BASIC FUNCTIONALITY
Switching system mode
Press the mode button (see buttons and icons) to
switch between all available system mode settings.
When the mode is “Off” the thermostat will not
bring on your heating or cooling systems.
Fan mode
If you want to circulate the indoor blower, you can switch
fan mode to “On.” Turn the fan back to “Auto” when you want
the thermostat to control your indoor blower as necessary.
Leaving the fan in “On” will run your blower continuously.
Holding one temperature
If you want to hold one temperature, turn Schedule “Off.” Then,
adjust the set point using the up and down arrow buttons.
The thermostat will hold this temperature, in the set system
mode, until you turn Schedule back “On” or until you adjust
the set point again using the up and down arrow buttons.
Temporary hold
When your Schedule is “On,” your Sensi thermostat
controls your home based on the time and temperature
settings in the current schedule. To temporarily change
your temperature, use the up and down arrows in the app
or on the thermostat. Your Sensi thermostat will display
the time it will hold for next to the set temperature. It
will hold your new temperature until the next scheduled
set point with a minimum hold time of two hours.

INSTALLATION
Set up HVAC equipment
This allows you to change a series of settings to customize the thermostat for your specific
system. Refer to the chart below for a complete listing of thermostat configurations and what
they stand for. If you are installing the thermostat on the wall for the first time, we highly
recommend that you download the Sensi app and follow the installation instructions.
However, if you are experiencing an issue or you want to check your system configurations, you
can manually configure your thermostat as well. Learn more about how to properly configure your
thermostat by searching “configure” on our support site at sensi.emerson.com/en-us/support.

If the old thermostat has separate RC and RH wires coming out of the wall, clip the RC/
RH jumper on the back of the thermostat above the battery compartment.
*
*The common wire could be labeled “C” on your old thermostat, or it could be labeled “B”
or “X.” Please refer to the owner’s manual of your old thermostat for clarification.
Does Wire Color Correspond to the Thermostat
Terminals?
Wire color does not always correspond to the thermostat letters. A white wire may be attached to the “W” terminal
on the old thermostat, or it may be attached to a different terminal with a different letter. Be sure to take a photo
of the old thermostat that shows the wire colors and terminal letters before labeling and removing any wires.
