This is not a normal irrigation setting but may be useful for
some specialized applications. The ACC controller is NOT
designed to operate with true Normally Open valves.
ACC’s two Pump/Master Valve outputs (labeled on the
master module terminals as P/M1 and P/M2) are preset
to Normally Closed (NC), but either of them can be set to
Normally Open (NO).
A Normally On P/M setting means the station output is
always hot (providing 24 VAC) until an associated station
is activated, at which time the P/M output turns off.
• Start in any other dial position, hold the Information
button down, and turn the dial to Set Pump Operation.
Release the Information button.
The display will now permit selection of P/MV1 and P/MV2
settings.
To change the Normal condition of P/M outputs
Use the +/- keys to set P/M1 to NC or NO. Use the right
arrow to move to P/M2, and use +/- to change it between
NC or NO.
The Location field is only changeable in Decoder
controllers. In a decoder controller, the Location field may
be changed from “Controller” to “ADM” (decoder module).
If you select ADM as the Location, this indicates that the
Pump or Master Valve is connected to a decoder that has
been programmed to be the Pump or Master Valve decoder,
and the decoder is connected to the two-wire path.
If a P/M output is set to NO, the green light on the Master
Module for output activity is always lit, until a station with
that P/M is activated. Then the station activity light will go
out, to show the output has shut off.

ACC’s Real Time Flow Monitoring is designed to work with
Hunter HFS flow sensors. It is necessary to tell ACC what
size fitting the HFS has been installed into, so that flow can
be measured accurately for pipe size.
The ACC may also work with other standard types of flow
sensors or meters available, but additional calibration is
required. These sensors are set up under the selection
“OTHER”. One known compatible sensor is Data Industrial
Model IR-220B (also sold as Hunter model GENDATFL),
and other Data Industrial sensors with the same signal
characteristics should perform satisfactorily.
The HFS must be installed into one of the mating FCT
fittings designed for that purpose. At this time, there are
7 possible sizes ranging from 1” diameter (25 mm) to 4”
(100 mm), in two different classes of pipe, according to
the following table.

The HFS cannot read flow below the minimum rate (in
GPM/LPM) listed for the pipe size.
After connecting the flow meter according to the HFS
installation instructions, the Pipe Size must be entered
into ACC for the measurements to be accurate.
1. To calibrate flow sensor readings: Start in any other
dial position, hold the Information button down,
and turn the dial to Set Flow Monitoring. Release
the Information button to view the Flow Operation
screen.
