COMPATIBILITY

C A U T I O N :

The CAG111 is protected against normal static electric discharges.

However, in extremely dry weather you should touch a grounded metal

object before touching the CAG111 to minimize the risk of causing

damage to the unit.

The CAG111 can be used with most single-stage 24 volt gas, oil, or electric
heating and air conditioning systems, single stage heat pumps, or gas Millivolt
heating systems.  It cannot be used with 3 wire zone valves, 120 volt heating
systems, or multi-stage heat pumps.  Ask your dealer for other LUX thermostats
to control those systems.

CLEAN CYCLE™ (PATENT PENDING)

LUX's Clean Cycle

TM

(Patent Pending) allows you to enable a forced air system

to periodically flow air through your system's filter, cleaning the air in your home,
even when heating or cooling is not being utilized.  In CLEAN mode the fan
maintains the pre-programmed minimum run time of fifteen (15) minutes per
hour; it may run additional time as required to maintain temperature control.
The algorithm used avoids additional fan run time when the 15 minute minimum
has been met over the last hour through temperature control.  Minimum fan run
times are met by running one third of the hourly requirement at twenty (20)
minute intervals.  The minimum fan run time is 15 minutes per hour.

INSTALLATION

PLEASE READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING
INSTALLATION.

C A U T I O N :

Turn off electricity to the appliance before installing or

servicing the thermostat or any part of the system.  Do not

turn the electricity back on until the work is completed.

Your thermostat is a precision instrument.  Please handle it with care.

Do not short (jumper) across the electric terminals on either the furnace or

air conditioner to test the system.  This may damage the thermostat and void
your warranty.

All wiring must conform to all applicable local codes and ordinances.

This thermostat should be limited to a maximum of 1.5 amps; higher current

may cause damage to the thermostat.

TOOLS REQUIRED

#1 Phillips screwdriver (medium)

Drill with 3/16-in. (4.8mm) drill bit

Wire stripper/cutter

THERMOSTAT LOCATION

On replacement installations, mount the new thermostat in place of the old

one unless the conditions listed below suggest otherwise.  On new installations,
follow the guidelines listed below.
1. Locate the thermostat on an inside wall, at about 5 ft. (1.5m) above the floor,
and in a room that is used often.
2. Do not install it where there are unusual heating conditions, such as: direct
sunlight, near a lamp, television, radiator, register, fireplace, on a wall opposite a
stove, or that carries hot water pipes.
3. Do not locate in unusual cooling conditions, such as: on a wall separating an
unheated room, or in a draft from a stairwell, door, or window.
4. Do not locate where air circulation is poor, such as: in a corner or alcove, or
behind an open door.
5. Do not locate in a damp area.  This can lead to corrosion that may shorten
thermostat life.
6. Do not install the unit until all construction work and painting has been
completed.

REMOVING THE OLD THERMOSTAT

1.  Switch 

OFF

the electricity to both the furnace

and air conditioner; then proceed with the
following:
2.  Remove cover from old thermostat.  Most are
snap-on types and simply pull off. Some have
screws on the sides, these must be loosened first.
3.  Take note the letters printed near the wire
terminals.  Attach labels (enclosed) to each wire for
identification by terminal letter, not color.
4.  Make sure the wires do not fall back inside the

wall, and remove and label one wire at a time.
5. Loosen all screws on the old thermostat and/or base, and remove it from the
wall.

MOUNTING THE CAG111

1.  Strip insulation leaving 3/8 in.
(9.5mm) of bare wire on the ends
and clean off any corrosion
present.
2.  Fill the wall opening with non-
combustible insulation to prevent
drafts from affecting the
thermostat.

C A U T I O N :

Be careful not to drop the body or disturb any of the electronic parts.

3. Pull your new thermostat apart by opposite pressure on the two thumb tabs
located on the bottom edge of the thermostat to separate the unit

NOTE:

If you are mounting the base to a soft material like plasterboard, or if

you are using the old mounting holes, the screws may not hold.  Drill a 3/16-
in (4.8mm) hole at each screw location, and insert the plastic anchors
provided.  Then mount the base as described below.

4. Hold the base against the wall.  Route the wires through the larger hole
adjacent to the terminal block.  Position the base for best appearance (to hide
any marks from an old thermostat).  Attach the base to the wall with the two
screws provided.

CONNECTING THE WIRES

5.  Clean bare wire ends must be inserted between the black
clamp plate and the brass terminal.
6.  Securely tighten all electrical terminal screws (even
unused ones).

