INSTALLATION AND OPERATING INSTRUCTIONS
1. Switch OFF the electricity to the furnace or heating equipment; then
proceed with the following:
SYSTEM MODE SWITCH:
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.
The MODE switch has two positions: HEAT and OFF. In the winter, set
the mode switch to HEAT to control your heating system. In the
spring and fall, or when the windows are open, you can set the switch
OFF.
3. Take note of the letters printed near the wire terminals. Attach
labels (enclosed) to each wire for identification by terminal letter,
not color.

PUSH BUTTONS:
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.
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 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.
C A U T I O N :
Be careful not to drop the body or disturb
any of the electronic parts.
WARNING: Use Energizer® or DURACELL® Alkaline Batteries Only.

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.
I M P O R T A N T !
Please read all instructions carefully before beginning
installation and save for future reference. Before
removing any wiring from your existing thermostat, the
wires must be labeled with their terminal designations.
Ignore the color of the wires since they may not
comply with any standard.
Based upon the relationship of the set temperature to the displayed
ambient room temperature, the thermostat will engage the W1
terminal in heat mode, if a temperature demand is present.
DISPLAY ILLUMINATION:
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.
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.
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 instal-
lation. Please save these instructions for future reference.
MINIMUM RUN/OFF TIME:
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.
This is determined by the thermostat, and controls the minimum
length of time that the thermostat must remain with Heat either On or
Off, before it will automatically switch to the alternate On or Off state.
This feature prevents rapid or short cycling of the heating equipment.
The time amount for this delay is fixed at 5 minutes between on or off
load changes.
COMPATIBILITY
• The single-stage PSD010Bc thermostat can be used with most 2-wire
24-volt heating systems that do not have a blower fan.
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).
ADJUSTABLE TEMPERATURE STOP:
• The PSD010Bc thermostat can also be used with Millivolt systems.
This model has an Adjustable Temperature Stop. This is a set
temperature limit, and is user adjustable in one-degree increments.
The temperature stop prevents the set temperature from being
adjusted to a value that is higher than the temperature stop setting.

JUMPER SETTINGS:
• Easy To Install
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 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.
INSTALLATION
PLEASE READ ALL INSTRUCTIONS CAREFULLY BEFORE
BEGINNING INSTALLATION.

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.
Once an optional jumper setting has been performed as described
above, 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® or
DURACELL® “AA” size alkaline batteries only. Ensure that the batteries
are installed in the proper direction as per the markings shown in the
battery tray.
•
•
Your thermostat is a precision instrument.
Please handle it with care.
Do not short (jumper) across the electric terminals for the
furnace 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.
COMPLETING THE INSTALLATION
•
•
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.
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, at about 5 ft. (1.5m) above
the floor, and in a room that is used often.
NOTE: Before use, remove the plastic film (if present) that is
protecting the LCD display screen.
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.
Turn the electrical power back ON to your heating system. Verify that
the system is operating properly. When set to a high temperature, the
heating system should provide warm air after a short time in Heat
Mode. Usually, sound from the furnace or heating system can be
heard while it is running. Your installation is now complete.
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.
