Step 2: Main Menu and Thermostat Settings
C. Description of Menu Options
The following are detailed descriptions of your Energy Wise Rewards thermostat configuration menu options.
1. Programming – Heat/Cool Programming
Your Energy Wise Rewards thermostat can program the Heating and Cooling schedules as Individual Days or
Weekdays/Weekends. Using the Individual Days programming profile, you can program each day of the week with
its own setpoint profile. With a Weekdays/Weekends profile, Monday–Friday has the same setpoint profile while
Saturday–Sunday can be programmed with its own setpoint profile.
2. Thermostat 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. Thermostat Settings – Temperature Limits
Temperature limits can be used to limit 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
• Heat Setpoint – 99°F
4. Thermostat 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 screen; your desired offset will be displayed on the right side of the screen.
Options for this menu item include:
• +1° through +5° – Adjusts the displayed temperature a specified number of degrees higher than the measured
room temperature
• 0 – (Default) Displays the measured room temperature
• –1° through –5° – Adjusts the displayed temperature a specified number of degrees lower than the measured
room temperature
