Emerson Sensi UP500W Wi-Fi Smart Thermostat
Buttons and Icons
The Sensi Wi-Fi Programmable Thermostat can be operated through Wi-Fi using the Sensi app or it can be operated at the actual wall unit. Advanced features such as thermostat settings, scheduling and email alerts are only available through the Sensi app.
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 the 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”.
- Press “Exit”.

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.

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. |
| 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. |
| O/B | Changeover (reversing valve) connection for heat pump or zone panel systems |
| L | Heat Pump system, “L” wire connection. |
* 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 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.
