Use the (L) knob to select Odd or Even days.
Interval: When Interval is selected, turn the (U) knob to
WATER DAY INTERVAL. Use the (L) knob to set the day
interval. Day intervals can be set from 1 to 31 days.
Days of Week: Uses a 7-day calendar Sunday through
Saturday. Use the (U) knob to move through each day of
the week. Use the (L) knob to turn days o or on. (O
days shown as a dash“—“).
Days of Week by Month: Uses a 7-day calendar Sunday
through Saturday for each month of the year. Turn the (U)
knob to Jan OK TO WATER ON. Use the (U) knob to move
through each day of the week. Use the (L) knob to turn

Follow the above procedure for each month of the year.
O: When O is selected, the controller will ignore
programmed starts for the selected program until a
dierent water-day mode is selected.
Stations
Individual stations are assigned to a program (start time(s), water
window and water day mode), and station mode. There are four
station modes to select from: Automated by WeatherTRAK, User w/
ET, User No ET and O. Select the station mode based on the type of
landscape (new vs. existing) to be irrigated.
Note: The same station cannot be assigned to dierent
programs.
Programming for Existing Landscapes
2.5 Automated by WeatherTRAK
Automatically calculates run times, cycle and soaks for each zone
based on zone-specic attributes. Daily ET updates then adjust
the calculated run times to reect current weather conditions.
Run times will vary as weather changes.
Note: To navigate through the next several screens, use
the (U) knob to move to each underlined heading and
the (L) to select a choice within each function.
Select Station: Locate the station to be programmed.
Select Station Mode: Select Automated by WeatherTRAK.
Note: To Preview abbreviated Auto mode station settings
for this specic station, press and hold the * button.
Select a Program: Assign the station to a program that has a
start time and water day mode.
Use Water Window: If this station can irrigate outside of the
water window, select “No”.
Usable Rainfall: If a station is under a roof, heavy tree canopy
or semi-porous roof, select either “None”or a percent of rainfall
that is actually used. When “None”is selected, the specic
station will water during Rain Pause.
Sprinkler Type: Select 1 of 13 industry-recognized sprinkler
types. When a sprinkler type is selected, a default precipitation
rate and sprinkler eciency value is automatically assigned.
Both values can be changed in the next two screens if dierent
than the displayed default rates.
Precipitation Rate: Is how much is applied in Inches per Hour.
Changing the precip rate will change run times. Lower Precip
rates = high run times, Higher Precip rates = lower run times.
Sprinkler Eciency: Every sprinkler applies water with a
specic eciency based on its design and performance and
spacing. If head or row spacing is stretched, eciency is less.
(Higher = less water; Lower = more water).
Soil Type: Select 1 of 5 soil types determined by the USDA.
Plant Type: Select 1 of 17 plant types that best represents the
valve zone being irrigated.
Root Depth: Turn the (U) knob to ROOT DEPTH. Turn the
(L) knob to select root depth. (Shallow roots = more frequent
watering; deep roots = less frequent watering.)
Sun Exposure: Select 1 of 4 levels of sun exposure of the valve
zone being irrigated.
Slope: Select 1 of 5 slope gradients. The steeper the slope the
higher number of cycles will be applied.
Sprinkler Location on Slope: Select 1 of 5 choices identifying
sprinkler locations on a slope.
Next Station: Turn the (U) knob to go to the next station or use
COPY to duplicate settings to like stations.
2.6 User With ET
Set run times, number of cycles and the soaks between cycles.
It then automatically increases or decreases runtime based on
the daily weather information dened as ET.
Select Station: Locate the station to be programmed.
Select Station Mode: Select User w/ ET
Select a Program: Assign station to a program (with a start
time, water window and water day mode).
Use Water Window: If this station can irrigate outside of the
water window, select “No”.
Usable Rainfall: If a station is under a roof, heavy tree canopy
or semi-porous roof, select either “None” or a percent of rainfall
that is actually used. When “None”is selected, the specic
station will water during Rain Pause.
Set Runtime: Set a desired run time.
Set Number of Cycles and the Soak Time: Select from 1-20
cycles and Soak times from 0 to 480 minutes in 10 minute
increments.
Reference ET: Set a reference ET that is appropriate for the
schedule just set. The number you see in parenthesis is ET
for the past week and is the value to enter as Part 1 and 2.
Alternately, you can set the program you would run in July and
use a weekly reference ET that is normal for your area in July.
Other Stations: Repeat these steps for other stations assigned
to this station mode.
