Lux Products TX9000TS Thermostat User Manual


 
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.)

into place easily, remove the body, re-hang it from
the tabs and try again.
