List of Nest Thermostat Symbols & Their Meanings

Swirl symbol

The swirl symbol on a Nest thermostat indicates Nest airwave. Nest Airwave is a feature available on certain Nest thermostats that optimizes cooling efficiency by using the remaining cool air in your home’s HVAC system.

 It works by temporarily shutting off the compressor while the fan continues to circulate the cool air, reducing energy usage and increasing energy savings without sacrificing comfort. 

This feature is particularly effective in humid climates where it can help maintain a comfortable temperature while reducing the need for excessive cooling.

Yellow leaf symbol

The Nest Leaf symbol appears on the thermostat and in the Nest app to indicate when the thermostat is set to an energy-saving temperature. 

Initially, it may appear based on preset temperature recommendations, but over time, as the Nest thermostat learns your habits and preferences, it will optimize its energy-saving suggestions and the Leaf will appear when it knows your usage is at its most efficient levels. 

It’s a helpful reminder to conserve energy and save money.
