This thermostat can be used with most 24 volt: gas, oil, Millivolt, electric heating and cooling
systems, including heat pumps with an aux/emerg heat element.
It cannot be used with: 120/240 volt heating elements (without a transformer), or on heat pumps
that have two compressor stages (Y2). Ask your dealer for other LUX thermostats to control those
systems.
• The thermostat requires batteries to operate and failure or sub-standard performance of the
batteries may impair or prevent the correct operation of the thermostat. Use Duracell
®
or
Energizer
®
alkaline batteries ONLY for all LUX thermostats requiring batteries. BE SURE TO
CHANGE THE BATTERIES AT LEAST ONCE A YEAR, or whenever you see the LO BATT indication
on the screen. Failure to follow these battery instructions could result in property damage
and/or personal injury.
• The electrical rating for this thermostat is 1.5 Amps per terminal, with a maximum total load of
3.0A for all terminals combined.
• The thermostat contains parts that may wear out through use and are susceptible to failure if
over-loaded or used in a manner other than as indicated in the documentation.
• Check unoccupied residences regularly to ensure that all systems are operating properly.
• Check any heating/air-conditioning system including this product before operation and at
regular intervals.
• Electrical interference, static electricity, failure or substandard performance of batteries, wiring
defects in the installation and/or characteristics of the connected HVAC devices may prevent
the system from regulating heating and cooling as anticipated.
• The thermostat is a sensitive device and dropping the product can cause damage to critical
components. If the product is dropped or shaken violently during transport or installation then it
should be replaced immediately.
• Persons with physical or mental limitations may not be able to promptly respond to a
malfunction of the heating/air-conditioning system.
• All residents should be made aware of the potential in any system for malfunctions that could
cause continuous heating or cooling and should be familiar with the operation and location of
the heating/cooling appliance on/off switch.
• Read the instruction manual completely before installing the thermostat. A more detailed
product manual is available on our www.luxproducts.com website. You should consult a
qualified HVAC technician or an electrician if you do not fully understand the installation
instructions.
1. Turn OFF the electricity to all heating and cooling components. Do not turn the electricity back
on until all work is completed.
2. 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.
3. 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.
Use the wiring diagrams shown on the back of this installation sheet to find the closest match to
your particular heating and/or cooling system. Please read ALL of the Wiring Diagram Notes that
are shown above the connection diagrams, to avoid causing damage to your system or the new
thermostat.
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 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).
5. 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, and be careful not to over
tighten them, as they only need to be snug.
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 MODE SWITCH: When this switch is in AUTO, the blower fan (if present in your
system) will automatically cycle on and off by itself while 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 when the System Mode switch is in the OFF position.
NOTE: The Fan Mode switch only works if your system provides a wire for the thermostat’s “G”
wire terminal, to control a blower fan. The Fan Mode switch has no effect in systems that do not
have a blower fan (such as a hot water radiator system).
On the thermostat’s circuit board, there is a row of DIP switches,
labeled #1 through #7. The position of these switches will change
how the thermostat operates, and also how information is conveyed
to you on the LCD display screen. If you make any changes to
these options, the changes are not recognized unless you either:
change the position of the HEAT/OFF/COOL mode switch, or press
the “HW RST” (Hardware Reset) button on the circuit board.
These option switches are very small and should be moved carefully
using objects such as: eyeglass screwdriver, fine-point pen,
toothpick, or similar. The listing below describes the available
choices for each option switch:
SWITCH #1 (SYSTEM): [OFF/RIGHT = FURN, default] This is for the majority of heating systems
that are not Heat Pumps, such as a gas furnace or hot water boiler. [ON/LEFT = H/P] Use this
setting if you have a Heat Pump system, which uses the outdoor unit as the primary heat source
and may also contain an electric heating element as a backup heat source. When set to “HP”,
ensure that you have also set the Gas/Elec option to “ELEC”.
