Nest Protect

It’s time to expect more from your smoke alarm.

The new Nest Protect has been redesigned from the inside out. It has an industrial-grade smoke sensor, tests itself automatically and lasts up to a decade. It’s also the first home alarm you can silence from your phone without any extra hardware required. And just like the original Nest Protect, it tells you what’s wrong and can even alert your phone.

Did you know…

In the 1970s, it would take about 30 minutes for a fire to take over a room. Today, it can take less than 5.

Tests itself: You’re supposed to test smoke alarms monthly. But most people don’t. So Nest Protect checks its batteries and sensors over 400 times a day. And it’s the first alarm that uses Sound Check to quietly test its speaker and siren once a month.

Q: How does the Nest Learning Thermostat learn?
— Asked by a customer on 23rd November 2017
A: Nest uses Nest Sense (a combination of algorithms and temperature, humidity and activity sensors) to learn schedules and to customize energy saving features for your home. During the first week or so, each manual temperature change will contribute to Nest’s schedule. After that, Nest will only learn from patterns of similar changes. Throughout the first week, Nest’s energy saving features (Eco temperature, Time to Temperature, and the Nest Leaf) will appear.
Q: How does Nest Learning Thermostat control hot water?
— Asked by a customer on 23rd November 2017
A: The Nest Thermostat allows you to set a hot water schedule. It also takes advantage of energy-saving features like Eco temperature. If you need to make adjustments, you can change your hot water schedule or activate boost mode.
Q: What are Safety Temperatures and how do they work?
— Asked by a customer on 25th November 2017
A: If the room temperature drops below the set Safety Temperature, your Nest Thermostat will automatically start heating. It will also send a notification in your Nest app. Once the room temperatures return to normal, you'll receive another notification.
Q: How does Bacteria Prevention work?
— Asked by a customer on 25th November 2017

Q: Which systems are compatible with the Nest Learning Thermostat?

Q: Can I use the Nest Learning Thermostat without Wi-Fi?
— Asked by a customer on 25th November 2017
A: All of Nest's core learning and energy saving features works without Wi-Fi, although certain features—like remote control, weather, and automatic software updates—do require Wi-Fi.
Q: Does the Nest Learning Thermostat work with zoned systems?
— Asked by a customer on 25th November 2017
A: Yes, Nest supports zoned systems. Each zone will need its own Nest Thermostat and Heat Link. Each Heat Link will connect each zone valve, either directly or via a junction box. If you have multiple zones, you can replace all of your old thermostats with Nest Thermostats or you can replace just one to try it out.
Q: Is Farsight available on previous versions of the Nest Learning Thermostat?
— Asked by a customer on 25th November 2017
