Thank you for your confidence in our product. You should become fully
acquainted with this thermostat before installing it for usage. Follow the
installation procedures carefully, and one step at a time. This will save you
time and minimize the chance of damaging either the thermostat or the
systems that it controls. These instructions may contain information
beyond that required for your particular installation. Please save these
instructions for future reference.
• The single-stage PSD011Wa thermostat can be used with most 24 volt, 1
stage heat and/or 1 stage cool: gas, oil, or electric heating and air
conditioning systems, or single-stage heat pumps.
• The multi-stage PSD022Wa thermostat can be used with most 24 volt, 2
stage heat and/or 2 stage cool: gas, oil, or electric heating and air
conditioning systems, or single-stage heat pumps.
• These thermostats cannot be used to control 3-wire zone valves, gas
Millivolt heating systems, multi-stage heat pumps, or 120/240 volt (line
voltage) heating or cooling systems. Ask your dealer for other LUXPRO
thermostats to control those systems.
PLEASE READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING
INSTALLATION.
TOOLS REQUIRED:
• #1 Phillips screwdriver (small - 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 instal-
lations, 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, and 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. Do not allow wires to touch each other or any
parts of the thermostat.
5. Loosen all screws on the old thermostat and/or base, and remove it from
the wall.
MOUNTING THE NEW THERMOSTAT:
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 while in use.
3. Pull your new thermostat apart by applying pressure to the thumb tab on
the bottom edge of the unit. While pressure is being applied to this
release latch, pull the two halves of the thermostat apart near the bottom
edge.
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 as shown here.
6. Securely tighten all electrical terminal screws
(even unused ones).
** Complete heating or cooling system wiring can be found in the WIRE
IDENTIFICATION AND WIRING SCHEMATICS section of this instruction
sheet. The schematics shown provide component information for brand
new installations or for un-referenced wires.
A table similar to this one shown below is printed on the thermostat's
circuit board. There may be minor differences present in some of the
wording of your specific model, but the function of each option will be the
same.
JUMPER SETTINGS:
There are four (4) 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 the adjacent pair of metal pins. A change to
ANY of the jumper settings will not be recognized until power to the
thermostat is removed for at least 2 minutes, and then power is restored
again. This can simply be accomplished by removing the thermostat from
the wired back plate. Each of these jumpers changes a different setup
option. The choices for these options are listed in a table printed on the
circuit board, and are also printed adjacent to each individual setting
jumper.
JP1 - FURNACE / HEAT PUMP SYSTEM TYPE:
This setting tells the thermostat about the type of heating
and cooling equipment that it is controlling, so that the
system is operated properly. There are two operating modes
based on your system type, “Furnace (FURN)” or “Heat
Pump (HP)”. If you have a Furnace, ensure this is set to
“Fn”. If you have a Heat Pump, ensure this is set to
“HP”.
JP2 - FAHRENHEIT OR CELSIUS DISPLAY FORMAT:
This setting controls whether the temperature is shown
in degrees °F or °C on the LCD display screen.
JP3 - GAS / ELECTRIC FAN OPERATION:
This setting defines the fan operation while in Heat mode,
and when the fan is in Auto.
GAS: Use this setting if you have a Gas or Oil heating
system. In the GAS setting, the heating system itself
controls the operation of the blower fan (if equipped).
ELECTRIC: Use this setting if you have a Heat Pump or
Electric heating system. In the ELEC setting, the heating
system requires the thermostat to control the operation
of the blower fan.
JP4 - [B] OR [O] TERMINAL USAGE OPTION:
This setting determines how the thermostat will use the
shared B/O terminal connection on the back plate. Choose
the UP (B) position to have the B/O terminal powered
while in heat mode, and un-powered while in cool and off
modes. Choose the DOWN (O) position to have the B/O
terminal powered while in cool mode, and un-powered
while in heat and off modes.
