MOUNTING LOCATION:
On replacement installations, mount the new thermostat in place of the old one
unless the conditions listed below suggest otherwise. On new installations,
please follow these general guidelines:
1. Mount the thermostat on an inside wall, about 5 ft. (1.5m) above the floor.
2. Do not locate the thermostat where air circulation is poor such as in a corner,
alcove, or behind a door that is normally left open.
3. Do not locate the thermostat where unusual heating or cooling conditions may
be present, such as: direct sunlight, above a lamp, television, or radiator, or on
a wall next to an exterior door or window.
4. Do not locate in a damp environment, as this can lead to corrosion that may
shorten thermostat life.
5. If painting or construction work is still ongoing, cover the thermostat
completely or wait until this work is complete before installation.
WARNING:
All wiring must conform to the local codes and ordinances that are in your
particular location.
REMOVE OLD THERMOSTAT:
1. Turn OFF the electricity to all heating and cooling
components. Do not turn the electricity back on until
all work is completed.
2. Remove the front portion of your old thermostat to
expose the wiring connections.

O
3. Write down the letters printed near each wire terminal
that is used, and also the color of each wire that is
connected to it. Self-adhesive wire labels are also
enclosed.
4. Carefully remove the wires one at a time, and bend them in a manner so that
they do not fall back inside the wall. Do not allow bare wire ends to touch
each other.
5. Loosen the mounting screws for the old thermostat and carefully remove it
from the wall.

Off
Cool
HOUSING RELEASE TABS
(UNDERNEATH BOTTOM EDGE)
1. Strip wire insulation leaving only 3/8 in. (9.5mm) bare wire ends, and clean off
any corrosion present.
2. Fill the wall opening with non-combustible insulation to prevent drafts from
affecting the thermostat’s normal operation.
3. Separate new thermostat housing using your thumb and index finger. Provide
pressure in opposite directions to the release tabs under the bottom edge of
the housing.
4. Route the wires through the opening in the new thermostat base plate, and
hold the base against the wall. Try to line up the screw holes from the prior
thermostat, and install the mounting screws.
5. If the previous holes cannot be used, hold the thermostat base against the
wall so that it appears straight and level (position the base for best
appearance) and mark for the new screw holes. Attach the base to the wall
using the screws provided (use the supplied plastic anchors if needed when
mounting to a soft material such as drywall).

WIRING INFORMATION:
CONNECTING THE WIRES:
When attaching the wires to the thermostat, please ensure that the bare wire
ends are held ALL the way into the terminal block while the screw is being
tightened.
WIRING BASE PLATE NOTICE:
This thermostat model is part of a family of similar models that have the same
general visual appearance. Even though this base plate may look the same as
base plates from other models, the wiring connections may have different
terminal letters for different purposes. Please do not interchange the back plates
and/or thermostat front halves of other similar looking models. Doing so may
cause undesired heating and/or cooling operation to occur.

WIRING DIAGRAM NOTES:
(Important, please read all notes before connecting wires)
• If the information provided in the following wiring diagrams does not clearly
represent or match your system, please refer to the “TECHNICAL ASSISTANCE”
section of this manual, and contact us before removing any of your existing
thermostat wiring.
• All of the dashed wires shown in the wiring diagrams are either optional, or
their usage depends upon your specific system type or brand. For example:
Diagram #1 shows the fan wire as optional. If your system does not have a
fan, than this terminal will not be used.
• Terminal letters shown in black represent typical wiring applications.
Depending upon the brand of your specific system or thermostat, your terminal
letters may not match exactly. Terminal letters shown in gray represent other
possible wiring designations that you might see on your existing thermostat
terminals.
• The optional “C” terminal is used for powering the thermostat by the 24-volt
system, using the System Common wire. This can be used alone, or in
addition to installing batteries as a backup. NOTE: connecting the System
Common wire to the thermostat is not necessary for heating and cooling to
function properly.
• If your old thermostat has both a “Y” and “C” wire both present, then “C” is
most likely a System Common wire.
• If your old thermostat has both an “O” and a “B” wire present, then “B” is
likely a System Common wire and may be connected to the “C” terminal.
Connecting a System Common wire to this thermostat’s “B” terminal may
damage the thermostat, and also your heating and cooling system.
• If replacing an old thermostat that has a mechanical clock, there may be two
wires labeled as “C” for the clock power. Tape off these wires and do not
connect them to the “C” terminal of this thermostat.