The diagrams below are provided for new installations or for unreferenced wires.

COMPLETING YOUR INSTALLATION

7. See the "SETUP OPTIONS" section to configure the thermostat's options.

NOTE:

Before use, remove the plastic film that is protecting the LCD display

screen.

8. Install two (2) Energizer

®

or DURACELL

®

"AA" size Alkaline Batteries at this

time.  **For instructions on installing the batteries, see the "BATTERIES AND
MAINTENANCE" section.
9. Install your CAG111 thermostat onto its base.  To do this, line up the tabs on
all four corners and gently push the unit straight onto the base.  Do not use
unnecessary force if the body does not snap into place easily.  Remove the
body, line it back up and try again.
10.Turn the electrical power back ON to both your heating and/or air
conditioning systems.
11.Verify that both systems (and the blower fan) are operating properly.  When
set to a high temperature, the heating system should provide warm air after a
short time in 

Heat Mode

.  Likewise, a cooling system should provide cool air

after a short time when set to a low temperature in 

Cool Mode

.  Usually, sound

from the furnace and air conditioning units can be heard while either of them is
running.  The rush of moving air should be heard within a short time after either
has been started.
12.Your installation is now complete.

NOTE:

If you have an Electric Heat system and the blower does not operate

after installation, locate the "Gas/Electric" option inside the back of the
thermostat.  Move the jumper to the "Electric" position.

SETUP OPTIONS

NOTE:

This thermostat is able to be installed and used without changing the

items in this SETUP OPTIONS section.  These are optional, and are provided
to meet your personal preferences.

HARDWARE RESET

The Hardware 

RESET

button restarts your thermostat's internal programming

and then returns the unit back to normal operation.  A press of this button is
required to recognize any jumper setting changes performed at the back of the
thermostat on the circuit board.  This reset is a white button located inside on
the back of the thermostat, on the circuit board.  It is labeled 

RESET

.

JUMPER SETTINGS

There are five (5) headers (or jumpers) located inside the thermostat at the

rear of the circuit board.  These settings can be changed from their default
values by removing its corresponding black jumper cap and reinstalling the cap
so that it is positioned on only one (1) of the metal pins, and not both.  A change
to ANY of the jumper settings will not be recognized by the thermostat until a
HARDWARE RESET is performed.  An OPEN jumper means the cap is only on
one (1) metal pin, and a CLOSED jumper
means the cap is on both of the metal pins.
Each of these jumpers changes a different
option, the choices for these options are listed
in a table printed on the circuit board.

A table similar to this one shown here is

printed on the thermostat's circuit board.
There may be minor differences in some of the
wording of your specific model, but the function of each option will be the same.

JP1 - 5 OR 2 MINUTE MINIMUM RUN/OFF TIMES

This setting changes the minimum length of time that the heating or cooling

system must remain either on or off before it will automatically switch to the
alternate on or off state.  The purpose of this feature is to provide air
conditioning compressor protection by preventing brief or undesirable on/off
cycling.

JP2 - FAHRENHEIT OR CELSIUS DISPLAY FORMAT

This setting controls whether the temperature is displayed in degrees °F or

°C on the LCD screen.

JP3 - TEMPERATURE SWING SETTING

This setting changes the size of the temperature control band with respect to

the set point.  The larger the swing setting, the larger the temperature control
range will be.  Conversely, the smaller the swing setting, the smaller (or tighter)
the temperature control range will be.  This setting is called NARROW and
WIDE.

JP4 - GAS / ELECTRIC FAN OPERATION

This setting changes whether the system's blower fan (if applicable) is

controlled by the thermostat in 

HEAT

mode.  Choose 

ELECTRIC

if you have

electric heating, and require the thermostat to control the fan.  Choose 

GAS

if

you have a gas heating system, this will allow the furnace itself to control the
operation of the blower fan.

OPERATING INSTRUCTIONS

SYSTEM MODE SWITCH:

The MODE switch has three positions: 

HEAT

OFF

, and 

COOL

.  In the winter,

set the mode switch to 

HEAT

to control your heating system; in the summer, set

the switch to 

COOL

to control your air conditioning.  In the spring and fall, or

when the windows are open, you can set the switch OFF.  When the switch is in
the 

HEAT

position, the word "HEAT" will be displayed next to the temperature.

When the switch is in the 

COOL

position, the word "COOL" will be displayed

next to the temperature.  Either of these indicators will be flashing if the system
is currently running, or on steady if the system is not currently running.

NOTE:

When the system mode switch is in the OFF position, it is normal for

the system's blower fan ("G" terminal if used) to still become activated
depending upon the position of the FAN mode switch (see below).

