Hunter STPi Controllers are a discontinued item - no longer available through Hunter. As a replacement, we recommend the Rain Bird ESP-RZX Controller series.
Rain Bird's Simple-to-Program (STPi) Controllers are the easiest controllers in the irrigation industry to program and operate. In fact, the STPi controller is so easy to operate you won't even need to read the instructions.
The STPi Controller is an indoor controller that has 4, 6 or 9 zone capability. The STPi Controller allows the user to simply enter a custom irrigation schedule for each zone that matches the plants specific irrigation needs.
Simple to use "At-a-Glance" programming allows you to see all of the irrigation schedule information for each specific zone at the same time on the controller.
