Adjust Water Budget
DIAGRAM 20 & 21
Adjusting the Water Budget feature is the easiest way to
increase or decrease the run times of all stations on a program.
You can use Water Budget to decrease watering during cool
winter months, or to increase watering during hot, dry periods.
You can set the Water Budget percentage from 10% to 200%
(all station run times doubled), in increments of 10%.
Changing the Water Budget percentage affects all stations
on all three programs (A, B, and C).
Water Budget percentages are calculated on the normal
programmed run time for each station. For example, if a station
is programmed to run for 10 minutes, and you set the Water
Budget to 80%, the station will only run for 8 minutes (80% of
10 minutes). If you set the Water Budget to 120%, that same
station will run for 12 minutes (120% of 10 minutes).
NOTE: Water Budget will not split a minute. One
whole minute is the lowest run time allowed.
1. Turn the programming dial to WATER BUDGET.
2. The number 100 appears in the display. This indicates
that all stations are running at 100% of their programmed
watering time.
