One crucial feature that plays a key role in optimizing water usage is the "Zone Minimum Rollover Threshold" (Minimum Watering Time).
What is it?
The Zone Minimum Rollover Threshold is a setting within smart irrigation controllers that allows users to specify the shortest duration for their sprinklers to operate during a scheduled watering session. This feature ensures that even if a user-set duration is below the defined threshold, the system adjusts to meet the minimum requirement.
How to enable it?
To enable this feature, use the RainMachine mobile/web apps and open:
Zone - Edit Zone - Advanced Settings - Minimum Rollover Threshold
Enter the desired time in seconds and then save the zone settings.
Let's say you've set your Zone Minimum Minimum Rollover Threshold to 60 seconds. If a scheduled watering session is initially programmed for 45 seconds, the smart irrigation system intervenes. Recognizing that this falls below the specified minimum, it automatically extends the watering time to meet the 60-second threshold. Consequently, your plants receive the required minimum irrigation.
Carrying over unused time
In our example, the additional 15 seconds (the difference between the scheduled 45 seconds and the minimum 60 seconds) are carried over to the next scheduled watering cycle. This intelligent carry-over mechanism ensures that any unused time is efficiently utilized in subsequent watering sessions.
1. Optimal Plant Health
Ensures that your plants receive the minimum watering necessary for their health and growth.
2. Water Efficiency
Prevents under-watering by automatically adjusting durations below the set threshold, promoting responsible water usage.
3. Smart Scheduling
Enhances the intelligence of your irrigation system by dynamically adapting to varying watering durations.
Reduces the need for constant manual adjustments, providing a hassle-free approach to maintaining your landscape.
In conclusion, the Zone Minimum Rollover Threshold in smart irrigation systems empowers users to set a baseline for their sprinkler runtimes, ensuring plants receive the necessary care while optimizing water usage. This feature exemplifies the intelligence and efficiency that modern irrigation technology brings to the forefront, making it an indispensable tool for conscientious gardeners and homeowners alike.
