Basic Functionality

SWITCHING SYSTEM MODE

Press the “Mode” button 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 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 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 set to “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 “Temporarily Set To” on the thermostat and will hold your new

temperature until the next scheduled set point with a minimum hold time of two hours.

TURN WI-FI OFF

If connecting to Wi-Fi is not an option, you can turn off Wi-Fi on the

thermostat and manually set a time and a schedule from the wall unit.

To turn off Wi-Fi:

Press “Menu”.

Press “Next” ﬁve times to go to the “Wireless (Setup)” screen.

“On” should be ﬂashing at the top.

Use the up and down arrow buttons to change it to “Off”.

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.
