How does Auto-Schedule learn?

The Nest Learning Thermostat starts learning your schedule right away. Here's how it works.

After your Nest Learning Thermostat has been installed, it will default to a temperature of 20ºC for heating. The Nest Thermostat will hold this default until you change the temperature. The first day, the Nest Thermostat will hold the temperature you choose unless you change it, just like a regular manual thermostat.

After midnight, the Nest Thermostat will add the changes you made the first day to your schedule. So if you installed your Nest Thermostat at 5pm, turned the heat on to 21ºC and then turned it down to 20ºC before bed at 9pm, the next day your Nest Thermostat will change the temperature to 21ºC at 5pm and 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, your Nest Thermostat will keep that temperature until the next scheduled temperature change - or until you change it again.

After a few days, the Nest Thermostat will have learned your basic personal schedule. You’ll have taught the Nest Thermostat 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 Thermostat learned schedule, go to SCHEDULE in the Nest Thermostat menu. You can also change the schedule in the Nest app or on the Web.

Once the Nest Thermostat has learned your basic schedule, it will be less sensitive to each change that you make. Going forward, your Nest Thermostat will only learn from a pattern of at least two similar changes.

Examples of similar changes:

  • Turn the Nest Thermostat 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 the Nest Thermostat 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 the Nest Thermostat to a similar temperature on both weekend days twice in a row (Saturday and Sunday) to learn a change for the weekend.
  • Turn the Nest Thermostat to a similar temperature on a weekday and a weekend day (such as Friday and Saturday) and your Nest Thermostat will learn that change for all seven days.

The Nest Thermostat 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 your Nest Thermostat will learn that this change applies to both weekend days.

To teach your Nest Thermostat 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, the Nest Learning Thermostat will learn these changes and soon, you won't need to make them every day. You can see the results of teaching your Nest Thermostat good habits in the Energy History display.
