Step 2: Thermostat Main Menu and Other Settings
C. Description of Programming and Other Settings
Menu Options
The following are detailed descriptions of your Energy Wise Rewards thermostat configuration menu options.
1. Programming – Heat/Cool Programming
The Energy Wise Rewards thermostat can be programmed as a 7-day or 5/2 day thermostat. Using a 7-day
programming profile, you can program each day of the week with its own individual setpoint profile. With a
5/2 day programming profile, Monday–Friday each has the same setpoint profile while Saturday–Sunday can be
programmed with its own setpoint profile.
You can increase or decrease the temperature during the programming cycle, if desired.
2. Other Settings – Backlight
This menu item controls the display backlight. You can choose either:
• AUTO – (Default) Backlight comes on when you press any key. Backlight goes off after a short delay when
there is no button pressed
• ON – Backlight is always On.
3. Other Settings – Temperature Limits
Temperature limits can be used to set limits on how high your heating temperature can be set and how low
your cooling temperature can be set. The range for both values is from 45°F to 99°F.
• Cool Setpoint – 45°F (default)
• Heat Setpoint – 99°F (default)
4. Other Settings – Adjust Temperature Display
This allows you to adjust the displayed temperature up to 5° higher or lower than the actual room temperature.
Your thermostat was accurately calibrated at the factory, but you have the option to change the display
temperature to match your previous thermostat. The current or adjusted room temperature will be displayed on
the left side of the display while your desired offset will be displayed on the right side of the display.
Options for this menu item include:
• +1° through +5° – Adjusts the displayed temperature the specified number of degrees higher than the
measured room temperature.
• 0 – (Default) Displays the measured room temperature.
• –1° through –5° – Adjusts the displayed temperature the specified number of degrees lower than the
measured room temperature.

5. Other Settings – Energy Management Recovery
Options for this menu item include:
• OFF – (Default) The system starts heating or cooling at the start time for the program period.
• ON – The system starts heating or cooling before the start time for the program period so that the room
temperature reaches the program setpoint at the period start time.
Example: You select EMR ON and have your heat (conventional heating system) programmed to 65° at night
and 70° at 7:00 AM (a difference of 5°). Allowing 7 minutes per degree, the thermostat will start calling for
heat prior to the 7:00 AM period start time in an attempt to reach the 70° setpoint by 7:00 AM. With EMR OFF,
the thermostat will wait until the 7:00 AM period start time to begin heating the facility.
6. Other Settings – °F/°C
You can display temperature in either:
• °F – Fahrenheit (Default)
• °C – Celsius
7. Other Settings – “Control Event Pending”
The phrase Control Event Pending will appear in the message rotation at the top of the display screen before
an Energy Wise Rewards conservation period is set to begin. The LED at the center of the control arrows will
flash until the event begins.
8. Other Settings – “Event in Progress”
When an Energy Wise Rewards conservation period is in progress, the phrase Event in Progress will be
displayed in the message rotation at the top of the display screen. The LED at the center of the control arrows
will maintain a steady light for the duration of the event.

PROGRAMMING TIPS:
• If you don’t want to program a particular day, you can skip it. Press NEXT one or more times until you
reach the desired day.
• If you want to similarly program days in a group with only slight differences, program as a group first, then
program individual days as needed. The individual day program overrides the group program.
• While programming the heating or cooling schedule, press the GO TO HEAT or GO TO COOL button
(choose for current schedule being programmed) to save any changes made and display the program
schedule for that mode of operation.
Step 4: Temporary Versus Permanent Hold
A temporary hold can be set when operating in any mode except for OFF. A temporary hold is set by pressing the
or on the thermostat to adjust the desired temperature. The SET AT indication of the temperature setpoint
will change to HOLD AT and a message will be cycled in the thermostat messaging display area to confirm that a
temporary hold is set. A temporary hold setpoint will then be maintained until the start of the next programmed
time period or the RUN soft key is pressed.
A permanent hold can be set when operating in any mode except for OFF. To set a permanent hold, change
the temperature just like setting a temporary hold. When the desired setpoint is entered, the user will have
approximately 4 seconds to press the PERM HOLD soft key to convert the temporary hold into a permanent hold.
The SET AT by the setpoint will change to HOLD AT and a message will be cycled in the thermostat messaging
display area to confirm that a permanent hold is set. If the PERM HOLD soft key is not pressed within 4 seconds,
the hold will remain a temporary hold and the soft key will change to a RUN soft key.
A permanent hold setpoint will override the programmed setpoints and time periods and can only be ended by
pressing the RUN soft key.

period to end.
System switch is set to OFF. Press the thermostat’s SYSTEM button one or more
times to select HEAT or COOL (as appropriate).
Heat, Cool, or Fan Runs Constantly
Possible Cause Corrective Action
Fan set to ON. Change Fan to AUTO.
No Heat/No Cool/No Fan (Common Problems)
Possible Cause Corrective Action
Blown fuse or tripped circuit breaker. Replace fuse or reset breaker.
Furnace power switch set to OFF. Turn switch to ON.
Furnace blower compartment door or panel is loose
or not properly installed.
Replace door panel in proper position to engage
safety interlock or door switch.

Troubleshooting
No Heat
Possible Cause Corrective Action
Pilot light not lit. If it will not stay lit, call for service from your HVAC
contractor.
System switch not set to HEAT. Press the thermostat’s SYSTEM button one or
more times to select HEAT and press to raise the
temperature setpoint above room temperature.
Furnace Lock-Out Condition. Heat may also be
intermittent.
Many furnaces have safety devices that shut down
when a lock-out condition occurs. If the heat works
intermittently, contact the furnace manufacturer or
your HVAC contractor for assistance.
Heating system requires service or thermostat
requires replacement.
To diagnose this condition:
Press SYSTEM button to select HEAT and press
to raise the temperature setpoint above room
temperature. Within a few seconds the thermostat
should make a soft click sound. This sound usually
indicates the thermostat is operating properly. If
the thermostat does not click after being reset,
contact Delmarva Power Energy Wise Rewards for a
replacement thermostat. If the thermostat does click,
contact the furnace manufacturer or your HVAC
contractor for a service visit to verify the heating is
operating correctly.
Furnace (Air Conditioner) Cycles Too Fast or Too Slow (Narrow or Wide Temperature Swing)
Possible Cause Corrective Action
The location of the thermostat and/or the size of the
heating system may be influencing the cycle rate.
Electronic thermostats, like this one, normally
provide precise temperature control and may cycle
faster than some older mechanical models. A faster
cycle rate means the unit turns on and off more
frequently to maintain the desired temperature, but
runs for a shorter time so there is no increase in
overall energy use.

requires replacement.
To diagnose this condition:
Press SYSTEM button to select COOL and press
to lower the temperature setpoint below room
temperature. Within a few seconds the thermostat
should make a soft click sound. This sound usually
indicates the thermostat is operating properly.
If the thermostat does not click after being reset,
contact your installing contractor for a replacement
thermostat. If the thermostat clicks, contact the
furnace manufacturer or HVAC contractor for a
service visit to verify the cooling is operating correctly.
Multi-stage Air Conditioner/Heat Pump
Second, Third, and/or Fourth Stage Won’t Come On
Possible Cause Corrective Action
Your thermostat is designed to determine the
optimum time to activate the second stage. Simply
raising the temperature in heating or lowering it in
cooling will not always force the thermostat to bring
the second stage on quickly. There is a time delay
from 0–30 minutes depending on the performance
of the first stage of the system.
Wait for the second, third, and/or fourth stage to
come on.
