Adjust Water Budget Percent

The Water Budget feature on the ESP lets you increase or
decrease the run times of all stations by a selected per-
centage. You may adjust the run times as low as 10 per-
cent and as high as 200 percent. Adjustments must be
made in increments of 10 percentage points.

The percentages are calculated on the normal pro-
grammed run times for each station. For example, if a sta-
tion is programmed to run for 10 minutes, and you set the
water budget percent to 80%, the station will run for 8 min-
utes (80% of 10 minutes). If you set the water budget to
120%, that same station will run for 12 minutes (120% of
10 minutes).

The water budget feature can be useful for cutting back
watering during cool winter months, or for increasing wa-
tering during periods of unusual heat. Keep in mind that
the percentage you set applies to 

all 

stations on 

both

 pro-

grams.

Œ

 Turn the dial to ADJUST WATER %.

The display shows the current water budget setting

(between 10% and 200%). A setting of 100% means
that all stations will run according to their normal pro-
grammed run times.

Ž

Press  

ñ

  or  

ò

  to increase or decrease the percentage

in 10-point increments.

When water budgeting is set above or below 100 percent,

top of the display.

To turn off water budgeting, repeat steps 1 to 3, and set
the percentage to 100%.

the stations in the program, press MAN START / ADV.
