White Rodgers 1F97W 51 Thermostat User Manual

About Your New Thermostat . . .

Your new White-Rodgers 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.

Please read this manual thoroughly before operating or programming your thermostat. If you have

questions, write to us at the address shown on the back cover of this manual.

NOT FORCE OR PRY THE THERMOSTAT, as

this may damage the unit.

Your thermostat consists of two parts: the ther-

CAUTION

Remove power from the system at the

circuit breaker/fuse box before remov-

ing or attaching the thermostat body.

Equipment damage and/or personal in-

The Back of The Thermostat Body

Turn the thermostat body over. On the back are

the 3 “AA” Energizer^®alkaline batteries.

The “AA” Energizer^®alkaline batteries provide

powertothethermostatwhenthe24VACpower

is interrupted (for example, when you remove

the thermostat from the wall for programming).

Fresh batteries will maintain the stored program

for approximately a year. If power loss is long

enough for the program to be lost, the thermo-

stat will automatically return to the factory pro-

grammed temperatures (64°F heating and 82°F

cooling) when power is restored. You must

reprogram the thermostat if this happens.

OPERATING FEATURES

Now that you are familiar with the thermostat

display and buttons, read the following informa-

tion to learn about the many features of the

thermostat.

The thermostat is configured at the factory

so that this feature is disabled. If you wish to

have this feature, refer to the installation

instructions for this thermostat, or contact

your local heating/cooling contractor.

• COMPUTED ENERGY MANAGEMENT

RECOVERY (EMR) — The thermostat’s

microcomputer can be set to automatically

calculate the time it will take to change the

temperature to the next program setting.

Then the thermostat will activate the heat-

ing or cooling system to change the tem-

perature so that the desired temperature is

reached at the beginning of the next pro-

gram period. As an example of this feature,

assume that you have programmed your

thermostat to provide an overnight heating

temperature of 62°F, and that during the

next program period, beginning at 6:00 AM,

• TWO HOUR TEMPERATURE OVERRIDE

— Press

until the display

shows the temperature you want. The ther-

mostat will override current programming

and keep the room temperature at the se-

lected temperature for two hours. After two

hours, the thermostat will automatically re-

vert to the program.

can hold any temperature within its range

for an indefinite period, without reverting to

Whenever adjusting anticipation, increase

a while to see if the adjustment is sufficient.

TIME

• LOW BATTERY INDICATOR — The three

“AA” alkaline batteries will maintain thermo-

stat programming for approximately one

year if power to the thermostat fails. The

word BATTERY will flash on the display if

the“AA”alkalinebatteriesarelowandshould

be replaced. The thermostat will also make

a beeping sound every five minutes when

batteries need replacing. To override the

beeping, press any button on the keypad.

pressing any button on the keypad. After

stat will quit beeping. However, you should

always change the batteries as soon as

possible to ensure that programming will

not be lost in the event of a power outage.

You should also change the batteries at

least once a year.

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 B and periods 2, 3,

6. What can cause the thermostat display

to freeze or go blank?

A completely blank display may indicate

that power has been lost to the thermostat

and the backup batteries are also dead.

However, if there is power to the thermostat

may reprogram the thermostat, then re-

place it on the wall.

During periods of low humidity (especially

during cold weather), you may feel or see a

spark discharge when you touch the ther-

mostat. This may cause the program to be

lost or the thermostat to display incorrectly.

To correct this, remove the thermostat from

the wall and disconnect the batteries. Wait

about two minutes, then reconnect the bat-

teries. The thermostat will revert to the fac-

tory preset program until you reprogram the

thermostat. If you don’t want to reprogram

though the thermostat display is func-