COMPLETE THE INSTALL:
INSTALL BATTERIES INTO THERMOSTAT: Install two brand new Energizer® or
DURACELL® “AA” size alkaline (only) batteries, into the thermostat’s battery
compartment. Ensure the batteries are installed in the proper direction.
GAS / ELEC CIRCUIT BOARD OPTION (“G” TERMINAL FAN OPERATION): This
setting is a plastic shorting cap called a jumper. This jumper must remain
installed, and set to either GAS or ELECTRIC for your system to work properly.
This setting changes how your system’s blower fan (if applicable) is controlled
while the thermostat is in HEAT mode, when the Fan switch in the AUTO position.
This setting does not affect the fan operation while in COOL mode.
When set to “GAS”, the blower fan is controlled solely by the heating system
itself. Systems that would typically use the “GAS” setting would be: natural gas,
propane, or oil furnaces, and boilers.
When set to “ELEC”, the blower fan is controlled directly by the thermostat. This
setting is required for heating systems that do not control their own fan, such as
HEAT PUMPS, and units that only have an electric-resistive heating element as
the heat source.
NOTE: If your blower
fan does not operate
properly after
installation, move the
Gas / Electric option
to the “Electric”
setting.

B/O CIRCUIT BOARD OPTION (FOR HEAT PUMP APPLICATIONS): This setting is a
plastic shorting cap (called a jumper) which determines the operation of the
shared B/O wire terminal connection. This jumper must remain installed for a
Heat Pump system to be able to provide heating and cooling as needed, and the
majority of heat pumps today use the default “O” setting. The symptoms that will
occur if this setting is not correct will be: heating while in cool mode, and
cooling while in heat mode.
When this is set to “O” (factory default), the shared B/O terminal will be turned
on while in COOL mode, and off in HEAT mode.
When this is set to “B” (which is needed for some Rheem, Ruud, and Bard heat
pumps), the shared B/O terminal will be turned on in HEAT mode, and off in COOL
mode

FRONT PANEL ITEMS:
HEAT / OFF / COOL, SYSTEM MODE SWITCH: Set this switch to HEAT to control
your heating system, and COOL to control your cooling system. The OFF position
will disable both the heating and cooling units.
AUTO / ON, FAN MODE SWITCH: When this switch is in AUTO, the blower fan (if
present in your system) will automatically cycle on and off by itself while heating
or cooling is running. When in the ON position, the blower fan will run constantly
with or without a demand for heating or cooling, even when the System Mode
switch is in the OFF position.
NOTE: The Fan Mode switch only works if your system provides a wire for the
thermostat’s “G” wire terminal, to control a blower fan. The Fan Mode switch
has no effect in systems that do not have a blower fan (such as a hot water
radiator system).
SET BUTTON: This button is used to access the setup options menu, and other
additional features.
UP / DOWN BUTTONS: The UP and DOWN buttons are used to control the set
temperature, or adjust any other on-screen items. Typically, an item that is
flashing can currently be adjusted.
17
SYSTEM CONFIGURATION AND SETUP OPTIONS:
Setup options for how the thermostat will function, along with choosing your
particular system type, are performed using a menu on the display screen.
TO ACCESS THE SETUP MENU: Move the System Mode switch into the OFF
position, and then hold down the SET button for approximately 5 seconds until
the screen changes. The menu will always start with item #01, and is advanced
to each following item by a single press of the SET button. The options for each
item are changed using the UP or DOWN buttons.
ITEM #01 (TEMPERATURE SCALE):
[1] (default) Shows all temperature values in Fahrenheit.
[2] Shows all temperature values in Celsius.
ITEM #02 (NOT USED):
ITEM #03 (NOT USED):
ITEM #04 (MAXIMUM HEAT SET TEMP LIMIT):
[1] (default) Limit 90F (32C). The maximum heating set temperature is 90F (32C)
degrees with no heat mode temperature restrictions.
[2] Limit 80F (27C). The maximum heating set temperature is 80F (27C) degrees.
[3] Limit 70F (21C). The maximum heating set temperature is 70F (21C) degrees.
[4] Limit 60F (16C). The maximum heating set temperature is 60F (16C) degrees.
ITEM #05 (MINIMUM COOL SET TEMP LIMIT):
[1] (default) Limit 45F (7C). The minimum cooling set temperature is 45F (7C)
degrees with no cool mode temperature restrictions.
[2] Limit 55F (13C). The maximum cooling set temperature is 55F (13C) degrees.
[3] Limit 65F (18C). The maximum cooling set temperature is 65F (18C) degrees.
[4] Limit 75F (24C). The maximum cooling set temperature is 75F (24C) degrees.
ITEM #06 (SYSTEM / EQUIPMENT TYPE):
[1] (default) Fn=Furnace. This is for the majority of heating systems such as a
natural gas furnace or hot water boiler, that are not Heat Pump systems.
[2] HP=Heat Pump. Use this setting if you have a Heat Pump system (which uses
the outdoor unit as the primary heat source). The presence of either an “O” or
“B” wire on your previous thermostat would typically indicate you have a heat
pump system. This thermostat is NOT compatible with heat pumps which also
have an electric heating element as a backup heat source (called Auxiliary /
Emergency Heat). IMPORTANT: When set to “2” for HP, the circuit board
Gas/Electric option must also be set to “ELEC”, as described earlier in the
“COMPLETE THE INSTALL” section.
18
ITEM #07 (DELAY TIME):
[1] (default) 5 Minutes. Thermostat waits 5 minutes before turning the system
back on after it was last run. The 5 minute setting is fine for most applications,
and provides equipment protection by preventing rapid cycling.
[2] Same operation as above, but reduced to 2 minutes between state changes if
desired.
ITEM #08 (TEMPERATURE SWING):
[1] (default) This is the tightest control, which is plus/minus 0.25F (0.14C)
degrees from the target set temperature.
[2 through 9] These alternate values make the temperature control wider with
more variation. Each incremental setting number adds an additional 0.25F
(0.14C) degrees onto the initial setting. [9] is the widest control setting, which is
plus/minus 2.25F (1.25C) degrees from the set temperature.
ITEM #09 (TEMPERATURE CALIBRATION):
[0 (zero)] (default) At zero, there are no changes made to the base room
temperature measurement. The adjustment is from as low as subtracting
-5F (-3C) degrees from the room temperature, to as high as adding +5F (+3C)
degrees to the room temperature. The internal temperature sensor is accurately
calibrated at the factory, and in most cases this setting should not need to be
altered.
19
OPERATING INSTRUCTIONS:
HEATING AND COOLING: Basic operation of your heating or cooling system can
be obtained by choosing either HEAT or COOL with the System Mode switch. The
temperature can be adjusted using the UP and DOWN buttons.
LCD DISPLAY BACKLIGHT: The display screen is lighted to assist viewing at
nighttime, or in locations with low light levels. A press of any button on the front
panel will light the display for approximately 10 seconds. Any button presses
that occur while the light is on will reset the 10-second timer, causing the screen
to remain illuminated for an additional 10 seconds.
STATIC NOTICE: This thermostat is protected against normal static electric
discharges, however to minimize the risk of damaging the unit in extremely dry
weather, please touch a grounded metal object before touching your thermostat.

