Rain Bird ESP-9V Battery-Operated Controller

Thank you for choosing the Rain Bird ESP-9V battery-operated controller. This manual provides detailed instructions for installation, programming, and operation.

Controller Overview

The ESP-9V controller is designed for battery operation, making it ideal for locations without AC power. It uses two 9-Volt alkaline batteries, and can function with either one or two batteries.

Installation

Mounting the Controller: Mount the controller in a suitable location, protected from direct sunlight and extreme temperatures. Ensure it is accessible for programming and maintenance.

Wiring: The controller connects to solenoid valves. Refer to the wiring diagrams provided in the original documentation for specific connections. Ensure all connections are secure and properly insulated.

Programming

The controller offers flexible programming options to manage your irrigation schedule:

Setting the Date and Time

Ensure the controller's internal clock is set accurately to the current date and time for proper watering cycles.

Setting Watering Days

Select the days of the week for watering. Options typically include specific days, odd/even days, or interval watering.

Setting Start Times

Program the desired start times for each watering cycle. Multiple start times can be set per day.

Setting Watering Durations

Specify the length of time each station will water. This can be adjusted based on plant needs and weather conditions.

Watering Adjustments

Seasonal Adjust: Modify watering durations based on seasonal changes without reprogramming the entire schedule. This is often represented as a percentage increase or decrease.

Rain Delay: Activate a rain delay to suspend watering for a specified period (e.g., 24, 48, 72 hours) when rain is expected or has occurred.

Manual Watering: Initiate manual watering for specific stations or all stations as needed.

Features and Functions

Battery Indicator: A visual indicator shows the battery level, alerting you when replacement is needed.

Rain Sensor Input: The controller is compatible with rain sensors to automatically prevent watering when sufficient rainfall has occurred.

Multiple Programs: Some models may support multiple independent watering programs for different zones or plant types.

Troubleshooting

Controller not turning on: Check battery installation and ensure batteries are new and correctly oriented. Verify battery contacts are clean.

Valves not opening: Ensure correct wiring to the valves. Check solenoid condition and battery power.

Incorrect watering times: Verify that the date, time, and programmed start times are set correctly.

Maintenance

Regularly check and replace the 9-volt batteries as indicated by the battery indicator or at least annually. Keep the controller clean and free from debris.
