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 windo w.

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 on the top of the housing,
in the directions shown in the diagram shown above.

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).

INSTALL THERMOSTAT BASE:

THERMOSTAT TOP VIEW

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 ha ve 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 INFORMATION:

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.

• For Heat Pump systems, you will use either the “O” terminal or the “B”
terminal on this thermostat, but not both. 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.

• Some Heat Pump systems have a wire for AUX electric heat (usually W2), and
also a separate wire for Emergency electric hea t (usually E). This thermostat
uses the W2 terminal for both AUX and Emergency Heat. Tape off your “E”
wire, and confirm that all components function without it.

• 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.

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.

These items below are all located behind the door on the front of the thermostat.
To open the door, pull outwards using the small indentation in the center of the
top edge of the thermostat housing.

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).

MULTI-FUNCTION, SET SLIDE SWITCH: This switch provides an easy way to
quickly access the most commonly used thermostat settings. This switch has 5
individual positions, and unless a specific setting is being adjusted, this switch
should always remain in the RUN position for the thermostat to control the room
temperature. The other Set Slide switch positions are described in greater detail
in the ADVANCED FEATURES section. NOTE: this switch is only operable when the
thermostat is in “Programmable” mode. When the thermostat is used in
“Manual” control mode, all 5 of the switch positions will act like the RUN
position, except the “FILT/ENRGY” position.

SETBACK BUTTON: This button activates and deactivates the SETBACK feature,
which overrides the set temperature for an adjustable duration. This feature is
described in greater detail in the ADVANCED FEATURES section.

COMPLETE THE INSTALL:

FRONT PANEL ITEMS:

UP / DOWN BUTTONS: The UP and DOWN buttons are used to adjust any item
that can be changed by the user. Examples are the set temperatures, clock
times, and days of the week. In many cases, an item may be flashing if it can
currently be adjusted.

HOLD BUTTON: This button activates and deactivates the manual Temperature
Hold feature, and is also used for activating and deactivating the Special
Program feature. These features are described in greater detail in the
OPERATING INSTRUCTIONS and ADVANCED FEATURES sections.

COPY / EMERG BUTTON: While setting temperature programs, this button allows
you to quickly copy settings from one day to another. When in Normal Run mode,
the usage of this button varies depending upon your specific system
configuration. For heat pump systems, pressing this button enables your
emergency hea t function, which is described in greater detail in the OPERATING
INSTRUCTIONS section. For conventional systems, there is no such thing as
emergency hea t, so this button will have no effect.

NEXT BUTTON: This button is mostly used while setting items such as software
options, and temperature program periods. When there are several items on the
screen that can be changed, usually one of them is flashing indicating that it can
be adjusted. Pressing the NEXT button will cycle through which item is flashing.

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 EMER button for approximately 5 seconds until
the screen changes. The menu will always start with item #1, 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 (CLOCK FORMAT): [12Hr, default] This displays the clock times using
standard AM and PM values. [24Hr] This displays the clock times using the
military-time format (example 22:00 hours, without using AM or PM).

ITEM #02 (TEMPERATURE SCALE): [F, default] Shows all temperature values in
Fahrenheit. [C] Shows all temperature values Celsius.

19

SYSTEM CONFIGURATION AND SETUP OPTIONS:

ITEM #03 (THERMOSTAT TYPE): [PROGRAMMABLE, default] Use this setting for
following a daily program routine. [MANUAL] This setting omits the program
routine and operates as a manual style non-programmable thermostat. This is
ver y basic and only shows the room temperature and set temperature on the
screen, with no clock.

ITEM #04 (PERIOD QUANTITY): [4P, default] Thermostat uses four periods per
day (called MORN, DAY, EVE, and NITE). [2P] The thermostat uses two periods per
day (called DAY and NITE).

