HrC-300 Series
sprinkler controller. our designers have combined the
simplicity of touch-screen programming with the flexibility
and accuracy of digital electronics to give you a controller
that is easy to program and extremely versatile. This con-
venient controller lets you run automatic or manual water-
ing programs with a wide spectrum of features, including
remote control and rf sensor operations.
Please read this manual completely before you begin
programming and using the controller.
important Features and capabilities
Three independent Programs
HrC 300 sprinkler controller’s offer three independent pro-
gramming functions – Programs a, B, and C offer watering
flexibility across variable landscapes ie. Trees, Turf, Xeri-
scape, etc… any of the watering stations can be assigned
to individual or all programs. for example, stations that
water your garden and flower beds could be assigned to
Program a and watered daily starting at 8 a.m., while sta-
tions that water your lawn could be assigned to Program B
and watered every third day starting at 5 a.m. Program C
could be selected for drip or other low-flow stations.
Simultaneous c Program
The C program is specially designed for drip or other
low-flow stations that need to run for longer durations
or at more frequent intervals. The HrC 300 is able to run
concurrently the C program with a or B programs. See
“Stacking” feature on the next page.
“Stacking” Feature
occasionally you will inadvertently program one program
to water prior to another program finishing its watering
cycle. This could result in insufficient water flow neces-
sary to operate the system. The HrC 300’s unique logic will
override human programming error and begin the next
water cycle after completion of the first cycle for the a and
B program. The C program will run concurrently with the
a and B programs. In order to ensure sufficient available
flow for the a and B programs, the C program should be
reserved for low-flow zones such as drip zones.
Docking Port
Mounting your HrC 300 to the wall is easy and convenient.
The HrC 300’s “docking port” is affixed to the wall and all
wires are connected to it. The controllers programming
unit is then conveniently slid in to the docking station. This
feature allows you to walk around the yard while program-
ming each station to meet the needs of the landscape.
remote control capabilities
The HrC 300 has an rf reciever built into its circuit board.
When used in coordination with the HrC 300-12-Tr (rf
Transmitter) the HrC 300 programming can be overrid-
den. This feature allows you to turn stations on and off on
the spot from anywhere within range. The 433 megahertz
remote frequency is approved for use in the united States,
Canada, Europe and australia, and permits an effective
line-of-sight range of 300 feet (reduced to 200 feet with
obstructions).
Programming information Stored Safely
in Non-Volatile Memory
all programming information for Programs a,B, and C are
stored indefinitely in the HrC 300’s non-volatile memory.
non-volatile memory means your programming won’t be
lost or erased when or if both primary and battery power
are suspended.
convenient, easy-to-read
Touch-Screen LcD Display
The HrC 300’s back-lighted, touch-screen lCd display
is convenient to program and easy to read under any light-
ing conditions. You may use either your finger or the built-
in stylus to manipulate programming on the touch screen.
choice of Five Languages
You can easily set the lCd display to read in any of five
languages: English, Spanish, french, German or Italian.
Water Budgeting
This convenient feature provides a quick, easy way to
increase or decrease the watering durations of all stations
in both programs to match seasonal watering needs. You
won’t have to adjust each station’s watering time individu-
ally.
rain Sensor (Optional)
an optional rain sensor can be purchased separately to
prevent programmed watering for a period of time after
rain falls (determined by the amount of rain and how
quickly the sensors dry out). The HrC-300 series controller
is rf sensor ready. The HrC-300-rS-rf wireless rain/
freeze sensor transmitter is ready for immediate installa-
tion and syncronization with the controller. no additional
wireless receiver is necessary.
