The four (4) settings on the screen determine how
much actual rainfall will be placed into the rain table,
which is used to offset irrigation run times. The
following is a description of each:
Note:
Each value in the following definitions denoted
in
red
is a default setting and can be adjusted by the
user.
•
Stop irrigation after:
This setting determines
how much rain must fall, before the controller
will start accumulating rainfall values in the rain
table. It also determines when to halt any on
going irrigation. In figure 5.10, (
0.10
) inches of
rain will have to fall before any rain data starts to
accumulate in the rain table, or irrigation is
stopped.
•
Maximum Hourly Rain:
This setting determines
the maximum amount of rain that will be put in
the rain table after a period of one (1) hour of
rain. In figure 5.10, a maximum of (
0.20
) inches
of rain will be put into the rain table, no matter
how much rain falls in a one (1) hour period. The
amount of rain from this setting put into the rain
table, will increase only until it reaches the 24
HOUR TOTAL setting.
•
Maximum 24 Hour Total:
This setting
determines the maximum amount of rain that will
be put into the rain table in a 24 hour period. In
figure 5.10, a maximum of (
0.60
) inches of rain
will be put into the table, no matter how much
rain falls in a 24 hour period. The amount of rain
from this setting put into the rain table, will
increase only until it reaches the LET RAIN
ONLY BUILD UP TO :setting.
•
Let Rain Only Build Up to:
This setting
determines the maximum amount of rain that will
be stored in the rain table. In figure 5.10, the
controller will stop storing rain data in the rain
table if the Maximum 24 Hour Total reaches
1.50
inches of rain.
