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
be oi heating and cooling costs
when you’re asleep or away. Also
called the setback (heating) or setup
(cooling) temperature.
Period key
Ona of the four kevs-WAKE. LEAVE.
RETURN or SLEEP-that you press
to check or program the Start time
and temperature for a time period.
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
davs 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 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!emperature in the
house for a set period every day in
winter for energy savings. The lower
temperature is the energy savings
temperature.
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.
Time oeriod
One~df 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 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 (winier) or up
(summer) the temperature for
energy savings because the
family is sleeping. Set it to stait at
your lamily’s normal bedtime.
Often the SLEEP program is set
only for the heating season so
family members can sleep cool in
?unmer.
Weekday program schedule
