Rain Bird irrigation regulator Key Features & Benefits
Smart WiFi Control (Optional)
When paired with the LNK2 WiFi Module, the ESP-ME3 allows full remote control through the free Rain Bird mobile app on iOS and Android. You can start, stop, or adjust irrigation schedules from anywhere.. whether you’re inside your villa or traveling outside Saudi Arabia.
This means less site visits, faster adjustments, and complete peace of mind.
Up to 30% Water Savings
Connected to WiFi and a WR2 Rain Sensor, the controller automatically adapts irrigation schedules based on real weather data. No watering during rainfall or high humidity.
The result: up to 30% annual water savings, healthier plants, and lower utility bills.. critical in regions with water scarcity.
Expandable from 4 to 22 Stations
Start small and grow confidently. The ESP-ME3 begins with 4 stations and expands up to 22 by adding ESPSM3 three-station expansion modules.. without shutting down or replacing the controller.
Ideal for projects that evolve over time, from home gardens to expanding farms.
Large 3-Inch Backlit LCD Screen
The clear, high-contrast display remains readable in garages, outdoor enclosures, and even under direct sunlight. The intuitive interface simplifies programming for both homeowners and technicians.
Advanced Scheduling Flexibility
Create up to 4 independent programs, each with 6 start times. Scheduling options include:
- Specific days of the week
- Odd or even days
- Cycles every 1–30 days
This flexibility allows precise water delivery for lawns, trees, shrubs, and flower beds.. each with different water requirements.
Master Valve & Pump Control
A dedicated electrical circuit supports Master Valves and pumps, enabling centralized water control and added protection against leaks. You can activate or deactivate the master valve per station, enhancing system safety and operational control.
Built for Saudi Climate Conditions
With an IP24 rating and heat resistance up to 65 °C, the ESP-ME3 performs reliably during Saudi summers. While suitable for indoor and outdoor installation, mounting it in a garage or protective enclosure is recommended for extended lifespan.
Typical Use Cases in Saudi Arabia
- Luxury villas and residential homes: Zoned irrigation for lawns, trees, and flower areas with mobile control from inside the house.
- Farms and rest houses: Cost-effective irrigation for seasonal crops and trees using drip or sprinkler systems.

- Shaded parking areas with trees: Efficient irrigation that preserves tree health without excessive water use.
- Small home gardens (4–6 zones): Smart control today with easy expansion tomorrow.
Installation & Initial Setup Guide
Before Installation
Choose a dry, protected location. Although IP24 rated, installation inside a garage or weatherproof enclosure is strongly recommended. Ensure a nearby 220 V power source is available.
Plan the number of stations and prepare a clear irrigation layout before wiring.
Installation Steps
Step 1: Mounting the Controller
- Install on a flat wall, approximately 1.5 meters above ground
- Secure using the included screws (preferably on concrete)
- Leave at least 15 cm clearance for wiring and door access
Step 2: Power Connection
- Connect the pre-installed power cable to a 220 V source
- Ensure the circuit breaker supports at least 0.3 A
- Do not power on until all wiring is complete
Step 3: Station Wiring
- Connect each valve solenoid wire to its corresponding station terminal
- Connect all common wires to the COM terminal
- Use 0.75–1.5 mm² cables and tighten screws securely
Step 4: Master Valve / Pump (Optional)
- Connect to the MV/Pump terminal
- Recommended for added protection and leak prevention
Step 5: WiFi Module (Optional)
- Insert the LNK2 module into the designated slot
- Follow pairing instructions with your home WiFi
- Download the Rain Bird app from App Store or Google Play
Step 6: Testing & Programming

Important Safety Notes
- Avoid frequent pump restarts; wait at least 5 minutes between cycles (15 minutes for submersible pumps).
- Three-phase pumps require proper protection panels against overcurrent and phase loss.
- Never operate pumps without water; dry running is not covered by warranty.
- Run the system at least once weekly to prevent valve seizure.
- Drain water from pipes and pumps if temperatures drop below 0 °C.
