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 Single Stage Digital

Thermostat uses the technology of a solid-state microcomputer

to provide precise time/temperature control. This thermostat

offers you the flexibility to design heating and cooling programs

that fit your needs.

• Optional Energy Management Recovery (EMR)

• Optional B and O terminals

• Preprogrammed temperature control

• LCD continuously displays set point, and alternately dis-

plays time and room temperature

• Temperature override until next program period

• Manual program override (HOLD temperature)

• °F/°C convertibility

Features:

• Separate 5-day (weekday) and 2-day (weekend) programming

with four separate time/temperature periods per program

• Temperature range 45° to 90°F

• Keypad lockout

• Armchair programming capability

• Simultaneous heat and cool program storage

• Automatic changeover

• Optional C terminal (dual power option)

PRECAUTIONS

CAUTION

Thisthermostatisintendedforusewitha24-voltsystem;donot

use this thermostat with a millivolt or line voltage system. If in

doubt about whether your wiring is millivolt, line, or low voltage,

have it inspected by a qualified heating and air conditioning

contractor or electrician.

To prevent electrical shock and/or equipment damage

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.

REMOVE OLD THERMOSTAT

1. Shut off electricity at the main fuse box until installation is

complete. Ensure that electrical power is disconnected.

2. Remove the front cover of the old thermostat. With wires

still attached, remove wall plate from the wall. If the old

PRE-INSTALLATION SET-UP

Figure 1. Back of thermostat base

1. Remove the packing material from the thermostat.

Alkaline batteries (3 “AA”–

install “+” ends to the left)

2. This thermostat is configured from the factory to operate a

heat/cool, fossil fuel (gas, oil, etc.), forced air system. It is

configured correctly for any system that DOES NOT require

the thermostat to energize the fan on a call for heat.

Screw anchors

If your system is an electric heat or heat-pump system that

REQUIRES the thermostat to turn on the fan on a call for

heat, locate the GAS/ELECTRIC switch on the back of the

thermostat (see fig. 1) and switch it to the ELECTRIC

position. This will allow the thermostat to energize the fan

immediatelyonacallforheat.Ifyouareunsureiftheheating/

cooling system requires the thermostat to control the fan,

contact a qualified heating and air conditioning service

person.

3. Two jumpers are also located on the back of the thermostat,

so that you may customize the thermostat to meet your

individual preference (see fig. 1). In most applications, the

factory jumper settings provide the most comfortable and

convenient thermostat operation.

Mounting

holes

Figure 2. Thermostat base

Jumper wire W905 determines how fast the system cycles

on and off, based on temperature change. As shipped from

the factory, the thermostat will maintain a very consistent

room temperature, usually within 1°F of the thermostat

setting. To achieve a slower on and off cycle, providing a

slightly wider temperature span, cut and separate jumper

wire W905.

INSTALLING THE THERMOSTAT

1. Gently remove the cover by pulling it straight off the base.

Forcing or prying on the unit may cause damage to the unit.

2. Remove the battery tab. With the batteries installed, the

Armchair Programming feature allows you to program the

thermostat before installing it on the wall.

JumperwireW903controlstheEnergyManagementRecov-

ery (EMR) feature. EMR allows the thermostat to energize

the heating system up to 30 minutes before the time pro-

grammed into the thermostat. The thermostat will then

energize the system to gradually raise the temperature to

your programmed temperature by using the most efficient

stage of heat practical.

3. Pull wires through the hole in the thermostat base and place

the base over the hole in the wall. Mark mounting hole

locations on the wall using the base as a template.

4. Move the base out of the way. Drill mounting holes.

For example, assume that the thermostat is programmed

overnightto66°Fandtheroomtemperatureis66°. Ifthenext

programis7AM, 70°F(anincreaseof4°), thethermostatwill

start the system 30 minutes before 7 AM. If the temperature

in the room is within 2°F of your next programmed tempera-

ture, the thermostat will not start the system early.

5. Fasten the base loosely to the wall, as shown in fig. 2, using

two mounting screws. Place a level against the bottom of the

base, adjust until level, and then tighten the screws. (Level-

ing is for appearance only and will not affect thermostat

operation.) If you are using existing mounting holes, or if the

holes drilled are too large and do not allow you to tighten the

base snugly, use plastic screw anchors to secure the base.

DO NOT clip jumper wire W903 unless you wish to perma-

nently disable the EMR feature.

6. Check that the system is turned off. Connect the wires

beneath the terminal screws on the base using the appropri-

ate wiring diagram (see figs. 3 through 5).

7. Push excess wire into wall and plug hole with a fire-resistant

material(suchasfiberglassinsulation)topreventdraftsfrom

affecting thermostat operation.

If your thermostat’s display is frozen or displaying incorrectly,

the thermostat may have been affected by static discharge or

voltagevariations. Ifthishappens, presstheRESETbutton(see

fig. 2, page 2 for the location of the button). Pressing the RESET

buttonwillclearalluserprogramming. Thethermostatwillrevert

to factory preprogramming. You will need to reset the time and,

if desired, reprogram the thermostat to your selected program.

If pressing the RESET button does not correct the problem,

contact a qualified service technician.

programming.

11.When you have completed entering your heating program,

press RUN PRGM.

Enter Cooling Program

CAUTION

For optimum performance, we recommend replacing batteries

once a year with fresh “AA” Energizer^®alkaline batteries.

If the outside temperature is below 50°F, disconnect

power to the cooling system before programming.

Energizing the air conditioner compressor during

cold weather may cause personal injury or property

damage.

1. Press SYSTEM button until COOL is displayed.

2. Follow the procedure for entering your heating program,

using your selected cooling times and temperatures.
