Wiring
Hard Wiring
An enclosure is required for hardwiring installations and/or
outdoor installation. For details, reference
www.rachio.com/outdoors.
Multiple Controllers
If you’re using more than one controller, do not share ANY wires
between them - a relay is required. For further details, reference
www.rachio.com/relay.
Thick Guage Wires
The controller is designed for 18-gauge sprinkler, solid copper
wire. Up to 14-gauge wire can be inserted into the terminals
without causing damage. If you have thicker gauge wires, were
commend retrofitting with 18-gauge wires using a terminal strip.
