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

• Let Rain Only Build Up to: This setting
determines the maximum amount of rain that will

You have the option of enabling or disabling the use
of rain (negative hold over) for any of the controller’s
seven programs. If you select YES, rain (negative
hold over) will be used for that program to reduce
irrigation run times. If you select NO, rain will have
no effect on irrigation run times for that program.
If there is no rain bucket installed and you are not
sharing rain data through the Calsense Command
CENTER program, these settings will have no effect
on irrigation.
Note:
Negative Hold-over is time subtracted from
station run times. This is caused when user set rain
parameters are crossed.
