mode of operation.
• Manual Rain Switch (Automatic Watering – No Waterin
) provides a means of quickly
turnin
off all irri
ation pro
rams without disturbin
the stored pro
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
: rain, moisture, or freeze sensor device. The
enablin
of this device can be performed on a per pro
ram basis. When the sensor is
active” irri
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.
•
he ability to select either ODD or EVEN day waterin
on a per pro
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
ation pro
rammin
or conventional pro
rammin
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
rammin
in the Cycle and Soak pro
rammin
mode.
•
he controller provides a display of the total runtime of the pro
ram usin
the
REVIEW feature of the controller. The cycle and soak feature intelli
ently displays the
total runtime of the pro
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
programming and review.
• Multiple displays provide a simple way of programming and information review.
• Durin
pro
ram execution the controller shall display the executin
pro
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
rams. This feature is enabled by
entering a security access code from 1 to 4 digits in length.
• Review key to display all pro
ram parameters on a per pro
ram basis. Successive
invocation of the key shall display pro
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.
