Mark screw locations.
Use the Mounting Template at the end of this guide
to mark where you want to install your Rachio 3.
For Drywall Installation:
Drill holes at marked locations for the anchors. Use
a 3/16 inch bit to drill through the drywall, then use
a hammer to gently tap each anchor into place.
STEP 2

In with the new!
Remove the Rachio 3’s magnetic faceplate. Mount
your new controller by screwing it onto the wall
using the provided screws.
STEP 3

Mounting Template
Ensure the lower holes are level, and use a
pencil to mark the center of each hole.
Make sure your wires have enough
slack to reach the drill icon above!
