WITH ADAPTIVE INTELLIGENT RECOVERY™
Congratulations! You made a smart choice when you purchased your new Honeywell Thermostat.
It’s the smart thermostat that:
■ Keeps you comfortable by automatically calculating exactly when the furnace or air condition-
ing should go on to have the house at the desired comfort temperature by the time you wake
up or return home.
■
Saves the maximum amount of energy and money by remembering to automatically adjust
the heat or air conditioning when you leave home or go to sleep.
■ Provides the ultimate in comfort and convenience . It comes already programmed, so it’s your
choice—use the preprogrammed schedule or set your own.
We invite you to spend a few minutes reading this manual. You’ll find it answers many of the

■Disconnect wires from old thermostat or
subbase. As you disconnect each wire, use
masking tape to label it with the old terminal
designation. If there are only two wires, they do
not need to be labeled. Wrap wires around
pencil to keep them
from falling back into
the wall, as shown.

■Test to make certain that your heating and
cooling systems are working properly. If either
does not work, contact your local heating/air
conditioning dealer. To avoid compressor dam-
age, do not operate the cooling system when
outdoor temperature is below 50°F [10°C].
■
Turn off power to system at the furnace, or
at the fuse/circuit breaker panel.
■Carefully unpack your new thermostat and
wallplate; save package of screws, instructions
and receipt.
■Removethecover from the old thermostat. If
it does not snap off when pulled firmly from the
bottom, check for a screw used to lock on the
cover.
■Loosen screws holding thermostat to sub-

Six or more wires?
If there are six or more wires (excluding clock
wires attached to terminals), you most likely
have a variation of a heat pump or multistage
system. The thermostat is
not compatible with
such systems so return the product to the place
of purchase.

Install the Batteries
IMPORTANT: Three AA alkaline batteries are
included with the thermostat. Batteries must
beinstalledforprogramming and operation of
the thermostat and heating/cooling system.
■Install the batteries in back of the thermostat
as shown, making sure positive (+) terminals all
face toward the right.
As the batteries are running low, a REPL BAT
indicator will flash for 1 to 2 months before bat-
teries run out completely. Replace the batteries
as soon as possible after the indicator starts
flashing.
If you insert new batteries within 20 to 30 sec-
ondsofremovingtheoldones,youwillnothave
to reprogram the thermostat. However, if the
display is blank, the batteries are dead or
incorrectly installed. In this case, you will
have to reprogram. See pages 13 through 15
to reprogram. If you do not reprogram, the
factory-prepro-

IMPORTANT: Although the thermostat has a
low battery indicator, replace the batteries
once a year to prevent the thermostat and
heating/cooling system from shutting down
due to lack of battery power.
When leaving home for longer than a month, as
aprecaution,changebatteriesbeforeyouleave

Use fresh alkaline batteries; nonalkaline bat-
teries will not last as long. We recommend

Adaptive Intelligent Recovery™
Selection
Before you program your thermostat, you must
decide if you want to leave the thermostat at
the factory-set Adaptive Intelligent Recovery™
setting, or adjust it to conventional recovery. If
youchooseconventionalrecovery,adjustscrew
3A (on the back of the thermostat) by turning
OUT one turn.
WithAdaptiveIntelligentRecovery™,yourhome
will reach the comfort temperature gradually to
be at the temperature you set at the exact time
programmed into the thermostat. Maximum en-
ergy savings and comfort will be achieved.
More about Adaptive Intelligent
Recovery™…
This thermostat is actually a small but powerful
computer. When calculating the exact time to
turnon your furnace or air conditioner,it consid-
ers: (1) air temperature, (2) the temperature of
the wall and (3) when you want the comfort
temperature established.
869-0733B—1
During recovery, the thermostat increases the
control temperature gradually and turns the
equipment on and off several times BEFORE
reaching your comfort time to save energy by
avoidingovershooting the comfort temperature.
You can see the current control temperature
anytime during recovery by pressing the CUR-
RENT 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
normallytakesFOURTOEIGHTDAYSAFTER
INSTALLATION for the thermostat to adjust to
the weather, your lifestyle, home construction
and heating/cooling system.
With conventional recovery, the programmed
time will mark the start of the time your furnace
or air conditioner comes on to start recovery;
therefore, you should program the start time to
be earlier than the desired comfort time. The
best starting time will vary as the seasons
change, but 30 minutes is a good head start
time to use.

STEP 6 Adjust System On-Length, Clock Display, As
Required
■The thermostat on-length is factory-set for
awarmair,gasoroilheatingsystem.Ifyouare
installing it on another type of system, the on-
lengthmustbeadjustedaccordinglybysetting
screws 1A and 1B on the back of the thermo-
stat, using the heating system table in the
figure as a guide. The on-length should be
optimized with the type of system to minimize
room temperature swings. Setting the screw out
one turn means turning the screw approxi-
mately 360°, or about one complete turn.
In the rare event that you want a longer on-
length, you may readjust the screws as follows,
but be aware that you may be increasing room
temperature swings at the same time.
If on-length screws 1A,1B are adjusted For longer on-length, readjust
to match this system: screws 1A,1B to match this system:
