Finding the Irrigation Controller for a Carson Valve Box System

"Res/Con by Carson" on a box cover identifies the valve box manufacturer, not the controller. The controller is separate—typically near the electrical panel or in the garage.

Locate the Controller

By main electrical meter (outside)
In garage (wall-mounted)
In laundry/mechanical room
Sometimes in a weatherproof cabinet outside

Once Found

Note brand and model (Rain Bird, Hunter, Irritrol, Orbit, etc.).
Download manual from manufacturer site.
Or visit Sprinkler World (Phoenix area) for hands-on help.

Don't Program the Valve Box

The Carson box just houses valves. The controller is the "brain" with the display and dials. They're connected by buried wires.

Find the controller, get the manual, adjust the schedule. Simple once located.
