Programmed Recovery

PROGRAMMED RECOVERY—

BREAK-THROUGH TECHNOLOGY

SENSES TEMPERATURE MORE LIKE YOU DO

M168

Your new thermostat is so smart, it’s almost human.

■Your body perceives temperature from a variety of

sources, not only from the air in the zone, but also from

your surroundings—walls, windows and furnishings.

■Human beings feel differences in temperature as

slight as two degrees Fahrenheit.

■Common household thermometers and standard

thermostats sense only air temperature, which may

or may not reflect how hot or cold the zone actually

feels to a human being.

■Your new thermostat reads the temperature of the wall

as well as the air—and responds to temperature

changes as little as one degree Fahrenheit—so zone

temperature is more likely to feel right to you and

your family.

THE OPTIMUM COMFORT AND ENERGY SAVINGS

SOLUTION

■

This thermostat is actually a small but powerful

computer.

When calculating the exact time to turn on

your furnace or air conditioner, it considers: (1) air

temperature, (2) temperature of the wall and (3) when

you want the comfort temperature established.

4 69-0819

■

During programmed recovery, the thermostat

gradually increases the control temperature and

turns the equipment on and off

several times to save

energy by avoiding

overshooting

the comfort

temperature. You can see the current control

temperature anytime during recovery by pressing the

PRESENT SETTING key.

■

This smart control learns from experience

. Each day it

checks how closely it

hit the target

and adjusts the

recovery start time accordingly.

It typically takes four to eight days after installation for

this thermostat to adjust to the weather, your life style,

home construction and heating/cooling system. The

thermostat calculates the LEAVE/RETURN recovery

separately from the SLEEP/WAKE recovery.

IMPORTANT:

With Programmed Recovery, program the

times when you want your home comfortable. The

thermostat will decide how early to begin the

temperature changes.

NOTE: Some models will show 32°F instead of the current

temperature, indicating the thermostat is operating on

backup batteries until the thermostat is mounted on the

wallplate and the system is powered.

Programming Your Thermostat

The thermostat can be programmed in your hand

before it is installed or after it is on the wall if you make

sure the batteries are installed. If you need to install or

replace the batteries, refer to the Maintaining Your

Thermostat section.

Your thermostat can be programmed for seven days

(separate programs for each day of the week).

PROGRAMMING

The personal programming chart can be helpful for

plannng your program schedule of time and temperature

settings for various times of the day.

Four time periods are available:

MORNING is the time period when you want the zone

at a comfortable temperature to begin the day. (This

will be a higher temperature during the heating

season, or a lower temperature during the cooling

season.) This is the only period that must contain a

time and temperature for every day.

MIDDAY is the time period you can set for an energy-

saving temperature while the zone is unoccupied.

(This will be a lower temperature during the heating

season, or a higher temperature during the cooling

season.)

EVENING is the time period when you want the zone

at a comfortable temperature for family activities in

the evening.

NIGHT is the time period you can set for an energy-

saving temperature while you are sleeping or the

zone is unoccupied. Set it to start at your family’s

normal bedtime. (For more comfortable sleeping in

the cooling season, some people choose not to

raise the cooling temperature during the night.)

You can set a different schedule for each day of the

week because your requirements will probably be

different for each day.

Fill in the times and temperatures you desire for each

day of the week. If you decide not to program the

7 69-0819

thermostat, it will automatically control heating from

6:00 AM to 10:00 PM at 70°F [21°C]. The temperature

will be 60°F [16°C] from 10:00 PM to 6:00 AM. Cooling is

automatically controlled 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 zone that is occupied Monday and

Tuesday only requires programs for MORNING and

NIGHT.

IMPORTANT:

Always press the keys with your finger or

similar blunt tool. Use of sharp instruments like a

pen or pencil point can damage the keyboard.

If you make an error at any time during programming,

just press the RUN PROGRAM key, and continue at the

step where you left off.
