Take a photo of your wiring
Throw away any jumper wires
This can be helpful for troubleshooting with our technical
support team if necessary. The picture you take will
be saved to your camera roll or photo gallery.
Throw Away Any Jumper Wires
If you see a jumper wire, remove it. Your new
thermostat has the jumper wire built in.
Leave all other wires connected to the
thermostat.
Sensi has a jumper wire built into it, and you will
not need any jumper wires from your old unit.
Optional: take a photo of your existing
thermostat wiring in case you need it for
reference later. The photo will be saved to
your camera roll.
