FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.
DESCRIPTION
Your new White-Rodgers 5-Day/2-Day Digital Thermostat uses
thetechnologyofasolid-statemicrocomputertoprovideprecise
time/temperature control. This thermostat offers you the flexibil-
ity to design heating and cooling programs that fit your needs.
• LCD continuously displays set point, and alternately dis-
plays time and room temperature
• Temperature override until next program period
• Manual program override (HOLD temperature)
• User may select either 12- or 24-hour clock display
• °F/°C convertibility
Features:
• Battery powered (3 “AA” Energizer® alkaline batteries in-
cluded).
• Temperature range 45° to 90°F
• Standard five terminals for single or two-transformer sys-
tems
• Separate 5-day (weekday) and 2-day (weekend) programming
• Simultaneous heat and cool program storage
• Preprogrammed temperature control
• B and O terminals for single stage heat pumps or damper
operation
• Four separate time/temperature settings per 24-hour period
PRECAUTIONS
Thisthermostatisintendedforusewithalowvoltagesystem;do
not use this thermostat with a line voltage system. If in doubt
about whether your wiring is millivolt, line, or low voltage, have
itinspectedbyaqualifiedheatingandairconditioningcontractor
or licensed electrician.
CAUTION
!
To prevent electrical shock and/or equipment dam-
age, disconnect electric power to system at main fuse
or circuit breaker box until installation is complete.
Do not exceed the specification ratings.
WARNING
!
Allwiringmustconformtolocalandnationalelectricalcodesand
ordinances.
Do not use on circuits exceeding specified voltage.
Higher voltage will damage control and could cause
shock or fire hazard.
This control is a precision instrument, and should be handled
carefully. Roughhandlingordistortingcomponentscouldcause
the control to malfunction.
Do not short out terminals on gas valve or primary
control to test. Short or incorrect wiring will damage
thermostat and could cause personal injury and/or
property damage.

OPERATION
Before you begin programming your thermostat, you should be
familiarwithitsfeaturesandwiththedisplayandthelocationand
operation of the thermostat buttons. Your thermostat consists of
two parts: the thermostat cover and the base. To remove the
cover, gently pull it straight out from the base. To replace the
cover, line up the cover with the base and press gently until the
cover snaps onto the base.

Now you are ready to program your thermostat. This section will
help you plan your thermostat’s program to meet your needs.
For maximum comfort and efficiency, keep the following guide-
lines in mind when planning your program.
• When heating (cooling) your building, program the tem-
peratures to be cooler (warmer) when the building is vacant
or during periods of low activity.
• During early morning hours, the need for cooling is usually
minimal.

Look at the factory preprogrammed times and temperatures
shown below. If this program will suit your needs, simply press the
RUN PRGM button to begin running the factory preset program.
• °F/°C CONVERTIBILITY — Press and hold SET TIME and
HOLD TEMP buttons until the temperature display is in

• 12-HOUR/24-HOUR CLOCK DISPLAY — The clock is set
to display 12-hour time, which means that the clock will
display AM and PM time (12:00 AM is midnight; 12:00 PM is
noon). However, you may want to display a 24-hour clock
(military-style time). The 24-hour clock display will show 1:00
PM as 13:00, 2:00 PM as 14:00, and so on. To change to the
24-hour clock display, press and hold SET TIME and RUN
PRGM buttons at the same time. In the 24-hour clock mode,
AM and PM are not displayed.
If you want to change the preprogrammed times and tempera-
tures, follow these steps.
Determine the time periods and heating and cooling tempera-
tures for your weekday and weekend programs. You must
program four periods for both the weekday and weekend pro-
gram. However, you may use the same heating and cooling
temperatures for consecutive time periods. You can choose
start times, heating temperatures, and cooling temperatures
independently for both weekday and weekend programs (for
example, you may select 5:00 AM and 70° as the weekday 1st
period heating start time and temperature, and also choose
7:00 AM and 76° as the weekday 1st period cooling start time
andtemperature). Usethetableatthebottomofthepagetoplan
• LOW BATTERY INDICATOR — If the 3 “AA” alkaline
batteries are low and should be replaced, the display will be
blank except for the word BATTERY. When the batteries are
low, pressing any button will cause the display to operate for
ten seconds. After ten seconds, the display will be blank
