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.
● Do not locate in a damp area. This can lead to corrosion that will shorten thermostat life.
● Do not locate where air circulation is poor, such as in a
corner or an alcove; or behind an open door.
● Do Locate the thermostat on an inside wall, about 5 ft.
(1.5m) above the floor, and in a room that is used often.
● 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.
● 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.
● Do not install the unit until all construction work and
painting has been completed.
3.3. REMOVAL OF OLD UNIT
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 they may not
comply with any standard.
● Switch electricity to the furnace and air conditioner
OFF; then proceed with the following steps.
● Remove cover from old thermostat. Most are snap-on
types and simply pull off. Some have locking screws on
the on the side. These must be loosened.
● Note the letters printed near the terminals. Attach
labels (enclosed) to each wire for identification. Label and
remove wires one at a time. Make sure the wires do not
fall back inside the wall.
● Loosen all screws on the old thermostat and remove it
from the wall.
3.4. MOUNTING
CAUTION: Be careful not to drop the unit or disturb electronic
parts.
● Strip insulation 3/8 in. (9.5mm) from wire ends and
clean off any corrosion.
● Fill wall opening with non-combustible insulation to
prevent drafts from affecting the thermostat.
● With each thumb on a release tab at the bottom of the
body, and fingers over the top of the unit. Release the
unit from its base plate by squeezing the tabs into the
body.
● Separate the unit from its base plate by pulling the
body outward from the bottom.
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.
Route the wires through the open areas in the base
plate above the terminals. Hold the base against the wall,
with the wires coming through. Position the base for the
best appearance (to hide any marks from an old thermostat). Attach the base to the wall with the two screws provided.

3.5.2 FREEZE PROTECTION
The PSP722E incorporates a mechanical thermal switch
which may be used to prevent a freeze-up by calling for
heat in the event the unit has accidentally been turned off
or its batteries have not been replaced as recommended.
● This switch is available at the E terminal of the thermostat. In most systems using this feature will require
wiring a jumper between the W1 and E terminals. The
thermostat will call then for the first stage of heat, in furnace mode, or Aux heat in heat pump mode. See EMERGENCY HEAT.
● The nominal temperature set point of this switch is
40°F(5°C).
3.5.3 SPECIAL WIRING NOTES
● In heat pump mode, AUX heat is available at W1.
● In heat pump mode, Emergency Heat is activated from
the E terminal. This terminal also provides freeze protection and it will be active below a nominal temperature of
40°F(5°C).
3.5.4 COMMON WIRING OPTIONS
Though not shown here additional second stages may be
used where applicable. Be sure to enable them properly
in the Installer Setup menu.
W2 is second stage heat
E is emergency heat and freeze protection
Y2 is second stage cool or second stage heat pump
OPTIONAL O or B terminals may be used to power heating dampers or changeover valves in any system configuration.
OPTIONAL C terminal may be connected to a system
common to power the thermostat from the system in any
wiring configuration.
WARNINGS: 1. A B wire is sometimes used as a
common wire. Connecting a common B wire to the B terminal in these systems will likely cause damage to the thermostat and/or HVAC system. Do not connect a wire to the B terminal if you are unsure whether it may be wired to a system
common.
2.If Both Y and C wire are present, then C is common. Tape it
off or connect it to the C terminal to allow the system to
power the thermostat.

