Operation

How do I use Auto Mode manually at the thermostat?


Sensi thermostat has a feature called Auto Mode, which allows the thermostat to switch from Heat to Cool, or Cool to Heat automatically. Auto Mode can only be enabled from the Sensi app.

  • From the main screen of the app, tap the Mode icon in the lower left corner. All available options will be displayed.
  • Select “Auto” to allow the thermostat to switch between heating and cooling based on room temperature and the selected heating and cooling set points.


“Auto Mode” will be displayed on the Sensi thermostat when the Auto Mode feature is on. To adjust, follow the steps below:


  • When heating is activated in Auto Mode, “Auto Mode” displays on the thermostat screen to the left of the Room Temperature and the thermostat will show Heat Mode. To adjust the heat set point, press the “Up” or “Down” arrows on the thermostat.
  • To adjust the cool set point when heating is activated in Auto Mode:
  • Press and hold the “Up” and “Down” arrows at the same time until the Cool Mode indicator begins flashing on your Sensi thermostat.
  • Adjust the desired cool set point.
  • After ten seconds of inactivity, the Cool Mode indicator will stop flashing and the thermostat will return to Heat Mode. Changes made to the cooling setpoint will be saved.
  • When cooling is activated in Auto Mode, “Auto Mode” displays on the thermostat screen to the left of the Room Temperature and the thermostat will show Cool Mode at the bottom left of the screen. To adjust the cool set point, press the “Up” or “Down” arrows on the thermostat.
  • To adjust the heat set point when cooling is activated in Auto Mode:
  • Press and hold the “Up” and “Down” arrows at the same time until the Heat Mode indicator begins flashing on your Sensi thermostat.
  • Adjust the desired heat set point.
  • After ten seconds of inactivity, the Heat Mode indicator will stop flashing and the thermostat will return to Cool Mode. Changes made to the heating set point will be saved.


Auto Mode allows heat to come on when the room temperature drops below the heat set point, and cool to come on when the room temperature rises above the cool set point. Your Sensi thermostat will always maintain a minimum separation of two degrees between the heat and cool set points to prevent heating and cooling from running at the same time. To prevent set points from overlapping, adjusting the heating set point higher can move the cooling set point higher. Similarly, adjusting the cooling set point lower can move the heating set point lower.


NOTE: Changing the mode indicator to Heat, Cool, Aux or Off at the thermostat will disable Auto Mode. To turn Auto Mode back on, use the Sensi app.
