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.
2
●
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.
●
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.
W A R N I N G:
●
Read instructions carefully before removing 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 for 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.
C A U T I O N:
●
Be careful not to drop the unit or disturb 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.
3
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
10. Using the terminal descriptions below, wiring
diagrams on pages 10-11, and your labels, determine
appropriate wiring for you system.
11. If you are unsure or need assistance, call the LUX

screw.
14. Tape the ends of any unused wires.
4.6 COMPLETING YOUR INSTALLATION
15. Install two new Energizer®or DURACELL®"AA" size
alkaline batteries at this time. For instructions, refer to
BATTERIES/MAINTENANCE.
16. Configure your thermostat at this time. Refer to
SETUP OPTIONS.
17. 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, re-hang it from the tabs and try again.
18. Turn the power back on to your heating and/or air
conditioning system.
.)
19. 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.
20. Your installation is now complete.

5.7.3 CLEAN CYCLE
LUX’s Clean Cycle®allows you to program a forced air
system to flow air through your system’s filter, cleaning
the air in your home, even when heating or cooling is not
being utilized. In CLEAN mode the fan maintains the
programmed minimum run time; it may run additional
time as required to maintain temperature control. The
algorithm used avoids additional fan time when the
minimum run time has been met over the last hour
through temperature control. Minimum fan run times are
met by running one third the hourly requirement at
twenty minute intervals. The default minimum fan run
time is 15 minutes per hour.

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. Valid entries are
from 0 to 2000hrs.

setup values into the unit’s nonvolatile memory. To ease
reprogramming later, record your thermostat’s programs and
settings in the table provided before using this button. (See
Page 12.)
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 heating or cooling turns
on and off.
●
Swing 1 sets the temperature variation that the system
allows above and below the set temperature before
switching the heating or cooling unit on and off.
To change this value:
●

the most accurate temperature control, and the system
will cycle on/off the most frequently. The largest setting
of 225 provides the widest temperature differential, and
the system will cycle on/off less frequently.
●
7.6.2 SWING 2 - 2nd STAGE
This setting controls when the second stage of heating or
cooling turns on and off. It controls the temperature
variation the system allows above and below Swing 1's
limit before calling for a second stage. Once a second
stage is activated, it will remain on until the set
temperature has been reached.

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. With autochangeover active, dead band set to 3°F and heat set to
70°F the minimum allowed cool set temperature will be

8 SETUP OPTIONS
There are five jumpers; each controls a setting depending
.
on its position. Jumpers are located on the rear of the
thermostats circuit board. For reference there a table of
settings and jumper positions printed there as well. They
are described here from J3, the rightmost jumper, to J7,
the leftmost jumper.
8.1 MINIMUM RUN TIME J3
The position of J3 sets the minimum length of time that
the thermostat must remain with HEAT or COOL 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.
8.2 CLOCK FORMAT J4
The time shown on the thermostats clock may be
displayed in 12 or 24-hour format. Set this option to your
preference.

8.4 SMART RECOVERY J6
Smart Recovery allows your HVAC system to attempt to
recover from a setback period and reach your desired
comfort temperature by the beginning of your
programmed comfort period. This jumper allows you to
choose whether to use Smart Recovery.
●
An initial Smart Recovery will start 1/2 hour before the
programmed comfort temperature.
●
Maximum Smart recovery time is one hour.
●
If enabled, Smart Recovery will initiate if:
●
Recovery is valid, from an evening setback to morning
comfort or day setback to evening comfort period
●
In Heat mode the set temperature of the comfort
period must be higher than the setback period
●
In Cool mode the set temperature of the comfort
period must be lower than the setback period
8.5 GAS/ELECTRIC MODE J7
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.
8.6 REPOSITIONING JUMPERS
Use the table on Page 12 to determine the jumper
position corresponding to the option you desire. The
table is also printed on the circuit board. If necessary
change the jumper position by pulling it straight off the
pins it covers. Replace the jumper over one pin for
OPEN, or both pins for CLOSED. When all changes have
been made, press the
HARDWARE RESET.
These jumpers are located inside the thermostat on the
rear of its circuit board. To access them remove the unit
from the wall by pressing up on the thumb latch at the
bottom of thermostat, and swinging the body up and
away to separate them.
To change a setting, the jumper must be repositioned and
a Hardware reset must be performed. See HARDWARE
RESET.
