Using multiple Nest thermostats in the same home

If you have more than one Google Nest thermostat in your home, they’ll work together to try to keep
you comfortable and help save energy.

If you have multiple thermostats in your home, you can replace any or all of them with a Nest
Thermostat. You won’t need to replace all of your current thermostats, they’ll keep
controlling your system just like they always have, you shouldn’t need to change any settings.

If you’re only going to replace one of your current thermostats with a Nest Thermostat, we
recommend that you replace the one in your main living area. That way it can see when
you’re home, learn what temperatures you prefer, and automatically help you save energy.

Your Nest Thermostats will learn separate schedules

Any Nest Thermostat that you add to your home will learn a personalized schedule for the
zone that it controls to keep you comfortable and help you save energy. Nest Thermostats
don’t share temperature schedules because they control the temperature for different parts
of your home. So you can teach your thermostat downstairs to warm up the kitchen in time
for breakfast, while the thermostat upstairs turns down for the day. Follow this link to learn
more about multiple thermostat zones in your home.

Home/Away Assist can help save energy

Home/Away Assist uses activity sensor information from your Nest products to tell when
you’re home or away. Home/Away Assist can switch all of the Nest Thermostats in your home
to Eco Temperatures when you’re away, and back to your regular heating or cooling schedule
when you return. If you kept some of your current thermostats, the Nest Thermostat can only
help you save energy in the zone that it controls.

You can also set Eco Temperatures manually on any of your Nest Thermostats to save energy
in one part of your home. Your other Nest Thermostats will continue to run your normal
schedule to keep you comfortable.