ITEM #05 (EARLY RECOVERY): [OFF, default] Program Set Temperature values
start to occur at exactly the period start times. [ON] Early Recovery affects how
the transition occurs when changing from the NITE to the MORN period, and
when changing from the DAY to the EVE period. The thermostat calculates how
long it takes for your home to recover from a setback on a daily basis, and turns
on ahead of time in order to reach the target set point of the next upcoming
program period by the period’s start time. While in a recovery, the word
“RECOV.” will be sho wn on the display screen.

ITEM #06 (SYSTEM MODE): [FURN, default] This is for the majority of heating
systems that are not Heat Pumps, such as a gas furnace or hot water boiler. [HP]
Use this setting if you have a Heat Pump system, which uses the outdoor unit as
the primary heat source and may also contain an electric heating element as a
backup heat source.

ITEM #07 (FAN “G” TERMINAL OPERATION): This setting changes how your
system’s blower fan (if applicable) is controlled while the thermostat is in HEAT
or EMERG HEAT mode, when the Fan switch in the AUTO position. This setting
does not affect the fan operation while in COOL mode. When ITEM #06 is set to
"HP", this option is automatically set to "ELEC" and is not present in the settings
menu.

[GAS, default] 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.

[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, try changing
the GAS / ELEC option to the “ELEC” setting.

20

ITEM #08 (DELAY TIME): [5, default] Thermostat waits 5 minutes before turning
the system back on after it was last run. This internal delay prevents rapid
cycling and provides equipment protection. The 5 minute setting is fine for most
applications. [2] Same operation as above but reduced to 2 minutes between
state changes.

ITEM #09 (TEMPERATURE SWING): A thermostat works by turning your heating
or cooling system on and off whenever the room temperature varies from the
desired set-point temperature. The amount of this variation is called the swing.

Use the UP/DOWN buttons to change the number value between 1 and 9.
Generally your system should cycle on about 3 to 6 times per hour. A smaller
swing number makes the system cycle more frequently, so the room temperature
is more precise and constant. A larger swing number will make the system
remain on for a longer duration each time and decreases the number of cycles
per hour.

ITEM #10 (STAGE-2 OFFSET): [2, default] This setting is adjusted as a number
from 0 to 9. When set to 0 (ZERO), the second heating stage is completely
disabled while in regular Heat mode (however Emergency Heat mode will still
function for heat pump configurations). An Offset value from 1 to 9 degrees will
determine the number of degrees from the set point that will be required for the
second heating stage to turn on. This setting can be used to conserve energy in
situations where the second heating stage is more costly to operate when
compared to the first stage.

SET DAY AND TIME: Place the Set Slide Switch into the DAY/TIME position. With
the day flashing, press UP or DOWN to set the day of the week. Press NEXT and
the clock time will start flashing. Use UP or DOWN to set the time, making sure
the AM/PM indication is correct. Holding the UP or DOWN buttons will make the
clock digits scroll rapidly. Return the Set Slide switch to the R UN position when
finished.

HEATING AND COOLING: Basic operation of your heating or cooling system can
be obtained with the Set Slide Switch in the RUN position and choosing either
HEAT or COOL on the System Mode switch. The temperature can be adjusted
using the UP and DOWN buttons. When the thermostat is first powered up, it will
follow a default temperature routine that is preset from the factory (shown
below).

EMERGENCY HEAT: (Heat Pump Configuration Only). While in normal Heat mode
with the Set Slide switch in the RUN position, one single press of the COPY/EMER
button will activate Emergency Heat mode. A single press a gain will end
Emergency Hea t mode, and return back to normal Heat mode. While in
Emergency Hea t mode, the word “EMER” will also be shown in the middle portion
of the display screen. If a power loss occurs while in Emergency Heat mode, the
thermostat will continue to remain in Emergency Heat mode even after the power
comes back on.

