Seasonal Adjust (SA)

The Seasonal Adjust feature is the easiest

way to increase or decrease the duration

times of all stations on a program. You can

use Seasonal Adjust to decrease watering

during cool winter months, or to increase

watering during hot, dry periods.

You can set the Seasonal Adjust percentage

from 10% to 200% in increments of 10%.

Changing the percentage affects all stations

on all programs (A, B and C).

Seasonal Adjust percentages are calculated

on the normal programmed duration time for

each station. For example, if a station is

programmed to run for 10 minutes, and you

set the (SA) to 80%, the station will only run

for 8 minutes (80% of 10 minutes). If you set

the (SA) to 120%, that same station will run

for 12 minutes (120% of 10 minutes).

NOTES: (SA) will not split a minute.

One whole minute is the lowest

duration time allowed.

All duration times for every

programmed station will be

increased or decreased when you

use the (SA) feature.
