The SVC controller uses a numbered seven-day calendar to schedule the days to water. The display will show the days of the week as numbers 1–7.
When programming the current time and day, you can select a number to represent the current day of the week. The number can be changed to represent the user's preference. Many people think of Sunday as day 1 while others think of Monday as day 1. The day number can be set to whatever works best for you.
