Effective Rain Settings
Main Menu
Settings Irrigation Control
Advanced Settings Effective Rain Settings
Not all rainfall measured is considered effective rain.
Rain that falls too quickly will run off before reaching
the root zone, and rain that falls when the soil is com-
pletely saturated will run off as well. The Effective Rain
settings include:
Max Hourly Rain: The Maximum Hourly Rain
is the maximum amount of rain that will be
accepted each hour in the soil moisture level.
Saturation Allowance for A and B: The
Saturation Allowance is equal to the amount of
rain it takes to saturate the soil after satisfying
the Irrigation Amount and before runoff
occurs.
Navigate the menus to the Advanced Settings screen,
and press
À on Effective Rain Settings screen. The
will be at Max Hourly Rain, press À to move the cur-
sor to the Max Hourly Rain value, and use
Œ or Õ to
adjust the value. Use à to go back to set the
Saturation Allowance for A and B. Once the
is located
at Saturation Allowance, press
À once to move the
cursor to A and twice to B. Use
Œ or Õ to adjust these
values.
Signal Crop Coefficient

Advanced Settings Signal Crop Coefficient
The WRSP includes a Signal Crop Coefficient percentage
in the weather signal. A Signal Crop Coefficient (Kc)
adjusts ET to a specific crop and can change over the year
due to seasonal conditions (ETos x Kc = ETc).
You can choose to use or ignore the Signal Crop
Coefficient. After navigating to the Signal Crop
Coefficient screen, press

The wind speed measurement included in the weather
signal can be scaled by a percentage to compensate for

Historical ET
Main Menu
Settings Irrigation Control
Advanced Settings Historical ET
The ET Manager can be set to operate using historical
ET data, instead of the weather signal data. If a prob-
lem occurs and the ET Manager is not receiving the
weather signal, it will continue to operate using histori-
cal ET data as a default ET. This setting represents an
average daily ET for each month. To obtain the average
daily historical ET for your area, go to
www.rainbird.com/etmanager and download your
Weather Reach Signal Provider Information Sheet.
From the Historical ET
screen, the cursor location
will be at January. To enter
January daily ET average,
press
À moving the cur-
sor location to the ET value.
Use
Œ or Õ to adjust the ET value, and press à to
move the cursor back to the list of months. Scroll down
to the next month and repeat the process for each month.
Your ET Manager uses the programmed daily historical
ET at the first of each month, and then looks at the next
month value to make an ET curve to determine historic
ET values for each day of the month (see Figure 10).
