PROGRAMMING INSTRUCTIONS
INTRODUCTION
This controller has been designed with 6 separate programs to allow different landscape areas to
have their own individual watering schedules. A program is a method of grouping stations (valves)
with similar watering requirements to water on the same days. These stations will water
in sequential order and on the days selected.
Group the stations (valves) which are watering similar landscape areas together.
Examples: Turf, flower beds, gardens. These different groups may require individual
watering schedules, or programs.
Plan your watering schedule completing the planner supplied at the back of this book.
Set 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.
HINT: To select a different program use the button marked .Each press will move to the next
program number. This is handy for quick reviewing of previously entered information without losing your
place in the programming cycle.
SET AUTOMATIC PROGRAM
Set the automatic program for each group of stations (valves) by completing the
following three steps:
1. Set start times
This sets the time when the watering schedule is to commence.
NOTE: For each start time, all the stations (valves) selected for the program will come
on in sequential order. If two start times are set, the stations (valves) will come on twice.
2. Set Watering Days
These are the selected days when the automatic system will be active.
3. Set Station Run Times
This sets the watering duration required for each station (valve).
