backlight OFF (default) will keep the light off. Turn the dis-
play backlight feature ON as follows:

This section will help you plan your thermostat’s program to meet 
your needs. For maximum comfort and efficiency, keep the follow-
ing guidelines in mind when planning your program.
•  When  heating  (cooling)  your  building,  program  the  tempera-
tures to be cooler (warmer) when the building is vacant or dur-
ing 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 
button to begin running the factory preset program.
If you want to change the preprogrammed times and temperatures, 
follow these steps.
Determine  the  time  periods  and  temperatures  for  your  weekday 
and weekend programs. You must program four periods for both the 
weekday and weekend program. However, you may use the same 
heating and cooling temperatures for consecutive time periods. You 
can  choose  start  times,  heating  temperatures,  and  cooling  tem-
peratures 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.
