Programs can be set to run on specific days or intervals, and adjustments can be made without affecting other programs. The controller’s interface simplifies the process of creating and managing multiple programs, ensuring precise irrigation control. This feature is particularly useful for managing diverse watering requirements across different areas of a property. Additionally, the non-volatile memory retains program settings even during power outages, maintaining consistency in irrigation schedules. The ability to set multiple programs enhances the controller’s adaptability to different environmental conditions and plant needs, ensuring efficient water usage and healthy plant growth.
3.3 Adjusting the Rain Delay Function
The Rain Delay feature allows users to pause irrigation for 1 to 7 days, preventing unnecessary watering during rain or extreme weather. To adjust the delay, press the PROG button to select the desired program, then use the DIAL to choose the delay option. Once set, the controller will temporarily halt watering cycles without altering the programmed schedules. This feature is ideal for water conservation and maintaining healthy plant growth by avoiding overwatering. The Rain Delay function ensures that irrigation resumes automatically after the specified period, providing seamless operation;
Manual Operation Mode
Manual Operation Mode allows users to start watering cycles immediately, bypassing programmed schedules. This feature provides direct control over irrigation, enabling quick adjustments as needed.
4.1 Starting a Manual Watering Cycle
To initiate a manual watering cycle, switch the controller to Manual mode. Press the Manual button to begin watering the first zone. Use the NEXT button to cycle through additional zones. The system will water each zone sequentially based on the set run times. To stop watering, press the OFF button. This feature allows for immediate, direct control over irrigation, ensuring flexibility and precision in watering your landscape as needed.
4.2 Bypassing the Rain Delay Feature
To bypass the Rain Delay feature on your Rain Dial controller, press and hold the Manual button until the display indicates the feature is deactivated. This allows watering to proceed regardless of weather conditions. Note that bypassing the rain delay is temporary and will revert to automatic settings after the current cycle. Ensure the sensor is properly connected to maintain water-saving functionality when not in manual override mode. Always verify sensor operation after bypassing to avoid unintended watering patterns.
Advanced Settings and Customization
Explore advanced features like semi-auto mode, multiple programs, and special functions to tailor your irrigation system. Customize settings for optimal water management and system performance.
