Connecting Other Flow Sensors; Icr Remote Control; Multiple Stations Simultaneously - Hunter ACC-1200 Manual

ConneCTInG oTher floW sensors ............................................

Some other brands or models of flow sensors may be
compatible with the ACC controller. One known-compati-
ble model is Data Industrial model IR-220B (also sold as
Hunter model GENDATFL).
NOTE: The ACC flow sensor connection is a 20 VDC pulsed
output which senses interruptions as "clicks". It is DC
voltage, and the polarity must be observed.

ICr remoTe ConTrol .................................................................

The ACC controller has an integrated SmartPort
the cabinet's upper left side, or inside the front panel of
the plastic pedestal. This connection is automatically
compatible with Hunter ICR and SRR remote receivers.
To connect: remove the weather-resistant rubber cover
(metal cabinet versions), align the remote receiver's
pins with the mating receptacle, and push firmly until
the receiver is fully seated. If the ET System adapter is
installed, plug the receiver into the mating connector on the
adapter.
If the receiver address is to be changed, hold in the green
button while plugging the receiver into the SmartPort, in
accordance with the ICR instructions.
Refer to the remote control's instructions for additional
addressing and operations. However, there are some
significant differences in operating the remotes with the
ACC controller, from previous Hunter controllers.
When a program or station is started by ICR, the ACC
display will (as always) show why the program or station is
running. Remote starts are followed by "ICR" in the display
(Fig.1).
To set up an ICR remote control for operations with ACC,
consult the ICR instructions. Use the Mode button on the
ICR transmitter to select a station size of "240" to allow
access to all ACC programs and stations. Only ICR Remotes
manufactured September 2006 or later are compatible with
ACC. If you have an older ICR remote, the maximum station
size is 48. Therefore, if you are using an older remote and
an ACC decoder controller, the highest station you will be
able to control is station 48. You must obtain a newer ICR
to operate correctly with any ACC controller.

ACC is an overlapping controller, and will allow up to
6 stations to run simultaneously. While other Hunter
controllers will stop existing stations when a new ICR
remote start command is received, the ACC will continue to
run existing stations along with the new stations, until the
maximum of 6 events has been reached (Fig. 2). If 6 events
are running and an ICR command is received to start another,
the command will be ignored. No new remote commands will
be accepted until one of the 6 events times out.

The red + terminal corresponds to the red wire on the HFS
sensor, and if connecting to other brands of sensor insure
that correct polarity is observed.
Connect the positive (+) wire to the red Flow terminal on
the Master Module, and the negative (–) wire to the black
terminal.
