2. Lower the Max Hourly Rain setting for Valve
Group A or B. The Maximum Hourly Rain set-
ting may be limiting the amount of rainfall
applied to the Moisture Levels. Change the
Maximum Hourly Rain to a lower amount to
allow the ET Manager to limit rainfall in the
Moisture Levels for Valve Group A or B.

3. The Saturation Allowance for A or B may be too
high. Lower the Saturation Allowance settings
for Valve Groups A or B. The Saturation
Allowances for A and B create a limit to the
amount of rain that can accumulate in the
Moisture Levels. The ET Manager uses this
amount to limit the total amount of rain that
can accumulate in the Moisture Level.

rectly represent rainfall at your site. Connect

3. Program a 1 Hour Rain Interrupt to interrupt
watering until rain accumulations reach below
the programmed Rain1 Hour setting. See
chapter 3, Programming, for more information.
Main Menu
Settings Weather Interrupt
Rain 1 Hour Rain
4. Program a 24 Hour Rain Interrupt to interrupt
watering until rain accumulations reach below
the programmed Rain 24 Hour setting. See
chapter 3, Programming, for more information.
Main Menu
Settings Weather Interrupt
Rain 24 Hour Rain
Note: Remember that small amounts of rainfall
may not be enough to warrant a 1 Hour or 24
Hour Rain Interrupt.
Note: If the Moisture Level for Valve Group A or B
is equal to zero at the opening of the Automatic
Window, sprinkling will remain enabled through-
out the Automatic Window unless 1 Hour or 24
Hour Rain Interrupts are programmed. Rain that
falls during normal watering cycle will be account-
ed for in the Moisture Levels for Valve Group A and
B.
Rain Bird Note: New models of the Rain Bird ESP
controller family offer a “RASTER” test, which is
used to diagnose electrical problems with the
sprinkler system. Before executing the RASTER
test press the Override button on the ET Manger
to enable the controller common.
