Set Water Budget per Program
Step 1 – Place the Function Dial to the SET PROGRAM position.
Step 2 – Enter the program number (1–8) being modified. Press the to activate the selection.
Press the button to clear any “Key Entry Error”.
Step 3 – Press the button.
Step 4 – Enter the desired water budget percentage for the selected program. You can decrease the program’s watering
to 0% (no watering) or increase it up to 200%. Press the button to accept the water budget modification.
Example: Increase Program 1’s watering budget to 150%. Press the button and enter to set
budget at 150%. Press to accept.
Step 5 – Repeat steps 2–4 to modify additional program water budgets.
The Monthly percent adjustment and the water budget percentage will multiply together to get the net
increase or decrease of the watering cycle.
Example: Station 1 of Program 1 has a normal runtime of 5 minutes. If the program water budget is set at
200% then the adjusted run time will be 10 minutes (5 min X 2 = 10 min). If the Monthly Adjustment is also
set at 200% for the current month, then the adjusted run time will be 20 minutes (5 min X 2 X 2 = 20 min).
Step 6 – Return the Function dial to AUTO/RUN position to exit SET PROGRAM.
CAUTION: Increasing either the program water budget or the monthly water budget percentage may shift station
operations to past midnight. During start time review, an asterisk will be displayed alerting you to the situation. The
controller will complete programs that start before midnight and end after midnight. However, program start times that
have been shifted past midnight (after day change) may be lost. Check your start times and adjust accordingly.
