Planning Program Schedule
The thermostat display shows day, time,
program period, and temperature.
The thermostat can be set for four time
periods per day for weekdays and weekend.
Before programming the thermostat, you can
use the program schedule to plan your
program.
Fill in the weekday and weekend times and
temperatures you desire. If you decide not to
program the thermostat, it uses the
preprogrammed time and temperature settings
in Table 1.

Programming Thermostat
The thermostat is flexible and can be program-
med for different schedules for weekdays and the
weekend to meet your lifestyle needs.
Use the personal Program Schedule for planning
your time and temperature settings for various
times of the day.
Four time periods are available during weekdays
and the weekend—Wake, Leave, Return, and
Sleep.
Wake is the time the thermostat turns on the
heating/cooling equipment after an energy
saving period. When deciding what time to
set for your Wake period, include extra
lead time, depending on the outside temp-
erature and your equipment response
time, to give the equipment a head start to
heat or cool the house before you get up.
(This will be a higher temperature during
heating season, and a lower temperature
during cooling season.)
Leave is the time period you can set for an
energy-saving temperature while you are
away at work or school. (This will be a
lower temperature during heating season,
and a higher temperature during cooling
season.)
Return is the time the thermostat turns on the
heating/cooling equipment after an energy
saving period. When deciding what time to
set for your Return period, include extra
lead time, depending on the outside temp-
erature and your equipment response time,
to give the equipment a head start to heat
or cool the house before you arrive home.

sleeping. (For more comfortable sleep-
ing, some people choose not to raise the