ADVANCED FEATURES:
KEYPAD LOCKOUT: You can lock the front panel buttons to prevent unauthorized
tampering of your thermostat settings.
TO LOCK THE KEYPAD: Start with the thermostat at rest, and the display backlight
NOT illuminated. Press the SET button one time to illuminate the display screen,
then press and hold the SET button for at least five seconds until a padlock icon
appears in the display screen.
TO UNLOCK THE KEYPAD: Start with the thermostat at rest, and the display
backlight NOT illuminated. Press the SET button one time to illuminate the
display screen, then press and hold the SET button for at least five seconds until
the padlock icon disappears from the display screen.
SOFTWARE RESET: A Software Reset is used to erase ALL heating and cooling
temperature programs, and to return all user-adjustable software settings back
to their original factory default values. To perform a Software Reset, first ensure
that the thermostat’s Keypad Lockout is not enabled and then move the System
Mode switch to the OFF position. Start with the thermostat at rest, and the
display backlight NOT illuminated. Press the SET button one time to illuminate
the display screen, then press and hold the SET button for at least five seconds
until the backlight goes out and the display screen becomes fully populated with
all segments visible.
COMPRESSOR PROTECTION BYPASS: This optional feature permits the installer
or service technician to temporarily disable the built in compressor protection
delays. This is most useful for diagnosing and testing the heating and cooling
systems after installation is complete, and should not be used during normal
operation. To activate this feature, first ensure that the thermostat’s Keypad
Lockout is not enabled and then move the System Mode switch to the OFF
position. Start with the thermostat at rest, and the display backlight NOT
illuminated. Press any button one time to illuminate the display screen, then
press and hold both the UP and DOWN buttons together at the same time for at
least five seconds. NOTE: there will no visual confirmation on the display screen
when this feature becomes activated, however you should be able to turn the
cooling system on and off without any protection delays being imposed. All
compressor protection delays (in all modes of operation) will be disabled for 5
minutes. After the 5-minute duration has expired, the thermostat will return to
normal operation automatically.
21
BATTERY REPLACEMENT:
This thermostat is powered by two “AA” Alkaline batteries. The batteries should
be replaced AT LEAST once per year to ensure reliable operation (or sooner if the
battery icon or “LO BATT” appears in the display screen). The batteries are
located on the back of the thermostat’s circuit board. The front portion of the
thermostat can be removed from the back half by using the housing release tabs
on the bottom edge of the thermostat housing.
When installing new batteries, we recommend using only brand new Energizer®
or DURACELL®, “AA” size alkaline batteries. Please observe the polarity
markings shown in the battery compartment to ensure proper installation. When
finished, line up the front of the thermostat to the base, and firmly press together
to securely latch the front and back halves together properly.
