Precipitation rate can be entered two ways: by sprinkler type or
by specific precipitation rate. If you do not know the specific
precipitation rate for the zone, you can select the sprinkler
type, or watering equipment used on that zone: Spray, Rotor,
Drip, or Bubbler irrigation. The SmartLine
®
controller will apply
a default precipitation
rate for the sprinkler type
selected. If you know the
specific precipitation rate
expected for the zone,
as stated by the sprinkler
manufacturer, you can
use the ▲ or ▼ arrow
buttons to scroll past the sprinkler types and select that number.
For USA users, inches per hour will be displayed (.2 to 3.0
inches per hour). For international users, the controller will dis-
play precipitation numbers in centimeters per hour. As a rule in
Auto Adjust mode, the lower the precipitation rate entered, the
longer the zone run time will be to achieve required plant life
needs.
Plant Type: This posi-
tion is used to specify
the type of plant materi-
al to be watered by
each zone as an impor-
tant component of
determining the water-
ing needs for each zone. Use the ▲ and ▼ arrow buttons to
select plant type or percent for each zone. Press NEXT and
BACK buttons to access each zone. Plant type selections are:
CTurf (cool turf like bluegrass); WTurf (warm turf like St.
Augustine); Shrubs; Annuals (floral beds); Trees; and Native
plants. The SmartLine
®
controller formula uses cool turf mowed
at 4 to 6 inches tall as the base watering number (100%) or
crop factor. The cool turf default is 80% considering average
mowing heights of 2 to 3 inches, which result in less transpira-
tion and lower water requirements. If you prefer more specific
input, you can scroll past the plant types and use % designa-
tions of 10 to 300%. For
example, a Native plant
zone might be assigned
30% rather the default
of 25%. As a rule in
Auto Adjust mode, the
higher the plant type
percentage entered, the
longer the zone run time
will be to achieve
required plant life needs.
For maximum water savings, it is recommended that your sprin-
kler system be zoned with a separate valve for each type of
plant material. If you have mixed types of plants in a single
zone, you will need to select which type of plant to use in the
determination of water
requirements.
