THE OPTIMUM COMFORT AND ENERGY SAVINGS
SOLUTION
■
This thermostat is actually a small but powerful com-
puter.
When calculating the exact time to turn on your
furnace or air conditioner, it considers (1) air tempera-
ture, (2) the temperature of the wall and (3) when you
want the comfort temperature established.
■
During programmed recovery, the thermostat gradu-
ally 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 dur-
ing recovery by pressing the TEMPERATURE
REQUISE 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 ther-
mostat calculates the SORTIE/RETOUR recovery sepa-
rately from the COUCHER/REVEIL recovery.
■
With this thermostat you can choose
whether you want
to use Programmed Recovery or conventional recov-
ery. Use Programmed Recovery if you want to choose
the exact time that the room reaches your
comfort
tem-
perature. Use conventional recovery if you prefer to
choose the exact time your furnace or air conditioner
comes
on to start recovery.
IMPORTANT:
With Programmed Recovery, program the
times when you want your home comfortable. The
thermostat will decide how early to begin the tem-
perature changes.
