• 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.

• A 4-minute minimum on/off time in COOL prevents your air conditioning
system from being damaged.

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

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.

Instructions

Thermostat
Cover

•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.

INSTALLATION

Please read all instructions carefully before beginning installation.

CAUTION

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.

CAUTION

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.

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

CAUTION

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.

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.

WIRING DIAGRAM NOTES
(APPLIES TO ALL DRAWINGS)

• The DASHED lines are optional
depending upon your system type.

• Verify whether “C”, “X” or “B” wires
are connected to system common.

• If “B” and “O” are both present, it is
likely that “B” is a system common.

• If a “B” wire in your system is a
common, then connecting it to the
“B” terminal may cause damage to
your system.

• If “Y” and “C” are both present, it is
likely that “C” is a system common.

R

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.

Attaching Wires

4.Hold the base against the wall, with the wires
coming through wherever it is convenient for wiring.
Route the wires to below the terminal block. Position
the base for best appearance (to hide any marks
from an old thermostat). An optional wall plate is
included for covering old mounting holes. Attach the
base to the wall with the two screws provided.

CAUTION

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.

NOTE

These diagrams below are provided for new installations or

unreferenced wires.
