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.

Delmarva Power Energy Wise Rewards Thermostat User’s Manual 11
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.

Furnace Lock-Out Condition. Heat may also be intermittent.
Heating system requires service or thermostat requires replacement.
Furnace (Air Conditioner) Cycles Too Fast or Too Slow (Narrow or Wide Temperature Swing)
Possible Cause Corrective Action
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.
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.
The location of the thermostat and/or the size of the heating system may be influencing the cycle rate.
14 Delmarva Power Energy Wise Rewards Thermostat User’s Manual
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.
Troubleshooting
No Cool
Possible Cause Corrective Action
System switch not set to COOL.
Outdoor unit disconnect or breaker tripped. Verify the outdoor unit disconnect or breaker has not

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.
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.
Delmarva Power Energy Wise Rewards Thermostat User’s Manual 15
Wait for the second, third, and/or fourth stage to come on.
