How do I install a Generation 2 (Gen 2) Rachio outdoors?

Depending on where you live, controllers are usually mounted indoors or outdoors. If outdoors, they're usually hardwired and can be a bit tricky to change out. The Generation 2 Rachio Controller has a custom outdoor enclosure that makes it easy to swap out an existing controller and have a nice clean, elegant looking controller outdoors that can be locked up and hardwired.

Installation Steps:

Before starting installation of this fixture or removal of a previous fixture, disconnect the power by turning off the circuit breaker or by removing the fuse at the fuse box. PLEASE CONSULT A QUALIFIED ELECTRICIAN IF YOU HAVE ANY ELECTRICAL QUESTIONS.

  1. Install the enclosure
    • Take photos of your wiring and label any duplicate colors to avoid confusion
    • Remove the old enclosure and controller from the wall
    • If you have wiring conduit coming into the old enclosure, make sure to account for any fittings and/or space requirements that differ on the Rachio enclosure
      • If the conduit does not align, cut and re-route as needed 
    • Conduit opening measurements
      • Hardwired power: 0-7/8 inch
      • Zone wiring: 1-1/8 inch (knockout enlarges to 1-3/8 inch) 
    • Mount the Rachio enclosure to the wall
      • If mounting to drywall, use anchors
  2. Hardwire Power
    • The controller will use the supplied power adaptor for both outlet and hardwire applications; connect the power using one of the two methods below:
      • Outdoor outlet: If your old controller had a power adapter and plugged into an outdoor rated & covered outlet, please use the same outlet with the Rachio's power adaptor. 
        • Simply feed the power adaptor wiring through the bottom right hole of the enclosure and leave 6-9" of slack.
      • Power Adaptor doesn't fit in your outdoor rated & covered outlet?
        • First, you’ll need a couple of extra parts that are readily available on Amazon or at a local hardware store.  We recommend the following:
        • Here’s what you should have to get started 
        • Follow the steps listed in hardwiring (below), then plug the pigtail into your outlet!
      • Hardwired power: If your old controller did not have a plug, you'll need to hardwire the outlet inside the Rachio enclosure. 
        • Unscrew the two screws on the lid of the Hardwiring Bay to access the enclosure wires of the outlet. 
        • TURN OFF POWER to your hardwire power source. Clean and straighten the wires. Attach a strain relief bushing (not included) if you have slack in the wire -or- if you're installing a pigtail. Position the bushing about an inch below the beginning of the black insulation.
        • Feed the power supply wires through the bottom left hole of the enclosure. 
        • Attach the wires using connector caps 
          • Black (or red) supply wire to the black enclosure wire. This is your power supply wire, also known as "hot".
          • White supply wire to the white enclosure wire. This is typically the common/neutral wire. 
          • If you have a ground wire (usually green) attach it to the enclosure ground wire.
        • Wrap all wire connections with electrical tape for a secure connection.
        • Close Hardwiring Bay of the outdoor enclosure with the cover and two screws that came with the enclosure. 
  3. Mount the controller
    • Pull valve and sensor wires through the center opening on the controller's base. Mount the controller to the enclosure using the included bolts
      • Mounting holes: top center + two bottom (do not use the center middle 
      • DO NOT install the cover on the base of the controller after it's mounted in the enclosure.
