Programming heating/cooling
1. Press PRGM twice. The thermostat enters cooling programming mode
(COOL displays). If you want to program heating, press MODE (HEAT
displays).
Programming starts with the weekday schedule. The programmed
temperature for the rst period (MOR) ashes.
2. Press or to select the desired temperature for the MOR period.
3. Press SELECT. The programmed start time for the MOR period ashes.
4. Press or to select the desired start time for the MOR period. The
time changes in 15 minute increments.
5. Press SELECT to change back to the temperature ashing rst before
changing to the next time of day period.
6. Press PRGM to move on to the next period (DAY). The programmed
temperature for the DAY period ashes.
7. Repeat steps 2-5 to select the temperature and start time for the DAY
period.
8. Press PRGM and repeat steps 2-5 for the EVE and NHT periods.
9. Press PRGM to move on to the weekend schedule.
10. Repeat steps 2-8 to program the periods of the day for the weekend
schedule.
11. If you want to program any days of the week individually, press PRGM one
or more times to select the day you want to program. The individual day
schedule overrides the weekday or weekend schedule for the selected day.
12. Repeat steps 2-8 to program the selected day.
13. Repeat for any additional days you want to program individually.
14. Press RUN when you are done programming.
Your thermostat is now ready to provide maximum comfort and efciency.
Batteries: Batteries are not required to keep your programming data. With 2
optional AA batteries installed, your thermostat will maintain the day and time
and will continuously display the room temperature during a loss of AC power.
Clock: The clock on your thermostat is updated automatically every 24 hours
by the system. As long as your thermostat has functioning batteries, you should
not need to change the time setting.
Periods of the Day
Your thermostat allows
you to program 4 different
periods of the day. You
select the start time and
temperature for each
period.
• MOR (Morning)
• DAY
• EVE (Evening)
• NHT (Night)
Press PRGM to cycle
through the periods.
Day of the
Week Groups
You can program days of
the week individually or in
groups, to create heating
and cooling programs that
work with your schedule.
• Weekday schedule –
Programs all 5 week-
days together (displays
as MO TU WE TH FR)
• Weekend schedule –
Programs Saturday
and Sunday together
(displays as SA SU)
• Individual day schedule
Each day or group includes
the 4 periods described
above.
Press PRGM to cycle through
the days and periods.
Hints:
• If you don’t want to program a particular day or group, you can skip it.
Press PRGM one or more times until you reach the desired day or group.
• If you want to program the days in a group basically the same with only
slight differences, program the group rst, then program individual days
as needed. The individual day program overrides the group program.
• At any point in the programming process, you can switch between
heating and cooling programs by pressing MODE.
If the temperature shows “--” while in the programming mode for a group of days, it indicates that
at least one of the days in the group has a different temperature program than the other days. If
the time shows “--:--” while in the programming mode for a group, it indicates that at least one of
the days in the group has a different period start time than the other days. To nd out which one
is different, press PRGM to cycle through the individual days. You can make the setting the same
for all the days within the group by changing the item (setpoint or time).

Will SMECO CoolSentry affect my comfort level?
During the course of a conservation event, the typical temperature in your facility may rise a few
degrees, a change most customers in similar programs report they do not notice.
How will I know when a SMECO CoolSentry conservation event is occurring?
Check your programmable thermostat. When a conservation event occurs, the LED will illuminate for
the duration of the event and the display will read “SAVE” when energy conservation is taking place.
How often will SMECO CoolSentry events occur?
Conservation events will only occur during times of peak electricity demand, generally on extremely
hot weekday afternoons (between 1 p.m. and 8 p.m.) from June 1 through September 30. You can
expect about 100 hours of events per season. The number of events can vary and an event can last up
to 6 hours. Typically, the program is not activated on weekends or holidays unless there is a system
peak or emergency.
What causes “times of peak electricity demand”?
Peak demand times occur when everyone uses a lot of electricity at the same time. The frequency
of peak demand periods has increased as our population and the use of electric appliances have
grown—and both have grown tremendously in Southern Maryland over the past 30 years.
Will I be able to choose not to participate in any single conservation event?
Yes. Should you decide to do so, simply call 866-921-9474 and speak with a SMECO CoolSentry
customer service representative.
How will I save more money with SMECO CoolSentry?
Your programmable thermostat could help you save up to 10% off your annual heating/cooling bills.*
In addition, you will earn $50 for your full participation over the cooling season—that’s $25 more than
participants with central air conditioning earned on the previous Load Management program!
Whom do I call if I need help?
SMECO has contracted with Comverge, Inc. to administer the program. Should you ever have a question
or concern about your participation in SMECO CoolSentry, call Comverge toll-free at 866-921-9474,
Monday through Friday, 8 a.m. to 6 p.m. for prompt customer service and technical assistance.