Emergency Hea t mode will prevent the first stage of your heat pump system from
turning on, and use only the “W2” heat terminal (Auxiliary Heat) as the primar y
heating source. This will not only prevent the heat pump from wasting energy if
outdoor temperatures are too low to support efficient operation, but it could also

be temporarily changed by pressing UP or DOWN. The set temperature will return
to the programmed value stored in memory when the start time of the next
upcoming program period is reached (Morn, Day, Eve, Nite). While a Temporary
Override is in effect, the word “OVERRIDE” will be shown in the display screen.
An Override may be cancelled moving the mode switch to OFF, then back to HEAT
or COOL.

TEMPERATURE HOLD: A Temperature Hold is used for maintaining a fixed set
temperature. Once a Hold is initia ted, the thermostat will maintain the set
temperature indefinitely. A Hold may be used for days, weeks, or even months at
a time, as long as the thermostat has adequate power. To enter Hold mode:
press the HOLD button one time and the word “HOLD” will appear in the display.
To cancel a Hold, press the HOLD button one more time. If a complete power
failure occurs during a Temperature Hold, the thermostat will continue to remain
in Hold mode even after the power comes back on. NOTE: If you plan to leave
the thermostat in Hold mode for an extended duration (unattended), it is
advisable to install new Energizer

®

or DURACELL®"AA" size alkaline batteries

prior to leaving to ensure reliable operation of your heating and cooling system.

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.

By default, this thermostat has 4 separate program periods for both Heat and
Cool mode, they are: MORN, DAY, EVE, and NITE. Each period ends at the start
time of the following period. The heat programs are set in HEAT mode, and the
cool programs are set in COOL mode.

NOTE: If the thermostat is configured to use only 2 periods per day instead of 4
(HARDWARE SETUP OPTIONS), the thermostat will only use the DAY and NITE
periods. The MORN and EVE periods will not be visible on the screen.

SET TEMPERATURE PROGRAMS: Move the Set Slide switch to the TEMP PROG
position. Programming will start with Monday. Use the UP/DOWN buttons to
adjust the start time for the MORN period, then press the NEXT button to
advance. Use the UP/DOWN buttons to adjust the set temperature for the MORN
period, then press the NEXT button to advance. Now adjust the start time and
set temperature for the DAY period, pressing the NEXT button after each to
advance. Continue with these same steps to adjust the start times and set
temperatures for the EVE and NITE program periods.

When the NITE period is finished the thermostat will advance to Tuesday, with the
MORN period start time flashing. Perform the same steps that you used for
setting the Monday periods, pressing the NEXT button to advance through each
flashing value. Return the Set Slide switch to the RUN position when you are
finished.

PROGRAM COPY FEATURE: The Copy feature allows you to copy all of the
program information from any one single day, to any other day of the week. To
copy heat programs, the thermostat must be in Heat mode, and to copy cool
programs, the thermostat must be in Cool mode. Emergency Heat (heat pump
configurations only) uses the Hea t temperature program. With the Set Slide
switch in the TEMP PROG position, press the COPY/EMER button one time. The
words “COPY PROG” will briefly appear on the screen and flash once, followed by
“FRM” and “TO”. Next to FRM, a day of the week will be flashing. Using the
UP/DOWN buttons, select the day that you want to copy from. Press the NEXT
button one time. Your “copy from” day should be on steady with the “copy to”
day flashing. Use the UP and DOWN buttons to select the day that you would like
to copy to. A single short press of the COPY/EMER button will perform the Copy,
and the flashing “copy to” day will have advanced to the next following day. You

TEMPERATURE PROGRAMS:

may continue to perform short single presses of the COPY/EMER button to
proceed with copying to the remaining days, one after the other (specific days
may be skipped by pressing the UP button to advance past them when they are
flashing in the “copy to” location). To exit the Copy feature, and return to the
regular temperature program screen, press and hold the NEXT button for more
than 2 seconds. Return the Set Slide Switch to the RUN position when you are
finished.

TEMPERATURE CALIBRATION: The internal temperature sensor in this thermostat
is accurately calibrated a t the factor y, and in most cases alterations to this
setting should not be needed. The Temperature Calibration feature allows you to
manually offset the measured temperature by as much as plus or minus 5°F
(3°C) degrees from its original value. This feature can be useful to match or
synchronize this thermostat to another one or more, if multiple thermostats are
used in the same home.

