Your new White-Rodgers 5-Day/1-Day/1-Day Digital Thermo-

stat 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.

Features:Features:

Features:

• Separate 5-day (weekday), 1-day (Sat) and 1-day (Sun) pro-

gramming with four separate time/temperature periods per day

• Simultaneous heat and cool program storage

• Preprogrammed temperature control

• Backlit display

• LCD continuously displays setpoint, and alternately dis-

plays time and room temperature

PRECAUTIONSPRECAUTIONS

PRECAUTIONS

This thermostat is intended for use with a low voltage system; do

not use this thermostat with a 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.

Do not exceed the specification ratings.

All wiring must conform to local and national electrical codes and

ordinances.

This control is a precision instrument, and should be handled

carefully. Rough handling or distorting components could cause

the control to malfunction.

Do not open mercury cells. If a cell becomes damaged, do not

touch any spilled mercury. Wearing nonabsorbent gloves, take

up the spilled mercury with sand or other absorbent material and

place into a container which can be sealed. If a cell becomes

damaged, the unit should be discarded.

Mercury must not be discarded in household trash. When the

HEAT PUMP SYSTEMSHEAT PUMP SYSTEMS

HEAT PUMP SYSTEMS

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. 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

ELECTRIC/GASELECTRIC/GAS

ELECTRIC/GAS

switch switch

switch on the back of the thermostat (see fig. 1) and switch it to

the

ELECTRIC ELECTRIC

ELECTRIC position. This will allow the thermostat to

energize the fan immediately on a call for heat. If you are unsure

if the heating/cooling system requires the thermostat to control

the fan, contact a qualified heating and air conditioning service

person.

ATTACH THERMOSTAT BASE TO WALLATTACH THERMOSTAT BASE TO WALL

ATTACH THERMOSTAT BASE TO WALL

1. Remove the packing material from the thermostat. Gently

pull the cover straight off the base. Forcing or prying on the

thermostat will cause damage to the unit. If necessary, move

the electric heat switch (see

ELECTRIC HEAT SYSTEMSELECTRIC HEAT SYSTEMS

ELECTRIC HEAT SYSTEMS,

above).

2. Connect wires beneath terminal screws on base using

appropriate wiring schematic (see figs. 2 through 7).

3. Place base over hole in wall and mark mounting hole

locations on wall using base as a template.

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

5. Fasten base loosely to wall, as shown in fig. 1, using two

mounting screws. Place a level against bottom of base,

adjust until level, and then tighten screws. (Leveling is for

appearance only and will not affect thermostat operation.) If

you are using existing mounting holes, or if holes drilled are

too large and do not allow you to tighten base snugly, use

plastic screw anchors to secure subbase.

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

material (such as fiberglass insulation) to prevent drafts

from affecting thermostat operation.

Select FA or SL (Fast or Slow) Heating Cycle RateSelect FA or SL (Fast or Slow) Heating Cycle Rate

Select FA or SL (Fast or Slow) Heating Cycle Rate - The

FA setting is frequently used for gas, oil or electric heat. The

SL setting produces a longer heating cycle which is nor-

mally for hot water or steam (hydronic) systems. Both

settings produce very accurate temperature control and

can be set to your personal preference. FA cycles the

system just under 1°F and the SL setting cycles at approxi-

mately 1.5°F.

Select Energy Management Recovery OFF or ON -

Energy Management Recovery (EMR) causes the thermo-

stat to start heating or cooling early to make the building

temperature reach the program setpoint at the time you

specify. Heating will start 5 minutes early for every 1° of

temperature required to reach setpoint.

Example:Example:

Example: You select EMR and have your heating pro-

grammed to 65° at night and 70° at 7 AM. If the building

temperature is 65° the difference between 65° and 70° is

5°. Allowing 5 minutes per degree the thermostat setpoint

will change to 70° at 6:35 AM. Cooling allows more time per

degree because it takes longer to reach temperature.

6)6)

Select Compressor Lockout LOC OFF or ONSelect Compressor Lockout LOC OFF or ON

Select Compressor Lockout LOC OFF or ON - Selecting

LOC ON will cause the thermostat to wait 5 minutes before

turning on the compressor if the heating and cooling sys-

tem loses power. It will also wait 5 minutes minimum

between cooling cycles. This is intended to help protect the

compressor from short cycling. Some newer compressors

already have a time delay built in and do not require this

feature. Your compressor manufacturer can tell you if the

feature is already present in their system. When the com-

pressor time delay occurs it will flash the (snowflake icon)

the following guidelines in mind when planning your program.

• When heating (cooling) your building, program the

temperatures 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.

¡PRECAUCIÓN!

Para evitar descargas eléctricas y/o daños al equipo,

desconecte la alimentación eléctrica en la caja de

fusibles o disyuntores principal hasta que haya

nalizado la instalación del sistema.

▲

¡ADVERTENCIA!

No utilizar en circuitos que excedan el voltaje

especicado ya que los voltajes más altos dañarán

el control y pueden causar riesgos de electrocución

o incendio.

No cortocircuite las terminales de la válvula de gas ni

del control principal para probarlos. Un cortocircuito o

una conexión incorrecta dañarán el termostato y podría

causar lesiones personales y/o daños materiales.

La instalación del termostato y de todos los

componentes del sistema debe ajustarse a las normas

del código NEC para los circuitos Clase II.
