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 two
AAA alkaline batteries or a listed Class 2 power
supply at 24 VAC (C-Wire or wall transformer).
• An amperage higher than 1 amp through
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.

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.
Make sure the wires are identified correctly. If you
have an unidentified wire, it may be necessary to
identify the wire where it connects to the heating or
air conditioning equipment.
! CAUTION: Wiring can vary for each manufacturer.
Identify all wiring before removing it from the existing
thermostat. Take a picture of the wires before you
detach them from the existing thermostat for
future reference.
Disconnect all of the wires and remove the
existing thermostat. Remember to secure
the wires so they don’t fall into the wall.

6
Prepare the wires
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.
If additional support is necessary, drill holes with
a ⁄” drill bit and tap in the drywall anchors.
Installation
Wire your new thermostat
Connect the wires to the new thermostat.
If you have extra wires, do not connect them
to the new thermostat. Please contact your local
HVAC professional for additional assistance.
• If you have R, connect it to RH.
• If you have RH and RC, you do not need a
physical jumper to connect the two terminals.
RH and RC are connected by a digital jumper.
• Z1 or Z2 can be used for W3, H, DH, or EX.
NOTE: If you have a 2-wire hydronic heating system,
you may need to add the power resistor to the
system. Connect this resistor at your heating
equipment (not the thermostat) between the
C and W terminals. Additional information
about the power resistor can be found in the
Troubleshooting section.

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: BATTERY WARNING
• Always replace the batteries as soon
as you have low battery levels, indicated
by a caution sign and “LOW BATTERY”
flashing on the display. If the batteries drain,
the thermostat could leave the HVAC system
on or off, overheating or freezing the home.
• If the thermostat buttons flash amber when
pressed and the screen does not illuminate,
the batteries in the thermostat are extremely
low. Install fresh batteries immediately.
• Always replace the batteries when they are
low to 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.

Attach the body and back plate
Verify that any excess wire is tucked back into
the wall to allow room for the thermostat
to sit flush against the back plate.
Return the thermoat to the wall plate by pressing
the thermoat body firmly into the back plate
mounted to the wall. Ensure that the pins on the
body are correctly aligned with the back plate. Failure
to do so could cause damage to the thermoat.
Turn the power on
Restore power to all the heating and cooling
systems. This can be done at the circuit breaker.

10
Setup
The thermostat will automatically
detect connected wires.
Follow the on-screen instructions to
complete the thermostat configuration.
NOTE: If the thermostat screen does not show
all the connected wires, remove the thermostat
from the wall and verify that all wires are
properly connected. If issues persist, there may
be a problem with automatically detecting your
wiring. Please see the Bypassing Wire Detection
information in the Troubleshooting section.
Depending on the system type and
configuration, the thermostat may request
the following information during setup:
Heat type
Tells the thermostat whether it should
turn on the fan during a heating cycle.
• Forced air heating: Electric

Backup heat type
Tells the thermostat what type of auxiliary/
backup heating the heat pump uses.
• Electric: This is the most common
type of backup heating.
• Dual fuel: Some heat pumps use a fossil
furnace (for example, natural gas, oil,
or propane) for backup heating.
• If unsure: The system will automatically detect
which heat type is appropriate for your system.
Z1/Z2 terminal function
These are the “dynamic” terminals. If an auxiliary
wire has been connected, please specify the
function it will perform.
• W3: Third stage of heat or aux
• H: Humidifier
• DH: Dehumidifier
• EX: Ventilation (HRV, VRV, air baffle)

Troubleshooting
Heating or cooling doesn’t turn on when the
setpoint 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
setpoint to 2 degrees beyond the current setpoint
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”
Some heat pumps use the O terminal, while others
use the B terminal. Try switching the O or B wire
to the opposite terminal. Contact a local HVAC
professional for further assistance.