FAN MODE SWITCH:

The FAN switch has three positions: 

AUTO

CLEAN

, and 

ON

.  Whenever the fan

is commanded on by the thermostat, the word "FAN" will flash on the LCD
display.

In the 

AUTO

position, the operation of the blower fan is determined only by

the on/off cycling of the heating and cooling systems.

When the FAN switch is in the 

CLEAN

position, this will enable the IAQ

Clean Cycle™ (Patent Pending) feature.  This will assist in improving Indoor Air
Quality by circulating and filtering the air by using the system's blower fan on a
timed basis.  Your heating and cooling systems will still work as they normally
would.  This Clean Cycle™ feature will ensure that the blower fan will run for a
minimum of fifteen (15) minutes per hour every hour, even if there is no demand
for either heating or cooling system activation (this includes when the System
Mode Switch is in the 

OFF

position).  The 15 minute required run time is

accomplished by monitoring the amount of time the heating or cooling system
has already run the fan within the past hour based upon a total of three 20
minute segments.  If the required 15 minutes per hour of run time has already
been met by running either the heating or cooling, there will be no additional fan
run time made by the Clean Cycle™ feature.

When the FAN switch is in the 

ON

position, the system's blower fan will be

commanded ON, and remain ON while the FAN switch is in the ON position (this
also includes when the System Mode Switch is in the OFF position).

NOTE: 

The FAN switch only works if your system provides a wire for the

CAG111's "G" terminal.

PUSH BUTTONS:

There are four push buttons to the right of the unit's display screen.  These

are used to: adjust the set point temperature, modify the values for user
changeable options, select the filter duration, and illuminate the attractive
screen's backlight feature.

TEMPERATURE ADJUSTMENT:

While in 

HEAT

or 

COOL

mode, a single press on either the 

UP

or 

DOWN

button causes the set point to start flashing.  Once flashing, the set point can be
altered by pressing either the 

UP

or 

DOWN

button once per degree of change,

or by holding either button down for at least two seconds to automatically
increment the set point quickly in the associated direction.

AIR FILTER LIFE COUNTER

The air filter monitor feature tracks the total amount of fan run time to

calculate the estimated remaining life of the filter or recommended calendar
days.  The LCD display shows the remaining filter life in an easy to view bar
graph that can be set to display either days remaining, or percent (%) remaining
(refer to the "SETUP OPTIONS" section for instructions on changing options for
this feature).  The default filter life is ninety (90) days.  This duration may be
altered by pushing the 

FILTER

button on the front of the thermostat and using

either the 

UP

or 

DOWN

buttons to cycle through the available choices of: 000,

30, 60, 90, or 120 days.  A selection of 000 will disable the filter counter
completely and remove the bar graph from the display.  When the filter usage
timer has counted all the way down, it will indicate the need for filter
replacement by displaying a flashing red box containing the words "FILTER
CHANGE".  If you are in the DAYS mode (which is default), the LCD will count
down to zero (0) and then back upwards to indicate the amount of days over the
recommended filter replacement time.  If you are in the percent (%) mode, the
LCD will count down to zero (0) and then back upwards to indicate the amount
of percentage over the recommended filter usage amount up to 100 percent
over.  To reset the filter counter after replacing your filter, either press and hold
the 

FILTER

button for at least three (3) seconds, OR press the 

FILTER

button

once and then the 

UP

or 

DOWN

buttons to change to a different filter duration

setting.

DISPLAY ILLUMINATION:

Pressing the 

LIGHT

button will illuminate the display for easier viewing in dim

light conditions.  The light will remain on for approximately 10 seconds.  While
the light is illuminated, pressing any of the four push buttons will continue the
lighting and remain on for approximately 10 more seconds.

USER TEMPERATURE CALIBRATION:

If the ambient temperature displayed on the LCD screen does not exactly

match a nearby thermometer, or perhaps another thermostat in the home, the
user has the ability to adjust or shift the displayed temperature.  The displayed
temperature can be altered by up to 5°F (or 3°C) in either direction.  This
adjustment is performed by first placing the System Mode switch to the 

OFF

position, then by pressing and holding both the 

UP

and 

DOWN

buttons

together for at least two (2) seconds, the lower (red) portion of the screen will
display the word SET, and the default selection of zero (0).  Press either the 

UP

or 

DOWN

buttons for the associated direction of change.  Note: If no buttons

are pressed within four (4) seconds, the thermostat will return back to normal
run mode.
