By correctly setting the current date and time, the Node Controller will be ready to execute watering schedules accurately.
⏱️ Setting the Start Times
The Node Controller allows users to program up to four start times for each program. Start times determine when watering operations begin. To set the start times, follow these steps:
- Press the center button to navigate to the second feature, which displays the start time for Program A.
- Use the plus button to increase the start time and the minus button to decrease it.
- Navigate to the second, third, or fourth start time by using the right arrow.
- To delete a start time, select the desired start time and use the plus button to set it to "Off."
- Press the center button to return to the home screen.
It's important to note that the start times are specific to the program and not the individual stations. By configuring the start times, users can ensure that watering operations begin at the desired times.
⌛ Assigning Run Times to Stations
Each station in the Node Controller can be assigned a specific run time, ensuring that plants receive the appropriate amount of water. Follow these steps to assign run times to the stations:
- Scroll through the screens using the center button until you reach the station run time for Program A.
- Use the plus button to set the run time for each station. Only assign run times to stations within the same program that have the same watering day requirements.
- Use the right arrow to navigate to the next station and set its run time. Repeat this step for all stations within the program.
- After completing the assignments, scroll through the screens to the off screen and return to the home screen.
By assigning run times to stations, users can ensure that each plant or zone receives the appropriate amount of water based on its requirements.
📅 Configuring Days to Water
The Node Controller provides flexibility in scheduling watering operations by allowing users to choose specific days, odd or even days, or interval mode. Follow these steps to configure the days to water:
- Use the center button to navigate to the water day feature.
- Use the right arrow to scroll through the days of the week. Use the plus button to select a watering day and the minus button to deselect it.
- To choose odd or even days, navigate to the "Odd" or "Even" option respectively and use the plus or minus button to select or deselect it.
- Users can also opt for interval mode by using the left arrow to navigate, selecting a specific number of days using the plus or minus button.
