a high
voltage system. Contact a local HVAC
professional for help.

Location
If replacing an old thermostat, the new
thermostat can be mounted in its place.
If a new location is desired it will be
necessary to move the wiring.
New installation and relocation should
follow the accompanying guidelines to
ensure the most accurate temperature
reading and ease of use.
• Mount thermostat on an inside wall,
approximately 5 ft. (1.5m) above the floor
in a frequently used room.
• Do not install in locations near appliances
or devices that affect the local temperature
such as televisions, lamps, or dryers.
• Avoid areas that are exposed to large
temperature variances, such as:
direct sunlight, near an AC unit,
above or below auxiliary heat and
air vents, and drafts from windows.
• Be aware of what is on the other side
of the wall where the thermostat is
being installed. Do not install on walls
adjacent to unheated rooms, stoves,
or housing hot water pipes.
• Damp areas will not only affect the
humidity reading of the thermostat, but
could lead to corrosion and shorten the life
of the thermostat.
• Install in a location with good air circulation.
Stagnant air will not accurately reflect the
rate of temperature change in the room.
• Avoid areas behind open doors, corners,
and alcoves.
• Wait until construction and painting are
finished before installing.
Preparation
Test the system
Verify that the heating and/or cooling system is
operating properly before you try to install the
new thermostat.
CAUTION: Do not test the system by
shorting electric terminals at the furnace or
air conditioner. This may damage
the thermostat.
Turn the power off
Turn all heating and cooling systems off.
This can be done at the circuit breaker.
CAUTION: Do not remove the existing
thermostat until power has been turned off
at the circuit breaker.
Once power to the heating and cooling systems
is off, perform the following steps:
Remove the thermostat cover
Remove the cover from the existing thermostat.
Do not disconnect the wires yet.
Take a picture of the wires before you detach
them from the existing thermostat for
future reference.

6 7
Prepare the wires
Disconnect all of the wires and remove the
existing thermostat. Remember to secure
the wires so they don’t fall into the wall.
Follow these guidelines for safe and secure
wire connections:
• Ensure the wires are a proper gauge
between 18-24 AWG.
• Make sure wires have exposed straight ends
about ⁄” long.
CAUTION: Verify that the system is 24 VAC.
If the old system is labeled as 120 or 240
volts or has wire nuts, the system is
high voltage. Do not install the thermostat
to a high voltage system. Contact a local
HVAC professional for help.
Install the back plate
Use the bubble level provided on the back plate
as a guide. Mark where the screws will go with
a pencil through the screw holes on the
back plate. Ensure the top of the back plate is
facing up.
If necessary, use the trim plate to cover
up any marks or holes left from the
old thermostat. Attach the trim plate before
securing the back plate to the wall.
Drill holes with a ⁄” drill bit to tap in the
drywall anchors for added support
Installation
Wire your new thermostat
Reconnect the wires to the new thermostat
and indicate the connected wires with a
pencil in the image below. This information
will be needed when configuring
the thermostat.
If you have extra wires, do not install them
in the new thermostat. Please contact
your local HVAC professional for
additional assistance.
• If you have R, connect it to RH.
• If you have RH & RC, remove the black
jumper in the lower left corner of the back
plate terminal board with needle-
nose pliers.
• Z can be used for W3, H, DH, or O/B Zoning.

Install the batteries
The thermostat can be powered by battery
or 24 VAC. If a wall transformer is used to
power the thermostat, connect between
C and RH.
Ensure the batteries are installed following
the specified polarity markings on
the thermostat.
CAUTION: SPECIAL BATTERY WARNING
• Always replace the batteries as soon as
you have low battery levels, indicated by
“LOW” then "BATT" flashing on the display.
If the batteries drain, the thermostat
could leave the HVAC system on or off,
overheating or freezing the home.
• Always replace the batteries at least once a
year. This will protect the thermostat from
damage and corrosion by leaking batteries.
• If the home is unoccupied for a month or
more, such as with vacation homes, you
should replace the batteries as a preventive
measure against battery failure while you
are away.
• Always use new batteries as replacements.

Troubleshooting
Heating or cooling doesn’t turn on when
the set point is above or below the
room temperature
To prevent damaging the compressor,
the thermostat inserts a delay when cycling
the compressor. If you think the system should
be on and it’s not, change the set point to
2 degrees beyond the current set point and wait
5 minutes to see if the system turns on.
If not, contact a local HVAC professional.
Heat pump is “cooling when it should
be heating” or “heating when it
should be cooling”
Because both types of heat pump reversing
valves share a single terminal on your
thermostat back plate, you need to be sure
you have the thermostat configured for
the correct wire. Try switching the O/B
configuration setting through your
online account. Contact a local HVAC
professional for further help with this issue.
Exclude the thermostat from the
Z-Wave network
If for some reason the thermostat must be
excluded from the network, follow the
steps below:
❶Set the thermostat to OFF mode.
❷Press and hold the exclusion button on the
Z-Wave controller. Refer to controller
documentation for more information.
❸Press and hold the DOWN button on
the thermostat to enter exclusion mode.
Release the button when the RADIO
icon lights up.
❹When the RADIO icon flashes red,
the thermostat has now been successfully
excluded from the network.
Batteries drain quickly
If a thermostat is included using a “C” Wire,
that information is saved in the network and
cannot be changed unless excluded and included
again without a “C” Wire connected. The same
applies to thermostats included on
battery power.
If you find your thermostat batteries are
draining unusually fast, make sure the “C” Wire
connection is still intact. If a device is included
using the “C” Wire, the Z-Wave communication
never sleeps, and the thermostat will act as a
repeater, sending messages for other devices
as well. If the “C” Wire is removed, this kind of
activity will drain the battery very quickly.
