Water Budget/Rain Delay
NOTE
: This option provides advanced control of the irrigation, and is not required for the
controller to operate.
Water Budget (seasonal adjustment) and rain delay allow you to adjust the timer zones
(programs A, B, C, and D) for seasonal changes and rain.
Water Budget
is a seasonal adjustment that changes the run times of all timer zones as
a percentage. For example, if the controller is set in the spring during the summer
months of June, July, and August the user might set the water budget for those months
at 150%. Meaning the zone run times will be 1.5 times the programmed duration. If the
zones were watering for 10 minutes they will all run for 15 minutes during those months.
Another example would be setting the controller in the summer and changing the water
budget for the cooler fall months of September and October to run at 50%. Meaning the
zone run times will number of zones that you want to water simultaneously under the
Acclima Flow Management System. The acceptable range is 1 to 4.

4. Repeat steps 1, 2 & 3 for each month and for each timer program.
Rain Delay
allows you to stop all timer programs during rain. For example, if rain is in the
forecast for the next three days you can easily set the SC24/36 to stop watering timer
programs (programs A, B, C, and D) for those three days.
Press the
Next
button to move to Rain Delay and press the
+
or
-
Adjust Value
buttons
to set the number of days to delay watering.
NOTE
: Water Budget and Rain Delay only apply to timed programs (A, B, C, and D).
Sensor programs take care of themselves by sensing the soil moisture levels. There is no
need to make seasonal or rain delay adjustments to sensor programs.
Glossary
Automatic circuit protection
A built-in circuit protection circuit designed to prevent damaged to the controller caused
by a faulty valve solenoid or pump start relay. The instant an overload current condition is
detected, the affected zone is turned OFF and the next zone in the watering sequence is
turned ON.
Calendar Schedule
A Calendar Schedule enables you to select specific days of the week to water, for
example, Monday, Wednesday and Friday. This is a 14 day schedule which starts on
