If you want to set up the sprinkler controller all by yourself, you will only have to follow a few instructions given below. Here, take a look:

Step 1

Test the old system to make sure that everything is working properly. Thereafter, take a photo of the wiring inside the existing controller to refer to during the installation process. Now, take out the controller from the wall.

Step 2

Use the Mounting Template to mark where you would like to install the Rachio 3.
Now, you will have drill holes in the locations you have marked for the anchors. You need to use a 3/16 inch bit for drilling through the drywall. Thereafter, you need to use a hammer to tap on each anchor gently to make sure they stay in place.

Step 3

Your next step involves removing the magnetic faceplate of the device. Now, mount the controller by screwing into the wall using the screws that have been provided to you.

Then to mount the template, make sure that the lower holes are at the same level. Take a pencil and mark every hole’s center. Check if the wires have enough slack for reaching the drill icon.

Step 4

Now, you have to connect the wires. Make sure that you insert the wires in the right terminals.

C: Common wires are usually labeled as ‘Com’ or ‘C’. You can put them into any of the terminals marked ‘C’.

Zone Wires: Zone wires are referring to the landscape’s zones. So, you have to put them into numbered, blue terminals.

M: It’s the Master Valve. Not every system comes with a master valve but if it does, it is labeled as ‘MV’, ‘M’, or ‘Pump’. So, if there is a master valve, insert them in the ‘M’ terminal.

S1-2 or 24 VAC: You can connect up to 2 rain or flow sensors for the controller using ‘S1’, ‘S2’, or 24VAC sensor power terminals.

Step 5

Finally, you have to download the Rachio app from Google Play Store or App Store. Once you are done downloading, create an account.

Step 6

Launch the app and choose the option ‘App Controller’. Follow the instructions on the app to complete the process.
Once you find the controller online, the light bulb flashes blue light. So, it’s time to replace the magnetic faceplate.

Step 7

Voila, your controller is online. Now, you can use the app for creating a schedule or customizing your zones.
