Orbit 57899 9-zone Irrigation Timer Hardwired

Product Description

The ORBIT 57899 is a 9-zone irrigation controller designed for residential and light commercial sprinkler systems. It supports up to 9 independent stations or valves and includes a built-in transformer that allows direct hardwire connection to a 120-volt AC breaker box. For indoor installations, a standard 3-prong plug is included. Two independent programs can each be scheduled to run multiple times per day, with run times adjustable from 1 to 99 minutes per zone. A water budgeting feature lets technicians scale watering duration seasonally without rebuilding the program schedule from scratch. The heavy-duty cabinet is UV-resistant and rated for both indoor and outdoor installation.

This controller is suited for residential irrigation systems and light commercial landscape applications where up to 9 valve zones require scheduled control. It is appropriate for new installations and direct replacements of existing multi-zone timers. The unit can be mounted indoors in a utility room or garage, or installed in an outdoor enclosure. The built-in transformer eliminates the need for a separate 24-volt transformer in the control circuit. Irrigation contractors, landscapers, and experienced DIYers typically handle installation. A rain delay function allows the program to be postponed for 24, 48, or 72 hours, and an external rain sensor can also be connected to automate rain-based shutoff.

Installation Notes

Installation should be performed by a licensed irrigator, electrician, or qualified contractor where local codes require it. Shut off power at the breaker before making any hardwired connections to the 120-volt AC supply. When wiring to a breaker panel, follow all applicable NEC requirements for low-voltage irrigation control wiring. If mounting outdoors, ensure the cabinet door is fully latched to maintain weather resistance.
