Nest Learning Thermostat 2nd Generation with Base Plate, Electrical Box Bracket and Trim Kit. Condition is Used, in good condition, still works and fully functional!

The Nest Learning Thermostat automates its energy-saving programs within approximately one week, optimizing heating and cooling costs.

It meticulously creates a personalized schedule based on temperature adjustments made by users, continuously adapting to their evolving lifestyle.

The Nest Thermostat monitors the absence of occupants and automatically adjusts the temperature to prevent unnecessary heating or cooling of empty homes.

The Nest Leaf illuminates when the temperature is set to an energy-efficient level, providing guidance to users in making appropriate adjustments.

Users can conveniently adjust temperatures from anywhere using their smartphones, tablets, or laptops. Additionally, they can modify their schedules and access their Energy History.

The Airwave feature automatically activates and reduces AC costs while maintaining a comfortable indoor temperature when humidity levels permit.

Installation is straightforward with the provided guide and accessible instructional videos.

The Energy History feature enables users to precisely track system activity, while the Nest Energy Report provides a comprehensive monthly summary of energy usage. Enhanced knowledge leads to increased savings potential.

System Match automatically activates specific energy-saving or comfort features tailored to the user’s heating or cooling system.

The Thermostat ensures that desired temperatures are maintained at the specified times. For instance, if the schedule indicates 72°F at 6 a.m., Early-On will initiate heating or cooling early to achieve the desired temperature by the time the alarm rings.

Nest reminds users to replace their air filters based on the duration of heating or cooling operations. A clean filter can significantly reduce heating or cooling expenses by up to 5%.

Heat Pump Balance is particularly beneficial for homes equipped with heat pumps, minimizing the frequency of unnecessary use of expensive auxiliary heat. Users can choose between prioritizing comfort or savings, and Heat Pump Balance will automatically adjust accordingly when auxiliary heat is activated.

True Radiant for radiators and underfloor radiant systems provides a predictable schedule and consistent heat, eliminating the need for guesswork regarding optimal temperature settings.

Most individuals install the Nest Thermostat independently within 30 minutes or less. Once installed on the wall, it automatically activates the most suitable features for your system and commences learning about you and your home. By instructing Nest to save energy, you can optimize your heating and cooling expenses. While programming a thermostat may seem intricate and time-consuming, an un-programmed thermostat can result in a 20% reduction in heating and cooling costs. Consequently, the Nest Thermostat automates this process. Simply adjust the temperature settings, and the Nest Thermostat will learn your preferences and establish a personalized schedule. By teaching it efficient temperatures for a few days, you can expect the thermostat to automatically adjust the settings within a week. This feature allows you to save energy while you are away from home.

With Auto-Away™, the Nest Thermostat automatically adjusts to an energy-efficient Away temperature when you depart. This feature is compatible with 90% of homes, even if your Nest Thermostat is positioned in a location that you do not pass on your way out the door. Additionally, the Nest app enables you to connect to your thermostat from a mobile device, allowing you to adjust the temperature remotely, even before you arrive home.

The Nest Learning Thermostat is compatible with 95% of 24V heating and cooling systems, including gas, electric, forced air, heat pump, radiant, oil, hot water, solar, and geothermal systems. This compatibility is based on data gathered through the Nest’s online compatibility tool.

Heating: 1, 2, and 3 stages (W1, W2, W3)
