CAUTION:
• The TX9000TS is protected against normal static
electric discharges. However, in extremely dry weather
you should touch a grounded metal object before the
TX9000TS to minimize the risk of causing damage to the
unit.
• Your thermostat is a precision instrument. Please
handle it with care.
2. COMPATIBILITY
The TX9000TS 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 3 wire zone
valves, 120V systems, or multistage systems.
Ask your dealer for other LUX thermostats to
control those systems.
3. INSTALLATION
Please read all instructions carefully before
beginning installation.
WARNING:
• Your thermostat is a precision instrument. Please
handle it with care.
• All wiring must conform to local codes and
ordinances.
• Turn off electricity to the appliance before installing or
servicing thermostat or any part of the system. Do not
turn electricity back on until work is completed.
• This thermostat is designed for use with 24 volt and
millivolt systems. The thermostat should be limited to a
maximum of 1.5 amps; higher amperage may cause
damage to the thermostat.
• Do not short (jumper) across electric terminals at
control on furnace or air conditioner to test the system.
This will damage the thermostat and void your warranty.
3.1. TOOLS REQUIRED

3.2. 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.
• Locate the thermostat on an inside wall, about 5
ft. (1.5m) above the floor, in a room that is used
often.
2
#1 Phillips screwdriver (small)
Drill with 3/16-in. (4.8mm) bit
Wire stripper/cutter
• 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.
• 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.
• Do not locate in a damp area. This can lead to
corrosion that will shorten thermostat life.
• Do not locate where air circulation is poor, such
as: in a corner or an alcove; or behind an open
door.
• Do not install the unit until all construction work
and painting has been completed.
CAUTION:
• Read instructions carefully before removing any
wiring from existing thermostat.
• Wires must be labeled before they are removed.
• Do not allow wires to touch each other or parts on
thermostat.
• When removing wires from their terminals, ignore the
color of the wires since they may not comply with any
standard.
3.3. REMOVING THE OLD THERMOSTAT
1. Switch electricity to the furnace and air
conditioner OFF; then proceed with the following
steps.
2. 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.
3. 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.
4. Loosen all screws on the old thermostat and
remove it from the wall.
3.4. MOUNTING THE TX9000TS
5. Strip insulation leaving 3/8 in. (9.5mm) bare
wire ends and clean off any corrosion.
6. Fill wall opening with non-combustible
insulation to prevent drafts from affecting the
thermostat.
CAUTION:
Be careful not to drop the body or disturb electronic
parts. Leave the cover closed while the body is being
removed from the base.
7. Press up on the
thumb latch at the
bottom of thermostat
and separate the
body from its base.
8. 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.
NOTE:
If you are mounting the base to a 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 location, and insert the plastic
anchors provided. Then mount the base as described
below.
3.5. CONNECTING THE WIRES
9. Loosen wire clamp screws just
enough to slide wire under the
black top part of the clamp.
10. Using your label, and
diagrams below determine
appropriate wiring for you system.
11. If you are unsure or need assistance, call the
LUX Technical Assistance Dept. (see technical
assistance.)
12. Slide proper wire between the brass back and
black top clamp.
13. Tighten each screw securely.
3.6. WIRING DIAGRAMS
See Pages 9-11 for diagrams.
3.7. COMPLETING YOUR INSTALLATION
14. Install two(2) Energizer or DURACELL "AA"
size alkaline batteries at this time.
instructions, see "BATTERIES &
MAINTENANCE".
15. Initially, your thermostat will display "SUN
12:00 AM".
"Setting the DAY and TIME" in the "OPERATING
INSTRUCTIONS" section of this manual.
16. Install your TX9000TS on its base. To do this
hang the top of the unit by the tabs on the base,
then snap the bottom of the unit into place. Do not
use unnecessary force. If the body does not snap
into place easily, remove the body, re-hang it from
the tabs and try again.
17. Turn the power back on to your heating
and/or air conditioning system.

18. Verify that the system and its fan are
operating properly. When set to a high
temperature, the heating system should provide
warm air after a short time. Likewise a cooling
system should provide cool air after a short time.
Usually sound from the furnace and air
conditioning units can be heard while they are
running. The rush of moving air should be heard
within a short time after either has been started.
NOTE:
If you have an electric heat system and the blower
does not operate after installation, see figure in
Section 7 to find the electric/gas heat jumper on the
back of the body. Move the jumper to the ELEC
position.
19. Your installation is now complete.
4. OPERATING INSTRUCTIONS
The TX9000TS displays the current time and the
room temperature. It also displays the day of the
week and the current program period, MORN,
DAY, EVE, or NITE. Temperature is indicated near
the center of the display, and time is indicated on
the left. Setting and program changes can be
made with the thermostat body on the wall, or
removed from its base plate.
4.1. SYSTEM MODE SWITCH
The SYSTEM MODE SWITCH has three positions
HEAT, OFF and COOL. Each sets the corresponding
operating mode. In the winter, set the system
switch to HEAT to control your heating system. In
the summer, set the switch to COOL to control
your air conditioner. In spring and fall or when the
windows are open, you can set the switch to OFF.
When thermostat is in the OFF position, neither
HEAT or COOL programs will run.
4.2. FAN MODE SWITCH
The fan switch has two positions; AUTO will only
run your system’s fan as required for heating and
cooling. ON runs your system’s fan continuously.
4.3. UP/DOWN CHANGE ARROW KEYS
While operating the TX9000TS there will often be
two arrow keys visible (just to the right of the
temperature) one pointing up and the other
pointing down. They are used to adjust
temperatures and change other settings.
4.3.1. TEMPERATURE ADJUSTMENT
Touch the displayed temperature once then touch
the UP/DOWN arrow key; it adjusts the flashing
set temperature by one degree in the associated
direction. Holding the key will automatically
advance the setting in the associated direction.
