CAUTION:
This thermostat is protected against normal static electric
discharges; however touching a grounded metal object
before touching your thermostat will minimize the risk of
damaging the unit in extremely dry weather.
4. SELECTING A LOCATION
On replacement installations, mount the new thermostat in
place of the old one unless the conditions listed below
suggest otherwise. On new installations, follow the
guidelines listed below.
1. Locate the thermostat on an inside wall, about 5 ft. (1.5m)
above the floor, and in a room that is used often.
2. Do not locate where air circulation is poor, such as in a
corner or an alcove, or behind an open door.
3. Do not install it where there are unusual heating
conditions, such as: in direct sunlight; near a lamp,
television, radiator, register, or fireplace; near hot water
pipes in a wall; near a stove on the other side of a wall.
4. Do not locate in unusual cooling conditions, such as: on a
wall separating an unheated room; or in a draft from a
stairwell, door, or window.
5. Do not locate in a damp area. This can lead to corrosion
that may shorten thermostat life.
6. If painting or construction work has yet to be completed,
cover the unit completely or do not install it.
WARNING:
• Read instructions carefully before removing any wires from
your existing thermostat.
• 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.
F
OF
2. Remove the cover and 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 the color of the wire that is connected to it.
Using the enclosed labels, attach a label to each of your
wires so that the letter matches the marking on your
existing thermostat.
4. When they are all labeled, carefully remove the wires one
at a time, making sure that they do not fall back inside the
wall. Do not allow any of the bare wire ends to touch
each other, or any parts on the thermostat.
5. Loosen all of the screws on the old thermostat and
remove it from the wall.
6. MOUNT THE NEW THERMOSTAT
1. Strip insulation leaving 3/8 in. (9.5mm) bare wire ends
and clean off any corrosion.
2. Fill wall opening with non-combustible insulation to
prevent drafts from affecting the thermostat.
CAUTION:
Be careful not to drop the unit or disturb electronic parts.

the thumb latch at the bottom center of the unit and
swinging the body away from the base.
NOTE:
If you are mounting the base to soft material like
plasterboard or if you are using the old mounting holes, the
screws may not hold. Drill a 3/16 in. (4.8mm) hole at each
screw, and insert the plastic anchors provided.
4. Hold the base against the wall. Route the wires through
the hole below the terminal block. Position the base for
best appearance (to hide any marks from an old
thermostat). Attach the base to the wall with the two
screws provided.

CONNECTING THE WIRES
5. Wires must be trapped between the black
clamps and the brass terminals as shown
here.
6. Securely tighten all of the electrical terminal
screws, including any unused ones.
WIRING DIAGRAM NOTES:
(Important, please read all notes before connecting wires)
• If the information provided does not clearly represent your
system configuration, please refer to the “TECHNICAL
ASSISTANCE” section of this manual, and contact our
support department before removing any of your existing
thermostat wiring.

• All of the dashed wires shown in the following 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.
• The optional “C” terminal is used for powering the
thermostat by the 24 Volt system power. This can be used
alone, or in addition to installing batteries.
• If “Y” and “C” wires are both present, then “C” is most
likely a system common wire.
• For Heat Pump systems, use either the “O” terminal or the
“B” terminal, but not both. If an “O” and a “B” wire are
both present, “B” is likely a system common and may be
connected to the “C” terminal. Connecting system
common power to this thermostat’s “B” terminal may
damage the thermostat, and also your system.
• If replacing a Honeywell TM-11, tape off the “R” wire.
Connect the “B” wire to the “RH” terminal.
• 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.

8. HARDWARE SETUP OPTIONS
NOTE:
All of the settings, options, and components listed in the
following section are located on the rear of the thermostat,
on the circuit board.
GAS/ELEC. FAN OPERATION
ELECRIC
This is a plastic jumper cap, which is
JP2
labeled as JP2. This jumper must remain
installed, and can be in one of two
positions, GAS or ELECTRIC.
GAS
This setting changes how the system’s blower fan (if
applicable) is controlled while in HEAT mode, and with the
Fan switch in the AUTO position. This setting does not
affect fan operation while in COOL mode. When set to
“Gas”, the fan is controlled solely by the heating system
itself. When set to “Electric”, the fan is controlled directly
by the thermostat. NOTE: If your blower fan does not
operate properly after installation, move the Gas / Electric
option to the “Electric” setting.
OPTION SWITCHES:
The following option settings are all located
within a group of small switches labeled 1
through 6 as shown, and are located in the
center of the circuit board. Changes made to
any of these switches are recognized on
initial power up, or when the front panel
Temperature Mode switch position has been
altered in any direction if the thermostat is
already being powered by batteries.

