Mark screw locations.
Use the Mounting Template at the end of this guide
to mark where you want to install your Generation 2.
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 faceplate of the Generation 2. 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!

Tear here to detach the mounting template.

While referencing the photo of your previous
wiring, insert the wires into the appropriate
terminals. Things not matching up? Visit
rachio.com/wiring for tips on advanced wiring.
Connect your wires.
STEP 4
BEST PRACTICE: WIRING
Insert screwdriver tip into the
rectangular wire terminal.
Press in until the rectangular terminal
is flush with the gray terminal bar or
you feel a click.
Insert your wire, then release the
rectangular terminal.
Tug the wire to make sure it is secure!

Sensor Wires (Optional)
You are able to connect up to
two rain or flow sensors to your
controller using the “S1,” “S2,”
and “SC” and “SP” terminals.
For more information, visit
rachio.com/sensors.
Master Valve
Not all systems have a master
valve. Master valve wires are often
labeled “M,” “MV,” or “Pump.” If
you have a master valve, wire it
into the “M” terminal.

Common Wires
Common wires are often labeled
“C” or “Com.” You can insert them

Insert the power connector into the power jack located at
the bottom right of the wiring bay. Then, plug the power
adapter into the outlet.
