Push in the RESET key. This sets the

built-in heating and cooling programs.
To review the built-in programs,press
NEXT or PREVIOUS repeatedly; when
you are done, press RETURN.

You can use the built-in programs as

shown, or change them as you wish.
Each day is divided into four periods.
Each period has its own starting time
and temperature.

TEMPERATURE SWING

A thermostat works by turning your heating or cooling system on and off whenever the room

temperature varies a certain number of degrees from the set-point temperature. This variation is the
“swing.” Your system should cycle on about 3 to 6 times per hour. A smaller swing number increases
the number of cycles, so room temperature is more constant. A larger swing number decreases the
number of cycles, to save energy in most cases.

•

The Unit can be

used with most

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 120
volt heating systems or
multistage heat pumps. Ask
your dealer for other LUX
thermostats to control
those systems.

•

The Unit is programmable.
There are four programming
periods per day. Each
period can be programmed
separately.

•

You can use the built-in

time/temperature

programs, or alter them

to suit your schedule. The
Unit provides separate
programming for every day
of the week- for both heating and cooling. You can override the programmed temperatures for as
little as one programming period or for an entire vacation.

•

In cool weather, when the system switch is set to HEAT, the Unit will maintain cooler “set back”
room temperatures to save energy. It will then change to warmer “comfort” settings — all
automatically, at specified times during the day.

•

In warm weather, when the system switch is set to COOL, the Unit will maintain warmer “set
back” room temperatures to save energy. It will then change to cooler “comfort” settings - all
automatically, at specified times during the day.

•

A large liquid crystal display shows time, day of the week, and room and set temperatures.
It will remind you when the filter should be changed in your blower and track your system’s energy
usage.

•

Temperature swing adjustment lets you fine-tune your system for maximum comfort and
economy.

•

5/2 Minute Selectable Minimum Run/Off Time for Short Cycle/Compressor Protection.

•

Two Energizer® or DURACELL® “AA” alkaline batteries (not included) are used to retain your
time and temperature programs.

INSTALLATION

I M P O R T A N T !

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 before installing your new thermostat. Then follow the
installation procedures, one step at a time. This will save you time and
minimize the chance of damaging the thermostat and the systems it controls.
These instructions may contain information beyond that required for your
particular installation. Please save for future reference.

READ

INSTALLATION

INSTRUCTIONS

FIRST

Please read all instructions carefully

before beginning installation.

TOOLS REQUIRED

#1 Phillips screwdriver (small)
Drill with 3/16-in. (4.8mm) bit

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, 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: in direct

sunlight; near a lamp, radio, television, radiator, register, or fireplace; near hot water pipes in a wall;
near a stove on the other side of a wall.

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 in a damp area. This can lead to corrosion that will shorten thermostat life.
5. Do not locate where air circulation is poor, such as: in a corner or an alcove; or behind an open

door.

6. Do not install the unit until all construction work and painting has been completed.
7. This thermostat does not require leveling.

C A U T I O N

To avoid electrical shock and

to prevent damage to the

furnace, air conditioner, and

thermostat, disconnect the power

supply before beginning work. This

can be done at the fuse box, at the

circuit breaker, or at the appliance.

OFF

REMOVING THE OLD THERMOSTAT

Switch electricity to the furnace and air conditioner OFF; then
proceed with the following steps.
1. Remove cover from old thermostat. Most are snap-on types and

simply pull off. Some have locking screws on the side. These
must be loosened.

2. Note the letters printed near the terminals. Attach labels

(enclosed) to each wire for identification. Remove and label wires
one at a time. Make sure the wires do not fall back inside the
wall.

3. Loosen all screws on the old thermostat and remove it from the

wall.

MOUNTING THE UNIT ON THE WALL

1. Strip insulation 3/8 in. (9.5mm) from wire ends and clean off any corrosion.
2. Fill wall opening with non-combustible insulation to prevent

drafts from affecting the thermostat.

3. Press up on the button on bottom of thermostat and swing the

body away from the base and up to remove the body from the base.

C A U T I O N

Read instructions carefully

before removing any

wiring from existing

thermostat. Wires must be

labeled before they are

removed. When removing

wires from their terminals,

ignore the color of the

wires since these may not

comply with the standard.

Do not allow wires to touch each other or parts on thermostat. Wires must be

trapped between black spacer and brass terminal. Also, be sure to tighten securely

all 7 electrical terminal screws.

N O T E

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.

FILTER USAGE MONITOR

The FILTER Monitor counts the hours since the filter in your blower was last changed. After 250

hours of use, FILTER will appear in the display. After you change the filter, set the thermostat’s FILTER
Monitor back to zero as follows.

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

• Turn off electricity to the appliance before installing or servicing thermostat or any

part of the system. Do not turn electricity back on until work is completed.

• Do not short (jumper) across electric terminals at control on furnace or air conditioner

to test the system. This will damage the thermostat and void your warranty.

• All wiring must conform to local codes and ordinances.

• This thermostat is designed for use with 24 volt and millivolt systems. The thermostat

should be limited to a maximum of 1.0 amps; higher amperage may cause damage

to the thermostat. If you are in doubt, call your utility company.

SMART RECOVERY

Your thermostat has the capability to turn the HEAT and AIR CONDITIONING

ON in your home so that it

reaches your desired comfort temperature at the time you have programmed. For instance, if you have pro-
grammed your thermostat for 70° at 5:00pm, normally the thermostat will begin to heat your home at 5:00pm.
With SMART RECOVERY on, the thermostat will calculate the best time to turn the heat on so that the temper-
ature in your home reaches 70° by 5:00pm. It calculates the amount of time through experience and will get
more accurate as time goes by. To enable SMART RECOVERY, remove J4 on the back of the thermostat. Press
