Irritrol Total Control-R Series - Manual (Page 15)

13
Note: The Total Control will operate one watering cycle in a program
at a time. If a start time occurs while a watering cycle is in progress,
the start time will be delayed until the previous cycle is finished (this
is called “start time stacking”). If the watering cycle extends past
midnight into the next day, the cycle will continue operating until
finished. However, if a watering cycle has been delayed until after
midnight into a non-watering day, the watering cycle will not occur.
SELECTING THE DAYS TO WATER
Several watering day scheduling options are available. Each watering
program can utilize any ONE of the following schedules:
• Days of the week
Use this type of schedule to water on specific days of the week. The
days are displayed as three-letter abbreviations. For example, Sunday is
SUN , Monday is MON , etc. Only the days you select to water will
remain on the display.
• Odd Days or Even Days
To select every odd or even number calendar day, use this option.
Because the 31st and the 1st are both odd number days, the 31st is
automatically removed from the schedule. This watering day option
also enables selected days of the week to be removed from the
schedule.
• Day Interval
Selecting watering days by Day Interval enables a specific number of
days between watering to be selected. For example, selecting a 1-day
Interval schedules watering for every day. A 2-day interval schedules
watering for every other day. A 30-day interval is the maximum
interval frequency, which provides watering once every 30 days.
Another setting within the Day Interval is the current day of the
schedule. The current day (displayed as
TODAY ) can be set for any day
within the interval. This number automatically increases by one every
day. When the
TODAY
number equals the Day Interval number, a
watering day will occur. For example, to water every third day starting
today, a 3-day interval would be set with
TODAY as day 3. Or, to water
every 5 days starting tomorrow, a 5-day interval would be selected with
TODAY as day 4.
