Note: A good rule of thumb is to adjust this about 5 to 8°F (3 to 5 °C) lower during cycles when you are away to help reduce energy use. If you set the “away” cycles too low, it will take much longer to raise the temperature again and may result in unsatisfying performance.

Note: The display in normal operating mode will not show a “U1” indicating “User” schedule. Also, all schedule adjustments are saved in memory and will not be lost during power failure.
Note: If you only want to use two cycles during a day, clear the other cycles by reducing their temperature below 40°F (4.5°C) to show (---). To use these cycles again, adjust their time and temperature.
