Programming the ESP-ME3 Controller
The ESP-ME3 controller offers program-based scheduling for tailored irrigation plans, allowing customization of run times, start times, and days of the week for efficient water management.
3.1 Understanding Program-Based Scheduling
Program-based scheduling allows you to create customized irrigation plans by defining specific start times and run times for each station. This method ensures that all stations in a program run sequentially, optimizing water distribution. Each program can have multiple start times, and run times can be set from 1 minute to 6 hours. Avoid setting multiple start times within the same program to prevent excessive watering cycles. This feature ensures efficient and tailored irrigation management for your lawn or garden.
3.2 Setting Watering Schedules and Start Times
To set watering schedules, select a program and define start times (up to six per program). Choose specific days of the week or intervals like every 2 or 3 days. Run times can be set from 1 minute to 6 hours for each station. Avoid setting multiple start times within the same program to prevent overlapping cycles. This feature ensures precise control over irrigation, aligning with your lawn’s needs and promoting water efficiency. Adjust schedules as needed for optimal results.
3.3 Customizing Run Times and Days of the Week
Customize run times from 1 to 240 minutes per station or program. Assign specific days of the week or select odd/even cycles for watering. For added flexibility, set intervals like every 2 or 3 days. Adjust run times easily using the seasonal adjustment feature (5-200% of the programmed time). Enable rain sensor compatibility to suspend watering during rain. Review and adjust settings to ensure optimal watering schedules tailored to your landscape needs, promoting water efficiency and healthy plant growth.
Advanced Features of the ESP-ME3
The ESP-ME3 offers advanced features like flow sensor integration, rain sensor compatibility, and seasonal adjustments. These tools enhance water efficiency and customization for optimal irrigation management.
4.1 Flow Sensor Compatibility and Configuration
The Rain Bird ESP-ME3 supports flow sensor integration to monitor water usage and detect irregularities. To configure, remove the yellow jumper wire from the SENSOR terminals and connect the sensor wires. The controller learns the expected flow rate for each station and suspends irrigation if deviations exceed 30%. This feature helps prevent water waste and ensures efficient irrigation management. Proper installation and setup are crucial for accurate flow monitoring and system performance.
4.2 Rain Sensor Integration and Settings
The Rain Bird ESP-ME3 integrates with rain sensors to suspend irrigation during rainfall. Connect the sensor wires to the SENSOR terminals, ensuring they are routed separately from power wires. The controller supports normally closed rain sensors. When the sensor detects rain, it triggers a suspension of automatic watering. Enable or disable this feature via the Sensor ON/OFF setting. Proper installation ensures water conservation and prevents overwatering. Refer to the manual for specific compatibility and wiring instructions.
4.3 Seasonal Adjustments and Delay Functionality
The ESP-ME3 offers seasonal adjustments to modify watering schedules based on weather conditions. Adjust run times by 5% to 200% to optimize water usage. Additionally, the delay functionality allows suspending irrigation for up to 14 days, resuming automatically afterward. This feature prevents watering during unfavorable conditions, ensuring efficient water use and system flexibility. Use these settings to tailor your irrigation system to seasonal changes without altering the entire program.
