INSTALLATION AND OPERATING INSTRUCTIONS

Thank you for your confidence in our product. To obtain the best results from your investment, please read
these instructions and acquaint yourself with your purchase. Follow the installation procedures carefully, and
save these instructions for future reference. This will save you time and minimize the chance of damaging
either the thermostat or the systems that it controls.
This thermostat can be used with most single-stage 24 volt: gas, oil or electric heating and cooling systems,
single-stage heat pumps, or gas Millivolt heating systems.
It cannot be used with: 3-wire zone valves, 120/240 volt heating elements, or multi-stage heat pumps. Ask
your dealer for other LUX thermostats to control those systems.
Screwdrivers, wire stripper / cutter, and possibly a drill with assorted bits (new installations only).
1. Turn OFF the electricity to all heating and cooling components. Do not turn the electricity
back on until all work is completed.
2. Remove the front portion of your old thermostat to expose the wiring connections.
3. Write down the letters printed near each wire terminal that is used, and also the color of
each wire that is connected to it. Self-adhesive wire labels are also enclosed.
4. Carefully remove the wires one at a time, and bend them in a manner so that they do not
fall back inside the wall. Do not allow bare wire ends to touch each other.
5. Loosen the mounting screws for the old thermostat and carefully remove it from the wall.
On replacement installations, mount the new thermostat in place of the old one unless the conditions listed
below suggest otherwise. On new installations, please follow these general guidelines:
1. Mount the thermostat on an inside wall, about 5 ft. (1.5m) above the floor.
2. Do not locate the thermostat where air circulation is poor such as in a corner, alcove, or behind a door
that is normally left open.
3. Do not locate the thermostat where unusual heating or cooling conditions may be present, such as: direct
sunlight, above a lamp, television, or radiator, or on a wall next to an exterior door or window.
4. Do not locate in a damp environment, as this can lead to corrosion that may shorten thermostat life.
5. If painting or construction work is still ongoing, cover the thermostat completely or wait until this work is
complete before installation.
1. Strip wire insulation leaving only 3/8 in. (9.5mm) bare wire ends, and clean off any corrosion present.
2. Fill the wall opening with non-combustible insulation to prevent drafts from affecting the thermostat’s
normal operation.
3. Route the wires through the opening in the new thermostat base plate, and hold the base against the wall.
Try to line up the screw holes from the prior thermostat, and install the mounting screws.
4. If the previous holes cannot be used, hold the thermostat base against the wall so that it appears straight
and level (position the base for best appearance) and mark for the new screw holes. Attach the base to
the wall using the screws provided (use the supplied plastic anchors if needed when mounting to a soft
material such as drywall).
1. When attaching the wires to the thermostat, please ensure that the bare wire ends are held ALL the way
into the terminal block while the screw is being tightened.
2. Securely tighten all of the electrical terminal screws, including any unused ones. Be careful not to over
tighten the screws, they only need to be snug.
** Complete heating and/or cooling system wiring can be found in the WIRE IDENTIFICATION AND
WIRING SCHEMATICS section of this instruction sheet. The schematics shown provide component
information for brand new installations or for unreferenced wires.
On the circuit board, there are hardware settings called “jumpers”. These settings can be changed from
their default values by removing its black cap and reinstalling the cap so that it is positioned on only one (1)
of the metal pins, and not both. A CLOSED jumper means the
black cap is on both of the metal pins, and an OPEN jumper
means the cap is on only one (1) metal pin.
HARDWARE RESET BUTTON: A change to ANY of the jumper
settings will not be recognized by the thermostat until the
white HARDWARE RESET button on the circuit board is
pressed.

