• The PSP211 can
be used with
most 24 volt
gas, oil or elec-
tric heating and
air conditioning
systems, single-
stage heat pumps
or gas millivolt heat-
ing 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 PSP211 is
programmable.
There are four
programming periods
per day. Each period can be programmed separately.
•Easy to use Speed Slide.
• You can use the built-in time/temperature programs, or alter them to suit your
schedule. The PSP211 provides separate programming for weekdays and weekends
— 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 PSP211 may maintain
cooler “set back” room temperatures to save energy. It will then change to warmer
“comfort” settings — automatically, at specified times during the day.
• In warm weather, when the system switch is set to COOL, the PSP211 may main-
tain warmer “set back” room temperatures to save energy. It will then change to cool-
er “comfort” settings — automatically, at specified times during the day.
• A liquid crystal display shows time, day of the week, and room and set
temperatures.
• Temperature swing adjustment lets you fine-tune your system for maximum
comfort and economy.
• A 2 or 5-minute minimum off time in COOL prevents your air conditioning system
from being damaged.
• Two “AA” batteries (not included) are used to retain your time and temperature
program.

IMPORTANT!
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.

Please read all instructions carefully
before beginning installation.
TOOLS REQUIRED

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.
OFF
REMOVING THE OLD THERMOSTAT
Switch electricity to the furnace and air conditioner
OFF; then proceed with the following steps.
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 PSP211 ON THE WALL
3. Cup and hold thermostat body and left tab in place with left hand. Separarte tabs
with right hand.
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.
Y
W
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.
CAUTION
Be careful not to drop the body or disturb electronic parts.
Y
W
R
2. Fill wall opening with
non-combustible
insulation to prevent
drafts from affecting
the thermostat.
Y
W
1. Strip insulation 3/8 in.
(9.5mm) from wire ends
and clean off any corrosion.
CAUTION
• 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 condition-
er 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 thermo-
stat 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.
WARNING: Use Energizer® or 
DURACELL® Alkaline Batteries ONLY for 
all Lux thermostats requiring batteries.

ATTACHING WIRES
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 securely tighten all 7 electrical terminal screws.
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.

to display the room temperature alternately with the time. To correct the display, see
“Setting the TIME and DAY,”after you set the programs.
NOTE
If you have an electric system and the blower does not operate after installation, find the
electric/gas heat jumper on the back of the body. Move the jumper to the ELEC position.
REPLACE BATTERIES WHEN

SETTING THE TIME AND DAY
To change
current day.
Move the Speed Slide to SET DAY/TIME position. You should see the display pictured
above with a day of the week flashing. When you are finished setting the day and time,
rotate the dial to RUN to return to normal operation or to another position to continue
programming.
CAUTION
The PSP211 is protected against normal static electric discharges.
However, in extremely dry weather you should touch another metal
object before the PSP211 to avoid potential loss of programs.
To change the
current time.
To set current time. The (e.g.
“12:00”) will be flashing.
The PSP211 alternately displays
the current time and the room
temperature. It also displays the day of
the week and the currently active pro-
gram period that is controlling the temperature: MORN, DAY, EVE, or NITE.
The set point temperature will appear in the right side of the display. In the winter, set the
system switch to HEAT to control your heating system. In the summer, set the switch to
COOL to control your air conditioner. In spring and fall or when windows are open, you can
set the system switch OFF.
Setting the FAN switch to AUTO
automatically runs your system’s fan
during heating and cooling. Setting
the FAN switch to ON runs your sys-
tem’s fan continuously even without heating or cooling.
NOTE
The FAN switch works only if your system
provides a wire for the PSP211’s “G” terminal.
PROGRAMMING THE PSP211
You can change any preset times and/or temperatures to suit your schedules for the
weekday and weekend programs. Each period (Morning, Day,
Evening, and Night) is programmed for HEAT and for COOL.

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. Setting “1”is
approximately 1/4°F. Each increase of 1 value increases the swing by approximately 1/4°F.
A larger swing number decreases the number of cycles, and may save energy in some
cases.
