Learn about the Nest Thermostat temperature screen

<= Back

The Nest Thermostat’s temperature screen shows you the current temperature in your home and the target temperature that you’ve set. You’ll also see the Nest Leaf if you’ve selected an energy-saving temperature.

There are some differences between what you’ll see in the app and on your thermostat. You’ll see some extra options for system controls are well as the current humidity in your home.

On your thermostat:

– Whether your system is heating, cooling or idle (the app background is orange when heating, blue when cooling, and black when idle)

– The target temperature

– Fan (when it’s running)

-Time-to-Temperature

– Nest Leaf (depending on target temperature)

– Eco (when thermostat switches to Eco Temperatures)

Nest Learning Thermostat:

Nest Thermostat E:

In the app you’ll also see:

– System Mode (switch between HeatCoolHeat • CoolEco or Off modes)

– Fan (fan control if you have a forced air system)

– Schedule (for changing scheduled temperatures)

– History (to view your Energy History)

– The current humidity in your home

– Settings (change Eco Temperatures, set a fan schedule, lock the thermostat, and more)

What is Time-to-Temperature?

With Time-to-Temperature, the Nest Thermostat displays how long it will take for your home to reach the temperature you’ve chosen. This keeps you from being tempted to set the temperature too high (or too low) and waste energy while running your system unnecessarily.

Applies to: Nest Thermostat E, 3rd gen Nest Learning Thermostat, 2nd gen Nest Learning Thermostat,1st gen Nest Learning Thermostat

Use Time-to-Temperature to help you save energy. Cranking the heat up to 90ºF/32ºC won’t make your home heat up any faster, but it will waste energy if you don’t remember to turn it down. The longer your system is heating or cooling your home, the more energy you’re using. Just choose a comfortable target temperature and your Nest Thermostat will tell you how long it will take to get there.

Your Nest Thermostat starts learning as soon as you install it. When you change the temperature, you’ll see the estimated time it will take to reach the new target temperature. Your thermostat will learn how quickly your home warms up and cools down and improve its estimates as you continue to use it. However, your thermostat will only estimate Time-to-Temperature for temperatures that you’ve manually set on the thermostat itself or with the Nest app. Temperatures that you have put into your schedule and temperatures added by Auto-Schedule won’t have a Time-to-Temperature displayed. Once the target temperature is reached, the Time-to-Temperature will disappear, and the screen background will turn from orange (heating) or blue (cooling) to black.

The Nest Thermostat estimates Time-to-Temperature in increments of five minutes. If it’s less than ten minutes until the temperature you’ve selected is reached, the display will read, “less than ten minutes.” If it’s more than two hours, Nest will read “IN 2+ HR.”

Why don’t I see Time-to-Temperature?

The Nest Thermostat won’t display a time estimate if continuous heating or cooling is needed to maintain the temperature that you have selected or if the temperature fluctuates unexpectedly. For example, if you have a poorly insulated home and an extreme cold front rolls in, your heating system might have to constantly cycle to keep the temperature up. In this case, the display will simply read “HEATING” without a time.

When the seasons change and you switch your Nest Thermostat between heating and cooling for the first time, it will need to learn to estimate Time-to-Temperature for the new system, so you won’t see the time estimate on the thermostat screen for the first few days. However, the next time the seasons change, your thermostat will remember what it has already learned.

Learn about the Nest Leaf on your thermostat:

The Nest Leaf guides you to personalized energy savings for your home.

The Nest Leaf  icon appears on the thermostat display or in the Nest app when you choose an energy-saving temperature. When you follow the Leaf, you know you’re saving energy.

The Leaf will appear the first day you install your Nest thermostat. During the first few days, the Leaf is based on set temperatures. After that, Nest will personalize the Leaf to your home and schedule.

– When heating, setting Nest to 62°F/16.5°C or below will always get the Leaf.

– When cooling, setting Nest to 84°F/29°C or above will always get the Leaf.

– The temperatures that merit the Leaf will depend on your temperature preferences. These temperatures will also change over time as your Nest thermostat continues to learn and as you save energy.

If you have multiple Nest thermostats in your home, you’ll get the Leaf at different temperatures on different thermostats. This is because your schedule and the temperature changes that you make are a bit different for each thermostat.

What are Eco Temperatures?

