Flow Operations
FLOW LIMITS
In the Flow Zones menu, press the so key for Flow Limits.
Maximum Flow: This sets the highest possible ow rate
allowed in the Flow Zone for any reason. This should be
considerably larger than the maximum ow allowed in normal
irrigation (so that it does not alarm before station-level
diagnostics can be performed). When the ow sensor detects
a ow higher than this, the irrigation will be shut down.
Unscheduled Flow: This is the maximum amount of ow
allowed when no stations are actively running. This is only
to allow manual watering by hand when the controller is
not watering automatically. When the rate is exceeded, the
controller will alarm.
If Unscheduled Flow is set to OFF, the controller will not
respond to unscheduled ow.
Flow Alarm Delays: This sets an amount of time before the
Max or Unscheduled ow rates will cause an alarm, and sets
how long the Flow Zone will be shut down.
Alarm Delay: High ows will alarm immediately if this is set to
None, or they will be ignored until they have lasted as long as
the time entered here. Set in M:SS format; the longest delay
is 9 minutes, 59 seconds. This can eliminate false alarms from
temporary surges in ow.
This delay should be longer than the delays for the stations
attached to the Flow Zone.
Alarm Clear Delay: This sets the amount of time a Flow
Zone will remain shut down before allowing new automatic
irrigation attempts. Set in HH:MM format, the longest delay
setting is 23 hours, 59 minutes.
If Alarm Clear Delay is set to Manual Only, automatic
irrigation will never resume aer a high ow or unscheduled
ow alarm, until it is manually cleared by an operator at the
controller. The operator must dial to the Flow menu, select
Clear Flow Alarms, the Flow Alarms that should be cleared,
and click Clear Selected.
FLOW ALLOWANCES
In the Flow Zones menu, press the so key for Allowances.
Watering Budget: Enter the total amount of ow that can be
allowed in this Flow Zone in the calendar month. If the total
ow exceeds the monthly budget, an alarm message will
appear on the screen. The controller will not automatically
stop watering when this alarm occurs.
Manual Watering Allowance: This sets an additional ow
rate amount allowed for manual irrigation. This is added to
all other limits in the controller and prevents alarms from
occurring until the expected ow — plus the amount entered
here — is exceeded.
