mode of operation.
• Manual Rain Switch (Automatic Watering – No Waterin
g
) provides a means of quickly
turnin
g
off all irri
g
ation pro
g
rams without disturbin
g
the stored pro
g
ram(s). When the
switch is placed in the No Watering position the display shall show “RAIN OFF”
• Connectivity for any one of the followin
g
: rain, moisture, or freeze sensor device. The
enablin
g
of this device can be performed on a per pro
g
ram basis. When the sensor is
“
active” irri
g
ation shall stop and the display will indicate that the sensor is active. This
feature allows non-irrigation programs to execute independent of this device.
•
T
he ability to select either ODD or EVEN day waterin
g
on a per pro
g
ram basis. (When
either of these features is selected, the controller shall not water on the 31st day of
the month.)
• Selectable cycle and soak irri
g
ation pro
g
rammin
g
or conventional pro
g
rammin
g
on a
per-program basis.
• Programmable cycle runtime, Max Cycle Time, and Soak Time on a per station basis.
• Automatic minimization of the water window by intelligently scheduling station starts
when other stations are satisfying their SOAK TIMES.
• Controller supports Quick Station pro
g
rammin
g
in the Cycle and Soak pro
g
rammin
g
mode.
•
T
he controller provides a display of the total runtime of the pro
g
ram usin
g
the
REVIEW feature of the controller. The cycle and soak feature intelli
g
ently displays the
total runtime of the pro
g
ram, the controller considers all soak delays, optimized
program features, water budget percentage and inter-station delays.
• Optimized water savings. Re-calculated station run times are executed to the nearest
second.
1.3 Convenience Features
The controller shall have:
• Easy to understand and use keyboard layout, provides ease of use durin
g
programming and review.
• Multiple displays provide a simple way of programming and information review.
• Durin
g
pro
g
ram execution the controller shall display the executin
g
pro
g
ram number,
the flow in GPM, and the station runtime countdown in hours, minutes and seconds.
• Programmable Controller Security Access code to prevent unauthorized use or
modifications to be made of the controller’s pro
g
rams. This feature is enabled by
entering a security access code from 1 to 4 digits in length.
• Review key to display all pro
g
ram parameters on a per pro
g
ram basis. Successive
invocation of the key shall display pro
g
ram parameters one by one. Depression and
subsequent hold of this key shall allow rapid review of program parameters.
1.4 Diagnostic and Fault Detection
The controller shall have:
• Programmable audible alarm. When enabled this alarm will “chirp” once every six
seconds whenever any flow fault condition occurs. The alarm will continue until reset
by the user.
• Automatic field wire fault detection enables the TWICE Two Wire Interface module to
sense a short or an open in the field wire and instantly turn off that station. The
TWICE display will report the fault condition any time a field wire fault occurs.
