Choose a day to program first.
We’ll use Monday in the exam-
ples, but you can start with any
day. Start by programming the

shows 1:00 PM Mon.
Press and hold until the current
day appears in the display.
TIME
Press and hold until the current
time appears in the display. Be
sure AM or PM appears as
desired.
You have set the current day and
time. Go on to Step 2.
1
Press and release. Note that the
display shows MORNING and
the preprogrammed time and
temperature.
If the display reads COOL, press
and release to switch to HEAT.
Press and hold until MONDAY
(or the desired day) appears in
the display.
Press and hold until the
display
shows the time you want the
temperature at the comfort
setting.
Press and hold until the display
shows the desired heating
temperature.
If the display flashes while you
are holding down TEMPERA-
TURE WARMER or COOLER,
you have reached the setting
limit. If your thermostat can
switch automatically between
heating and cooling, the heating
temperature must be at least 3
degrees below the air condition-
ing temperature. For example, if
the cooling setting is F, the
maximum heating setting is 72”
F. To set a higher heating
temperature, you must first raise
the cooling setting.
Program the MIDDAY time and
heating temperature if desired.
NOTE: You can cancel any
period showing on the display
except MORNING by pushing
the the CANCEL key.
To move to the next period
while programming, simply
press the PERIOD key again.
Press and release. The display
shows MIDDAY, but no time or
temperature.
Press and hold until the display
shows the time you want room
temperature to start drifting
toward the energy saving setting.
Press and hold until the display
shows the desired temperature.
