INSTALLATION
PLEASE READ ALL INSTRUCTIONS CAREFULLY BEFORE BEGINNING
INSTALLATION.
C A U T I O N :
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.
TOOLS REQUIRED:
• #1 Phillips screwdriver (small - medium)
• Drill with 3/16-in. (4.8mm) drill bit
• Wire stripper/cutter
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.
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 of 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. Remove and label
one wire at a time, and do not allow the 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.
Be careful not to drop the body or disturb any
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.

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.
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.
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).
WIRING INFORMATION
** Complete heating or cooling system wiring can be found in the WIRE
IDENTIFICATION AND WIRING SCHEMATICS section of this instruction
sheet. The schematics show system components for brand new instal-
lations or for un-referenced wires.
SETUP OPTIONS
If batteries are presently installed, remove them from the thermostat before
proceeding with changing any of the options listed below.
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

JUMPER SETTINGS:
Switch
There are three (3) headers (or jumpers) located inside the thermostat at

OFF
the rear of the circuit board. These settings can be changed from their
COOL
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 option jumper settings will not be recognized
unless the thermostat has been without battery power for at least 2
minutes, and then power is restored again. 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 - FAHRENHEIT OR CELSIUS DISPLAY FORMAT:
This setting controls whether the temperature is shown in
degrees °F or °C on the LCD display screen.
JP2 - 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.
NOTE: If you have an Electric Heat system and the blower does
not operate after installation, locate the "Gas/Electric" option
jumper and ensure that it is in the "Electric" position.
JP3 - [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.
COMPLETING THE INSTALLATION
Once all optional jumper settings have been performed as described in the
previous section, please ensure that the thermostat has been without
battery power for at least 2 minutes. Now install new batteries into the
thermostat. When installing batteries, use two new Energizer
DURACELL ®
installed in the proper direction as per the markings shown in the battery
tray.
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.
NOTE: Before use, remove the plastic film (if present) that is
protecting the LCD display screen.
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.
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 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).
NOTE: The FAN switch only works if your system provides a wire
for the thermostat's "G" terminal.
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.
OPERATING INSTRUCTIONS
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 PSD022B 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 (PSD011Ba ONLY):
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
F
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
JP1 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
C
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
ELECT
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
GAS
temperature modes.
