Downloading the Sensi App

DOWNLOAD THE SENSI APP

The Sensi thermostat is a Wi-Fi
enabled device.

To install and configure your thermostat
correctly, you must use the Sensi app. To
start the installation process, download the
Sensi app to your smart phone or tablet. It
is a free download. The Sensi app requires
the following Operating System (OS)
software to download:

• Android (Google Play) version

4.0 or later

• iOS (Apple) version 6.0 or later

*Note that in the iOS store, the Sensi App will ONLY appear on an “iPhone only”
search. On an iPad, this will have to be changed in the App Store

account. Remember this email address and
password. Your Sensi thermostat will
be linked to this email address once
it is registered.

Click this button if it is your

INSTALLING THE SENSI THERMOSTAT

Once you have downloaded the Sensi app,
and have created an account, you are ready
to install the thermostat to your wall and connect
it to Wi-Fi. If no thermostats are registered yet, the
Sensi app will prompt you to add a thermostat. It
will bring you this screen below, where you can
select one of two options: “Install new thermostat
on wall and connect to Wi-Fi” or “Connect already
installed thermostat to Wi-Fi.”

Sensi Security Card

Batteries

The first option will walk through the entire

installation process. If you have not had this

thermostat professionally installed,

choose this option.

The second option is for connecting your

thermostat to Wi-Fi only. If you have had a

professional install your thermostat, and you

just need to connect the Sensi thermostat to

your home Wi-Fi network, choose

this option.

Installer Information

WARNING

On two transformer systems, the transformers MUST be in phase. Measure
the voltage across RC and RH. If more than 12 Volts AC is present between
RC and RH, then the transformers are NOT in phase. To correct this condition,
reverse the secondary low voltage connections at either the Heating or
Cooling transformer.

Thermostat installation and all components of the control system shall
conform to Class II circuits per the NEC code. Do not use on circuits
exceeding specified voltage.

WARNING

Do not use on circuits exceeding specified voltage. Higher voltage will
damage control and could cause shock or fire hazard.

CAUTION

To prevent electrical shock and/or equipment damage, disconnect
electric power to system at maincircuit breaker box until installation
is complete.If “Call For Service” is displayed on your Sensi thermostat,
and E4 or E5 appears where the room temperature should be displayed
or the backlight is flashing, please call our support team immediately
at 888.605.7131.
