For the Nest Thermostat, you can use the Eco preset to quickly adjust to energy-saving temperatures manually or in its temperature schedule.
Your system will either heat or cool to try to keep your home within the Eco Temperatures range.Your system will not turn on to meet any scheduled temperatures, and you won’t be able to manually change the temperature until you switch your thermostat to another mode.All other heating, cooling, and fan control are disabled. When your thermostat is set to Off, it will only heat or cool to try to maintain your Safety Temperatures.For example, you may need this mode if you live in a desert climate and require cooling during the day and heating at night. This mode is useful for climates that consistently require both heating and cooling on the same day.Your thermostat will automatically switch your system between heating and cooling as needed to meet any scheduled temperatures or a temperature that you’ve manually selected.Your system will either heat or cool to try to keep your home within the temperature range you’ve manually set.Your thermostat will start cooling to try to maintain any scheduled temperatures or a temperature that you’ve manually selected.It won’t start heating unless your Safety Temperatures are reached.
