If Daylight Savings is set to USE, the time will change forward one
hour at 2 AM on the last Sunday in March, and will change backward
one hour at 2 AM on the last Sunday in October.
When the Controller Type settings are complete, turn the dial to
save the information. For initial setup, proceed to the Plant Type
dial position.
Individual Zone Setup
Once the general setup settings have been made, it is necessary to
enter the characteristics of each station, or zone, of irrigation in the
ET Module.
The 3 dial positions Plant Type, Site Info, and Sprinkler Type need to
be completed for each zone. This may be done one of two ways:
1) Go to each dial position and advance through all stations. Enter
the Plant Types for each station, turn to Site Info and advance
through all stations again, and finally turn to the Sprinkler Type
position and repeat for all stations.
2) It is easier for some to set all characteristics for each zone, one at
a time. ET System will stay on the same selected station through
all 3 dial positions, so you can select a station and choose the
Plant Type, turn to Site Info and enter the slope, soil, and sun
data, then turn to Sprinkler Type and set the precipitation rate.
Select the next station and repeat, until all stations have all data.
Multiple Plant Types Per Zone:
Occasionally a single zone of irrigation will water several different
types of plants. This is not ideal, but the correct approach in this
case is to set all characteristics for the most sensitive (to watering)
plant species in the zone. If one of the species is highly susceptible
to under- or over watering, use that plant’s characteristics for all zone
setup information.
The “zone” is the minimum level at which automatic irrigation control
is possible. If damage to valuable landscaping or specimen plantings
is feared, do not include the station in the ET setup at all, or physically
add an additional zone to the system.
Plant Type
At the Plant Type dial position, select and customize the actual plants
irrigated by each zone of irrigation. There is one screen for each zone
(if there is more than one plant type within a zone, select the type
most sensitive to watering).
STATION 01
MATURITY: ESTABLISHED
TYPE: GRASS
VARIETY: FESCUE
Set all information for one zone (or station), then advance to the next
station with the Station button on the ET Module.
Use the right arrow key to advance through the fields, and the +/- but-
tons to scroll through all possible selections.
Maturity
There are only two maturity settings for all plant types, NEW or
ESTABLISHED.
Established indicates normal watering requirements for turf or plants.
New indicates adjusted watering for the higher needs of growing
plants which do not yet have established root zones. The New setting
will automatically change to “Established” after a preset period of
days, depending on the Plant Type selected.
If a plant type is entered as “New”, the starting crop coefficient will
“mature” over time to an established plant crop coefficient based on
the plant type:
• Grass: 42 days (6 weeks)
• Shrub: 3 months
• Tree: 7 months
• Annual/Perennial/Biennial: 30 days
• Native/Desert: 6 weeks
The setting can also be changed manually at any time.
