What happens if I don't program the thermostat?
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. Additionally, if no program is entered for the weekends, the thermostat will operate on the weekday SLEEP program all weekend. (Page 11)
