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.
F
OF
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. 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.
4. 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 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 heat (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.

HARDWARE SETUP OPTIONS:
On the thermostat’s circuit board, there is a row of DIP switches, labeled #1
through #8. The position of these switches will change how the thermostat
operates, and also how information is conveyed to you on the LCD display
screen. If you make any changes to these options, the changes are not
recognized unless you either: change the position of the HEAT/OFF/COOL
mode switch, or press the “HW RST” (Hardware Reset) button on the circuit
board. The use of this button is further
described in the “ADVANCED FEATURES”
section of this manual.
These option switches are very small and
should be moved carefully using objects
such as: eyeglass screwdriver, fine-point
pen, toothpick, or similar. The listing
below describes the available choices for
each option switch:
SWITCH #1 (SYSTEM): [OFF/RIGHT = FURN, default] This setting is used for
the majority of all heating systems that are not heat pumps. Examples for
this setting would be: natural gas furnace, hot water baseboard heat, and oil
heat. [ON/LEFT = HP] Use this setting if you have a heat pump unit (which
looks just like an outside air conditioning unit, but is used for both cooing
and heating).
SWITCH #2 (TYPE): [OFF/RIGHT = PROG, default] The thermostat controls
the room temperature by following temperature program periods that you set
up based upon your daily routine. [ON/LEFT = MAN] The thermostat
operates manually just like a mechanical or non-programmable model. This
method of operation is very basic and only shows the room temperature and
set temperature; there are no temperature programs, days of the week, or
clock times.
SWITCH #3 (PERIODS): [OFF/RIGHT = 4, default] The thermostat uses four
temperature program periods in both heating and cooling (MORN, DAY, EVE,
and NITE). Each period has a separate start time and a set temperature.
[ON/LEFT = 2] The thermostat operates in the same manner as above,
however there are only two temperature program periods for heating and
cooling (DAY and NITE). This may be more convenient if you are typically
home during the day, and only need the set temperature to be different while
you are sleeping.

17
SWITCH #4 (SCALE): [OFF/RIGHT = F, default] All temperature values are
displayed using the Fahrenheit scale. [ON/LEFT = C] This setting displays all
temperature values using the Celsius scale.
SWITCH #5 (TIME): [OFF/RIGHT = 12 HR, default] This setting displays the
clock times and temperature program period start time values on the screen
using US standard AM and PM values. [ON/LEFT = 24 HR] This setting
displays the clock and temperature program period start time values on the
screen using the 24 HR military-time format (17:30 hours, 22:00 hours,
without using AM/PM).
SWITCH #6 (DELAY): [OFF/RIGHT = 5 MIN, default] This sets the minimum
length of time that Heat or Cool must remain either On or Off, before it will
automatically switch to the alternate On or Off state. This internal delay
prevents rapid cycling of your system and provides equipment protection
particularly for cooling units. The 5-minute setting is fine for most
applications. [ON/LEFT = 2 MIN] If you feel that your system may need to
cycle more frequently than the thermostat is allowing, then you may use the
2-minute setting.
SWITCH #7 (RECOVERY): [OFF/RIGHT = DISABLE, default] The Early
Recovery feature affects how the thermostat transitions from an energy
saving setback (DAY and NITE) program period, to a comfort (MORN and
EVE) program period temperature, when it is following the daily temperature
programs. When this is disabled, the thermostat makes a set temperature
change at the beginning of an upcoming period's start time. [ON/LEFT =
ENABLE] The Early Recovery feature will calculate the capability of your
system and turn on the heating or cooling early so that the temperature in
your home reaches the desired set point as close as possible to the start of
the period. During the time that the thermostat is performing a recovery, the
words “IN RECOVERY” will be shown, alternating at the top of the display
with the current system mode.
SWITCH #8 (BATTERY MONITOR): [OFF/RIGHT = ON, default] This setting,
regularly monitors the battery level, and shows “LOW BAT” on the screen if
the batteries need to be replaced. Use this setting at all times when
batteries are present in the thermostat. [ON/LEFT = OFF] This setting only
applies if you are NOT physically using batteries in the thermostat, and are
powering the thermostat entirely from the system (“C” wire terminal).

