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.
This programmable thermostat is compatible with Single or Double pole,
120/240 VAC, line voltage electric heating systems up to 16 Amps. The
heating wattage rating is 1900 Watts (Resistive) for 120 VAC, and 3800
Watts (Resistive) for 240 VAC. This thermostat can also be used with
120/240 VAC line voltage Hydronic (hot water) heating systems with
motors up to 1/4 HP.
This thermostat cannot be used with: cooling systems, typical 24 volt
systems, or heat pump systems. Ask your dealer for other LUX
thermostats to control those systems.
NOTE: Disconnection Type: “TYPE 1B”.
Please read ALL of these instructions carefully before beginning
installation. Save them for future reference.
MOUNTING LOCATION:
Install a vertical, electrical switch box for mounting the thermostat
approximately 5 Feet (1.5 Meters) above the floor on an inside wall
where the thermostat will be exposed to average room temperature. The
use of a “deep” style switch box will make the installation easier by
providing more room for making the wiring connections. The thermostat
must be placed away from concealed warm or cold water pipes, air
ducts, or drafts from hallways, direct sunlight, fireplaces, or stairways in
order to sense room temperature properly. Do not place the thermostat
directly above any of the heating elements.
WIRING:
1. Disconnect power before removing your old thermostat (if applicable).
Double check that this thermostat is rated for the voltage and
amperage to be switched.
2. Remove the front portion of the thermostat by carefully pressing the
button at the bottom of the thermostat and swinging the body up and
away.
3. When replacing an old line voltage wall thermostat, remove it carefully
to avoid damage to the insulation on the wiring. Check the old
insulation for cracks, nicks, or fraying and apply certified electrical
tape where necessary to achieve adequate insulation, or replace the
wires in an approved fashion.
4. Use the diagrams shown in the “WIRE IDENTIFICATION AND WIRING
SCHEMATICS” section of this manual to ensure that the thermostat
connections are made to the proper wires for your installation.
5. Attach the wires together using the solder-less wire connectors
(provided), and be sure that all wire connectors are tight and secure.
6. Bend the solid conductors, and then push them and the wire
connectors into the electrical box carefully, providing enough
clearance behind the mounting screw locations. Secure the
thermostat base to the electrical box with the mounting screws.
7. Place the thermostat front portion onto the back plate by first catching
the plastic tabs at the top, and then firmly pressing the bottom of the
thermostat towards the back plate to latch the halves together.
8. Install two new Energizer
®
or DURACELL
®
"AA" size alkaline batteries
before continuing further. Ensure that the batteries are installed in the
proper direction as per the markings shown in the battery tray. The
battery tray is located in the front of the thermostat, behind the door.
9. Now turn the supply power back on to the heating system.
On the thermostat screen, ensure that the Power Unit
Disconnected Indicator (shown at right) is not present on
the display screen. If it is, remove the front half and try
mating the front half to the back half again.
The settings, options, and components
listed in this section below are located
on the rear of the thermostat, on the
circuit board.
OPTION SWITCHES:
There is a square box with 2 small
switches, located to the right side of the
circuit board. Each switch controls a
different setting depending on the
position of the switch. The individual
switches are labeled as 1 and 2, and
there is a corresponding table printed
on the circuit board to show the
possible options for each of the two
switch positions.
TEMPERATURE SCALE (Option Switch #1):
This determines how the thermostat displays all temperatures on the
screen. Switch position OFF is F°, and ON is C°.
TIME FORMAT (Option Switch #2):
This determines how the thermostat displays the clock and all other
times on the screen. Switch position OFF is 12 HR, and ON is 24 HR.
HARDWARE RESET:
The hardware reset is a push button that is located near the center of the
circuit board. This reset button is used by the thermostat to read the
position of the option switches. When either of the two option settings
above are changed, the hardware reset button must be pushed for the
change to be recognized. This can also be used if the thermostat is
exhibiting any erratic behavior. User temperature programs are not
erased when a hardware reset is performed, however you will have to set
the clock and day of the week.