SWITCH #2 (THERMOSTAT TYPE): [OFF/RIGHT = PROG, default] Use this setting for following a
daily program routine. [ON/LEFT = MAN] This setting omits the program routine and operates as
a manual style non-programmable thermostat. This is very basic and only shows the room
temperature and set temperature on the screen, with no clock.
SWITCH #3 (PERIOD QUANTITY): [OFF/RIGHT = 4, default] Thermostat uses four periods per day
(called MORN, DAY, EVE, and NITE). [ON/LEFT = 2] The thermostat uses two periods per day
(called DAY and NITE).
SWITCH #4 (TEMPERATURE SCALE): [OFF/RIGHT = F, default] Shows all temperature values in
Fahrenheit. [ON/LEFT = C] Shows all temperature values Celsius.
SWITCH #5 (CLOCK FORMAT): [OFF/RIGHT = 12Hr, default] This displays the clock times using
standard AM and PM values. [ON/LEFT = 24Hr] This displays the clock times using the military-
time format (example 22:00 hours, without using AM or PM).
SWITCH #6 (DELAY TIME): [OFF/RIGHT = 5, default] Thermostat waits 5 minutes before turning
the system back on after it was last run. This internal delay prevents rapid cycling and provides
equipment protection. The 5 minute setting is fine for most applications. [ON/LEFT = 2] Same
operation as above but reduced to 2 minutes between state changes.
SWITCH #7 (EARLY RECOVERY): [OFF/RIGHT = OFF, default] Program Set Temperature values
start to occur at exactly the period start times. [ON/LEFT = ON] Early Recovery affects how the
transition occurs when changing from the NITE to the MORN period, and when changing from the
DAY to the EVE period. The thermostat calculates how long it takes for your home to recover from
a setback on a daily basis, and turns on ahead of time in order to reach the target set point of the
next upcoming program period by the period’s start time. While in a recovery, the words “IN
RECOV” will be shown on the display screen.
GAS / ELEC SLIDE SWITCH (FAN OPERATION):
This switch is a physical component by itself on the circuit board,
and is much larger than the DIP switches listed above.
[UP = GAS, default] This setting lets the heating system control
the blower fan automatically by itself. Systems that would
typically use the “GAS” setting would be: natural gas, propane, or
oil furnaces. This setting has no effect upon Cool mode
operation. [DOWN = ELEC/HP] This setting runs the system’s
blower fan when heat is called for, and is required for heating
systems that do not control their own fan while the thermostat is
in HEAT mode. Heat pump systems, and units with an electric
heating element typically require this setting.
NOTE: If your blower fan does not operate properly after installation, try moving the Gas / Electric
option to the “Electric” setting.
Once the hardware options are set, install two new Energizer
®
or DURACELL
®
"AA" size alkaline
batteries. Ensure that the batteries are installed in the proper direction as per the markings
shown in the battery tray. If the batteries were already installed before changing the hardware
setup options, change the position of the HEAT/OFF/COOL System Mode switch to accept the new
hardware option switch settings.
Press the MENU button. The first menu item shown is “SET DAY/TIME”, press the OK button.
With the day flashing, press UP or DOWN to set the day of the week. Press NEXT and the clock
time will start flashing. Use UP or DOWN to set the time, making sure the AM/PM indication is
correct. Holding the UP or DOWN buttons will make the clock digits scroll rapidly. Press the EXIT
button to return to the Normal Run screen.
Basic operation of your heating or cooling system can be obtained by choosing either HEAT or
COOL on the System Mode switch. Touch the Set Temperature digits on the screen and they will
begin to flash. While they are flashing, the UP and DOWN buttons will be shown also, which you
can use to adjust the current Set Temperature. When the thermostat is first powered up, it will
follow a default temperature routine that is preset from the factory.
Alternatively, you can use the HOLD button to maintain a fixed Set Temperature. The HOLD button
is in the lower left corner, when in either Heat or Cool operating modes. The visual appearance of
the HOLD button will change depending upon whether or not it is currently active.