18
GAS / ELEC SLIDE SWITCH (FAN OPERATION):
This switch is a physical component by itself on
the circuit board, and is much larger than the
DIP switches listed above. [DOWN = GAS,
default] This setting lets the heating system
control the blower fan automatically by itself.
Systems that would typically use the “GAS”
setting would be: natural gas, propane, or oil
furnaces. This setting has no effect upon Cool
mode operation. [UP = ELEC/HP] This setting
runs the system’s blower fan when heat is called
BATTERY
GAS
ELEC
for, and is required for heating systems that do not control their own fan
while the thermostat is in HEAT mode. Heat pump systems, and units with
an electric heating element typically require this setting.
COMPLETE THE INSTALL:
Once the hardware options are set, install two new Energizer® or DURACELL®
"AA" size alkaline batteries. Ensure that the batteries are installed in the
proper direction as per the markings shown in the battery tray. If the
batteries were already installed before changing the hardware setup options,
change the position of the HEAT/OFF/COOL System Mode switch to accept
the new hardware option switch settings.
FRONT PANEL ITEMS:
These two items below are both located on the right side 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.

19
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).

There are on-screen indicators to show you when the thermostat is calling
for heating or cooling to occur. In the Heat mode switch position, a flame
will be present on the screen. A steady flame means that the thermostat is
not calling for your heating system to run, while a flashing flame means that
your heating system should be currently running. In the Cool mode switch
position, a snowflake will be present on the screen. A steady snowflake
means that the thermostat is not calling for your cooling system to run,
while a flashing snowflake means that your cooling system should be
currently running.
EMERGENCY HEAT: (Heat Pump Configuration Only). While in normal Heat
mode, one single press of the EMER button will activate Emergency Heat
mode. While in Emergency Heat, the top of the screen will change from
“Heat Mode” to show “Emer Heat”. A single press of the EMER button again
will end Emergency Heat, and return back to normal Heat mode. 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 Heat 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
primary 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 prevent damage to the heat pump if outside
temperatures are below the manufacturer’s recommendations. As every heat
pump has different operating characteristics, you should refer to your heat
pump literature to determine when to disable the heat pump and run in
Emergency Heat mode.

LCD DISPLAY BACKLIGHT: The display screen is lighted to assist viewing at
nighttime, or in locations with low light levels. A press of any area on the
touch panel will light the display for approximately 10 seconds. Any screen
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.
TEMPERATURE OVERRIDE: While in the Normal Run screen, the set
temperature can be temporarily changed by pressing the Set Temperature
digits, then pressing the UP or DOWN buttons. 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 words “HEAT OVRRIDE” or “COOL
OVRRIDE” will be shown in the display screen. An Override may be
cancelled by either pressing the HOLD button two times, or by moving the
mode switch to OFF, pausing briefly, then switching back to the HEAT or
COOL position. When in the Normal Run mode, the display should say either
“HEAT MODE” or “COOL MODE”.
MINIMUM RUN TIME: The thermostat has a default internal time delay of 5
minutes between load-on and load-off activations to prevent heating or
cooling system damage, which can occur from very frequent cycling. If
heating or cooling does not turn on right away with a manual change in set
temperature, please wait at least 5 minutes and the system should resume
normal operation.
TEMPERATURE HOLD: A Temperature Hold is used for maintaining a fixed set
temperature. Once a Hold is initiated, 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 words “HEAT HOLD” or
“COOL HOLD” will appear in the display. To cancel a Hold, press the HOLD
button one more time. If a mains 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.
TEMPERATURE PROGRAMS:
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.
The following examples are shown using Heat mode. Programming in Cool
mode is done in the same exact manner with the System Mode switch in the
Cool position.
SET TEMPERATURE PROGRAMS: Press the MENU button, then press the
SCROLL button until “SET/REVIEW HEAT PROGMS” is shown, then press the
OK button to enter the programming screen. Use the UP and DOWN buttons
to adjust the start time for the MORN period, then press the NEXT button to
advance. Use the UP and 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.
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 Heat temperature program. While in a
temperature programming screen, press the “COPY” button one time. The

