Understanding Your Hunter Controller

Hunter sprinkler controllers are designed to automate your irrigation system by delivering water to different areas of your landscape at specific times. The controller acts as the brain of the system, sending electrical signals to solenoid valves that open and close to release water through sprinkler heads. Understanding how your particular model operates is essential before attempting to program it.

Most Hunter controllers allow you to create multiple watering programs, typically labeled as Program A, Program B, and sometimes Program C. Each program can have its own schedule, start times, run durations, and active days. This flexibility enables you to customize watering for different plant types, sun exposure areas, and soil conditions within your landscape.

The interface varies by model. Dial-based controllers require you to rotate a central knob to navigate between settings, while digital models use buttons and a display screen. Some newer models include touchscreen interfaces with intuitive menus. Regardless of the interface type, the fundamental programming steps remain largely the same.

Basic Programming Overview

Programming a Hunter sprinkler controller generally follows a consistent sequence regardless of the model. The main steps include setting the date and time, creating or modifying programs, assigning zones to programs, setting run times, configuring start times, and selecting active days. Let’s break down each of these components in more detail.

The date and time setting is crucial because it serves as the reference point for all scheduled activities. Without accurate time information, your controller cannot execute watering schedules properly. Most modern Hunter controllers automatically adjust for daylight saving time, but you should verify this setting.

Programs are the foundation of your irrigation schedule. Each program contains a complete set of instructions including which zones to water, how long to water each zone, when to start watering, and on which days to water. You can think of programs as templates that the controller follows automatically.

Zones represent individual sections of your irrigation system. A typical residential system might have 6 to 12 zones, each controlling a different area of your landscape. Assigning zones to programs determines which areas receive water under each program’s schedule.

Step-by-Step Programming Guide

Now that you understand the basic concepts, let’s walk through the actual process of programming your Hunter sprinkler controller. While specific button presses may vary by model, the overall approach remains consistent.
