3.2. Creating Watering Schedules
The controller supports up to 16 custom watering schedules across 8 zones. You can define various watering intervals:
- Daily
- Odd days
- Even days
- Specific days of the week
- Daily interval (e.g., every 2 days)
- Hourly interval
Each schedule can be applied to one or multiple zones. The app provides a step-by-step guide for schedule creation.

3.3. Irrigation Methods: Cycle and Soak
The controller offers two primary irrigation methods:
- Cycle and Soak: This method applies water in shorter bursts with pause periods, allowing the soil to absorb water more effectively. This prevents runoff and promotes healthier soil conditions.
- No Cycle, No Water: This is the standard continuous watering method.

3.4. Smart Weather Skips
The HiOazo HSC-800W integrates with local weather data to automatically adjust or skip watering schedules, optimizing water usage and protecting your plants.
- Smart Rain Skip: Automatically skips watering if rain is detected or predicted.
- Freeze Skip: Prevents watering when temperatures drop below freezing to avoid ice formation and plant damage.
- Wind Skip: Skips watering during high winds to prevent water waste due to drift.
- Seasonal Adjust Skip: Adjusts watering based on seasonal changes in plant water requirements.

4. Maintenance
The HiOazo HSC-800W is designed for low maintenance. Follow these guidelines to ensure optimal performance:
- Cleaning: Periodically wipe the exterior of the controller with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Firmware Updates: Ensure your app and controller firmware are up-to-date. The app will typically notify you of available updates.
- Winterization: In regions with freezing temperatures, it is recommended to disconnect the controller from the power supply and store it indoors during winter months to prevent damage from freezing water in the pipes or unit.
