ET Manager Series - Installation and Operation Manual 47
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.
Note: A Historical ET database is available in your Rain
Bird ET Manager Scheduler program found on the pro-
vided CD.
System Settings
Your ET Manager System Settings establishes the
source of the weather signal information, how your ET
Manager interacts with your sprinkler controller, and
other valuable tools. The System Settings details are
discussed in chapter 3, Programming.
Your ET Manager System Settings include:
• Data Source: The Data Source settings consist
of specific settings programmed to access the
appropriate weather signal.
• Options: Option settings allow you to program
the units used (English or Metric) and a securi-
ty password.
• Output Method: The ET Manager can utilize
four Output Methods. In most cases, the
“Enable” Output Method is the standard
method.
When conducting the site assessment, your ET
Manager System Settings may have been previously
programmed. By documenting these settings, you will
be able to verify the settings have been programmed
correctly.
ET Manager Scheduler
The Rain Bird ET Manager Scheduler software program,
included with your ET Manager, was developed to gen-
erate accurate watering schedules. The ET Manager
Scheduler uses site-specific information to help you
prepare a watering schedule that can be programmed
in your sprinkler controller. The ET Manager Scheduler
also determines the initial settings for your ET
Manager. We encourage using this program for making
ET Manager and sprinkler controller programming
decisions. The ET Manager Scheduler Operation Guide
is available from the CD included with your ET
Manager.