words “COPY PROGRAM” will flash briefly at the top of the screen, followed
by “FROM” and “TO”. Under the word “FROM” will be a flashing day of the
week. Using the UP and DOWN buttons, select the day that you want to copy
from. Press the NEXT button one time. Your copy from day should now be
on steady with the day under the word “TO” 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 button will perform the copy, and the day flashing under the
word “TO” will have advanced to the next following day. You may continue
to perform short single presses of the COPY button to keep copying from the
original source day to the remaining days, one after the other. Specific days
may be skipped by pressing the UP button, to advance past them while they
are flashing under the word “TO”. Press the EXIT button to return to the
Normal Run screen.
ADVANCED FEATURES:
TEMPERATURE SWING SETTING, OFFSET SETTING, AND TEMPERATURE
CALIBRATION:
NOTE: The Swing setting, Offset setting, and Calibration settings need to be
performed in a timely manner, as the thermostat will timeout and
automatically exit these adjustment screens after approximately 10 seconds
without a button press.
SWING DESCRIPTION: 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. 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. There is only one Swing setting, and this
determines the cut-in and cut-out points for both the first and second stages
(if present), in both Heat mode and Cool mode. The swing setting range is
between #1 and #9 (0.25°F to 2.25°F, in 0.25°F degree increments (or 0.14°C
to 1.25°C, in 0.14°C degree increments for Celsius)). Swing number 1 is the
default setting.
OFFSET DESCRIPTION: This setting is shown as a number of degrees, and is
similar in nature to the Swing however this only effects the operation of the
second (auxiliary) heating stage, if present. The setting range for Offset is

24
from 0°F to 9°F degrees (0°C to 5°C degrees). When set to 0 degrees, the
second heating stage is completely disabled while in regular Heat mode
(Emergency Heat mode will still function for heat pump configurations). The
Offset value 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.

TEMPERATURE CALIBRATION DESCRIPTION: The internal temperature
sensor in this thermostat is accurately calibrated at the factory, 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.
TO CHANGE THE SWING, OFFSET, AND CALIBRATION: Press the MENU
button, then press the SCROLL button until “SET/REVIEW SWING VALUE” is
shown on the screen, then press the OK button. The words “ADJUST VALUE
SWING” will appear at the top of the screen, along with a single flashing
digit. Use the UP and DOWN buttons to change the number value from #1 to
#9. Press the NEXT button to accept the Swing setting and proceed to the
Offset setting.
After the Swing value has been accepted, the words “ADJUST VALUE
OFFSET” will appear at the top of the screen, along with a single flashing
temperature digit. Use the UP and DOWN buttons to change the number
value between 0°F and 9°F degrees (0°C to 5°C). The 0° (zero) degree
setting will disable the 2nd heating stage while in regular Heat mode. Press
the NEXT button to accept the Offset setting and proceed to the Calibration
setting.
After the Offset value has been accepted, the words “ADJUST VALUE CAL”
will appear at the top of the screen, along with a single flashing temperature
digit. Use the UP and DOWN buttons to change the number value between
–5°F and +5°F (–3°C and +3°C). The 0° (zero) degree setting is the default
value, and will not alter the displayed room temperature from the measured
reading. Press the NEXT button to accept the Calibration setting and return
back to the Swing setting. You can keep pressing the NEXT button to review
your three setting values, or press the EXIT button to return to the Normal
Run screen.
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
Download from Www.Somanuals.com. All Manuals Search And Download.
26
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.
NOTE: The Setback settings need to be performed in a timely manner, as the
thermostat will timeout and automatically exit these adjustment screens after
approximately 10 seconds without a button press.
TO START A SETBACK: Press the MENU button, then press the SCROLL
button until “TEMPERATURE SETBACK” is shown, then press the OK button.
The words “OVERRIDE LEFT” will appear at the top of the screen, along with
two digits and the word “HRS”. Use the UP and 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 “HRS” left
to “DAYS” left, with an available duration of 1 to 30 days. Once you have
selected your desired Setback duration, press the NEXT button to advance.
The display will change from “OVERRIDE LEFT” left to “OVERRIDE
TEMPERATURE”. Use the UP and DOWN buttons to select your desired Set
Temperature that will be used during the Setback duration. Once complete,
press the NEXT button to accept the setting and return to the Normal Run
screen.
TO CANCEL A SETBACK: A Setback can be cancelled by either pressing the
HOLD button two times, or by moving the mode switch to OFF, pausing
briefly, then switching back to the HEAT or COOL position. When in the
Normal Run mode, the display should say either “HEAT MODE” or “COOL
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.

