4. For non-Hunter flow sensors, Custom 1, Custom 2, or Custom 3 (Metal
Version I-Core) can be selected as a flow sensor type. With custom
selected, press the ► button to program the K-Factor and Offset that is
specific to that sensor, specified by the flow sensor manufacturer.
Use the ▲or ▼ buttons and the ◄ or ► buttons to navigate through
5.
the Custom, K-Factor, and Offset screen. Once you navigate to a
particular number and it starts flashing, the number may be changed,
press the + / – button to either increase or decrease the value. Once
you have completed entering the K-Factor and Offset specified by
the manufacturer of the flow sensor, use the ▼ button to return to the
main Sensor Configuration screen.
Use the ◄ button to return to the advanced features main screen, or
6.
move the dial from adVanCed feaTures and simply return the dial
back to Advanced Features. Use the ▼ button to move the ► cursor
next to Flow Operation, press the + button.
7. The display will show Station 1 Flow Monitored and a flashing NO.
A selection of NO will indicate that this station's flow will NOT be
monitored. Press the + button, and the value will change to YES.
This selection will allow for this station's flow to be monitored. If flow
monitoring is enabled (Yes), a new screen will appear with important
characteristics of each stations monitored flow. Use the ◄ or ►
buttons to scroll through the station numbers and assign YES or NO
for the stations flow monitoring.
Turn the dial to Manual OperaTIOn. Use the ▼ button to move
8.
the ► cursor next to learn expected flow, press the + button.
9. If you would like to learn the flow for All Stations, simply turn the
dial to RUN. The controller will learn all the stations that have been
programmed for their flows to be monitored, and have programmed
run times. The learning process will actually activate each station
automatically, operating each station approximately one minute
to learn the flow rate. Once all the stations have been learned,
the controller will return to its automatic programming and flow
monitoring will be active.

The Learn Expected Flow display will also indicate if there is a problem with
any programming. If station run times were not programmed in the set
station run Times screen, the controller will display no runtime in the
learn expected flow screen.
If no stations were set to have their flows monitored in the Flow Operation
section of Advanced Features, the controller will display no flow station as
well as no runtime in the learn expected flow screen.
If no HFS FCT size was programmed in the Sensor Configuration section of
Advanced Features, the controller will display no flow sensor in the learn
expected flow screen.
Once flow monitoring has been established, the rules that apply to an
overflow or underflow condition are very important to understand. There
is a diagnostic testing procedure the controller will activate to determine
if there is an overflow or underflow condition. A complete description of
the process is explained in the Controller Diagnostics and Troubleshooting
section under System Status Dashboard, Flow. It is important to read this
section in order to understand the flow monitoring process.
