INSTALLATION AND OPERATING INSTRUCTIONS
IMPORTANT!
• Please read all of these instructions carefully before beginning
installation.
• Label every wire terminal designation on your existing thermostat wiring
before removing your old thermostat.
• Ignore the color of the wires since they may not comply with any
standard. Please connect wires using the terminal letter designations.
Thank you for your confidence in our product. To obtain the best results from
your investment, please read and follow the installation procedures carefully, and
one step at a time. This will save you time and minimize the chance of damaging
either the thermostat or possibly your heating and cooling system. These
instructions may contain information beyond that which may be required for your
particular installation.

• This 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. You
should consult a qualified HVAC technician or an electrician if you do not fully
understand the installation instructions.

TOOLS YOU MAY NEED:
FEATURES:

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.
WARNING:
All wiring must conform to the local codes and ordinances that are in your
particular location.
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.

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. Separate new thermostat housing using your thumb and index finger. Provide
pressure in opposite directions to the release tabs on the top of the housing,
in the directions shown in the diagram shown above.
4. 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.
5. 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).

CONNECTING THE WIRES:
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.
WIRING BASE PLATE NOTICE:
This thermostat model is part of a family of similar models that have the same
general visual appearance. Even though this base plate may look the same as
base plates from other models, the wiring connections may have different
terminal letters for different purposes. Please do not interchange the back plates
and/or thermostat front halves of other similar looking models. Doing so may
cause undesired heating and/or cooling operation to occur.

WIRING INFORMATION:

WIRING DIAGRAM NOTES:
(Important, please read all notes before connecting wires)
• If the information provided in the following wiring diagrams does not clearly
represent or match your system, please refer to the “TECHNICAL ASSISTANCE”
section of this manual, and contact us before removing any of your existing
thermostat wiring.
• All of the dashed wires shown in the wiring diagrams are either optional, or
their usage depends upon your specific system type or brand. For example:
Diagram #1 shows the fan wire as optional. If your system does not have a
fan, than this terminal will not be used.
• Terminal letters shown in black represent typical wiring applications.
Depending upon the brand of your specific system or thermostat, your terminal
letters may not match exactly. Terminal letters shown in gray represent other
possible wiring designations that you might see on your existing thermostat
terminals.
• The optional “C” terminal is used for powering the thermostat by the 24-volt
system, using the System Common wire. This can be used alone, or in
addition to installing batteries as a backup. NOTE: connecting the System
Common wire to the thermostat is not necessary for heating and cooling to
function properly.
• If your old thermostat has both a “Y” and “C” wire present, then “C” is most
likely a System Common wire.
• For Heat Pump systems, you will use either the “O” terminal or the “B”
terminal on this thermostat, but not both. If your old thermostat has both an
“O” and a “B” wire present, then “B” is likely a System Common wire and may
be connected to the “C” terminal. Connecting a System Common wire to this
thermostat’s “B” terminal may damage the thermostat, and also your heating
and cooling system.
• Some Heat Pump systems have a wire for AUX electric heat (usually W2), and
also a separate wire for Emergency electric heat (usually E). This thermostat
uses the W2 terminal for both AUX and Emergency Heat. Tape off your “E”
wire, and confirm that all components function without it.
• If replacing an old thermostat that has a mechanical clock, there may be two
wires labeled as “C” for the clock power. Tape off these wires and do not
connect them to the “C” terminal of this thermostat.
