5. Operating Instructions

5.1 General Operation and Display

The controller features an LCD with backlight for clear visibility. Use the dial and buttons (+/DELAY, −/LOCK, /OK) to navigate and set your watering programs.

5.2 Soaking Watering Function

The soaking function provides an intermittent watering program, allowing water to permeate the soil more effectively. This prevents runoff and overflow, ensuring plants are well-hydrated.

This diagram visually explains the 'Soaking Watering' feature, showing how the controller alternates between watering and soaking periods (e.g., 5 minutes watering, 10 minutes soaking) to allow water to permeate the soil effectively, preventing runoff.

5.3 Watering Frequency Modes

The controller offers three flexible watering frequency modes:

• Interval Watering: Set watering to occur every X number of days.
• Assigned-day Watering: Choose specific days of the week for watering.
• Everyday Watering: Water daily.

This image illustrates the three distinct watering frequency modes available: Interval Watering (e.g., every X days), Assigned-day Watering (specific days of the week), and Everyday Watering, allowing users to customize their irrigation schedule.

5.4 Independent Watering Plans

You can set up to three independent watering plans (P1, P2, P3) to manage different watering needs across your garden. Each plan can have its own start time, end time, soaking time, and watering duration.

The image demonstrates the flexibility of setting up to three independent watering plans (P1, P2, P3), each with its own start time, end time, and optional soaking/watering durations, suitable for different areas of a garden.

5.5 Rain Delay Function

To conserve water during rainy periods, the controller features a rain delay function. You can postpone the watering schedule for 24 hours, 48 hours, or 72 hours. Watering will automatically resume after the selected delay period.

5.6 Child Lock

Enable the child lock feature to prevent accidental changes to your programmed watering schedule. This is activated by a simple press of a button.

The image displays the sprinkler controller with icons indicating the Rain Delay function, which postpones watering for 24, 48, or 72 hours, and the Child Lock feature, designed to prevent accidental program changes.

5.7 Water Flow Meter

The precise water flow meter displays real-time water flow speed, single water flow, the average water flow of the last 7 days (excluding today), and total water flow. This helps in monitoring water usage, preventing overwatering, and saving on water bills.

This image highlights the integrated water flow meter, which accurately measures water usage. It also lists key specifications such as working pressure, water inlet/outlet size, hose type, and water flow measurement range.

6. Maintenance

• Filter Cleaning: Regularly inspect and clean the filter to ensure optimal water flow and prevent clogging. Replace the filter if it appears worn or damaged.
• Winter Storage: During freezing temperatures (below 37℉ / 3℃), disconnect the controller from the faucet and store it indoors to prevent damage from freezing water.
• Battery Replacement: When the battery is low, the controller will automatically close the water valve to prevent continuous watering and save all current settings. Replace batteries promptly when the low battery indicator appears.

The image depicts the low battery protection feature, where the controller automatically closes the water valve when battery power is critically low and saves all settings before the battery completely runs out.

7. Troubleshooting

If you encounter issues with your HiOazo Sprinkler Controller, please refer to the following common solutions:

• No Water Flow: Check if the water faucet is fully open. Ensure the filter is clean and not clogged. Verify that the batteries are not depleted and are inserted correctly. Check your programmed schedule for correct start times and durations.
• Display Not Working: Replace the batteries with new ones. Ensure the battery compartment is securely closed.
• Incorrect Watering Times: Review your programmed watering plans (P1, P2, P3) to ensure all settings (start time, end time, watering duration, soaking time) are correct. Check if the child lock is enabled, preventing accidental changes.
• Water Leakage: Ensure all connections (faucet, water flow meter, hose) are tightly secured. Check the rubber washers for proper seating and replace if damaged.
