Orbit 57594 4-station Indoor Irrigation Timer

Product Description

The ORBIT 57594 is a 4-station indoor irrigation timer built for residential sprinkler and drip systems. It runs on hardwired 120-volt AC power with a transformer output of 26 volts AC at 500 mA or 22.5 volts AC at 600 mA, and includes an auto-reset breaker for circuit protection. The Easy-Set Logic dial interface and large LCD make programming straightforward in the field. Each station supports run times from 1 to 240 minutes, and the controller supports up to 8 start times per day, making it suitable for new sod establishment, drip zones, or any schedule that requires frequent short cycles.

The 57594 is designed for indoor installation in residential irrigation applications. It fits standard irrigation controller enclosure locations near a power source and low-voltage valve wiring. The controller supports independent dual watering programs configurable by days of the week, watering intervals, or odd/even days. A water budgeting function lets technicians adjust seasonal run times as a percentage without reprogramming each zone individually. The built-in rain sensor terminal with bypass switch simplifies wiring of a compatible rain sensor, which is sold separately.

Compatibility

Designed as an OEM-style replacement or upgrade controller for 4-zone residential indoor irrigation systems using standard 24-volt AC solenoid valves.

Installation Notes

Installation should be performed by a licensed irrigator or qualified contractor familiar with low-voltage irrigation wiring practices. Disconnect AC power at the source before making any wiring connections to the controller terminals. The unit requires a hardwired 120-volt AC supply; route and secure line-voltage wiring in accordance with applicable NEC requirements. Two AA batteries, not included, are recommended for program memory backup in the event of a power interruption.
