Push in the RESET key. This sets the
built-in heating and cooling programs. To
review the built-in programs,press NEXT
or PREVIOUS repeatedly; when you are
done, press RETURN.
You can use the built-in programs as
shown, or change them as you wish.
Each day is divided into four periods.
Each period has its own starting time and
temperature.
• The Unit can be used with most 24 volt gas, oil or electric heating and air conditioning
systems, single-stage heat pumps or gas millivolt heating systems. It cannot be used with 120
volt heating systems or multistage heat pumps. Ask your dealer for other LUX thermostats to con-
trol those systems.
•
The Unit is programmable.
There are four programming periods per day. Each period can be pro-
grammed separately.
• You can use the built-in time/temperature programs, or alter them to suit your schedule. The
Unit provides separate programming for every day of the week- for both heating and cooling. You
can override the programmed temperatures for as little as one programming period or for an entire
vacation.
• In cool weather, when the system switch is set to HEAT, the Unit will maintain cooler “set back”
room temperatures to save energy. It will then change to warmer “comfort” settings — all auto-
matically, at specified times during the day.
• In warm weather, when the system switch is set to COOL, the Unit will maintain warmer “set
back” room temperatures to save energy. It will then change to cooler “comfort” settings - all
automatically, at specified times during the day.
• A large liquid crystal display shows time, day of the week, and room and set temperatures.
It will remind you when the filter should be changed in your blower and track your system’s energy
usage.
• Temperature swing adjustment lets you fine-tune your system for maximum comfort and
economy.
• A 4-minute minimum on/off time in COOL prevents your air conditioning system from being
damaged.
• Two Energizer® or DURACELL® “AA” alkaline batteries (not included) are used to retain your
time and temperature programs.

INSTALLATION
IMPORTANT!
Thank you for your confidence in our product. To obtain the best results from
your investment, please read these instructions and acquaint yourself with
your purchase before installing your new thermostat. Then follow the
installation procedures, one step at a time. This will save you time and
minimize the chance of damaging the thermostat and the systems it controls.
These instructions may contain information beyond that required for your
particular installation. Please save for future reference.
READ
INSTALLATION
INSTRUCTIONS
FIRST
Please read this ENTIRE instruction man-
ual carefully and completely before
beginning your thermostat installation.
TOOLS REQUIRED
#1 Phillips screwdriver (small)
Drill with 3/16-in. (4.8mm) bit
THERMOSTAT 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 install it where there are unusual heating conditions, such as: in direct
sunlight; near a lamp, radio, television, radiator, register, or fireplace; near hot water pipes in a wall;
near a stove on the other side of a wall.
3. 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.
4. Do not locate in a damp area. This can lead to corrosion that will shorten thermostat life.
5. Do not locate where air circulation is poor, such as: in a corner or an alcove; or behind an open
door.
6. Do not install the unit until all construction work and painting has been completed.
7. This thermostat does not require leveling.
CAUTION
To avoid electrical shock and
to prevent damage to the
furnace, air conditioner, and
thermostat, disconnect the power
supply before beginning work. This
can be done at the fuse box, at the
circuit breaker, or at the appliance.
OFF
REMOVING THE OLD THERMOSTAT
Switch electricity to the furnace and air conditioner OFF; then
proceed with the following steps.
1. Remove cover from old thermostat. Most are snap-on types and
simply pull off. Some have locking screws on the side. These
must be loosened.
2. Note the letters printed near the terminals. Attach labels
(enclosed) to each wire for identification. Remove and label wires
one at a time. Make sure the wires do not fall back inside the
wall.
3. Loosen all screws on the old thermostat and remove it from the
wall.
MOUNTING THE UNIT ON THE WALL
1. Strip insulation 3/8 in. (9.5mm) from wire ends and clean off any corrosion.
2. Fill wall opening with non-combustible insulation to prevent
drafts from affecting the thermostat.
3. While holding thermostat, press button on TOP of the housing
and swing the front down and away from the back plate to
separate the front and back portions.
CAUTION
Read instructions carefully
before removing any
wiring from existing
thermostat. Wires must be
labeled before they are
removed. When removing
wires from their terminals,
ignore the color of the
wires since these may not
comply with the standard.
CAUTION
Do not allow wires to touch each other or parts on thermostat. Wires must be
trapped between black spacer and brass terminal. Also, be sure to tighten securely
all 7 electrical terminal screws.
NOTE
If you are mounting the base
to a soft material like plaster-
board 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 location, and insert the
plastic anchors provided.
Then mount the base as
described below.

TEMPORARY TEMPERATURE OVERRIDE
MANUAL TEMPERATURE HOLD
Use the Temp UP and Temp DOWN buttons
to initiate the temporary override. The word
“Override” will be displayed on the screen
while this is in effect (as shown to the right).
TEMP
TEMP
This feature lets you temporarily change the current set temperature without changing the pro-
grams stored in your thermostat’s memory. This setting is considered “temporary”, because the
stored program temperature will again take over at the next scheduled program period.
Note: If you have already altered the set temperature, and then use the Temp UP and Temp
DOWN buttons and return the set tempere to the same value as the current program tempera-
ture, the override will be terminated and the “Override” indicator on the screen will turn off. An
override may also be canceled by pressing the RETURN button.
To initiate a Manual Temperature Hold, start by
changing the set temperature using the Temp
UP and Temp DOWN buttons to your desired
“holding” temperature (just as in a temporary
temperature override above). Now press the
HOLD button. The word “Hold” will be displayed on the screen while this is in effect (as
shown in the drawing to the right). While Hold is being shown on the screen, the tem-
perature will remain at the set temperature until the hold is canceled by the user.
To cancel an existing hold, you can either push the HOLD button again, or push the RETURN but-
ton. When the “Hold” indicator disappears from the screen, the hold will be canceled and the
thermostat will be back in normal “Run” mode and follow the programs stored in memory.
This feature lets you manually change the current set temperature for an indefinate amount of
time without having to change the programs stored in your thermostat’s memory. This will, in
effect, make the thermostat “act” like a non-programmable unit as long as it remains in the
HOLD mode.

TEMPERATURE SWING
A thermostat woks by turning your heating or
coooling system on and off whenever the
room temperature varries a certain number of
degrees from the set point temperature. This
amount of variation above and below the set
point is called the “swing” amount.
Your system should cycle on approximately 3
to 6 times per hour. A smaller swing number
setting increases the number of cycles per
hour, which has an end result of making the
room temperature more constant and precise.
A larger swing number setting decreases the
number of cycles per hour. This will make the
room temperature vary a larger, however this
will provide an energy savings in most cases.
Press these two buttons simultaneously, and
then release to display the current setting.
The default setting of #4 will usually work fine
in most installations. This setting is consid-
ered to be optional, and you are not required
to change this setting in order to operate your
heating and cooling systems.
