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
setpoint 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.
Circulating Fan
If you want to circulate the air in your home using your indoor blower fan,
you can set \this feature in the app or at the thermostat. A percentage is
selected to dictate how often the fan should run each hour, You can set 5%
increments from 10% – 100%.
EXAMPLE : If you set the Circulating Fan to 50%, the fan will un 30
minutes every hour. If any heat/cool cycles occur during the hour, their
runtime is subtracted from the overall fan run time.
Setting the feature from the thermostat:
1. Press “Menu”
2. Press “Next” until you come to “Fn Setup”.
3. Use the up arrow button to toggle the percentage you’d like the fan to run
each hour.

MENU CONFIGURATIONS
Pressing “Menu” at the thermostat 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.

WIRING TERMINALS
See below for definitions of the wiring terminals on the sub-base of the
thermostat.
Terminal outputs and wiring diagrams
| TERMINAL LABEL | DEFINITION |
|---|---|
| RH* | Power for heating, 24V |
| RC* | Power for cooling, 24V |
| C** | Common wire, 24V |
| G | Indoor blower (fan) |
| Y | First outdoor stage cooling on conventional systems or first heat and cool |
on heat pump systems
Y2/*| Second outdoor stage cooling on conventional systems or second heat and
cool on two stage heat pump systems or humidifier
W/E| First indoor stage heat on conventional systems or first stage
auxiliary/emergency heat on heat pump systems
W2/*| Second indoor stage heat on conventional systems or second stage
auxiliary/
emergency heat on heat pump systems or dehumidifier
O/B| Changeover (reverse valve) connection for heat pump or zone panel systems

- 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.

FAQS
If the power goes out, will this thermostat continue with my settings when power is restored? Or will I have to reprogram it?
It’ll retain the settings
does display stay light when heating or cooling ? Or do we have to touch it to see if it is working ?
It changes from color when heat is engaged. Almost an orange color. The actual brightness does not change unless you physically touch it.
Can this be used with zoned systems?
one each zone
If the power goes out, is there a battery back up that allows you to control the heat manually?
There is no physical battery backup, but since it’s connected to the internet,
your settings are saved. And you can pretty
much do anything off your phone with the app. If the power goes out, your hvac
probably won’t work anyway.
Will this thermostat work with a two stage AC system?
According to the documentation yes, “Conventional 2H/2C”. I’m not utilizing it with that type of application.
What is the max temperature this can be set at? Our current one only goes up to 90. We would like it to only cool if over 95.
Yes… the UPPER value goes to 99 degrees.
Why is the thermostat beeping?
The thermostat may beep when you first turn it on. This is normal. If the thermostat continues to beep, turn the power off and then back on. If this does not stop the beeping, contact Customer Support at 1-866-972-8378.
How do I change the batteries in my Sensi Smart Thermostat?
To change the batteries in your thermostat, remove the faceplate to access the battery compartment. Remove the old batteries and replace with two new AA Alkaline batteries. Make sure that the positive (+) side of the battery is facing up. Replace the faceplate and turn your thermostat back on to continue using it.
What are my Wi-Fi network credentials?
Your Wi-Fi network credentials are printed on a sticker located inside your Sensi Smart Thermostat’s battery compartment.
Does this thermostat allow differential temperatures greater than 1°?
The Sensi Touch Smart Thermostat allows for a temperature offset of +/- 5 degrees.
is there a swing settings?
Yes, though they call it “cycle rate” and not “swing” and the setting is FAST, MEDIUM, or SLOW. You can set a separate “cycle rate” for heat and cool.
Does this unit work with 5 ghz internet?
The sensi touch is only 2.4 ghz
Does this thermostat have Heat, Cool, and Auto, modes?
Yes
Why is the white color version insanely more expensive?
The black and silver version are probably discounted due to being less popular. There may be a lot of them sitting on shelves not moving.
Does this thermostat (or any others ) keep a runtime of the unit? I would like to see how many times and duration of when the heat pump comes on.
Yes. Mine has a usage tab. It will tell you by day for the last week and by month. Runtime of ac, fan only, or heat.

how easy this to program (not install) from the touch screen panel without using the app?
Easier to program through touch screen than though app, but app is not difficult.
Does the thermostat come with a mounting plate?
The mounting plate is included but does not cover anything larger than the size of the thermostat. amazon does sell a larger size back plate to cover extra holes or missing paint not included with this stat.

Does it work with baseboard heater?
If you are talking about electric baseboard heat (110v or 220V), no. If it’s hot water baseboard heat from a boiler system, then most likely it would work (that’s what I have, along with a separate A/C system, and it works great).
