Programming
How Programming Works
This controller has been designed with 5 separate programs to allow
different landscape areas to have their own individual watering schedules
LA PROGRAM is a method of grouping zones (valves) with similar
watering requirements to water on the same days. These zones
will water in sequential order and on the days selected
LGroup the zones (valves) which are watering similar landscape areas
together. For example, turf, flower beds, gardens–these different
groups may require individual watering schedules, or PROGRAMS
LSet the current time and correct day of the week. If odd
or even day watering is going to be used, make sure the
current year, month and day of the month is correct
®If left unattended for over 1 minute, the LCD display will return to
AUTO no matter the position of the MAIN DIAL. If you were in
the process of programming this controller, turn dial to AUTO and
then back to the position you were programming to continue

Programming(continued)
Set Automatic Program
Set the automatic PROGRAM
for each group of zones
(valves) by completing the
following three steps:
1. Set watering START TIMES
®For each start time, all the
zones (valves) selected for
the PROGRAM will come
on in sequential order
®If two start times are
set, the zones (valves)
will come on twice
2. Set WATER DAYS
3. Set ZONE RUNTIME
(durations)
This controller has been
designed for quick intuitive
programming. Remember
these simple tips for hassle
free programming:
®One push of a button
will increment one unit
®Holding a button down will
fast scroll through units
®During the programming,
only flashing units
are able to be set
®Adjust flashing units
using or
®Press or to scroll
through settings as desired
®The MAIN DIAL is
the primary device for
selecting an operation
®Press to select different
PROGRAMS. Each push on
this button will increment
one PROGRAM number

switch to ON
4. Turn the dial to
RAINSETTINGS to
enable your rain sensor
for individual zones
