ET Manager Series - Installation and Operation Manual 77
Rain Interrupt 24 Hours: Rainfall over the last 24
hours that is at or above the Rain Interrupt 24 Hour set-
ting will cause a Weather Interrupt. The weather inter-
rupt is cancelled once the total rainfall in the last 24
hours drops below the Rain 24 Hour setting.
Rain Interrupt 1 Hour: Rainfall over the last hour that
is at or above the Rain Interrupt 1 Hour setting will
cause a rain interrupt. The weather interrupt is can-
celled once the total rainfall in the last hour drops
below the Rain 1 Hour setting.
Rain Region: Like the weather region number, a rain
region number represents an area where customers
share data. Within an area, one on-site tipping bucket
rain gauge is used to share localized rain data among
ET Manager customers, allowing for a more accurate
representation of local rain. Your Weather Reach Signal
Provider (WRSP) broadcasts rain region data.
Rain Source: The rain source is the source of rain data
for the ET Manager. Rain data comes from the weather
signal, from an optional rain gauge, or from a rain
region.
Rain Tip Input Failure: Your ET Manager can use real-
time rain data collected from an optional on-site rain
gauge. If you are using a rain gauge to collect rain data
and “Rain Tip Input Failure” appears on the Home
screen, your ET Manager is indicating a problem with
the Rain Tip wire terminal, installation, or operation of
the on-site rain gauge.
Restore Defaults: If ET Manager’s programmed set-
tings have been saved as default settings, and the cur-
rent settings are changed, by restoring defaults the orig-
inal saved default settings are restored. If settings were
not saved as defaults, restoring defaults restores the fac-
tory default settings.
Root Depth: The soil reservoir capacity is directly relat-
ed to plant root depth. Deeper roots increase the
amount of water available to the plants. To promote a
deep healthy root system, best horticultural practices
recommend less frequent, deep watering. Use a shovel
or soil probe to determine root depth.
Saturation Allowance: The amount of rain it takes to
saturate the soil after satisfying the Irrigation Amount
before run-off occurs. Unique Saturation Allowance
settings can be made for Valve Group A and Valve
Group B, and are typically programmed as half the
Irrigation Amount.
Save Defaults: The current ET Manager settings can be
saved. Once saved, you can restore saved settings if set-
tings have been changed incorrectly by using Restore
Defaults.
Serial Number: The serial number of your ET Manager
is displayed on the LCD contrast screen and is visible
under the terminal cover on the left side of your ET
Manager.
Set Signal Provider Code: If the attention message,
“Set Signal Provider Code” appears on the Home
screen, your ET Manager has been installed, but not
programmed with the appropriate Signal Provider
Code. The Signal Provider Codes can be accessed from
www.rainbird.com/etmanager and the ET Manager
Scheduler.
Signal Crop Coefficient (or Signal Kc): Crop coeffi-
cients are used to modify ET to meet the specific needs
of the landscape
.
The Weather Reach Signal Provider
(WRSP) includes a crop coefficient value in the weather
signal. You can decide to “Use” or “Ignore” this adjust-
ed value to adjust ET in the Advanced Settings in
Irrigation Control.
Signal Provider Code: Your ET Manager must be pro-
grammed to receive information from your specific
Weather Reach Signal Provider (WRSP). A Signal
Provider Code is unique for your WRSP and is neces-
sary for your ET Manager to receive a weather signal.
The code consists of 10 different numbers and these 10
numbers are labeled A-J. The Signal Provider Codes
can be accessed from www.rainbird.com and the ET
Manager Scheduler program.
Site Assessment: A site assessment should be complet-
ed to determine site-specific conditions which affect
programmable settings in ET Manager and sprinkler
controller.
