INSTRUCTION MANUAL

IRRIGATION CONTROLLER4, 6 or 8 station models available.

This unit is available in four, six and eight stationconfigurations.Designed for residential and light commercialapplications, this controller has four separate scheduleswith up to sixteen start times a day to ensure efficientwatering of different garden or turf areas.

These different areas may require individual wateringschedules and often use different types of sprinklers.

Examples: Turf areas generally use pop-up sprinklersand require less frequent but heavier watering. However,flower beds use micro sprays and require more frequentwatering. The valves (stations) which water similargarden areas are often grouped together and put into thesame program as they need to be watered on the samedays.

These stations (valves) will water in sequential orderfrom the lowest number at the start time (or times)nominated and on the days selected. Maximum wateringduration for a station (valve) is 12 hours and 59 minutes.

This controller has a 7 day watering schedule withindividual day selection per program or a 365 calendarfor Odd/Even day watering or selectable interval wateringschedules from everyday to every 15th day.

A key feature of this controller is the water saver featurewhich allows quick adjustment of the station wateringtimes by percentages as the seasons change.

Programming InstructionsIntroductionThis controller has been designed with four separateprograms to allow the different garden areas to have theirown individual watering schedules.

A program is basically a method of grouping stations(valves) with similar watering requirements to water onthe same days. These stations will water in sequentialorder from the lowest number at the start time nominatedand on the days selected.

The important elements of programming yourcontroller are:

l Group the stations (valves) which are watering similargarden areas together.

Examples: Turf, flower beds, pergola areas, vegetables.These different groups may require individual wateringschedules.

l Plan your watering schedule completing the plannersupplied at the back of this book.

l Set the current time and correct day of the week.

l Set the automatic program for each group of valvesby completing the following 3 steps.

1. Set Starts.

This sets the time when the watering schedule is tocommence. Note: For each start time, all the valvesselected for the program will come on in sequentialorder. If two start times are set, the valves willcome on twice.

2. Set Watering Days.

These are the nominated days when the automaticsystem will be active.

3. Set Station Run Times.

This sets the watering duration required for eachstation (valve).