NOTE: The Temperature Calibration setting need to be performed in a timely
manner, as the thermostat will timeout and automatically exit the adjustment
screen after approximately 10 seconds without a button press.

TO CHANGE THE TEMPERATURE CALIBRATION: Ensure that the System Mode
switch is in the OFF position and the Set Slide switch is in the RUN position.
Press and hold both the UP and DOWN buttons together for at least 5 seconds.
The words “SET” and “CAL” will appear in the upper right corner of the screen,
along with a single flashing temperature digit. Use the UP/DOWN buttons to
change the number of degrees of adjustment. 0° degrees is the default value,
and means no correction is being applied. Press the NEXT button to accept the
setting.

SETBACK FEATURE: The setback feature is similar to both a Temperature
Override and a Temperature Hold, in that both are used to maintain a fixed set
temperature instead of following a programmed daily routine. A Setback can be
considered the same as a Temperature Override, which can last for a longer
duration that you can adjust from 1-12 hours, or 1-30 days. By default, when a
Setback is activated in Heat mode, the set temperature used will be 5F (3C)
degrees lower than the current set temp. For Cool mode, the set temperature
used will be 5F (3C) degrees higher than the current set temp.

26

ADVANCED FEATURES:

TO START A SETBACK: Ensure that the System Mode switch is in either the Heat
or Cool position, and that the Set Slider is in the RUN position. Press and hold
the SETBACK button for at least 2 seconds. The screen will change and show the
words “HOURS LEFT” and “OVERRIDE”, along with two digits. Use the UP/DOWN
buttons to set the duration for how long you would like to maintain a fixed set
temperature (from 1 to 12 hours). If you would like to set the duration for longer
than 12 hours, keep pressing the UP button. The display will change from
“HOURS LEFT” to “DAYS LEFT”, with an available duration of 1 to 30 days. Once
your desired Setback duration is shown on the screen, you can either wait for the
screen to advance forward on its own, or press the NEXT button (behind the door)
one time to jump ahead rapidly. Now use the UP/DOWN buttons to select your
desired set temperature that will be used for the Setback duration. Just like the
previous step, you can either wait for the screen to advance on its own, or press
the NEXT button to advance and return to the Normal Run screen.

TO CANCEL A SETBACK: While in the Normal Run screen, press and hold the
SETBACK button for at least 2 seconds. The word “OVERRIDE” will disappear
from the screen and the Setback will be cancelled. Moving the System Mode
switch or Set Slide switch, will also cancel a Setback.

SPECIAL PROGRAM FEATURE: The Special Program operates in the same manner
as the normal heating and cooling programs do, however the Special Program
activation is temporar y, for a selected number of days (1-30). The Special
Program period times and temperatures can all be set to different values to
accommodate a wide variety of usa ge circumstances that may occur, such as:
being home for a couple days instead of at work, or a vacation cut short. This
feature eliminates the need to temporarily alter the normal tempera ture program
settings that continue to be used most of the time. The heat Special Program is
set in HEAT mode, and the cool Special Program is set in COOL mode. The
“number of days remaining” counter decrements by one day, every 12:00 AM
(Midnight).

NOTE: Just like the regular temperature programs, The Special Program has 4
separate periods for both Heat and Cool mode (MORN, DAY, EVE, and NITE). If the
thermostat is configured to use only 2 periods per day instead of 4 (HARDWARE
SETUP OPTIONS), the Special Program will only use the DAY and NITE periods.
The MORN and EVE periods will not be visible on the screen.

