This unit is available in four, six and eight station
configurations.
Designed for residential and light commercial
applications, this controller has two separate schedules
with up to eight start times a day to ensure efficient
watering of different garden or turf areas.
These different areas may require individual watering
schedules and often use different types of sprinklers.
Examples: Turf areas generally use pop-up sprinklers
and require less frequent but heavier watering. However,
flower beds use micro sprays and require more frequent
watering. The valves (stations) which water similar
garden areas are often grouped together and put into the
same program as they need to be watered on the same
days.
These stations (valves) will water in sequential order
from the lowest number at the start time (or times)
nominated and on the days selected. Maximum watering
duration for a station (valve) is 12 hours and 59 minutes.
This controller has a 7 day watering schedule with
individual day selection per program or a 365 calendar
for Odd/Even day watering or selectable interval watering
schedules from everyday to every 15th day.
A key feature of this controller is the water saver feature
which allows quick adjustment of the station watering
times by percentages as the seasons change.