WIRING TERMINAL CONNECTIONS:
SYSTEM CONFIGURATION AND SETUP OPTIONS:
JP1 (SYSTEM): [CLOSED = Furnace, default] This setting is used for the majority of all
heating systems that are not heat pumps. Examples for this setting would be: natural
gas furnace, hot water baseboard heat, and oil heat. [OPEN = Heat Pump] Use this
setting if you have a heat pump unit (which looks just like an outside air conditioning
unit, but is used for both cooing and heating).
JP2 (DELAY): [CLOSED = 5 Minutes, default] This setting changes the length of time
that the system must remain either on or off before it will switch to the alternate on or
off state. The main purpose of this setting is to provide equipment protection by
preventing brief or undesirable frequent on/off cycling. [OPEN = 2 Minutes] This can be
used to decrease the minimum amount of time that occurs between cycles, and may be
desired for hot water radiator systems to reduce overshoot.
JP3 (SCALE): [CLOSED = Fahrenheit, default] All temperature values are displayed in F˚
degrees. [OPEN = Celsius] This setting displays all temperature values in C˚ degrees.
JP4 (FAN): This option is located separately from the first three settings shown above.
[CLOSED = Gas, default] This setting lets the heating system itself control the blower
fan automatically. Types of systems that would typically use the “Gas” fan setting would
be: natural gas furnace, propane furnace, and oil furnace. [OPEN = Elec] This setting
runs the system’s blower fan when heat is called for, and is required for systems that do
not control their own fan while in HEAT mode. Heat pump systems, and units with an
electric heating element typically require this setting.
HEAT / OFF / COOL, SYSTEM MODE SWITCH: Set this switch to HEAT to control your heating system, and
COOL to control your cooling system. The OFF position will disable both the heating and cooling units.
AUTO / ON, FAN SWITCH: When this switch is in AUTO, the blower fan (if present in your system) will
automatically cycle on and off by itself when heating or cooling is running. When in the ON position, the
blower fan will run constantly with or without a demand for heating or cooling, even in OFF mode.
UP AND DOWN BUTTONS: While in HEAT or COOL mode, you can use the UP and DOWN buttons to raise or
lower the set temperature. When the thermostat is powered up for the first time, it will use the default set
temperatures of 68°F (20°C) for Heat mode and 72°F (22°C) for Cool mode. NOTE: when you adjust the
temperature using UP and DOWN buttons, the change occurs immediately and you do not
have to press the
SAVE button to accept the changes.
SAVE BUTTON: Reducing the amount of heating and cooling energy you use will directly save you money.
The SAVE feature allows you to use just one button press to easily decrease the current set temperature by
5F (3°C) degrees while in Heat mode (or raise the set temperature by 5°F (3°C) degrees while in Cool mode).
When you leave the house, simply press the SAVE button one time to put the thermostat into Save mode, and
the word “SAVE” will be shown on the screen. When you return home, press the SAVE button again to cancel
the Save mode and return back to the previous set temperature that you were using originally.
After Save mode has been started, you can adjust the energy-saving set temperature by using the UP and
DOWN buttons in either direction. Just like above, one more press on the SAVE button will cancel the Save
mode and return back to the original set temperature that was used prior to starting Save mode.
LCD DISPLAY BACKLIGHT: The display screen has a light that will assist viewing at nighttime, or in low
lighting areas. When any front panel button is pressed, the screen will light up for approximately 10
seconds. Any button presses that occur while the backlight is on, will reset the 10 second timer, causing the
screen to remain illuminated for an additional 10 seconds.
STATIC NOTICE: This thermostat is protected against normal minor static electric discharges, however to
minimize the risk of damaging the unit in extremely dry weather, please touch a grounded metal object
before touching your thermostat.
TEMPERATURE SWING: The amount of temperature variation between load-on and load-off is changed by
adjusting the swing setting. The default value for this thermostat is #4, and the adjustment range is from #1
to #9. A smaller swing number makes the temperature control more precise and constant, and increases the
number of cycles per hour. A larger swing number will produce a greater variation between load-on and
load-off events, and decreases the number of cycles per hour.
To adjust the Swing setting: Set the thermostat to OFF mode using the System Mode switch, and hold down
the SAVE button for at least 5 seconds. When the screen changes to a single digit, this is the current Swing
setting value and it can be adjusted using the UP or DOWN buttons. The thermostat will return back to the
normal Run mode screen if no buttons are pressed for 4 seconds.
TEMPERATURE CALIBRATION: This thermostat is accurately calibrated at the factory, and in most cases
alteration to this setting should not be required. The Calibration feature allows you to manually offset the
room temperature measurement by as much as plus or minus 5°F (3°C) degrees from its original value. 0°F
(0°C) is the default setting.
To adjust the Calibration setting: Set the thermostat to OFF mode using the System Mode switch, press both
the UP and DOWN together for at least 2 seconds. When the screen changes to a single digit, this is the
current Calibration setting value and it can be adjusted using the UP or DOWN buttons. The thermostat will
return back to the normal Run mode screen if no buttons are pressed for 4 seconds.
This thermostat is powered by two “AA Alkaline batteries. The batteries should be replaced AT LEAST once
per year (or sooner, if the “LOW BAT” battery symbol appears in the display screen). When the LO BAT
symbol is shown, the temperature digits will also display the word “Lo”. The batteries are located on the
back of the circuit board, and can be accessed by pulling the front portion of the thermostat straight
outwards and removing it from the wall. When installing new batteries, we recommend using only brand new
Energizer
®
or DURACELL
®
, “AA” size alkaline batteries. Please observe the polarity markings shown in the
battery compartment to ensure proper installation. When finished, line up the front of the thermostat to the
base, and firmly press together.

Chuck McMillanMay 13, 2024

To whom it may concern: I have a Model Lux DMH 110 thermostat installed. I need to know how to set the temperature for heat and cool. Do I set it in the heat side with the slider first, and set the temperature for heat first, then set it to cool side with the slider for the central-air? Or do I just set it at one temperature and it takes care of both heat and cool both no matter if i set it on heat or cool with the slider. What is the Save button for.....and how does this factor into the settings? I'm not getting this right at all and need help either with a manual or help from Lux Corporation. Thank you for your kind attention and consideration towards this matter. Sincerely, C.J.
