On a Nest thermostat, blue indicates that the system is cooling. This is a standard color code used in many HVAC systems, where blue signifies a cooling mode.
Here's a more detailed breakdown of what blue might indicate on your Nest:
- Blue ring: If you see a blue ring around the Nest thermostat's display, it means the system is actively cooling your home.
- Blue icon: Some Nest models use a blue icon to represent cooling. This icon might be a snowflake, a fan with a snowflake, or a stylized air conditioner.
- Blue text: The Nest thermostat's display may also show "Cooling" or "Cool" in blue text when the system is actively cooling.
Remember, the specific way blue is displayed on your Nest thermostat might vary slightly depending on your model.
