Installation

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. 
First, choose which thermostat you purchased. The Sensi Touch Wi-Fi  

Thermostat option is for the following model numbers:

 

• 1F95U-42WF

 

• ST75

Note:  You can check your model number on the back of the thermostat faceplate.

Install path

After creating an account, signing in and choosing your model, the app will 
ask you whether or not the thermostat is already on the wall. You will either 
choose “No, it needs to be installed,” or “Yes, it is on the wall.” 

The first option will walk through the entire installation process. If you  

did not have 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.

No, it needs to be installed.

This option will walk you through the entire installation process, including 

identifying and connecting your wiring, as well as connecting to Wi-Fi. The 
Sensi app will walk through a step-by-step process for installation.
