Pro-C Controller
Large LCD Display…
Easy to read for schedule review and entry
The large LCD display simplies pro-
gramming, making it easy to read and
verify. In low light conditions, a large dis-
play is a welcome sight to any user.
Non-volatile Memory…
Holds programs indenitely; excellent
insurance against unreliable power
The Pro-C has what every user of elec-
tronic controllers has wished for: the abil-
ity to keep all programs in memory with-
out a backup battery. In the event of a
power failure or if AC power is suspended
from the controller by the user, the Pro-C’s
non-volatile memory will maintain pro-
grams forever, without need for a battery.
Normal watering will resume when AC
power is restored.
No Battery Required…
Maintain time of day up to four weeks
The circuitry of the Pro-C has such low
power consumption that the controller will
accurately track the time of day for up
to four weeks after AC power has been
removed from the controller by the
user or in the event of a power outage.
This timekeeping occurs without need
for a battery. When power is restored
the controller will continue to water,
right on schedule. The controller will also
recharge its circuits to allow another 4
weeks of time keeping.
Self-Diagnostic Electronic Short Circuit
Protection…
No fuses to worry about; only faulty sta-
tions stop watering
The Pro-C automatically skips shorted
stations allowing the rest of the system
to operate as normal. The self-diagnostic
electronic short circuit protection system
is very benecial to the user because of
its ability to aid in identifying eld 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 operating 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 con-
troller will skip over that station and con-
tinue to water the rest of the zones in the
program. The controller will indicate what
zone is shorting by showing the station
number followed by ERR in the LCD dis-
play. 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.