SOFTWARE RESET:
The Software Reset is a small recessed push button that is located to the
right of the NEXT and HOLD buttons. This button can be pushed with a
pencil or the end of a paper clip. The software reset clears all of the
user temperature programs, and all other software preferences to their
default values. You should write down your heating program times and
temperatures prior to using the Software Reset.
PUSH BUTTONS:
There are four primary push buttons on the front
of the thermostat: The UP and DOWN arrow keys,
the NEXT button, and the HOLD button.
ROTARY DIAL:
The LUX Speed Dial
®
provides an easy way to
quickly navigate between the different
programming areas. This rotary dial has four
individual positions.
HEAT / OFF SWITCH:
This switch is located on the right side of the
power unit (back half of thermostat) as shown to
the right. In the winter, set the power switch to
HEAT to control your heating system. In the
spring, summer, and fall, set the switch to OFF if
you would like to prevent your heating system
from turning on.
SET DAY/TIME:
Rotate the dial to the SET DAY/TIME position. The day of the week will
start flashing on the display. With the day flashing, press the UP button,
once for each day, to advance to the desired day of the week. Press the
NEXT button; this should cause the time to start flashing and the day to
remain on steady. Using either the UP or DOWN buttons, adjust the
clock to the desired time. The clock digits will increment rapidly if either
the UP or DOWN buttons are held in the pressed position.
TEMPERATURE OVERRIDE:
A Temperature Override occurs in Run mode, anytime the user adjusts
the set temperature to a value other than what the stored program set
temperature is for that day and time. When the thermostat is in an
Override, the word “OVERRIDE” will appear in the bottom of the display
screen. The thermostat will maintain thermal control using this new set
temperature, until the start of the next program period time is reached.
At that time, the set temperature will return to the value stored in
memory for that new program period. To enter an Override, 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 desired set temperature value.
An Override may be cancelled by rotating the dial or by initiating a HOLD.
TEMPERATURE HOLD:
A Temperature Hold is similar to an override, but is used for maintaining
a constant set temperature under manual control, for a longer time
duration. A Hold is the simplest means to set and maintain a fixed
temperature. It allows you to set and maintain a fixed temperature
indefinitely, without concern for programming.
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
flashing set temperature. 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, or
rotate the dial away from RUN.
SWING SETTING:
A thermostat works by turning your heating 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. A single number will appear on the
screen. 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.
MINIMUM RUN TIME DELAY:
This is determined by the thermostat, and controls the minimum length
of time that the thermostat must remain with the Heat either On or Off,
before it will automatically switch to the alternate On or Off state. This
feature prevents rapid undesired cycling of the heating equipment. The
time amount for this delay is fixed at 5 minutes between on or off load
changes.
For the two program types that are described below, this thermostat
provides four independent periods per day for Heat mode, they are:
MORN, DAY, EVE, and NITE. Each period ends at the start time of the
following period. When you install batteries for the first time, or perform
a Software Reset, a default temperature program (shown below) is
inserted into all four of the program periods. You can use this default
program, or alter any portion of it 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.
SET WEEKDAY PROGRAM:
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.
SET WEEKEND PROGRAM:
Turn the dial to WEEKEND PROGRAM. You will be programming both
Saturday and Sunday at the same time. You will begin with the start
time of the MORN period, and use the same procedures that were
performed while setting the Weekday Program periods, using the NEXT
button to advance through the values. Return the dial to the RUN
position when you are finished.
The batteries should be replaced AT LEAST once per year, or sooner if
the LOW BATT battery symbol appears in the lower left portion of the
display screen as shown. To replace the batteries in the thermostat,
open the front door of the unit. The battery
compartment is located just below the rotary dial
and push buttons. Pull the battery compartment
out, starting with the top edge. Remove the used
batteries from the battery tray and discard
appropriately.
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, re-install the
battery compartment by first seating the bottom into its alignment pins,
and pivoting the top in towards the thermostat to snap the latch back
into place.
