OWNER’S GUIDE
Your new programmable thermostat is a precision instrument that’s quality-built to give you many years of satisfactory service. It’s a “smart” thermostat that lets you save energy while still maintaining the standard of comfort you want in your home.
This Owner's Guide will show you how to get the most benefit from your new thermostat.
Monitor thermostat operation, read current time and room temperature at a glance.
Set different schedules for weekdays,
Saturday, and
Sunday.
Choose manual or automatic thermostat operation.
Program up to four different time periods in each schedule.
Features
Check status light to see if the thermostat is on, even in the dark.
Set the temperature warmer or cooler at the touch of a key.
Bypass the stored program for a single period.
Choose system and fan operating modes with the thermostat switches (on subbase).
Simple Four-Step Programming
Of course, you can use the schedule preprogrammed into your new thermostat (see
Glossary, page 35). But it’s an easy matter to program the thermostat to fit your lifestyle.

The Chronotherm
®
III Thermostat is so smart, it’s almost human.
■
Your body perceives temperature from a variety of sources, not only from the air in the room, 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 room actually feels to a human being.
■
The Chronotherm III Thermostat reads the temperature of the wall as well as the air—and responds to temperature changes as little as one degree
Fahrenheit—so room temperature is more likely to feel right to you and your family.

■
The Chronotherm III 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) the temperature of the wall and (3) when you want the comfort temperature established.
3
■
During Adaptive Intelligent Recovery™, the thermostat increases the control temperature gradually 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 the Chronotherm III
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.

PROGRAMMING YOUR THERMOSTAT
With Adaptive Intelligent Recovery™, program the times for 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.

batteries. The display will flash REPL BAT when the batteries get low. Unless the display is blank
(indicating the batteries are dead) when you start, you will not have to reprogram the thermostat if you insert the new batteries within 20-30 seconds of taking out the old ones.
To replace:
■
Set the system switch to OFF.
■
Remove the thermostat from the wall. See page 31.
■
Lift the batteries out of the holder.
■
Insert the new batteries, making sure the positive (+) terminals all face toward the right.
■
Replace the thermostat on the wall. See page 32.
■
Reprogram, if necessary.

POWER OUTAGES
Backup batteries will hold the programming and keep the display on during most power outages. Once the power is restored, the system will resume normal operation.
If the display goes off when power is lost, either the backup batteries need to be replaced or are not installed.
When power is restored, the display will flash 1:00 PM to remind you to reprogram.

Comfort temperature
The temperature you want in the morning and evening when you’re home.
Energy-saving temperature
The lower (heating) or higher
(cooling) temperature that lets you save on heating and cooling costs when you’re asleep or away. Also called the setback (heating) or setup
(cooling) temperature.
Period key
One of the four keys—WAKE,
LEAVE, RETURN or SLEEP—that you press to check or program the start time and temperature for a time period.
GLOSSARY
Preprogrammed schedule
This is the schedule programmed into your thermostat at the factory. It sets a night program that provides energy savings if you don’t set your own program, or if your personal program is lost for any reason. The program, which is the same for all days of the week, is:

Program
The times and temperatures you set to define the comfort and energy savings periods for each schedule
(weekdays, Saturday, Sunday).
Recovery
The time when the thermostat operates the heating or cooling equipment to return the house from the energy savings temperature to the comfort temperature. The thermostat starts the recovery period early so the house will be at the comfort setting by the time you’ve chosen.
Saturday program schedule
The schedule of WAKE, LEAVE,
RETURN and SLEEP period start times and temperatures that you program to run on Saturdays.
Setback
Reducing the temperature in the house for a set period every day in winter for energy savings. The lower temperature is the energy savings temperature.
35
Setup
Raising the temperature in the house for a set period every day in summer for energy savings. The higher temperature is the energy savings temperature.
Set point
The temperature you set on the thermostat. The thermostat turns the heating or cooling equipment on and off to maintain this temperature at the thermostat location until another temperature setting goes into effect.
Sunday program schedule
The schedule of WAKE, LEAVE,
RETURN and SLEEP period start times and temperatures that you program to run on Sundays.
GLOSSARY
SYSTEM light (yellow)
This light (located on thermostat) glows whenever the thermostat is calling for heating or cooling.
Time period
One of four program periods:
WAKE, LEAVE, RETURN and
SLEEP available with the thermostat. One period begins when the previous period ends.
WAKE—The time period when you want the house at a comfortable temperature while the family gets up and gets ready to leave for work or school. This is the only period that must contain a time and temperature.
LEAVE—The time period when you can set back (winter) or set up (summer) the temperature for energy savings because the family is usually away from home.
RETURN—The time period when you want the house at a comfortable temperature for family activities in the evening before bedtime.
SLEEP—The time period when you can set back (winter) or set up (summer) the temperature for energy savings because the family is sleeping. Set it to start at your family’s normal bedtime.
Often the SLEEP program is set only for the heating season so family members can sleep cool in summer.
Weekday program schedule
The schedule of WAKE, LEAVE,
RETURN and SLEEP period start times and temperatures that you program to run Monday through
Friday.

CHRONOTHERM III THERMOSTAT QUESTIONS
1.
The temperature displayed on the Chronotherm III Thermostat doesn’t always match the room temperature on another thermostat located right next to it. Why?
2.
Can I control when the furnace comes on in the morning?
First, the Chronotherm III Thermostat is a very accurate instrument designed to sense both air temperature and wall temperature, like your body does. It gives an average reading over a period of time. Second, it is self-adjusting, and will take a few days after installation to adapt to your home.
3.
What does the HOLD key do?
With Adaptive Intelligent Recovery™, the thermostat will turn on the furnace as early as necessary to reach your desired comfort temperature at the programmed time. The earliest it will be is 24 minutes per degree setback ahead of your WAKE time, but it will vary depending on your system, the weather and how much the temperature dropped in your house during the night.
If it is so cold outside that your house drops to your sleep temperature, the furnace will turn on and off at night to control the temperature at that setting.
It bypasses all program settings and holds the temperature at the present setting. To increase or decrease the temperature while on HOLD, use the
WARMER-COOLER keys. Touching RUN PROGRAM will return the device to programmed operations.
41
4.
How long does the HOLD key hold?
5.
How can this thermostat save energy when it comes on and off so many times early in the morning hours?
6.
7.
Why don’t all thermostat models have AUTO (automatic) changeover from heating to cooling?
Sometimes my Chronotherm
III Thermostat doesn’t allow the house temperature to drop to my SLEEP setting before it starts bringing the furnace on. Why?
Forever! The HOLD key will hold the temperature indefinitely. The only way to release it is to push the RUN PROGRAM key or change the system switch positions if applicable.
Two ways. First, it saves energy (and money) by setting back the temperature for blocks of time during the day or night. Second, it conserves energy by recovering gradually to the desired temperature. This prevents overshooting your comfort set point (and wasting energy) or undershooting the comfort set point (and forcing you to change the thermostat setting, also wasting energy).
Most parts of the country don’t have wide temperature swings during a 24-hour period, so it is not necessary. Desert climates, such as Phoenix, are the exception because of wide variations in temperature that may require both the air conditioner and furnace to run during different times within a given 24-hour period.
When you start your SLEEP period, the thermostat will turn off your furnace and your house temperature will start to fall. After that, the thermostat does nothing until the house temperature falls all the way to your SLEEP temperature setting or until recovery starts.
In mild weather or with good insulation, your house temperature may not fall all the way to your SLEEP temperature setting and the thermostat won’t turn on your furnace until the time to recover back up to your comfort setting.
