• Seconds Based Irrigation: Run times can be set in 1-second intervals, from 7 seconds to 18 hours.
• Calendar Days Off: Schedule specific days off in advance to prevent irrigation during events.
• Permanent Days Off: Exclude recurring days of the week (e.g., mow days) regardless of watering frequency.
• Additional Images: Upload custom images to quickly identify stations and sites.
• Interstation Delay: Set delays between station turn-off and turn-on to protect hydraulics.
• Rain Delay: Pause irrigation for up to 14 days with auto-resume.
• Pause Active Irrigation: Temporarily pause a station to address issues (e.g., broken nozzle) and resume from where it left off.
• Search & Filter: Easily locate controllers by name, type, connection status, or battery level.
• Controller Grouping: Organize multiple battery-operated controllers into groups for streamlined on-site operations.
• Quick Status: View essential statuses of connected controllers, including auto/off mode, rain delay, battery life, and Bluetooth connection.

3.2. Wiring Connections

Connect the controller to your irrigation system's valve(s) and common wire. The ESP-BAT-BT1 operates one valve per station.

• Ensure all connections are secure and waterproof, especially given the controller's IP68 rating for submersion.
• The maximum wire run between the controller and the TBOSPSOL DC-latching solenoid is 98.4ft (30m) using 1.5mm² (16 AWG) extended wire.
• Refer to the "Maximum Wire Run" in the Specifications section for detailed wire gauge distances.

4. Operating Instructions

All programming and operational control of the ESP-BAT-BT1 controller are managed through the Rain Bird 2.0 mobile application.

4.1. Basic Programming

The controller supports four independent programs (A, B, C, D), each capable of having up to 8 start times per day. Stations can be assigned to multiple programs with different watering run times.

• Setting Run Times: Adjust run times from 7 seconds to 9 hours (up to 18 hours with 200% seasonal adjust) in 1-second increments.
• Watering Days: Choose from custom, even, odd, or cyclical watering day modes. You can also set permanent days off to exclude specific days of the week.
• Seasonal Adjust: Utilize the Global Monthly Seasonal Adjust feature to modify watering duration for the entire year, from 0% to 200%, in 1% increments.

4.2. Advanced App Features in Operation

• Manual Watering: Initiate manual watering cycles directly from the app for specific stations or programs.
• Rain Delay: If rain is expected, use the Rain Delay feature to suspend irrigation for up to 14 days. The system will automatically resume after the set delay.
• Cycle & Soak: To prevent water runoff, enable Cycle & Soak. This feature divides the total watering time into shorter intervals, allowing water to absorb into the soil.
• Offline Mode: Make programming changes in the app even without a Bluetooth connection. These changes will be saved and synchronized with the controller once a connection is re-established.
• Controller Sharing: Share access to your controller with other users (e.g., maintenance teams) through the app for collaborative management.
