Label Your Wires
The Sensi app will show you
how to label your old wires.
Wire labels are included
in your Sensi thermostat
packaging. Based on the
wires you selected in Step 5,
the app will show you which
labels to put on your old wires.
Note: These pictures may be different
than what you will see on your Sensi
app. It should show each wire that you
chose from the wire picker, and what
terminal to attach it to on your Sensi
thermostat.