Your Nest thermostat can automatically switch to Eco Temperatures after it senses that nobody’s home to help save energy. You can also manually set your thermostat to Eco Temperatures anytime, even when you’re home. You’ll know Eco Temperatures are active when you see Eco on your thermostat and in the Nest app.

When you first install and setup your Nest thermostat, you’ll also decide what temperatures your system will maintain when your thermostat is manually or automatically set to Eco temperatures.

How Eco Temperatures affect your system behavior:

When your thermostat is set to Eco, your system may still turn on in some cases:

– If your home’s temperature gets higher than the Cool to temperature you’ve set, your thermostat will turn on cooling until your home cools to the Eco Temperature you set.

– If your home’s temperature gets lower than the Heat to temperature you’ve set, your thermostat will turn on heating until your home warms to the Eco Temperature you set.

– Your thermostat won’t follow its usual temperature schedule when it’s set to Eco since it’s trying to help save energy.

Controlling your fan with the Nest Thermostat:

How to turn your fan on right away:

– Press your thermostat ring to open the Quick View menu.

– Select the Fan  icon.

– Turn the ring to select how long you’d like your fan to run. If you have a multi-speed fan, you’ll be able to select your fan speed.

– You’ll see a spinning fan icon on your thermostat’s screen while it’s running.

– Your fan will turn off automatically after the time you’ve selected, or you can turn it off early by selecting Stop now from the fan menu.

How to set a daily fan schedule:

– Press your thermostat ring to open the Quick View menu.

– Select Settings 

– Select Fan Schedule.

– Choose how long you’d like your fan to run per hour, or set it to always run.

– Select what hours of the day you’d like your fan to run. If you have a multi-speed fan, you can select a fan speed for your fan schedule.

– Select Done to set your schedule.

Your fan will turn on automatically each day for the time and duration you’ve selected. You can always edit or disable your schedule at any time from the fan menu.

How to set your system’s fan speed:

This option is only available on systems with multi-speed fans.

– Press your thermostat ring to open the Quick View menu.

– Select the Fan  icon.

– Choose System fan speed.

– Select the fan speed you’d like to use when your system is heating or cooling your home. You can choose LowMediumHigh or Auto, depending on your system’s wiring.

– Choose Done to set your system’s fan speed.

If you choose low, medium, or high, your fan will always run at that speed when heating or cooling your home. If you choose Auto, your Nest Thermostat will automatically choose how fast to run your fan when heating or cooling your home.

You’ll still be able to choose a different speed for your schedule and each time you choose run your fan. For example, you can set your fan to high when heating or cooling and and schedule your fan to run at low speed in the morning to circulate the air in your home.

Reading your Nest Thermostats Energy History:

Your Nest thermostat’s Energy History shows you how often and for how long your system has run, so that you can make smart choices about your schedule and temperature preferences.

Your Energy History is a detailed summary that covers the last 10 days. You can view it with the Nest app on a phone, tablet, or computer.

Note: To see Energy History, your thermostat must be connected to Wi-Fi and added to your account in the Nest app.

Viewing Energy History on your thermostat:

You can find your Energy History by selecting Energy in the Nest thermostat’s Quick View menu.

If you’re using a Nest Thermostat E, your Energy option will be in the Settings  menu.

Your Energy History at a glance:

When you first select Energy, you’ll see a simple graphic that represents how long your system ran for the day. An orange bar represents heating, and a blue one represents cooling (if available). If your thermostat was in HEAT • COOL mode (if available), or you recently switched between modes, you’ll see both orange and blue bars.

Turn the thermostat’s ring to see the Energy History for other days. You can look as far back as 10 days ago. Since the Nest thermostat needs time to learn about how you use energy, it will usually take at least a day after installation for information to appear.

Daily Energy History details:

Press the thermostat’s ring to see more details about a particular day. Turn the ring to scroll down and to see more information, like if your energy use was significantly higher or lower than the average over the last week. If it was, the thermostat will also show you the main contributor: your adjustments, Home/Away Assist, or the weather.

Press the thermostat ring to go back to the main Energy History screen when you’re done, or hold down the ring to exit and return to the thermostat temperature screen.

Energy History and Time of Savings:

If you’ve signed up for Time of Savings, you’ll see some additional information in your Energy History. A green bar underneath the blue cooling or orange heating bars shows times of the day when electricity costs were higher than normal. The lighter, more intense the green, the higher costs were during that time. You can quickly compare when your system was running and when electricity was more expensive.