16
[1] SYSTEM MODE
This setting tells the thermostat about the type of heating
and cooling equipment that it is controlling, so that the
system is operated properly. This switch needs to be in the
OFF (NON-HP) position if you have a furnace or conventional
heating and air conditioning system. If you have a Heat
Pump system, the switch needs to be in the ON (HP)
position; this is applicable even if your heat pump system
has an auxiliary heat stage that is a gas furnace.
[2] RECOVERY
The Early Recovery feature affects how the thermostat
transitions from an energy saving setback temperature, to a
comfort temperature. Normally the change in temperature
only starts to occur at an upcoming period's start time.
With Early Recovery Disabled: If you have programmed your
thermostat for 70°F at 5:00PM, the thermostat will only
begin to heat your home back up when the time reaches
5:00PM. With Early Recovery Enabled: Using the same
scenario as above, the thermostat will calculate the best time
to turn on the heater, so that the temperature in your home
reaches 70°F as close to 5:00PM as possible. During the
time that the thermostat is performing a recovery, the words
“IN RECOVERY” will flash in the temperature portion of the
display screen. Switch position OFF is Recovery Disabled,
and ON is Recovery Enabled.
[3] DELAY
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 Delay prevents rapid
cycling of your system and provides equipment protection
for cooling units. Switch position OFF is a 5 minute delay,
and ON is a 2 minute delay. 5 minutes is the default setting,
and is good for most applications. If you feel that your
system is trying to cycle more rapidly than every 5 minutes,
you may try the 2 minute setting.

17
[4] SCALE
This setting determines how the thermostat displays all
temperatures on the screen. Switch position OFF is F°, and
ON is C°.
[5] TIME
This setting determines how the thermostat displays the
clock and all other time values on the screen. Switch
position OFF is 12 HR (US Standard), and ON is 24 HR
(Military Time).
[6] BATTERY MONITOR
This determines whether the internal battery voltage monitor
watches the condition of the batteries that are installed in the
thermostat. This setting should always remain enabled
unless the thermostat is being powered by System Power
alone, without any batteries present. Switch position OFF is
Battery Monitor On (Enabled), and Switch position ON is
Battery Monitor Off (Disabled).
WARNING:
Undesired operation may result if the battery monitor is set
to “Disabled” while this thermostat has batteries installed.
9. COMPLETING THE INSTALLATION
Once all hardware option settings are performed, install two
new Energizer® or DURACELL® "AA" size alkaline batteries
before continuing further. Ensure that the batteries are
installed in the proper direction as per the markings shown
in the battery tray. If batteries were already installed before
setting changes were performed, simply change the
Temperature Mode switch on the front panel to any other
position so that the new settings may be recognized by the
thermostat.

NOTE:
When you are finished performing your installation and setup
options, please remove the thin plastic film that is protecting
the LCD display screen on the front of the thermostat. This
plastic may or may not be present, and is evident by the
appearance of fake digits appearing on the display screen.
10. FRONT PANEL ITEMS
RESET
The RESET button is a small recessed push button that is
located right above the NEXT button behind the front door.
This button can be pushed with a pencil or the end of a
paper clip. This reset returns the heating and cooling
programs to their default Energy Star values, resets the filter
counter, and all other user changeable software options to
their default values. It is recommended that you write down
your current heating and cooling program start times and
temperatures prior to pressing the software reset button.
MODE SWITCHES
There are two mode switches on the front, a TEMPERATURE
Mode switch and a FAN Mode switch.
The TEMPERATURE Mode switch has three positions: HEAT,
OFF, and COOL. In the winter, set the switch to HEAT to
control your heating system. In the summer, set the switch
to COOL to control your cooling system. In the spring and
fall or when the windows are open, you can set the switch to
OFF to prevent heating or cooling operation.
The FAN Mode switch has two positions, AUTO and ON.
Setting the Fan switch to AUTO automatically runs your
system's blower fan as required, only during heating or
cooling activation. Setting the Fan switch to ON, runs your
system’s fan continuously, even if heating or cooling is not