All settings, their choices and default values are given in
INSTALLER SETUP MENU WITH FURNACE SYSTEM
TYPE SELECTED: and INSTALLER SETUP MENU WITH
HEAT PUMP SYSTEM TYPE SELECTED AND FUTURE
OUTDOOR SENSOR ENABLED.
3.7.1.1 SYSTEM TYPE
This option determines whether the thermostat is to control a furnace and air conditioning system or heat pump
system.
● In furnace mode the unit will make the proper W terminals live for Heating, and the proper Y terminals live
for cooling.
● In Heat Pump mode the unit makes the proper Y terminals live for the first and second stages of a heat pump
unit during heating or cooling. In this mode an additional
stage of Aux Heat may also be activated through the W1
terminal.
3.7.1.5 MINIMUM RUN TIME
Minimum Run Time provides compressor protection and
prevents short cycling. Compressor stages are held off
for a minimum of this time. During program run this is
also the minimum on time.
3.7.1.6 HEAT PUMP LOCKOUT
This menu item is available only in Heat Pump Mode with
an operational outdoor temperature sensor. Enabling this
option allows the thermostat to disable a heat pump and
request AUX Heat below the Heat Pump Lockout
Temperature.
3.7.1.7 HEAT PUMP LOCKOUT TEMPERATURE
This menu item is available only in Heat Pump Mode with
an operational outdoor temperature sensor. With it you
may set the outdoor temperature at which the thermostat
will cease to call for heat pump sourced heat, and use the
alternate AUX Heat source.
3.7.1.8 DEADBAND
When using auto-changeover, deadband provides a disallowed temperature range between the maximum heat
temperature set point and minimum cool temperature set
point. Deadband may be set from 3 to 5 degrees. With
auto-changeover active and the Deadband set to 3°F and
heat set to 70°F the minimum allowed cool temperature
set point will be 73°F. If the cool temperature set point is
lowered, then the heat temperature set point will be lowered by the same amount maintaining the 3°F Deadband.
3.7.1.9 SWING 1
Swing 1 sets the temperature variation the system allows
above the temperature set point before switching the first
stage heat source off, or below the temperature set point
before switching the first stage heat source on. In Cool,
Swing 1 sets the temperature variation the system allows
above the temperature set point before switching first
stage of cooling on, or below the temperature set point
before switching the first stage of cooling off.
9
3.7.1.10 SWING 2
This value is similar to the Swing 1, but it controls the
temperature variation the system allows above and below
Swing 1’s lower limit before calling for a second stage.
Once a second stage is activated, it will remain on until
the temperature set point has been reached. If a third
stage of heat is present in heat pump mode, Swing 2 is
used to control it from the stage 2 lower limit.
3.7.1.11 HEAT FAN CONTROL
Fossil fuel furnaces normally control the system fan while
the furnace is operating. Electric systems normally
require the thermostat to activate the fan. This setting
instructs the thermostat how to handle fan control during
heating. Electric heat and heat pumps generally require
the thermostat to activate the fan and therefore use the
electric setting.
3.7.1.12 HEAT FAN ON DELAY
This setting allows the installer to program the length of
time between heating activation and fan activation (delay
on make).
3.7.1.13 HEAT FAN OFF DELAY
This setting allows the installer to program the length of
time between heating deactivation and fan deactivation
(delay on break).
3.7.1.14 COOL FAN ON DELAY
This setting allows the installer to program the length of
time between cooling activation and fan activation (delay
on make).
3.7.1.15 COOL FAN OFF DELAY
This setting allows the installer to program the length of
time between cooling deactivation and fan deactivation
(delay on break).
3.7.1.16 FUTURE OUTDOOR SENSOR
This setting enables and disables an outdoor sensor if it
is present. The setting will be held NA if a sensor is not
present, and will be reset to NA If the sensor is disconnected for any reason, including removal of the thermostat from its base-plate, the thermostat will automatically
disable the sensor changing the setting in this menu
from ON to NA. With an outdoor sensor present and
enabled, the outdoor temperature will be displayed alternately with time. The word OUT will be visible to the right
of the temperature while the outside temperature is displayed.
3.7.1.17 INTERNAL TEMPERATURE SENSOR
This setting enables and disables the thermostats internal
temperature sensor. It may only be disabled if there are
indoor remote sensors present and enabled.
3.7.1.18 FUTURE INDOOR REMOTE SENSOR 1, 2, 3
Used to enable and disable the respective remote sensors
in a system. When more than one indoor sensor is used,
the values of their measurements are averaged for use in
temperature control.

