Setting the Precipitation Rate

!
Important:
The sprinkler precipitation rate (PR) is a key factor in the calcula-
tion of an automatic watering program. If you know the actual
PR value, enter it at this time. If you do not have this information,
a default value, based on the sprinkler type entered in the
previous step, will be automatically entered by the controller.
Note: For additional information regarding PR value calulation
methods, see "Gathering Site Data" on page 79.
1. Within the Program menu, turn the Upper Line knob to view
the following display:
PRECIP PART 1
1.70 Inches/Hr
2. The default PR value will be displayed for the sprinkler type
selected. The whole number is selected by default. Turn the
Lower Line knob to adjust the value from 0 – 9.
Note: The PR value is adjustable from 0.10 – 9.90. The whole
number value is only adjustable to 0 when the decimal number
value is .10 or higher.
3. Turn the Upper Line knob right one stop to select the decimal
number.
4. Turn the Lower Line knob to adjust the decimal number value.
Setting the Efficiency Value
Like the sprinkler's PR, the Efficiency value is a key factor required
by the controller's scheduling engine to calculate an efficient watering
program for each station. The controller will automatically enter an
Efficiency value based on the type of sprinkler selected for the station.
Changing the Efficiency value will alter overall station watering
operation as follows:
• Increasing the Efficiency value (sprinkler efficiency is higher
than normal) decreases overall watering.
• Decreasing the Efficiency value (sprinkler efficiency is lower
than normal) increases overall watering.
