The Boost feature is available only if your HVAC equipment has more than one stage of heating or cooling. The Boost feature provides maximum heating or cooling when you need it. You can activate it by a rapid 3-degree manual adjustment of your temperature set point.

Turing Boost on provides maximum comfort. Turning Boost off provides maximum efficiency.

How does the Boost feature work?

When the Boost feature is turned on, all available heating or cooling stages will be utilized when the temperature is manually changed by three degrees—a three-degree increase in heat mode, or a three-degree decrease in cool mode.

When the Boost setting is turned off, the thermostat will utilize additional stages based on a calculation of current system performance.

The Boost feature is defaulted to on to provide comfort rapidly when the temperature is adjusted three or more degrees in the corresponding mode.

Where is the Boost feature located?

For systems with multiple indoor or multiple outdoor stages of heating or cooling, the Boost feature will appear in the Sensi app.

  1. Open the Sensi app and select the correct thermostat from the dashboard screen
  2. (iOS users) Navigate to Settings by selecting the gear icon at the top right of the screen. (Android users) Navigate to Settings by selecting the three-dot menu button at the top right of the screen
  3. Select System settings
  4. The Boost feature can be turned “on” or “off” from this screen
