3. REMOVING OLD THERMOSTAT
3.1 Turn off power
To prevent electrical shock and/or equipment damage, disconnect electrical power to the system at the main fuse or circuit breaker box, or by flipping
a switch at the air handler. Do not restore power until installation is complete.
WARNING
!
To ensure the power to your heating and cooling system has been turned off, try to turn on heating or cooling by
changing the temperature on your old thermostat.
or

6
3.2 Remove the old thermostat cover
Remove the old thermostat’s front cover from the wall base. Some covers pull of easily, while others may need to be
released by using a screwdriver.
3.3 Label wires
Tip: Taking a picture with a camera or smartphone can help you not only remember how wires are connected
to the terminals, but can also ensure that you label your wires correctly. Mislabeling the wires may result in a
high energy bill or damage to your heating and cooling system.
Your old thermostat may have a sealed glass tube containing mercury. Be careful not to damage the tube or dispose of the tube in your trash. For safe
disposal information, please see Mercury Notice on page 36.
CAUTION
!
Using your screwdriver, carefully unscrew one wire at a time from the terminal block and attach the corresponding
wire label sticker.
Please note that not all terminals may be used, and that there’s no standard color code for thermostat wires, so your
wire colors may vary. For your reference, we’ve included a terminal label reference chart below to help you connect
the wires in your old thermostat to your new thermostat in case you get stuck.

7
Terminal labeling reference chart
If your current terminal has
the following letter
Label the wires with the
following letters Terminal function
RH, R, R5, 5 RH 24V Power (Heating)
RC RC 24V Power (Cooling)
W, W1, 4 W Heating Relay
Y, Y1 Y Cooling Relay
G G Fan Relay
O O Reversing Valve (for heat pump applications
energized in Cool mode)
B B Reversing Valve (for heat pump applications
energized in Heat mode)

8
3.4 Identify jumper wire
For terminal RC and RH:
On your old thermostat, if… Then, on your new thermostat…
Terminal RC and RH are connected
with a jumper wire Leave the jumper wire in its place
There’s only one R wire (RC, RH, R or R5)
coming out of the wall Leave the jumper wire in its place
Terminal RC and RH (or 5 or R5) are NOT
connected by a jumper wire Remove the jumper wire between RC and RH
For terminal Y and W:
If you have a heat pump with reversing valve, connect Y and W with a jumper wire on your new thermostat.
If you need help with labeling and wiring, please contact Customer Support at 877.654.9394 or email
wr[email protected] — we’re here to help!

3.5 Remove old thermostat base
With all of your wires disconnected and properly labeled, you may now safely remove the thermostat base from
your wall.
Tip: Worried about having your wires falling into your wall? Keep the wires secure by wrapping the them
around a pencil.

10
4. MOUNTING AND WIRING YOUR NEW THERMOSTAT
4.1 Install new thermostat base
Mount your new thermostat base using the supplied screws. Drill holes and insert wall anchors to secure the
thermostat base to the wall, if necessary.

11
4.2 Connect wires to corresponding terminal blocks
Match each labeled wire to it’s corresponding terminal on the mounted thermostat base. Insert each labeled wire into
the hole of it’s matching terminal, and using the screwdriver, tighten the screw on the terminal block securely.
Take care when securing and routing wires so they do not short to adjacent terminals or rear of thermostat. Personal injury and/or property damage
may occur.
CAUTION
!
If you have either a gas or oil furnace, set the switch to GAS.
If you have an electric furnace, set the switch to ELEC.

4.4 Install the batteries and attach front cover
Install the included AAA alkaline batteries and push the front cover on to the thermostat base until it’s secure.
4.5 Turn on power
Turn on your power at the source.
Congratulations! You’ve completed the thermostat installation process
5. CHECK THERMOSTAT OPERATION
Tip: If at any time during testing your system does not operate properly, please contact Customer Support at
877.654.9394 or email wr[email protected]
If at any time during testing your system does not operate properly, contact a qualied service person.
Note: To prevent static discharge problems, touch side of thermostat to release static build-up before touching
any keys.

13
5.1 Fan operation
If your system does not have a G terminal connection, skip to Heating System.
1. Turn on the power system
2. Move FAN switch to ON position. The blower should begin to operate.
3. Move FAN switch to AUTO position. The blower should stop immediately.

14
5.2 Cooling system
To prevent compressor and/or property damage, if the outdoor temperature is below 50°, DO NOT operate the cooling system
CAUTION
!
This thermostat has a time delay between cooling cycles to allow the head pressure in the compressor to stabilize.
If the temperature is adjusted to call for cool within 5 minutes of the last cycle the snowflake icon will blink indicating
the thermostat is locked out. After 3 to 5 minutes, the compressor will start and the snowflake icon will stop flashing.
This helps prevent the compressor from cycling too quickly and is normal operation for the thermostat.
1. Move SYSTEM switch to COOL position.
2. Press  to adjust thermostat setting below room temperature. The blower should come on immediately on
high speed, followed by cold air circulation
3. Press  to adjust temperature setting above room temperature. The cooling system should stop operating.

15
5.3 Heating system
1 Move SYSTEM switch to HEAT position. If the heating system has a standing pilot, be sure to light it.
2. Press  to adjust thermostat setting above room temperature. The heating system should begin to operate.
3. Press to adjust temperature setting below room temperature. The heating system should stop operating.

16
6. PROGRAMMING YOUR THERMOSTAT
Before you begin programming your thermostat, you should be familiar with its features and with the display and the
location and operation of the thermostat buttons. Your thermostat consists of two parts: the thermostat cover and the
base. To remove the cover, pull it straight out from the base. To replace the cover, line up the cover with the base
and press until the cover snaps onto the base.

6.3 Operating features
Now that you are familiar with the thermostat buttons and display, read the following information to learn about the
many features of the thermostat.
• SIMULTANEOUS HEATING/COOLING PROGRAM STORAGE — When programming, you can enter both your
heating and cooling programs at the same time. There is no need to reprogram the thermostat at the beginning
of each season.
• TEMPERATURE OVERRIDE— Press or until the display shows the temperature you want. The
thermostat will override current programming and keep the room temperature at the selected temperature until
the next program period begins. Then the thermostat will automatically revert to the program.
• HOLD TEMPERATURE — The thermostat can hold any temperature within its range for an indenite period,
without reverting to the programmed temperature. Press HOLD button. “HOLD” will be displayed. Then choose
the desired temperature by pressing or  The thermostat will hold the room temperature at the selected
setting until you press the RUN button to start program operation again.
• ENERGY MANAGEMENT RECOVERY — Energy Management Recovery (EMR) causes the thermostat to start
heating or cooling early to make the building temperature reach the program setpoint at the time you specify.
Heating will start 5 minutes early for every 1° of temperature required to reach setpoint. Cooling will start ap-
proximately 15 minutes early for every 1° because it takes longer to reach temperature. Clipping W903 jumper
will disable EMR.
