to give the furnace a head start to heat the house before you arrive home. (Again, this is higher heating or lower for cooling.) SLEEP is the time period you can set for an energy-saving temperature while you are sleeping. (Again, this is lower for heating or higher for cooling. For more comfortable sleeping, some people choose not to raise the cool temperature during the night.) You will set one schedule for weekdays and another for weekends, because your requirements will probably be different for each. Also, during weekends, only the WAKE and SLEEP time periods are available. Fill in the times and temperatures you desire for weekdays and weekends. If you decide not to program the thermostat, it will automatically control heating at 68°F (20°C), and cooling at 78°F (26°C), 24 hours a day. Also, you do not need to enter a time and temperature program for all periods if your schedule does not require it. For example, a house that is occupied during weekdays would only require programs for WAKE and SLEEP. If no program is entered for the weekends, the thermostat will operate on the weekday SLEEP program all weekend. Before programming, remove the clear plastic overlay covering the display. When pressing the keys, use the ball of your finger or a soft pencil eraser. Using sharp fingernails or pencil points can damage the keypad. If you make an error at any time during programming, just press the RUN PROGRAM key, and continue again at the step where you left off. 11 69-1012
