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.
4.5.2 CONNECTING THE WIRES
12. Loosen wire clamp screws just enough to slide wire
under the black top part of the clamp.
13. Connect stripped wire ends, by
trapping it between its black clamp and
brass terminal. Then tighten its terminal
screw.

●
Leave the door closed while the body is being removed
from the base.
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.
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.

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.

6.2 EDITING HEAT OR COOL PROGRAMS
5.7 FAN MODES
You can change any preset times and/or temperatures to
suit your schedule for each day of the week. The four
periods each day are named Morning (MORN), Day,
Evening (EVE), and Night (NITE).
The FAN switch controls which of three fan modes your
thermostat is to use. These modes are AUTO, CLEAN,
and ON.
5.7.1 AUTO
AUTO mode runs the fan only to fulfill your heating and
cooling requirements.

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.
Programming is performed in the following order.

temperature display area once the system’s fan has run
the number of hours specified by this setting’s limit. The
presence of the word FILTER on the screen will not effect
the operation of the thermostat. If equipped, the filter is
located in your heating/cooling equipment.

7.2.2 FILTER LIMIT
●
Rotate the dial to SET DAY/TIME
.
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.
●
Simultaneously press NEXT and HOLD. The
Temperature Offset value will flash.

Select one of the 9 values from 025 to 225 with the
UP/DOWN buttons. The smallest setting of 025 provides
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.

7.7 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 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
maintaining the 3°F dead band.
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.

Select one of the 9 values from 025 to 225 with the
UP/DOWN buttons. The smallest setting of 025 provides
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.
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.
Return the SPEED DIAL® to RUN

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.
