Select LEAVE if you want an energy-saving temperature while you are away at work or school. (This will be a lower temperature during heating season, or a higher temperature during cooling season.) Select RETURN if you want the house at a comfortable temperature for activities before bedtime. When deciding what time to set for your RETURN period, include extra lead time, depending on the outside temperature and your furnace response time, to give the furnace a head start to heat the house before you arrive home. (Again, higher for heating or lower for cooling.) Select SLEEP if you want an energy-saving temperature while you are sleeping. (For more comfortable sleeping, some people choose not to raise the cool temperature during the night.) Fill in the times and temperatures you desire for weekdays and weekends. If you decide not to program the thermostat, it automatically controls 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 not require programs for LEAVE and RETURN. When pressing the keys, use the ball of your finger or a soft pencil eraser. NOTE: 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 last step. 5 69-0812-2
