Setting Your Energy Saving Programs–Tips Before Starting
4.4
• It is important for you to set the current time of day (note the AM/PM indicator in the display), and
the current day of week correctly to avoid problems with program execution. This must be done
prior to entering any program settings.
• The heating and cooling programs have both separate setpoint times and setpoint temperatures.
• This thermostat is pre-programmed with weekday and weekend setpoint times and temperatures
recommended by the Environmental Protection Agency and the U.S. Department of Energy in
their ENERGY STAR® program. These settings provide efficient energy savings during normal
heating and cooling modes of operation. If you desire to use the setting in the table, no
further programming is necessary. Review these time and temperature settings prior to
establishing your personal program settings to maximize your savings, and minimize
programming requirements.
