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.
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.
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.

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).

CO ECTI G 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.
WIRI G BASE PLATE OTICE:
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.

WIRI G DIAGRAM OTES:
(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 “TEC NICAL 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.

I STALL BATTERIES I TO 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 OPTIO (“G” TERMI AL FA OPERATIO ): 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 EAT 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
EAT 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 OPTIO (FOR HEAT PUMP APPLICATIO S): 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
eat 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 EAT 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 EAT mode, and off in COOL
mode

HEAT / OFF / COOL, SYSTEM MODE SWITCH: Set this switch to EAT to control
your heating system, and COOL to control your cooling system. The OFF position
will disable both the heating and cooling units.
AUTO / O , FA 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 BUTTO : This button is used to access the temperature program settings
when in heat or cool mode, and for adjusting the day and clock while in off
mode.
EXT BUTTO : This is used when setting items such as software options, and
temperature programs. When items on the screen are flashing during
adjustments, pressing the NEXT button will cycle through which item is flashing.
HOLD BUTTO : This button activates and deactivates the manual Temperature
old feature, which maintains a fixed set temperature indefinitely without
following a program routine. This button is not used when ITEM #02 below is set
to “3” for manual non-programmable.
UP / DOW BUTTO S: 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.

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 ME U: 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 NEXT 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 (PROGRAMMI G STYLE):
[1] (default) 5/2-Day Programming. This style uses a weekday program routine
for Monday, Tuesday, Wednesday, Thursday, Friday, and a separate weekend
program routine for Saturday and Sunday.
[2] 7-Day Programming. This style uses a separate program routine for each of
the 7 days in the week. [3] Manual Non-Programmable. In this setting, there are
no program routines for the thermostat to follow and the temperature control will
be set only by the UP and DOWN buttons on the front panel.
ITEM #03 (PERIOD QUA TITY):
[1] (default) 4-Periods. Thermostat uses four periods per day (called MORN, DAY,
EVE, and NITE).
[2] 2-Periods. The thermostat uses only two periods per day (called DAY and
NITE).
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 (MI IMUM 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.

ITEM #06 (SYSTEM / EQUIPME T 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 eat Pump systems.
[2] P= eat Pump. Use this setting if you have a eat 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 eat). IMPORTANT: When set to “2” for P, the circuit board
Gas/Electric option must also be set to “ELEC”, as described earlier in the
“COMPLETE T E INSTALL” section.
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 SWI G):
[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
(0.14F) 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 CALIBRATIO ):
[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.
