AIR FILTER MONITOR  
INSTALLATION AND  
SETUP OPTIONS  
The Air Filter Monitor counts the number of days, and the amount of usage since  
your filter has been replaced. In Run mode, the CHANGE FILTER indicator will  
appear when the remaining filter days have reached zero and the filter should be  
changed. To set and use the Air Filter Monitor, turn the rotary dial to AIR FILTER.  
Press NEXT and the Filter Days Left value will start flashing. Use the UP or DOWN  
buttons to select the number of days of filter life that your filter is rated for. Setting  
this value to OFF will disable the filter monitor. Return the dial to the RUN position  
once you are finished setting the filter life. To monitor the Filter Days Left or Filter  
Percent Left, turn the dial to the AIR FILTER position. The amount of filter life  
remaining will be shown in the clock portion of the display screen. Return the dial  
to the RUN position once you are finished viewing the filter life remaining.

to reset the unit’s clock, and read the position of all of the option switches. When  
any of the following items are changed, the hardware reset button must be pushed  
for the change to be recognized. User temperature programs are not erased when a  
hardware reset is performed.  
COMPATIBILITY  
ADVANCED FEATURES  
This thermostat can be used with most single stage 24 volt: gas, oil or electric  
heating and/or cooling systems, single stage heat pumps, or gas Millivolt heating  
systems. It cannot be used with 3-wire zone valves, 120 volt heating systems, or  
multi-stage heat pumps. Ask your dealer for other LUX thermostats to control those  
systems.

FAN  
SWING SETTING  
FURNACE MODE  
A thermostat works by turning your heating or cooling system on and off whenever  
the room temperature varies from the set-point temperature. The amount of this  
variation is called the “swing.” Your system should cycle on about 3 to 6 times per  
hour. A smaller swing number increases the number of cycles per hour, so the  
room temperature is more precise and constant. A larger swing number decreases  
the number of cycles per hour, but saves energy in most cases. To change the  
Swing setting, turn the dial to RUN mode. Hold down the NEXT button and push the  
HOLD button once, then let go of both. The words SWING and SET will appear on  
the screen with a number. Use the UP/DOWN buttons to change the number value  
between 1 and 9. Number 1 is the default setting. Press the NEXT button to accept  
the setting and return to normal Run mode.  
This is a plastic jumper cap which  
can be in one of two positions,

PROGRAMMING  
CAUTION: This thermostat is protected against normal minor static electric  
discharges, however to minimize the risk of damaging the unit in extremely dry  
weather, touch a grounded metal object before touching your thermostat.  
For all of the programming areas that are described below, this thermostat provides  
four independent periods per day for Heat mode and Cool mode, they are: MORN,  
DAY, EVE, and NITE. Each period ends at the start time of the following period. The  
programs for each Temperature mode are programmed separately. When you  
perform a Software Reset, an Energy Star® approved program is inserted into all of  
the program periods. You can use these default programs or alter any portion of  
them to suit your own preferences. When setting the program items, the value that  
is flashing is the item that you can change at that time.  
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.  
1. Locate the thermostat on an inside wall, about 5 ft. (1.5m) above the floor, and  
in a room that is used often.  
2. Do not locate where air circulation is poor, such as in a corner or an alcove, or  
behind an open door.  
MODE SWITCHES  
There are two mode switches on the front, a Temperature mode switch and a Fan  
mode switch. The Temperature mode switch has three positions: HEAT, OFF, and  
COOL. 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 the spring  
and fall or when the windows are open, you can set the switch OFF. The Fan mode  
switch has two positions, AUTO and ON. Setting the Fan mode switch to AUTO,  
automatically runs your system's blower fan as required only during heating and  
cooling activation. Setting the Fan mode switch to ON, runs your system’s fan  
continuously, even if heating or cooling is not needed, including when the  
Temperature mode switch is in the OFF position to provide air circulation only.  
SET WEEKDAY PROGRAM  
Select either HEAT or COOL with the Temperature mode switch. Rotate the dial to  
WEEKDAY PROGRAM. You will be programming all five weekdays at the same time.  
The first period is MORN. Using the UP and DOWN buttons, set the start time for  
this period, and then push the NEXT button to proceed. Now set the desired set  
temperature for the MORN period using the UP and DOWN buttons, and push NEXT  
to proceed. Now set the start time and set temperature for the DAY period,  
pushing NEXT after each to advance. Continue with these same steps to set the  
start time and set temperature for the EVE, and NITE program periods. When you  
are finished setting all four periods, you may continue pushing the NEXT button  
through all four periods to review your entries, or turn the dial to RUN if you are  
finished. These same programming steps for all four periods must be performed in  
both Heat and Cool Temperature modes independently.  
3. 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.  
4. 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.  
5. Do not locate in a damp area. This can lead to corrosion that may shorten  
thermostat life.  
NOTE:  
The Fan mode switch only works if your system provides a wire for the  
thermostat’s “G” wire terminal.  
6. If painting or construction work has yet to be completed, cover the unit  
completely or do not install it.  
WARNING:  
PUSH BUTTONS