27

TO SET THE SPECIAL PROGRAM VALUES: Move the Set Slide switch to the SPEC
PROG position. The screen will display “S-PROG”. Use the UP/DOWN buttons to
adjust the start time for the MORN period, then press the NEXT button to
advance. Use the UP/DOWN buttons to adjust the set temperature for the MORN
period, then press the NEXT button to advance. Now adjust the start time and
set temperature for the DAY period, pressing the NEXT button after each to
advance. Continue with these same steps to adjust the start times and set
temperatures for the EVE and NITE program periods. Return the Set Slide switch
to the RUN position when you are finished.

NOTE: When activating the Special Program feature, button presses need to be
performed in a timely manner, as the thermostat will timeout and automatically
exit the setting screen after approximately 10 seconds without a button press.

is in effect, the clock time will alternate with the words “SPECIAL DAYS” and a
two-digit value to indicate the amount of days remaining.

TO CANCEL THE SPECIAL PROGRAM: Press and hold the HOLD button for at least
5 seconds. The “SPECIAL DAYS” will stop alternating with the clock time, and the
thermostat will now be in Normal Run mode.

TEMPERATURE LIMIT STOPS: There are two independent set temperature limit
stops: a maximum heat set temperature, and a minimum cool set temperature.
These stops do not prevent a user from performing normal actions like
Temperature Override or Hold. The Heat Limit Stop prevents the set temperature
from being adjusted higher than the heat limit setting. The Cool Limit Stop
prevents the set temperature from being adjusted lower than the cool limit
setting. Each of these temperature stops is user adjustable in one-degree
increments, and these settings are protected by a selectable 2-digit code to
prevent unauthorized tampering. By default, this 2-digit code is “00”, and the
temperature stops can be used as-is with this code.

NOTE: The Temperature Limit Stop settings need to be performed in a timely
manner, as the thermostat will timeout and automatically exit the setting screens
after approximately 10 seconds without a button press.

AIR FILTER MONITOR: In most systems that use a blower fan and air ducts, there
is an air filter that is either replaceable or requires cleaning. The filter is usually
located in the air handler, where the blower fan is. This thermostat feature
assists you with keeping track of proper maintenance and/or periodic
replacement intervals for your system’s filter.

The Air Filter Monitor counts the duration of filter usage that has occurred, since
the last time the Filter Monitor has been reset. This feature is for information
purposes only, and does not affect the operation of your heating or cooling
equipment, or the thermostat. When the filter usage duration has expired, the
words “CHANGE FILTER” will appear at the top of the display screen, alternating
with the current DAY and PERIOD.

TO SET THE AIR FILTER DURATION: Move the Set Slide switch to the “FILT/ENRGY”
position. The words “FILTER LEFT” will be shown at the top of the display
screen. Press either of the UP/DOWN buttons to select the desired filter duration
(in days) from the following choices: OFF, 30, 60, 90, 120, 180, or 365. If the
filter duration value is set to “OFF”, then the Air Filter Monitor will be completely
disabled.

TO RESET THE FILTER USAGE COUNTER: Move the Set Slide switch to the

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, press and hold both the NEXT and HOLD
buttons, while also perform a single press of the Hardware Reset button (the LCD
display screen will become fully populated). Continue to hold the NEXT and
HOLD buttons until the LCD display screen returns to normal. All compressor
protection delays (in all modes of opera tion) will be disabled for 5 minutes. After
the 5-minute duration has expired, the thermostat will return to normal operation
automatically.

33

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
phrase “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 tabs on the top 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.

BATTERY GRAPHIC: Anytime that batteries are
physically present in the thermostat, there will be
a visual indication of the remaining battery life
available on the thermostat’s display screen.
When brand new batteries are installed in the
battery compartment, this graphic should indicate
full batter y life remaining with all bars present.

Over time, as the batter y life decreases to the
point of having only 1 bar left, the Temperature
and Clock digits will start to alternate between
showing their normal content, and the words “LO
BATT”. At this point the batteries will need to be replaced as soon as practical to
avoid uninterrupted operation of your heating and/or cooling system. In most
cases, the thermostat will be capable of providing you approximately two months
of normal operation once the point of 1 bar left has been reached, and the screen
shows the words “LO BATT”.
