Flow.
The Learn Flow
Utility has recorded
a zero (0) flow rate
for one or more
station.
Turn dial to Flow Sensor / Set Flow Rates /
View Flow Rates / View Station Rates. Check for
stations that have a 0 flow rate and are labeled
Learned.
• If all stations have learned a 0 flow check flow
sensor/ input connections, Flow Sensor config-
uration, FloZone assignments, etc.
• If only one or a few stations have learned a
0 flow rate check the valve operation (flow
control stem position, solenoid, wiring, etc.).
• If just small flow rate valves/stations (like drip
zones) have learned a 0 flow rate the flow
sensor may be too large for the lower flow
rates. Check the product technical specs for the
minimum flow rate of the flow sensor.

Alarm.
FloWatch (flow
sensing utility) has
detected a high or
low flow condition.
Turn dial to Alarms / History / Flow Alarms,
and review the posted Station and/or FloZone
(mainline) flow alarms. Note the station(s) or
FloZone(s) that were identified. If you configured
FloWatch to Diagnose & Eliminate or Alarm &
Shut Down, the problem station(s) or FloZone(s)
will be quarantined. Clear the Flow Alarms and
test the system.
• Station flow alarms – Manually turn on the
station. Turn dial to Flow Sensor / View Current
Flow. The current and expected flow rates
will be listed. Check the valve & sprinklers to
identify the issue and correct it. If sprinklers or
nozzles have been replaced, relearn the station
flow rate.
• FloZone alarms - Manually start a program.
Turn dial to Flow Sensor, View Current Flow. The
current and expected flow rates will be listed.
Check the water source(s) and mainline to
identify the issues and correct it.
• If FloZone high flow alarms are being triggered
by manual watering (QCV, manually bleeding
valves, etc.) consider using the MV Water
Window located under the Manual Watering
dial position. Configure window open and
close times, days of the week, MV(s) you want
open, and the
expected additional flow rate to allow for the
manual watering.
