Special Functions
Rain Delay
The Rain Delay feature (for use when a weather sensor is not installed)
enables automatic watering operation to be suspended for a period of 1
to 9 days; then resume watering automatically as scheduled.
1. Place the Function switch in the Set Programs position.
2. Turn the Dial to the Skip Days - Special Functions position.
3. Press the Manual button (repeatedly) to display rd0
(Rain Delay = 0 days).
4. Press the / buttons to select a Rain Delay period of 1 to 9
days.
5. Return the Dial to the Current Time position.
6. Return the Function switch to the Run position.
Note: When the Rain Delay function is active, the display will alter-
nately indicate the current time of day and the number of days
remaining until automatic operation resumes. To cancel Rain Delay at
any time, decrease Rain Delay setting to 0 days.
Water Budget
The Water Budget feature enables the run time of all stations, assigned
to a specific Program, to be simultaneously adjusted up or down by
percentage. From the baseline of 100%, run times can be reduced to 0%
(Off) or increased up to 200%.
To help prevent runoff when selecting a Water Budget value above 100%,
the adjusted run time is automatically cut in half, and the watering cycle
is run twice. For example, increasing the Water Budget to 160% would
first increase a 10-minute station run time to 16 minutes. However, the
station will run for 8 minutes in two consecutive watering cycles.
All zone run times are retained in the timer memory and returned to
their set value when the season adjust is reset to 100%. The only time a
station run time will appear changed is during operation.
For additional control, a Water Budget factor can be assigned universally
to a Program, or applied to a Program by specific months of the year –
when Water Budgeting by seasonal demand is preferred.
Note: Each Program is limited to one Water Budget method at a time.
Applying a Water Budget by monthly demand will override a basic Water