needed. With the Fan switch in the ON position, the fan will
operate even when the Temperature Mode switch is in the
OFF position to provide air circulation only. When the fan is
running, the word “FAN” is displayed in the temperature
portion of the display screen.
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).
PUSH BUTTONS
There are five primary push buttons on the front of the
thermostat: The UP and DOWN arrow keys, the NEXT button,
The HOLD button, and the COPY/EMER button.
ROTARY DIAL
The LUX Speed Dial® provides an easy way to quickly
navigate between the different programming areas. This
rotary dial has five individual positions and should always
remain in the RUN position, unless a specific action is being
performed in one of the other positions.
11. OPERATING INSTRUCTIONS
SET DAY/TIME
Rotate the dial to the SET DAY/TIME position. You should
see the word SET appear in the upper left corner of the
display, along with the clock and a day of the week that is
flashing. With the day flashing, press either the UP or
DOWN buttons to make the current day flashing. Press the
NEXT button; this should cause the time to start flashing and
the day to remain on steady. Using either the UP or DOWN

buttons, adjust the clock to the current time, and make sure
that the proper AM or PM indication is observed as
appropriate. To assist with large adjustments, the clock
digits will increment rapidly in either direction if the UP or
DOWN buttons are held pressed for more than a few
seconds.
HEATING AND COOLING
Basic operation of your heating or cooling system can be
obtained by ensuring that the rotary dial is in the RUN
position, and simply moving the Temperature Mode switch to
either the HEAT or COOL position. Manual adjustment of the
set temperature can be performed at any time by using the
UP/DOWN buttons. While the words “SET TEMP” are being
displayed, you are able to adjust the set temperature to any
desired value within the normal operating range.
Prior to being set initially with your custom temperature
programs, the thermostat will follow the default Energy Star®
approved temperature programs that are preset within the
thermostat’s memory. A table of the default heating and
cooling programs is shown below:
PERIOD
HEAT MODE
COOL MODE
MORN 6:00 AM 70 °F (21 °C) 6:00 AM 78 °F (26 °C)
DAY
EVE
8:00 AM 62 °F (17 °C) 8:00 AM 85 °F (29 °C)
6:00 PM 70 °F (21 °C) 6:00 PM 78 °F (26 °C)
NITE 10:00 PM 62 °F (17 °C) 10:00 PM 82 °F (28 °C)
WAIT ICON
On the far right edge of the display screen, the words
“WAIT” may show up flashing from time to time. This Wait
indicator appears if there is currently a demand present for
heating or cooling activation, but the minimum off time delay
has not yet been satisfied. This provides protection for your
heating and cooling equipment, but lets you know that the
system will turn on shortly if it is required.

21
TEMPERATURE OVERRIDE
A Temperature Override occurs in Run mode, in either Heat
or Cool, anytime the user adjusts the set temperature to a
value that differs from the stored program temperature for
that day and time. When the thermostat is in an Override,
the word “OVERRIDE” will appear in the temperature area of
the display. The thermostat will temporarily maintain
thermal control using this new set temperature, until the
start time of the next program period is reached. At the start
of the next program period, the set temperature will return to
its programmed value for that period. To enter an Override
in either Heat or Cool mode, push either the UP or DOWN
buttons once and the set temperature will begin to flash.
Push either the UP or DOWN buttons again to the new
desired set temperature value. An Override may be cancelled
at any time by rotating the dial, changing the Temperature
Mode switch, or by initiating a Temperature Hold.
TEMPERATURE HOLD
A Temperature Hold is similar to an Override, but is used for
maintaining a constant set temperature for a longer duration.
Once a Hold is initiated, the thermostat will maintain the
Hold set temperature indefinitely. A Temperature Hold may
be used for days, weeks, or even months at a time. Press
the HOLD button once to enter a Hold, and the word “HOLD”
will appear in the temperature portion of the screen, along
with the set temperature flashing. While the set temperature
is flashing, press either the UP or DOWN buttons to adjust
the desired set temperature value. To cancel a Hold, press
the HOLD button once again, turn the rotary dial, or change
the Temperature Mode switch position. If a power loss
occurs while in a state of manual Temperature Hold, the
thermostat will return to Temperature Hold and maintain its
Hold set temperature after the power comes back on.

