Hard Wiring
An enclosure is required for hard wiring installations and/or out-
door 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

Got thick wires?
The controller is designed for 18 gauge sprinkler, solid copper
wire. Up to 14 gauge wire can be inserted into the terminals with-
out causing damage. If you have thicker gauge wires, we recom-
mend retrofitting with 18 gauge wires using a terminal strip. We
recommend the exposed wire to be between 3/8 to 1/2” inch long
and straight.
