How does Auto-Schedule learn?
Nest starts learning your schedule right away. Here's how it works.
After Nest has been installed, it will default to a temperature of 68ºF/20ºC for heating and 75ºF/24ºC for cooling. Nest will hold these defaults until you change the temperature. The first day, Nest will hold the temperature you choose unless you change it, just like a regular manual thermostat.
After midnight, Nest will add the changes you made the first day to your schedule. So if you installed Nest at 5pm in the afternoon, turned the heat on to 70ºF/21ºC and then turned it down to 68ºF/20ºC before bed at 9pm, the next day Nest will change the temperature to 70ºF/21ºC at 5pm and 68ºF/20ºC at 9pm.
Any new changes you make will be added to the next day’s schedule. No matter what, when you change the temperature by turning the ring, Nest will keep that temperature until the next scheduled temperature change - or until you change it again.
After a few days, Nest will have learned your basic personal schedule. You’ll have taught Nest what temperatures you like when you wake up, when you go to work, when you relax around the house.
Note: To see or change the Nest learned schedule, go to SCHEDULE in the Nest menu. You can also change the schedule in the Nest apps.
Once Nest has learned your basic schedule, it will be less sensitive to each change that you make. Going forward, Nest will only learn from a pattern of at least two similar changes.
Examples of similar changes:
- Turn Nest to a similar temperature at about the same time two weekdays in a row (such as Monday and Tuesday) to learn a weekday change.
- Turn Nest to a similar temperature at about the same time on the same day two weeks in a row (such as two Mondays in a row) to learn a specific day change.
- Turn Nest to a similar temperature on both weekend days twice in a row (Saturday and Sunday) to learn a change for the weekend.
- Turn Nest to a similar temperature on a weekday and a weekend day (such as Friday and Saturday) and Nest will learn that change for all seven days.
Nest learns weekdays and weekend days differently, knowing that your schedule on Saturday or Sunday is likely to be different than your schedule during the week. Two or more similar changes on Saturday will only affect Saturdays, but make a similar change on Saturday and Sunday, and Nest will learn that this change applies to both weekend days.
To teach Nest to save energy, teach it good habits: turn it down before you go to bed, before you leave the house, or any time you would turn down a regular thermostat to save energy. The difference is, Nest will learn these changes and soon, you won't need to make them every day. You can see the results of teaching Nest good habits in the Energy History display.
