THE OPTIMUM COMFORT AND
ENERGY SAVINGS SOLUTION
■
This thermostat is actually a small but powerful computer
. When calculat-
ing 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.
■
During the Adaptive Intelligent Recovery
setting,
the thermostat in-
creases 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 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.
■
With the T8631A, you can choose
whether you want to use Adaptive
Intelligent Recovery™ or conventional recovery. Use the Adaptive
Intelligent Recovery setting if you want to choose the exact time that the
room reaches your
comfort temperature.
Use
conventional recovery
if
you prefer to choose the exact time your furnace or air conditioner
comes
on
to start recovery.
