4.1 TOOLS REQUIRED
• #1 Phillips screwdriver (small)
• Drill with 3/16-in. (4.8mm) bit
• Wire stripper/cutter
4.2 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.
• Do not locate where air circulation is poor, such
as in a corner or an alcove; or behind an open
door.
• 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 the 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 install the unit until all construction work
and painting has been completed.
• Read instructions carefully before removing
W A R N I N G:
any wiring from an existing thermostat.
• Label wires before they are removed.
• When removing wires from their terminals,
ignore the color of the wires since they may
not comply with any standard.
4.3 REMOVAL OF OLD UNIT
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 to
identification. Label and remove 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.
4.4 MOUNTING
5. Strip insulation 3/8 in. (9.5mm) from wire
ends and clean off any corrosion.
6. Fill wall opening with non-combustible
insulation to prevent drafts from affecting the
thermostat.
7. With each thumb on a release tab at the
bottom of the body, and fingers over the top of
the unit, release the unit from its base plate by
squeezing the tabs into the body.
8. Separate the unit from its base plate by pulling
the body outward at its bottom.
3
• Be careful not to drop the unit or disturb
C A U T I O N:
electronic parts.
• Leave the door closed while the body is
being removed from the base.
9. Route the wires through the open areas in the
base plate above the terminals. Hold the base
against the wall, with the wires coming through.
Position the base for the best appearance (to
hide any marks from an old thermostat). Attach
the base to the wall with the two screws
provided.
N O T E: 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.
4.5 WIRING
• Using the terminal descriptions below, wiring
diagram on page 14, and your labels, determine
the appropriate wiring for your system.
• Also Refer to the Heat Pump Cross-reference
Chart on page 15.
• If you are unsure or need assistance, call the
LUX Technical Assistance Dept. (see
ASSISTANCE
.)

4.5.1 TERMINAL DESCRIPTIONS
• See drawing on page 16 showing layout of
terminals.
G: The fan terminal is live at any time the
thermostat attempts to turn the system fan or
blower on.
O: Live at any time the unit is in Cool mode.
B: Live at any time unit is in Heat Mode.
W: Active while the thermostat is calling for
auxiliary 3rd stage of heat.
4
Y2: Active while calling for a 2nd stage of
heating/cooling.
R: Transformer, Provides Power
Y1: Active while calling for a 1st Stage of
heating/cooling.
C: Use of this terminal allows the unit to be
system powered rather than battery powered.
E: This terminal is active when the thermostat is
calling for Emergency Heat.
4.5.2 CONNECTING THE WIRES
10. Loosen wire clamp screws
just enough to slide wire under
the black top part of the clamp.
11. Connect stripped wire ends,
by trapping it between its black clamp and brass
terminal. Then tighten its terminal screw.
12. Tape the ends of any unused wires.
4.5.3 COMPLETING YOUR INSTALLATION
13. Install two new Energizer®or DURACELL
®
"AA" size alkaline batteries at this time. For
instructions, refer to BATTERIES/MAINTENANCE.
14. Configure your thermostat at this time. Refer
to SETUP OPTIONS.
15. Install your thermostat 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, rehang it from tabs and try again.
16. Turn the power back on to your heating
and/or air conditioning system.
17. 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 system and the
blower does not operate after installation,
verify that the electric/gas option in installer
set up is set to Electric, see SETUP OPTIONS.
18. Your installation is now complete.

7.2.2 FILTER LIMIT
This general rule will provide you with a good
estimate of your filter’s life in hours. Assume
that the fan will run at 1/3 duty cycle or 8 hours
per day. Common 90-day filters are then good
for 90*24/3=720 hours of use. This is the
default limit value. Setting the filter counter limit
to 0000 will disable the change filter indicator.

before using this button. (See Page 16)
7.6 TEMPERATURE VARIATION / SWING
• Your thermostat works by turning your heating
or cooling system on and off whenever the room
temperature varies a certain number of degrees
from the set-point temperature. This variation is
the "swing". Your system should cycle on about
3 to 6 times per hour. A smaller swing number
increases the number of cycles, so room
temperature is more constant. A larger swing
number decreases the number of cycles, saving
energy in most cases.
7.6.1 SWING 1 – 1st STAGE
This setting controls when the first stage of
heating or cooling turns on and off.
• In HEAT, Swing 1 sets the temperature variation
the system allows below the set temperature
before switching the first stage heat source on,
or above the set temperature before switching
the first stage heat source off.
• In COOL, Swing 1 sets the temperature
variation the system allows above the set
temperature before switching first stage of
cooling on, or below the set temperature before
switching the first stage of cooling off. To
change this value:

for a second stage. Once a second stage is
activated, it will remain on until the set
temperature has been reached. (Note: The

Heat is not adjustable, it will always equal that of

7.7 DEAD BAND
• When using Auto-Changeover, dead band
provides a disallowed temperature range between
the maximum heat set temperature and
minimum cool set temperature. Dead Band may
be set from 1 to 6 degrees. For example, with
auto-changeover active, dead band set to 3˚F and
heat set to 70˚F, the minimum allowed cool set
temperature will be 73˚F. If the cool set
temperature is lowered, then the heat set
temperature will be lowered by the same amount

1. Dashed wires are optional.
2. If an "E" wire was connected to your old thermostat, it should be re-connected to the "E" terminal on
the new thermostat, and the optional jumper between "W" and "E" should not be used. Install this optional
jumper if you would like to use auxiliary heat as an emergency heat system.
3. Optional common wire to terminal "C" allows system power to power thermostat instead of batteries.
4. Use "B" or "O" wire but not both. Refer to equipment manufacturer's instructions to determine which
one to use.
5. If a "Y" and "C" wire are both present in your system, then "C" is the common wire.
6. Warning: If a "B" wire in you system is a common wire and you connect it to the "B" terminal instead of
"C", this may cause damage to you system.
7. Use terminal "Y2" only if you have a second compressor stage.
WARNING: THIS IS A LOW VOLTAGE THERMOSTAT (24 volts). A SERIOUS RISK OF FIRE EXISTS IF