Once any optional jumper settings have been performed as described in the
previous section, ensure that at least 2 minutes have passed since the
thermostat has been last powered. Install your new thermostat onto its
base. To do this, start with the bottom tilted out towards you at first, and
line up the two holes in the top of the thermostat with the two hooks on
the top of the back plate. Slowly pivot the bottom of the thermostat
towards the back plate and push firmly on the bottom half of the
thermostat until it is securely latched to the back plate. If the two
thermostat halves do not latch easily, remove and try again. Do not
attempt to force them together.
Turn the electrical power back ON to both your heating and/or air
conditioning systems. Verify that both systems (and the blower fan if used)
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/or air
conditioning units can be heard while either is running. If your system
uses a blower fan, the rush of moving air should be heard within a short
time after either has been started. Your installation is now complete.
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.
FAN MODE SWITCH:
The FAN switch has two positions: AUTO and ON.
• 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 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).
PUSH BUTTONS:
There are two push buttons to the right of the unit's display screen. These
are used to adjust the set point temperature.
TEMPERATURE ADJUSTMENT:
While in HEAT or COOL mode, a single press on either the UP or DOWN
button causes the word “SET” to appear on the screen. Once “SET” is
present, the set temperature value starts flashing and the set point
temperature can be altered by pressing either the UP or DOWN button once
per degree of change, or by holding either button for at least two seconds
to automatically increment the set point quickly in the associated direction.
Based upon the relationship of the set temperature to the displayed
ambient room temperature, the thermostat will engage either the W1
terminal in heat mode or the Y1 terminal in cool mode, if a temperature
demand is present.
(For the PSD022Wa model only):
If there is a large thermal demand present which is greater than the first
stage of heating (W1) or cooling (Y1) can accommodate for, then a second
stage of heating (W2) or cooling (Y2) will be activated. When the second
stage of either heating or cooling becomes active, the word “AUX” will be
shown on the display screen. There is approximately a 4 minute delay that
is enforced between the activation of the first stage and the second stage
of heating or cooling.
DISPLAY ILLUMINATION:
Pressing either set temperature button will illuminate the display for easier
viewing in dim light conditions. The light will remain on for approximately
12 seconds. While the light is illuminated, pressing any of the three push
buttons will continue the lighting and remain on for approximately 12 more
seconds.
MINIMUM RUN/OFF TIME:
This is determined by the thermostat, and controls the minimum length of
time that the thermostat must remain with Heat or Cool either On or Off,
before it will automatically switch to the alternate On or Off state. This
feature prevents rapid or short cycling, and provides compressor
protection for cooling equipment. The time amount for this delay is fixed at
5 minutes between on or off load changes.
TEMPERATURE LIMIT STOPS:
There are two independent set temperature stops: a Maximum Heat Set
Temperature, and a Minimum Cool Set Temperature. Each of these
temperature stops is user adjustable in one-degree increments. The heat
limit stop prevents the set temperature from being adjusted higher than the
heat limit setting. The cool limit stop prevents the set temperature from
being adjusted lower than the cool limit setting.
To set the heat and cool set temperature limit stops, always start with the
system mode switch in the OFF position. Press and hold the UP key while
sliding the mode switch from either OFF to HEAT (to adjust the maximum
heat set temperature), or from OFF to COOL (to adjust the minimum cool
set temperature). “Ht Lim” or “Cl Lim” will be displayed on the LCD screen
while you are setting the heat or cool limits respectively. While in the
adjustment mode for each of the temperature stops, use the UP and DOWN
buttons to adjust the limit value, just as you would for adjusting the set
temperature under normal operation. NOTE: If no buttons are pressed for
4 seconds, the thermostat will accept the limit value that was on the
screen, and return to normal operating mode, for the current mode switch
position. Once, complete, you should return to the adjustment mode again
for both heat and cool to confirm your desired settings for both
temperature modes.

CAUTION:
This thermostat is protected against normal static electric
discharges. However, in extremely dry weather you should touch
a grounded metal object before touching the thermostat to
minimize the risk of causing damage to the unit.
CAUTION:
Be careful not to drop the body or disturb any
of the electronic parts.
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.
NOTE: The FAN switch only works if your system provides a wire
for the thermostat’s "G" terminal.
NOTE: Before use, remove the plastic film (if present) that is
protecting the LCD display screen.
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).
CAUTION:
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.
