CAUTIONS AND WARNINGS:
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 2.0A
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.
REMOVAL OF OLD THERMOSTAT;
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.
INSTALLATION OF NEW THERMOSTAT:
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.
COMPLETE THE INSTALL;
INSTALL BATTERIES INTO THERMOSTAT: Install two brand new Energizer' or DURACELL* "AA" size
alkaline (only) batteries, into the thermostat's battery compartment. Ensure the batteries are installed
in the proper direction.
GAS / ELEC CIRCUIT BOARD OPTION ("G" TERMINAL FAN OPERATION): This setting is a plastic
Shorting cap called a jumper. This jumper must remain installed, and set to either GAS or ELECTRIC for
your system to work properly. This setting changes how your system's blower fan (if applicable) is
controlled while the thermostat is in HEAT mode, and the Fan switch is in the AUTO position. This
setting does not affect the fan operation while the thermostat is in COOL mode.