27
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.
The following examples are shown for setting the maximum set temperature
for Heat mode. Setting the Temperature Limit Stop for Cool mode is done in
the same exact manner with the System Mode switch in the Cool position,
and instead you will be setting the minimum set temperature for cooling.
Once a Temp Stop Lock Code has been selected, this same code is used for
both Heat and Cool temp stops.
TO SET THE TEMPERATURE LIMIT STOP: Press the MENU button, then press
the SCROLL button until “SET HEAT TEMP STOP” is shown, then press the
OK button. The words “ENTER CODE” and “TEMP STOP” will appear at the
top of the screen, along with two digits at the left. Use the UP and DOWN
buttons to enter the current Temp Stop Lock Code (“00” by default). Press
the NEXT button to advance. If the code entered does not match the current
Temp Stop Lock Code, the words “WRONG CODE” will flash briefly, and you
may try to enter the correct code again. If the current code has been entered
correctly, you will have the ability to change the desired Temp Stop Lock
Code to something else. The words “SET CODE” and “TEMP STOP” will
appear at the top of the screen, along with two digits at the left. Use the UP
and DOWN buttons to enter the desired Temp Stop Lock Code to be used,
and press the NEXT button to advance.
The words “SET HEAT RANGE STOP” will appear at the top of the screen,
along with two large temperature digits in the middle. Use the UP and
DOWN buttons to adjust the desired maximum heat set temperature value (or
minimum set temperature value for Cool mode). Once complete, press the
NEXT button to accept the setting and return to the Normal Run screen.
IF YOU FORGET YOUR TEMPERATURE STOP LOCK CODE: The code can be
reset to the factory default “00” by performing the following steps. Start
with the System Mode switch in either the Heat or Cool positions, then
change to the OFF position. Press and hold the HOLD, NEXT, and OK buttons
all at the same time for at least 10 seconds. The screen will briefly show
“00” on the screen to confirm that the Temp Stop Lock Code has been
successfully reset to the factory default of “00”.

KEYPAD LOCKOUT: You can lock the touch-panel buttons to prevent
unauthorized tampering of your thermostat settings.
NOTE: These keypad lock instructions need to be performed in a timely
manner, as the thermostat will timeout and automatically exit the keypad lock
screens and return to the Normal Run screen after approximately 10 seconds
without a button press.
TO LOCK THE KEYPAD: The System Mode switch must be in either the Heat
or Cool position. Press the MENU button, then press the SCROLL button
until “SET KEYBOARD LOCK CODE” is shown, then press the OK button. The
words “ENTER CODE” will appear at the top of the screen, along with four
digits at the left. Select a 4-digit code that you would like to use for locking
the thermostat. Press the UP and DOWN buttons to change each digit
individually, using the NEXT button to cycle through which digit is selected.
Pressing the OK button will lock the thermostat touch panel using the 4-digit
code that is shown on the screen, and return to the Normal Run screen with
a padlock shown to confirm that the thermostat is now locked.
TO UNLOCK THE KEYPAD: Press the padlock icon, and the words “UNLOCK
KEYBOARD?” will appear at the top of the screen. Press OK to proceed with
entering the unlock code (or press the EXIT button to cancel). The words

the left. You will need to enter the proper unlock code that was used for
initially locking the thermostat. Press the UP and DOWN buttons to change
each digit individually, using the NEXT button to cycle through which digit is
selected. With the correct lock code entered on the screen, pressing the OK
button will unlock the thermostat. If the code entered does not match the
current keypad lock code, the words “WRONG CODE” will flash briefly, and
you may try to enter the correct code again.
IF YOU FORGET YOUR KEYPAD LOCK CODE: The following steps can regain
access to the thermostat. Remove the front portion of the thermostat from
the wall, and briefly press the “HW RST” HARDWARE RESET button on the
thermostat circuit board. More information about the use of this button is
described later in this section.
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.