Basic operation of your heating or cooling system can be obtained by ensuring that  
the rotary dial is in the RUN position, and simply moving the Temperature mode  
switch to either the HEAT or COOL position. Prior to being set initially with your  
custom temperature program, and also after a Software Reset, the thermostat will  
follow the default Energy Star® approved temperature routines that are preset within  
the thermostat’s memory, as shown below.  
To replace the batteries in the thermostat,  
remove the thermostat’s body from the  
base plate attached to the wall by pressing the thumb latch at the bottom center of  
the unit and swinging the body towards you, up and away from the base. Remove  
the used batteries from the battery tray and discard appropriately.  
4. When they are all labeled, carefully remove the wires one at a time, making sure  
that they do not fall back inside the wall. Do not allow any of the bare wire ends to  
touch each other, or any parts on the thermostat.  
5. Loosen all of the screws on the old thermostat and remove it from the wall.  
Install two new Energizer® or DURACELL®, “AA” size alkaline batteries into the  
battery tray. Observe the polarity markings shown in the battery compartment to  
ensure proper installation. When finished, hang the top of the unit by the tabs at  
the top corners of 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.  
MOUNTING  
1. Strip insulation leaving 3/8 in. (9.5mm) bare wire ends and clean off any  
corrosion.

TECHNICAL ASSISTANCE  
MINIMUM RUN TIME DELAY  
If you have any problems installing or using this thermostat, please carefully and  
thoroughly review the instruction manual. If you require assistance, please contact  
our Technical Assistance department at 856-234-8803 during regular business  
hours between 8:00AM and 4:30PM Eastern Standard Time, Monday through  
Friday. You can also receive technical assistance online anytime day or night at  
technical questions, and also permits you to email your questions to our technical  
support staff at your convenience.  
3. Remove the body from the thermostat’s base by pressing the thumb latch at the  
bottom center of the unit and swinging the body away.  
This is determined by the thermostat, and controls 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 feature prevents rapid or  
short cycling, and provides compressor protection for cooling equipment. The time  
amount for this delay is fixed at 5 minutes between on or off load changes.  
NOTE:  
If you are mounting the base to 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, and insert the plastic anchors provided.  
TEMPERATURE OVERRIDE  
A Temperature Override occurs in Run mode, in either Heat or Cool, anytime the  
user adjusts the set temperature to a value that differs from the stored program  
temperature for that day and time. When the thermostat is in an Override, the word  
Override will appear in the temperature area of the display. The thermostat will  
maintain thermal control using this new set temperature, until the start of the next  
program period time is reached. At the start of the next program period, the set  
temperature will return to its programmed value. To enter an Override in either Heat  
or Cool mode, push either the UP or DOWN button once and the set temperature  
will begin to flash. Push either the UP or DOWN button to the new desired set  
temperature value. An Override may be cancelled by rotating the dial, changing the  
Temperature mode switch, or by initiating a Temperature Hold.  
4. 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.  
WARRANTY  
Limited Warranty: If this unit fails because of defects in materials or workmanship  
within three years of the date of original purchase, LUX Products Corporation will,  
at its option, repair or replace it. This warranty does not cover damage by accident,  
misuse, or failure to follow installation instructions. Implied warranties are limited  
in duration to three years from date of original purchase. Some states do not allow  
limitations on how long an implied warranty lasts, so the above limitation may not  
apply to you. Please return malfunctioning or defective units to the participating  
retailer from which purchase was made, along with proof of purchase. Please refer  
to the “TECHNICAL ASSISTANCE” section before returning thermostat. Purchaser  
assumes all risks and liability for incidental and consequential damage resulting  
from installation and use of this unit. Some states do not allow the exclusion of  
incidental or consequential damages, so the above exclusion may not apply to you.  
This warranty gives you specific legal rights and you may also have other rights  
which vary from state to state. Applicable in the U.S.A. only.  
CONNECTING THE WIRES  
5. Wires must be trapped between the black clamps and the brass  
terminals as shown here.  
6. Being careful not to overighten them, securely tighten all of the  
electrical terminal screws, including any unused ones.  
NOTE:  
TEMPERATURE HOLD  
When you are finished performing your installation and setup options, please  
remove the thin plastic film that is protecting the LCD display screen on the front of  
the thermostat. This plastic may or may not be present, and is evident by the  
appearance of fake digits appearing on the display screen.  
A Temperature Hold is similar to an override, but is used for maintaining a constant  
set temperature for a longer time duration. Once a Hold is initiated, the thermostat  
will maintain the Hold set temperature indefinitely. A temperature hold may be used  
for days, weeks, or even months at a time. To enter a Hold, push the HOLD button  
once, and the word Hold will appear in the temperature portion of the screen, along  
with the set temperature flashing. While the set temperature is flashing, push either  
the UP or DOWN button to the new desired set temperature value. To cancel a Hold,  
press and release the HOLD button once again, rotate the dial, or change the  
Temperature mode switch.