3.7.4 COMPLETING YOUR INSTALLATION
● Turn the power back on to your heating and/or air conditioning system.
● Verify that the system and its fan are operating properly. When set to a high temperature, the heating system
should provide warm air after a short time. Likewise a
cooling system should provide cool air after a short time.
Usually sound from the furnace and air conditioning units
can be heard while they are running. The rush of moving
air should be heard within a short time after either has
been started.
NOTE: If you have an electric system and the blower does not
operate after installation, verify that the electric/gas option in
installer set up is set to Electric.
● Installation is now complete.

period must be lower than the setback period.
● The estimated Smart recovery time must be longer
than 15 minutes for an Smart recovery to be initiated.
● Maximum Smart recovery time is one hour.
● AUX heat will not be activated during the first half hour
of a Smart recovery. Then it will only be activated if necessary to achieve the programmed temperature by the
beginning of the next period.
● The Smart recovery temperature set point must be
achievable. If a desired smart recovery is repeatedly
ignored by your thermostat that is an indicator that you
should modify your program so that the recovery can be
achieved within the 1 hour limit.
● A Smart recovery may not be initiated for 48 hours
after the units programs have been changed. This allows
the unit to gather the data necessary to predict a Smart
recovery time.
4.2.10 FILTER LIMIT
Your thermostat will warn you that your HVAC systems
air filter should be changed after the systems fan has run
the number of hours that this setting has been pro-
grammed for. A general rule of thumb is to assume that
the fan will run at 1/3 duty cycle. A 90 day filter will then
be good for 90*24/3=720 hours. This is the default value.
Setting the filter counter limit to 0000 will disable the
change filter indicator. Valid entries are from 0 to
2000hrs.

4.3.1 EMERGENCY HEAT
● To use an emergency heat system, press the MODE
button repeatedly until the EMER HT is shown along the
top of the display. The unit is in emergency heat mode
ready to control your emergency heating system. In heat
pump systems, the emergency heat terminal is often
wired to W1 the AUX heat terminal.
● Press temperature UP or DOWN keys until your
desired temperature is displayed in the HEAT SET area of
the display.
● Freeze protection is also provided at this terminal. See
FREEZE PROTECTION.
4.3.2 FAN MODES
Your thermostat provides three fan modes. They are
AUTO, CLEAN, and ON. The fan may be controlled by
your units program, or the program may be overridden
by pressing the FAN button and selecting another mode.
Appropriate indicators are visible along the top of the
units display when active.
4.3.2.1 FAN AUTO
FAN AUTO denotes that the fan will run only to fulfill your
heating and cooling requirements.
4.3.2.2 CLEAN
This enables the CLEAN CYCLE® feature. The FAN icon
alone in the display denotes that the fan is maintaining
the programmed minimum run time; it will also run additional time as required to maintain temperature control.
The algorithm used avoids additional fan time when the
minimum run time has been met over the last hour
through temperature control. Minimum fan run times are
met by running one third the hourly requirement at twenty minute intervals.
4.3.2.3 FAN ON
FAN ON denotes that your system fan will run continuously.

nonvolatile memory. Take care not to unintentionally
press this button when the thermostat has been
removed from the wall plate!
4.4. PROGRAMMING
You can change the preset time/and temperatures to suit
your schedule for each day of the week. Each day has
four consecutive periods. They are Morning, Day,
Evening, and Night. Separate set points are provided for
Heat and Cool.
Fan programming is similar to temperature programming. It has four consecutive periods, which are independent of the four temperature periods. The default setting for your systems fan requires it to run only as
required by your environmental system. It may be programmed to maintain a minimum run time on an hourly
basis, or run continuously.
4.4.1 WEEKDAY TEMPERATURE PROGRAMMING
● Rotate the dial to Set Weekday Programs. The heat
and cool set points will be displayed on the left side of
the display. The start time for the displayed day will flash
to show that this is the setting currently ready for edit.

changed in the Installer Setup menu. If you move the
heat set point temperature to close to the cool set point
temperature the cool set point temperature will move
away from the heat set point temperature to maintain the
dead band. Conversely the heat set point temperature will
move if you adjust the cool set point temperature to
close. There are programmable limits for both heat and
cool, which you will not be able to exceed. These values
are accessible from the User Setup Menu.
● When you have changed the Cool set point to your
desired temperature, press NEXT to advance to the next
period. Its start time will be flashing indicating that it is
under edit.
