• TEMPERATURE DISPLAY ADJUSTMENT — Your new
thermostat has been accurately set in our factory. However,
if you wish, you may adjust your new thermostat tempera-
ture display to match your old thermostat. This can be
accomplished (within a
±
4
°
F range) as follows:
1. Press VIEW PRGM and HOLD TEMP buttons at the
same time.
2. Press
or
to adjust the displayed temperature to
your desired setting.
3. Press RUN PRGM to resume normal program operation.
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.
Determine the time periods and heating and cooling tempera-
tures for your weekday and weekend programs. You must
program four periods for both the weekday and weekend pro-
gram. However, you may use the same heating and cooling
temperatures for consecutive time periods. You can choose
start times, heating temperatures, and cooling temperatures
independently for both weekday and weekend programs (for
example, you may select 5:00 AM and 70
°
as the weekday 1st
period heating start time and temperature, and also choose
7:00 AM and 76
°
as the weekday 1st period cooling start time
and temperature).
Use the table at the bottom of the 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.
