Select WAKE if you want the house at a

comfortable temperature when you get up,

while you get ready for work or school. When

deciding what time to set for your WAKE

period, include extra lead time, depending on

the outside temperature and your furnace

response time, to give the furnace a head start

to heat the house before you get up. (This will

be a higher temperature during heating

season, or a lower temperature during cooling

season.)

Programming Thermostat

When you program the thermostat, set one

schedule for weekdays and another for

weekends, because your temperature require-

ments probably vary. (During weekends, only

the WAKE and SLEEP time periods are

available.)

Use the personal Program Schedule for

planning your program schedule of time and

temperature settings for various times of the

day.

Select LEAVE if you want an energy-saving

temperature while you are away at work or

school. (This will be a lower temperature during

heating season, or a higher temperature during

cooling season.)

Four time periods are available during week-

days—WAKE, LEAVE, RETURN, and SLEEP.

View these periods individually on the display

when you press the Set Schedule key.

69-0786—2

Select RETURN if you want the house at a

comfortable temperature for activities before

bedtime. When deciding what time to set for

your RETURN period, include extra lead time,

depending on the outside temperature and

your furnace response time, to give the furnace

a head start to heat the house before you

arrive home. (Again, higher for heating or lower

for cooling.)

controls heating at 68°F (20°C) and cooling at

78°F (26°C), 24 hours a day. Also, you do not

need to enter a time and temperature program

for all periods if your schedule does not require

it. For example, a house that is occupied

during weekdays would not require programs

for LEAVE and RETURN.

When pressing the keys, use the ball of your

finger or a soft pencil eraser.

Select SLEEP if you want an energy-saving

temperature while you are sleeping. (For more

comfortable sleeping, some homeowners

choose not to raise the cool temperature during

the night.)

NOTE: Using sharp fingernails or pencil

points can damage the keypad.

If you make an error at any time during

programming, press the Run Program key,

and continue again at the last step.

Fill in the times and temperatures you desire

for weekdays and weekends. If you decide not

to program the thermostat, it automatically

BATTERIES AS SHOWN

To remove batteries, press down on the left

ends of the batteries. If you insert new batter-

ies within 20 to 30 seconds of removing the old

ones, the thermostat does not require repro-

gramming. However, if the display is blank, the

batteries are dead or incorrectly installed and

the thermostat requires reprogramming.
