Increase your comfort and decrease your energy bill with the help of the Nest Learning Thermostat. This smart device learns how you like to heat your home, then intelligently figures out the most energy-efficient way to keep you comfy. Since it's WiFi-connected you can even change the thermostat over the internet from anywhere in the world.
Reduce your energy bill.
Did you know that your thermostat controls about half of your home's energy usage? That's right, the cost of heating or cooling your home is about as high as the energy costs of your computers, TVs, appliances, and lighting combined. Nest uses smart learning technology to save energy automatically, which reduces your utility bill. Your wallet will thank you.
Nest learns your schedule and heating/cooling preferences over time. It then takes this data and programs itself in a way that reduces overall energy usage up to 20%. Nest is smart enough to reduce the thermostat when you're away at work, and it displays the Leaf icon to show you when it's at a temperature that's saving you money.
Have you ever installed a lighting fixture on your own? Then you'll find it simple to install Nest, and probably in less than 30 minutes. If you'd rather let a professional handle it, you can contact a Nest Pro to install Nest, remove and recycle your old thermostat, and connect Nest to your WiFi network. Nest is designed to work with 95% of homes with low voltage systems so odds are that it'll fit nicely in your home.
Works with Nest.
Since Nest is smart and WiFi-connected, it's able to work with a variety of other smart devices to provide additional convenience and functionality, and the list of compatible devices is growing all the time. A smart garage door can tell Nest when you've left the house, a smart door lock can notify Nest about who's arrived home and what temperature they prefer, and smart appliances can go into energy saving mode when Nest tells them that you're away.
- Auto-schedule feature learns from your temperature preferences and programs itself in about a week
- Sets itself at a temperature that feels comfortable while saving energy so you can enjoy reduced energy bills (up to 20%)
- Figures out when you're away at work and reduces the thermostat accordingly to save energy
- Connects with your home's WiFi network so you can control it from your smartphone, tablet, or laptop from anywhere in the world
- WiFi connectivity allows Nest to link up with other smart devices and work together to create additional smart home convenience
- Airwave automatically reduces air conditioning usage when indoors humidity isn't too high, so you'll get reduced energy bills while keeping the house cool
- View Energy History on the Nest Mobile or Web apps so you can get detailed information about your energy usage and figure out how best to save
Nest works with over 95% of 24V heating and cooling systems, including gas, electric, oil, solar, hot water, geothermal, forced air, heat pump and radiant.
- Heating: one, two, and three stages (W1, W2, W3)
- Cooling: 1 and 2 Stages (Y1, Y2)
- Heat Pump: with auxiliary and emergency heat (O/B, AUX, E)
- Fan (G)
- Power (C, Rh, Rc)
- Whole home humidifier or dehumidifier (HUM, DEHUM)* - professional installation recommended
- Dual fuel systems (heat pump with furnace)* - professional installation recommended
- Common wire not required in 99% of installations
The Nest Learning Thermostat is not compatible with line voltage, millivolt systems or low voltage systems with incompatible wires. The Nest Thermostat is not compatible with some systems without a common wire installed.
The Nest Learning Thermostat is only compatible with low voltage 24 volt systems, not line voltage or millivolt systems. While most low voltage systems are compatible with the Nest Thermostat, here are some exceptions:
- Remote sensors. While the Nest Thermostat may be compatible with this system, it won't be able to gather data from existing remote sensors.
- Proprietary systems. Proprietary systems use a serial communications protocol to communicate between the system and the thermostat. The Nest Thermostat can't communicate with serial protocols, though some proprietary systems can be wired with standard HVAC wires.
- Some micro-controller based systems. Systems that use micro-controllers instead of relays are sometimes more sensitive to power sharing. If so, the Nest Thermostat may need a common wire to be compatible with these systems.
- High impedance systems. Some systems with particularly high impedance can't deliver enough power to the Nest Thermostat over the HVAC wires. If so, the Nest Thermostat will need a common wire to be compatible with these systems.
- Three stage cooling. The 2nd generation Nest Learning Thermostat is only compatible with systems that have one and two stage cooling.
- International systems. Some international systems, such as Buderus boilers, have dry contacts or other incompatible wiring. These systems may require relay panels in order to be installed with standard American thermostat wiring.
- Heat pumps with L wires. The Nest Thermostat doesn't support Service Indicator (L) wires.
Zone relay panels or control panels. Some systems have control panels or equipment interface modules that require a common wire to be compatible with the Nest Thermostat.
Here's a list of known panels that require a common wire:
- Honeywell AQ25110B
- Honeywell EMM-3
- Honeywell TZ-4
- Honeywell HZ311
- Bryant 548F036
- White-Rogers 36C03-300
- Carrier HK42FZ011
- Nordyne 624631-A
- Nordyne 903915A
- Waterfurnace ATV045A 110CIT
Some gas valves on systems vibrate or buzz when the Nest Thermostat is installed. This can usually be fixed by connecting a common wire.
