IMPORTANT: Although the thermostat has a
low battery indicator, replace the batteries
once a year to prevent leakage and to prevent
the thermostat and heating/cooling system
from shutting down due to lack of battery
power.
As a precaution when leaving home for longer
than a month, change batteries before you leave
to prevent system from shutting down due to lack
of battery power.
Use fresh alkaline batteries; nonalkaline bat-
teries do not last as long, and may leak, causing
damage to the thermostat or the wall surface.
We recommend Energizer
®
batteries.
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
you choose conventional recovery, adjust screw
3A (on the back of the thermostat) by turning
out
one turn.
With Adaptive Intelligent Recovery™, your home
gradually reaches the comfort temperature you
set at the exact time programmed into the ther-
mostat to achieve maximum energy savings and
comfort.

for the thermostat to adjust to the weather, your
lifestyle, home construction and heating/cooling
system.
With conventional recovery, the programmed time
marks 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 varies as the seasons change, but 30
minutes is a good head start time to use.
NOTE: If you adjust screw
3A for conventional re-
covery, a
■ ■ indicator
appears in the lower
right corner of the ther-
mostat display as a re-
minder that you are no longer using the Adap-
tive Intelligent Recovery™ feature.

M2483
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) the temperature of
the wall and (3) when you want the comfort
temperature established.
During recovery, the thermostat increases the
control temperature gradually and turns the equip-
ment on and off several times
before reaching
your comfort time to save energy by avoiding
overshooting the comfort temperature. You can
see the current control temperature anytime dur-
ing recovery by pressing the CURRENT SET-
TING 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
normally takes
four to eight days after installation
