• RESET BUTTON - (see fig. 2) resets the thermostat pro-
gram to the factory setting. This button can be used if you
do not like the program you have entered or if you wish to
start over in the programming procedure. The reset button
can also be used to reset the program if the thermostat has
been subjected to a voltage spike and the program has
become scrambled or frozen.
PROGRAMMING YOUR THERMOSTAT
Now you are ready to program your thermostat. This section will
help you plan your thermostat’s program to meet your needs.
For maximum comfort and efficiency, keep the following guide-
lines in mind when planning your program.
• When heating (cooling) your building, program the tem-
peratures to be cooler (warmer) when the building is vacant
or during periods of low activity.
• During early morning hours, the need for cooling is usually
minimal.
Look at the factory preprogrammed times and temperatures
shown below. If this program will suit your needs, simply press
the RUN PRGM button to begin running the factory preset
program.
If you want to change the preprogrammed times and tempera-
tures, follow these steps.
1. Determine the heating and cooling temperatures you want to
use. You may select up to four heating temperatures (HEAT
1, HEAT 2, HEAT 3, and HEAT 4), and up to four cooling
temperatures (COOL 1, COOL 2, COOL 3, and COOL 4).
Use the table below to write down the temperatures you have
selected.
2. Determine the time periods during which you will program
the temperatures you have just selected. You must program
four periods for each day (periods 1, 2, 3, and 4). However,
you may use the same heating and cooling temperatures for
consecutive time periods. Also keep in mind that, for any
given day, you can only program one set of times for both
heating and cooling (for example, if you select 5:00 AM to
begin heating period 1 on Monday, then your cooling period
1 for Monday will also begin at 5:00 AM). However, you may
select different time periods for each day separately (for
example, heating/cooling period 1 on Monday may begin at
5:00 AM, but heating/cooling period 1 on Saturday may
begin at 9:00 AM). Use the table on the following page to plan
your program time periods, and the temperatures you want
during each period. You may also want to look at the sample
program table to get an idea of how the thermostat can be
programmed.
ENTERING YOUR PROGRAM
Set Current Time and Day
1. Press SET TIME/SET TEMP button once. The display will
show the hour only.
EXAMPLE:
PM
2. Press and hold either or until you reach the correct
hour and AM/PM designation (AM begins at midnight; PM
begins at noon).
3. Press SET TIME/SET TEMP once. The display window will
show the minutes only.
EXAMPLE:
4. Press and hold either or until you reach the correct
minutes.
5. Press SET TIME/SET TEMP once. The display will show the
day of the week.
6. Press or until you reach the current day of the week.
7. Press RUN PRGM once. The display will show the correct
time and room temperature alternately.
Select Heating Temperatures
1. If you want to change the display from Fahrenheit to Celsius
(or vice-versa), press SET TIME/SET TEMP and HOLD
TEMP/ADV DAY at the same time.
2. Move the SYSTEM switch to HEAT.
3. Press SET TIME/SET TEMP four times. The display will
show the number 1, along with the currently programmed
HEAT 1 temperature.
EXAMPLE:
HEAT
4. Press or to change the displayed temperature to your
selected HEAT 1 setting (if you only want to program a
temperature for HEAT 1, skip to step 8).
5. Press SET TIME/SET TEMP once. The number 1 will
change to the number 2, representing HEAT 2.
6. Press or until you reach your selected HEAT 2
temperature.
7. Repeat steps 5 and 6 to select HEAT 3 and HEAT 4
temperature settings, if desired.
8. Press RUN PRGM.

FACTORY PREPROGRAMMING
* You may only program heating temperatures you have selected into the heating
program and cooling temperatures into the cooling program (for example, you
cannot program the COOL 1 temperature into your heating program). You may
program the temperatures you choose in any order, and you may use the same
temperature in consecutive program periods (for example, you may program
period 1 with temperature 1 and periods 2, 3, and 4 with temperature 2). You do
not have to use all possible temperature choices (for example, you may want to
select temperatures for HEAT 1 and HEAT 2 only – in this case, the HEAT 3 and
HEAT 4 temperatures would stay the same as previously programmed).