29
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 ACCESS FILTER INFORMATION: Press the MENU button, then press the
SCROLL button until “SET/REVIEW FILTER USAGE” is shown, then press the
OK button. The words “FILTER USAGE COUNT” will appear at the top of the
screen, along with the total number of hours that have elapsed since the last
time the filter counter was reset. Press the NEXT button to advance.
The words “FILTER USAGE RESET?” will appear at the top of the screen. To
reset the filter counter to the start of the current limit setting press the OK
button. Press the NEXT button to advance.
The words “ADJUST VALUE FILTER LIMIT” will appear at the top of the
screen. This shows the current setting value for how many filter run time
hours can elapse before showing “CHANGE FILTER” in the Normal Run
screen. The adjustment range for this setting is from 0 hours to 2000 hours,
with 720 hours as the default. A filter limit setting of 0 (zero) hours will
disable the filter monitor feature. Once complete, press the EXIT button to
save all settings and return to the Normal Run screen.
NOTE: Air filters are sold based upon how many days they are rated for. One
day of filter run time is actually considered only 8 hours (not a full 24, since
your heating and/or cooling system only runs for approximatly one third of
the time). For a “90-day” filter, use a limit setting of 720 hours should be
used, and for a “30-day” filter, a limit setting of 240 should be used.
ENERGY USAGE MONITOR: Your thermostat contains a timer, which records
the amount of “on-time” for your heating and cooling systems. There are
three records that can be displayed for both Heat and Cool modes:
1) The amount of system run time so far for today.
2) The amount of system run time for yesterday.
3) The total cumulative system run time since the timer was reset.
The Heat Energy Usage information is shown while the System Mode switch
is in the Heat position, and the Cool Energy Usage information is shown
while the System Mode switch is in the Cool position. The following

examples are shown for viewing the Energy Usage while in Heat mode.
Viewing the Cool mode information is done in the same exact manner in Cool
mode.
TO VIEW THE ENERGY USAGE TIMERS: Press the MENU button, then press
the SCROLL button until “REVIEW HEAT ENERGY USAGE” is shown, then
press the OK button. The words “TODAYS ENERGY USAGE” will appear at
the top of the screen, along with the amount of heating system runtime
(displayed as “HH:MM”, for hours and minutes). Use the NEXT button to
cycle between Today’s Usage, Yesterday’s Usage, and the Total Cumulative
Usage for heat mode. NOTE: For the Total Cumulative Usage, the timer will
record up to a maximum of 99 hours and 59 minutes, then the display will
change to “HHHH” for hours only, without the colon in the center.
Pressing NEXT after the Total Cumulative Usage will show the words “TOTAL
USAGE RESET?” at the top of the screen. Pressing OK at this screen will
clear the Heat Energy Usage timer, and start back at 0 (zero). Press the EXIT
button to return to the Normal Run screen.
HARDWARE RESET: The Hardware Reset button (labeled
“HW RST”) is a small round push button that is located
HW
RST
towards the right side of the circuit board, just below the
battery holder. Pressing this button will cause the LCD
display screen to become fully populated, the heating and
cooling load relays to cycle off, read the position of the
Hardware Setup Option switches, and will perform an internal system check
of the thermostat components. If your thermostat appears to be acting in an
erratic manner, pressing the Hardware Reset button may remedy this
behavior. The temperature programs are not erased when a hardware reset
is performed, however the clock will have to be changed to match the
current day and time.
SOFTWARE RESET: The Software Reset button (labeled
“SW RST”) is a small round push button that is located
SW
RST
towards the right side of the circuit board, just below the
battery holder. A Software Reset is used to erase all
heating and cooling temperature programs, and any user-
adjustable software values such as: Swing, Offset, and
Calibration, to their original factory default values. To perform a Software

Reset, press and hold the Software Reset button for at least 5 seconds. The
LCD display screen will become fully populated, then return to normal. The
thermostat will still retain the current day and time even after a Software
Reset has been performed.
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, start with the System
Mode switch in either the Heat or Cool positions, then change to the OFF
position. Press and hold the OK button for at least 5 second. The
thermostat will give a single beep sound to confirm that this feature has
been activated. 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.
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 “LO-BATTERY” icon appears at the bottom of the display
screen). The batteries are located on the back of the thermostat, at the top
of the circuit board. The front portion of the thermostat can be removed
from the back half by pulling straight outwards on the top and bottom of the
thermostat housing, at the large indentations that are present in the center
of the top and bottom edges.
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.
