SettInG Current DAte AnD tIMe

Three items are programmed at this position:
• Time of Day and Date, the day of the week sets
automatically
• Daylight Savings time usage
• Units of measure, English or Metric
Turn the dial to the SET CURRENT DATE/ TIME position
Press the + or – button to change the value of the flashing
cursor. Hold the button down to advance rapidly over a
large range of numbers.
Press the arrow buttons to change cursor position.
Set the hour and the minutes, then advance to the AM/
PM field. Use + or – to select AM, PM, or 24 hour clock
(international, or "military" time). If 24 hour clock is
selected, Program Start Times and other controller times
will also be displayed in 24 hour format.
Press the arrow buttons to advance and set the date in
MM/DD/YY format.
ACC Daylight Saving Time has been updated for the new
USA requirements. If set to Yes, time will offset one hour
forward at 2 AM on the second Sunday in March, and reset
("fall back") on the first Sunday in November.
Units of Measure: choose English or Metric. This will set
the unit type for the entire controller.

Three items are programmed at this position:
• Overlap or Stack start time priority
• Start times for each of the six programs (A – F)
• Extended Feature: No Water Window

To Set Program Start Times

1. Turn the dial to the SET PROGRAM START TIMES
position
2. Select the Program (A – F) by pressing the Program
button
3. Press the arrow buttons to change cursor position
4. Press the + or – button to change the value of the
flashing cursor
5. Select Stack or Overlap for the Program. It is
important to know that if the setting within the Set
Program Overlap Options dial position is not set
to "Stack or Overlap," the option of selecting Stack
or Overlap (at the Start Times position) will not be
possible.
6. The copy and paste buttons may be used to speed
up programming (press the Copy button at any Start
Time position, then move to another position and
press the Paste button. The same Start Time will be
pasted there).

Stacked Start Times

Stacking means that programs are not allowed to overlap;
if one Program is set to start before another Program has
completed, it will be pushed back ("stacked") regardless
of its actual start time.
Each of the six programs (A – F) has ten start times
available, for a total of sixty available automatic starts. The
default is to stack the start times in alphanumeric order.
Program A will read Overlap, but all other programs will
read Stack. For instance, start time "Program A at 8:15
AM" would start before "Program B at 8:15 AM" because
A comes before B. The Start Time for Program B at 8:15
AM would start following the completion of Program A's
watering.

Overlapping Start Times

Overlapping start times allows more irrigation to occur
simultaneously. Overlap starts Programs at their exact
Start Times, regardless of other Programs that may be
running (it is the opposite of Stacking). All six programs
can be programmed to Overlap and thus potentially run
simultaneously. This is great when a short watering
window is necessary and the hydraulics of the system
allows for high total water flow.