EMERGENCY HEAT (Heat Pump Configuration Only)
While in normal Heat mode with the rotary dial in the RUN
position, one single press of the COPY/EMER button will
activate Emergency Heat mode. A single press again will end
Emergency Heat mode, and return back to normal Heat
mode. While in Emergency Heat mode, the word “EMER”
will be shown in the temperature 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 Heat mode will prevent the first stage of your
heat pump system from turning on, and use only the “W2”
second stage heat terminal (Auxiliary Heat) as the primary
heating source. It may become too cold in some climates
for a heat pump alone to provide adequate heating without a
secondary heating device. As every heat pump has different
operating characteristics, you should refer to your heat
pump manufacturer's recommendations for when to disable
the heat pump and run in Emergency Heat mode.
NOTE:
This special Emergency Heat mode of operation only exists if
your System Mode hardware option is set to the HP (Heat
Pump) setting.
DISPLAY BACKLIGHT
Any button press will illuminate the display screen for about
12 seconds, even if the Keypad Lock is activated. Any
button press, mode switch change, or dial change while the
backlight is already illuminated, will reset the initial 12
second timeout.

23
AIR FILTER MONITOR
In systems that have a blower fan and air ducts, this feature
is to assist you with proper maintenance and periodic
replacement of the filter located in your heating or cooling
system. The Air Filter Monitor counts the duration of filter
usage that has occurred, since the last time the Filter
Monitor has been reset. The Air Filter Monitor is for
information only, and does not affect the operation of your
heating or cooling equipment. When the filter usage
duration has expired, the words “CHANGE FILTER” will
appear at the bottom of the display as a reminder while in
Run mode.
To set and use the Air Filter Monitor, turn the dial to AIR
FILTER. The display will show the amount of filter usage
remaining. To reset the usage counter, or change the filter
usage duration, press the NEXT button. “SET: FILTER DAYS”
will be displayed on the screen, along with a number of
days. The available settings are: OFF, 30, 60, 90, 120, 180,
or 365 days. If your system does not have a filter, setting
the value to OFF will prevent the “CHANGE FILTER” from
showing up on the screen. Return the rotary dial to the RUN
position when you are finished adjusting the Air Filter
Monitor settings.
12. ADVANCED FEATURES
SWING AND OFFSET SETTINGS
SWING: A thermostat works by turning your heating or
cooling system on and off whenever the room temperature
varies from the set-point temperature. The amount of this
variation is called the swing. Your system should cycle on
about 3 to 6 times per hour. A smaller swing number
increases the number of cycles per hour, so the room
temperature is more precise and constant. A larger swing
number decreases the number of cycles per hour, but can

save energy in some cases. 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), and affects both
heating and cooling. To change the Swing setting, ensure
that the System Mode switch is in the OFF position and the
rotary dial is in RUN. Press the HOLD button for at least 2
seconds. The words “SET:” and “SWING” will appear on the
screen with a single digit shown. Use the UP/DOWN buttons
to change the number value between 1 and 9 (0.25F to 2.25F,
in 0.25F degree increments). Number 1 is the default
setting. Press the NEXT button to accept the swing setting
and proceed to the OFFSET setting.

OFFSET: After the swing value has been accepted, the words
“SET:” and “OFFSET” will be shown on the screen. This
setting is shown as a number of degrees, and is similar in
nature to the swing however it only effects the operation of
the second (auxiliary) heating stage, if present. The setting
range for Offset is from 0 to 9 degrees. When set to 0
degrees, the second heating stage is disabled. A 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 cases where the second heating stage is costly to
operate when compared to the first stage.
USER TEMPERATURE CALIBRATION
The internal temperature sensor in this thermostat is
accurately calibrated at the factory and should not need to be
adjusted. 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 this thermostat to
another one or more, if multiple thermostats are used in the
same home. To change the Temperature Calibration: ensure
that the System Mode switch is in the OFF position, and the
rotary dial is in RUN. Press the COPY/EMER button for at
least 2 seconds. The words “SET:” and “CAL” will appear on
the screen with a single temperature digit shown. Use the
UP/DOWN buttons to change the number of degrees of
adjustment. 0° degrees is the default value. Press the NEXT
button to accept the setting.
PROGRAMMABLE KEYPAD LOCK
NOTE: The following examples use the default lock code of
“0000”. If you have altered the lock code to use your own
code, use that in place of “0000” in the following
instructions.
To prevent tampering with any of your settings, the front
panel buttons and rotary dial can be locked out, requiring a
