Rain Bird TRU8O 8-Station Irrigation Controller — Program-Based, WiFi-Ready, LCD & Surge Protection

This compact yet contractor-grade controller gives you layered programming options for individual zones, letting you tailor run times, start times and watering frequency across up to eight valves. The TRU8O combines an easy-to-read LCD and a rotary dial for fast local setup, while non-volatile memory and built-in surge protection keep your schedules safe in real-world conditions.

How does the TRU8O let me customize watering for different parts of my yard?

The TRU8O supports three independent programs (A, B, C) per zone with up to four start times per program. That structure allows a single zone to follow multiple seasonal or usage patterns without manual intervention.

• Three program tracks (A/B/C) per zone for separate routines
• Up to four start times per program — 12 possible start times per zone
• Flexible day scheduling: weekly, odd/even, or cyclic every 1–30 days

What manual and emergency controls are available on the controller?

The TRU8O provides manual station options for single-zone, all-zone, or program-level activations, plus a Rain Delay feature for short pauses. Built-in diagnostics identify valve issues and temporarily suspend the affected zone so the rest of the system continues running.

• Manual Station — run one zone, all zones, or a whole program
• Rain Delay for 1–14 days or sensor-controlled automatic delays (sensor sold separately)
• Automatic valve troubleshooting with on-screen identification and suspension

Can I scale performance and protect the system from outages or surges?

The TRU8O includes surge protection and non-volatile memory so programming is retained through power interruptions; an internal lithium battery preserves time and date. Professional-level features add interstation delays, master valve/pump relay control and program save/restore for larger systems or contractor use.

• Non-volatile memory stores settings during power loss; lithium clock battery maintains time/date
• Interstation delay adjustable from 1 second to 9 hours for pump and pressure management
• Save/restore programming, master valve or pump start relay, and factory reset options

Who this is for: The Rain Bird TRU8O is aimed at homeowners, landscapers and small contractors who want robust, weatherproof control over up to eight irrigation zones with advanced scheduling options. If you need local simplicity now and the option to convert to WiFi-based remote control later (LNK2 WiFi Module sold separately), the TRU8O offers a durable, feature-rich platform that fits most 24 VAC irrigation valves and outdoor installations.
