ADVANCED PROGRAMMING
Seasonal Adjust %
The seasonal adjustment feature lets you scale the run times of all
valves up or down by a selected percentage. You can set the
percentage from 0% to 300%, in increments of one percent. The
normal programmed run time is 100%.
You can set the percentage to affect:
All valves on an individual program (see page 26)
All valves by month (see page 27)
You can use the seasonal adjustment feature to cut back watering
during cool winter months, or to increase watering during periods
of unusual heat. In addition, you can use the 0% setting to shut off a
program temporarily.
Seasonal adjustment percentages are applied to the normal
programmed run times for each valve. For example, if a valve is
programmed to run for 10 minutes (100%), and you set the seasonal
adjustment to 80%, the valve will run for 8 minutes (80% of 10). If
you set the seasonal adjustment to 120%, that same valve will run
for 12 minutes (120% of 10).
Seasonal adjustments you make by program and by month will be
multiplied together to calculate a run time for the valve.
For example, assume a valve on Program A is programmed to run
for 10 minutes (100%). Then you set a seasonal adjustment for
Program A of 80%. Finally, you set a monthly adjustment for
January of 50%. The adjusted run time for the valve in January is as
follows:
