Index

The Toro GDC-200 combines modular flexibility, ease of use and increased programmability in a single controller.

Modularity means flexibility. The GDC-200 can control up to 200 stations.

The intuitive user interface is easy to use and includes a backlight for improved visibility in low-light conditions, yet it is completely viewable in direct sunlight. The faceplate’s combination of menu keys, navigation arrows and Input Dial allows for easy menu navigation and quick settings establishment.

With 10 irrigation programs, the GDC-200 allows programming flexibility.

Pressing a menu key on the GDC-200 will display menu items. Items with fields containing values that can be edited

are called Entry Fields. Use the Arrow Keys to navigate through the menus and entry fields.

Modify any selected value by scrolling through the selection using the Input Dial . Values will be saved

automatically when you exit an entry field or press another menu key. Pressing the HOME Key will also save

any modification and revert back to Home display.

Additionally, if no keypad activity is detected within five minutes, the controller will automatically save any

modifications and revert back to Home display.
