PRODUCT FEATURES AND BENEFITS
per station, plus a master valve. This means
up to 4 valves and a pump start relay or mas-
ter valve can be operated at the same time.
Non-volatile Memory
Holds programs indefinitely; excellent
insurance against unreliable power
The ICC has what every user of electronic
controllers has wished for: the ability to keep
all programs in memory without a backup
battery. In the event of a power failure or if
AC power is suspended from the controller
by the user, the ICCʼs non-volatile memory
will maintain programs forever, without
need for a battery. Normal watering will
resume when AC power is restored.
Superior Surge Protection
All microcircuits are protected from
electrical spikes/lightning
The ICC is equipped with electronic compo-
nents called MOVs (Metal-Oxide Varistor).
These MOVs are designed to shunt electrical
surges away from microcircuits through the
controllerʼs grounding circuit. The ICC uses
these MOVs to protect the controller from
minor power surges coming in through the
primary (110/230VAC) input side and also
the secondary output side (24VAC).
Self-Diagnostic Electronic
Short Circuit Protection
No fuses to worry about; only faulty
stations stop watering
The ICC automatically skips shorted stations
allowing the rest of the system to operate as
normal. The self-diagnostic electronic short
circuit protection system is very beneficial to
the user because of its ability to aid in identi-
fying field wiring problems. It is almost
as if the controller can troubleshoot the
system itself.
The self-diagnostic system detects a high
current path–a "short"– through an operat-
4
(continued)
ing station (the most common causes of
shorts are faulty solenoids or when a bare
valve common wire touches a bare station
control wire). When a short circuit is
detected on a station, instead of blowing a
fuse which would shut down the entire
irrigation system, the controller will skip
over that station and continue to water the
rest of the zones in the program. The con-
troller will indicate what zone is shorting
by showing the station number followed by
ERR in the LCD display. The controller will
continue to "jump over" that zone during
every watering until the zone is repaired. To
remove the ERR message from the display,
just turn the dial or push any button.
Hunter Quick Check
™
Quickly diagnose field wiring problems
The ICC also provides irrigation profes-
sionals with the ability to efficiently and
effectively diagnose problems in the field.
Instead of having to physically check each
field wiring circuit for potential problems,
the user can run the Hunter Quick Check
circuit test procedure. This circuit diagnostic
is very beneficial because of its ability to
aid in quickly identifying "shorts" in control
wiring.
Programmable Delay Between Stations
Slow closing valves and well recovery will
never be an issue
A programmable delay between stations
solves the problem of slow closing valves
because of a hydraulic overload condi-
tion. The delay also solves the problem of a
system operating off of a slow filling well,
allowing the well to recover between zones.
The ICCʼs programming will allow it to fit
into any situation where a delay is neces-
sary, as the delay is programmable up to
