What’s in the box?

• Sensi Thermostat
• Screws and Anchors
• Wire Labels

Items needed for Wi-Fi connection:

• The homeowners compatible iOS or Android device with the Sensi app installed and registered
• Your customer’s Wi-Fi network name (SSID) and password
• A Wi-Fi network with 802.11n 2.4GHz band

QUICK TIP: Ask the homeowner to download the Sensi app and gather their Wi-Fi information while you are installing the thermostat.

Installation

1. Turn terminal light switch on for better visibility.
2. Install Sensi thermostat, referring to these terminal definitions, cross references and wiring diagrams as needed:

† Two transformer systems (separate RC and RH wires), clip jumper located on backplate to the right of the terminals.

†† Label “B” as “C” only if the old thermostat also had a wire in “O”. If there is no wire on “O”-label the wire “B”.

††† On Heat Pump system with separate W2 and E wires, label both wires W/E (2 wires in one terminal).

SINGLE STAGE OR MULTI-STAGE SYSTEM (NO HEAT PUMP) WITH TWO TRANSFORMERS

† Two transformers systems (separate RC and RH wires), clip internal RC/RH jumper, located on back of thermostat.

HEAT PUMP SYSTEMS

† Internal jumper between RC and RH, located on back of thermostat.

†† Common connection required on Heat-only, Cool-only or Heat Pump systems.

Configuration

1. Before configuring the thermostat, switch off the terminal light.

2. Configure the thermostat to the appropriate system type. Press “Menu” on the thermostat and refer to these menu options as needed:
   

3. Once the thermostat is installed and properly configured, test the equipment by following these steps:

   • Turn on power to the system.
   • Fan Operation
   • If your system does not have a “G” terminal connection, skip to “Heating System” below.
   • Press the “Fan” button on the thermostat and select the “On” position. The blower should begin to operate.
   • Press the “Mode” button to turn off the system. Then press the “Fan” button on the thermostat and select the “Auto” position. The blower should stop immediately.
   • Circulating Fan
   • Press the “Menu” button on the thermostat and select “Advanced Setup” then select “Fan Mode Options”
   • Press “On” to enable circulating fan and set the % run time from 10%-100% in 5% increments (default is OFF).
   • The % run time is the percentage of time the fan shall run in a day. This calculation takes into account the amount of time the heating, cooling and continuous fan have run during the same day.
   • Heating System
   • Press the “Mode” button on the thermostat and select the “Heat” position.
   • Press the up arrow on the thermostat and adjust the setting to 1° above the current room temperature. The heating system should begin to operate and the thermostat display will turn red indicating heating on the screen.
   • For heat pumps with auxiliary, press the up arrow on the thermostat and adjust the setting to 3° above the current room temperature. The auxiliary heat should begin to operate and the thermostat will indicate “Heating Auxiliary” on the screen.
   • Press the down arrow on the thermostat and adjust the setting to 1° below the current room temperature. The heating system should stop operating and the display will go back to a neutral gray color.
   • Auxiliary System (only for heat pumps with auxiliary)
   • Press the “Mode” button on the thermostat and select the “Aux” position. This bypasses the heat pump and runs auxiliary-only heat.
   • Press the up arrow on the thermostat and adjust the setting to 1° above the current room temperature. The auxiliary heating system should begin to operate and the thermostat will indicate “Heating Auxiliary” on the screen.
   • Press the down arrow on the thermostat and adjust the setting to 1° below the current room temperature. The auxiliary heating system should stop operating and “Heating Auxiliary” will disappear from the screen.
   • Cooling System
   • Press the “Mode” button on the thermostat and select the “Cool” position.
   • Press the down arrow and adjust the setting to 1° below the current room temperature. The blower should come on immediately on high speed, followed by cold air circulation. The thermostat display will turn blue. Note that there can be up to a 5 minute delay for this process. This is indicated by a flashing setpoint temperature.
   • Press the up arrow and adjust the setting to 1° above the current room temperature. The cooling system should stop operating and the display will go to a neutral gray color.
   • If you encounter any issues while testing the equipment, refer to the troubleshooting actions on page 16.
   • Humidification
   • Press the “Mode” button on the thermostat and select the “Heat” position.
   • Press the up arrow on the thermostat and adjust the setting to 1° above the current room temperature. The heating system should begin to operate and the thermostat display will turn red indicating heating on the screen.
   • Press “Menu”, “Advanced Setup”, “Humidify”
   • Set Humidification to ON and set the humidity set point higher than the current room humidity.
   • Humidity can be adjusted from 5% to 50% in 5% increments.
   • Check that the humidifier is running.
   • Go back to the main screen.
   • Press the down arrow on the thermostat and adjust the setting to 1° below the current room temperature. The heating and humidification system should stop operating and the display will go back to a neutral gray color.
   • Dehumidification
   • Press the “Mode” button on the thermostat and select the “Cool” position.
   • Press the down arrow and adjust the setting to 1° below the current room temperature. The blower should come on immediately on high speed, followed by cold air circulation. The thermostat display will turn blue. Note that there can be up to a 5 minute delay for this process. This is indicated by a flashing setpoint temperature.
   • Press “Menu”, “Advanced Setup”, “Dehumidify”
   • Set Dehumidification to ON and set the humidity set point lower than the current room humidity. Humidity can be adjusted from 40% to 95% in 5% increments.
   • Depending on installed equipment, check that the system fan speed has slowed, the dehumidifier is running, or the system cools up to 3° below temperature set point or until the humidity set point is reached.
   • Go back to the home screen.
   • Press the up arrow and adjust the setting to 1° above the current room temperature. The cooling system should stop operating and the display will go to a neutral gray color.
