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 7-Day Digital Thermostat uses the
technology of a solid-state microcomputer to provide precise
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
• Separate program for each day of the week
• Simultaneous heat and cool program storage
• Preprogrammed temperature control
• Standard five terminals for single or two-transformer
systems
• 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 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.

Cooling System
This thermostat has a built-in short-term (5-minute) time delay.
This feature is activated after the compressor shuts down and
the setpoint is changed within the 5-minute period. During this
5-minute period, COOL will flash on the display indicating that
the thermostat has locked out the compressor to allow head
pressure to stabilize. This thermostat does not sense AC power
loss and therefore does not activate the short term compressor
protection feature when power is restored.
CAUTION
!
Topreventcompressorand/orpropertydamage, ifthe
outdoor temperature is below 50°F, DO NOT operate
the cooling system.
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.

and HOLD TEMP/ADV DAY buttons until the temperature
display is in Celsius (°C). To display Fahrenheit (°F), repeat
the process.
• 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

batteries are low and should be replaced, the display will be

*
You may only program heating temperatures you have selected into the heating
program and cooling temperatures into the cooling program (for example, you
cannot program the COOL 1 temperature into your heating program).
You may program the temperatures you choose in any order, and you may use the
same temperature in consecutive program periods (for example, you may program
period 1 with temperature 1 and periods 2, 3, and 4 with temperature 2).
You do not have to use all possible temperature choices (for example, you may
want to select temperatures for HEAT 1 and HEAT 2 only – in this case, the HEAT
3 and HEAT 4 temperatures would stay the same as previously programmed).
• TEMPERATURE DISPLAY ADJUSTMENT — Your new

if you wish, you may adjust your new thermostat tempera-
ture display to match your old thermostat. This can be
accomplished (within a ±4° range) as follows:
2. Determine the time periods during which you will program
the temperatures you have just selected. You must program
four periods for each day (periods 1, 2, 3, and 4). However,
you may use the same heating and cooling temperatures for
consecutive time periods. Also keep in mind that, for any
given day, you can only program one set of times for both
heating and cooling (for example, if you select 5:00 AM to
begin heating period 1 on Monday, then your cooling period
1 for Monday will also begin at 5:00 AM). However, you may
select different time periods for each day separately (for
example, heating/cooling period 1 on Monday may begin at
5:00 AM, but heating/cooling period 1 on Saturday may
beginat9:00AM).Usethetableonthefollowingpagetoplan
