instructions can be found below.
Part Number 15117
Caution: Electrical Hazard
Failure to disconnect the power before beginning
to install this product can cause electrical shock or
equipment damage.
Mercury Notice:
All of our products are mercury free. However, if the
product you are replacing contains mercury, dispose of it
properly. Your local waste management authority can give
you instructions on recycling and proper disposal.
A trained, experienced technician must install this
product. Carefully read these instructions. You could
damage this product or cause a hazardous condition if
you fail to follow these instructions.
W
For vertical mount put one screw top and one screw bottom.
For horizontal mount put one screw left and one screw right.
The thermostat can be mounted directly to the wall or it can
be mounted to a wall box. Use the vertical mounting screw
location to attach to a wall box.

Installation tips
Wall locations
The thermostat should be installed approximately 4 to 5 feet above the
oor. Select an area with average temperature and good air circulation.
NOTE: Pick an installation location that is easy for the
user to access. The temperature of the location should be
representative of the building
Do not install thermostat in locations:
• Close to hot or cold air ducts
• That are in direct sunlight
• With an outside wall behind the thermostat
• In areas that do not require conditioning
• Where there are dead spots or drafts (in corners or
behind doors
• Where there might be concealed chimneys or pipes

Thermostat wiring
1. If you are replacing a thermostat, make note of the
terminal connections on the thermostat that is being
replaced. In some cases the wiring connections will
not be color coded. For example, the green wire
may not be connected to the G terminal.
2. Loosen the terminal block screws. Insert wires then
retighten terminal block screws.

Terminal designations
W - Heat relay
Y - Compressor relay
G - Fan relay
O - Heat pump changeover valve energized in cooling
RC - Transformer power for cooling
RH - Transformer power for heating
B - Heat pump changeover valve energized in heating
C - Common wire from secondary side of cooling
system transformer
Wiring tips:
RH & RC terminals
For single transformer systems, leave the jumper wire in
place between RH and RC. Remove jumper wire for two
transformer systems.
Heat pump systems
If wiring to a heat pump, use a small piece of wire (not
supplied) to connect terminals W and Y.
C terminal
The C (common wire) terminal does not have to be
connected when the thermostat is powered by batteries.
Wire specifications
Use shielded or non-shielded 18-22 gauge thermostat wire.
Caution: Electrical hazard
Failure to disconnect the power before beginning
to install this product can cause electrical shock or
equipment damage.
Warning:
All components of the control system and the
thermostat installation must conform to Class II circuits
per the NEC Code.

Important:
The low battery indicator is displayed when the AA
battery power is low. If the user fails to replace the
battery within 21 days, the screen will only show the low
battery indicator but maintain all functionality. If the user
fails to replace the batteries after an additional 21 days
(days 22-42 since rst “low battery” display) the set points
will change to 55°F (Heating) and 85°F (Cooling). If the
user adjusts these setpoints away from these it will hold
for 4 hours then return to either 55°F or 85°F. After day
42 the batteries must be replaced immediately to avoid
freezing or overheating because the thermostat will shut
the unit off until the battery is changed.

Thermostat settings Gas or electric setup
Gas: For systems that control the fan during a call for
heat, put the fan operation switch to the GAS position.
Electric: The fan operation switch should be put in the
ELEC position. This setting allows the thermostat to
operate the fan when the fan relay is connected to the G
terminal.
Fahrenheit/Celsius display
Select For Cwith the jumper pin on the back of the
thermostat. For Fahrenheit install the jumper pin on the
top two pins. For Celsius install the jumper pin on the
bottom two pins.
12 or 24 hour time
12 or 24 hour (military time) can be selected with the
jumper pin. For 12 hour time install the jumper pin on the
top two pins. For 24 hour (military time) install the jumper
pin on the bottom two pins.
Important:
The RESET button must be pressed after changing
any switch or jumper pin setting. Batteries must be
installed for this operation.

Attaching the thermostat to the subbase
Align the 4 tabs on the subbase with corresponding slots
on the back of the thermostat, then push gently until the
thermostat snaps in place.
Battery installation
Battery installation is recommended even if thermostat
is hardwired (C terminal connected). When thermostat
is hardwired and batteries are installed, the thermostat
will activate a compressor delay of 5 minutes when the
thermostat detects a power outage from the hardwired
power supply (batteries included).
Important:
High quality alkaline batteries are recommended.
Rechargeable batteries or low quality batteries do not
guarantee a 1-year life span.
Insert 2 AA Alkaline
batteries (included). High
quality alkaline batteries
are recommended.
Simple operating
instructions are found
on the back of the
battery door.

Programming the thermostat
Adjusting the room temperature
The current room temperature is displayed in large text in
the center of the thermostat under the “room temperature”
heading. The set point or desired room temperature is in
the upper right corner of the display under “set at”. To
raise or lower the desired “set at” temperature use the red
and blue +and –buttons on the top right of the
thermostat.
Swing setting tip
Temperature swing, sometimes called differential or cycle
rate, can be customized for this individual application. For
most applications choose a swing setting that is as long
as possible without making the occupants uncomfortable.
This thermostat has a technician setup menu for easy
installer conguration. To setup the thermostat for your
particular application:
1. Press MENU button.
2. Press and hold TECH SET button for 3 seconds. This
3 second delay is designed so that homeowners do
not accidentally access the installer settings.
3. Congure the installer options as desired using the
table below.
Use the +or –keys to change settings and the
NEXT STEP or PREV STEP key to move from one
option to another. Note: Only press DONE key when
you want to exit the Technician Setup options.

Description
This feature will
ash "FILT" in the
display after the
elapsed run time to
remind the user to
change the lter. A
setting of "off" will
disable this feature
This feature
allows the installer
to change the
calibration of the
room temperature
display. For
example, if the
thermostat reads
70° and you would
like it to read 72°
then select +2.
This feature allows
the installer to
select the minimum
run time for the
compressor. For
example: A setting
of 4 will force the
compressor to
run for at least 4
minutes every time
the compressor
turns on, regardless
of the room
temperature
The compressor
short cycle delay
protects the
compressor from
"short cycling". This
feature will not allow
the compressor to
be turned on for 5
minutes after it was
last turned off.
The swing setting,
often called "cycle
rate", "differential"
or "anticipation"
is adjustable. A
smaller swing
setting will cause
more frequent
cycles and a larger
swing setting will
cause fewer cycles.

You can adjust
the lter change
reminder from "off"
to 2000 hours of
runtime in 50 hour
increments.
Tap the second
button from the
top left side of
the thermostat to
display the current
lter.
You can adjust the
room temperature
display to read -4°F
to +4°F above or
below the factory
calibrated reading.
You can select
the minimum
compressor run
time from "off",
"3", "4", or "5"
minutes. If 3, 4,
or 5 is selected,
the compressor
will run for at least
the selected time
before turning off.
Selecting "on"
will not allow the
compressor to
be turned on for
5 minutes after
the last time the
compressor was
on. Select "off" to
remove this delay.
The cooling swing
setting is adjustable
from ±0.2°F to
±2°F. For example:
A swing setting
of 0.5°F will turn
the cooling on at
approximately 0.5°F
above the setpoint
and turn the cooling
off at approximately
0.5°F Below the
setpoint.
The heating swing
setting is adjustable
from ±0.2°F to
±2°F. For example:
A swing setting
of 0.5°F will turn
the heating on at
approximately 0.5°F
below the setpoint
and turn the heating
off at approximately
0.5°F above the
setpoint.
