Introduction: What is a Watering Cycle?
Each watering cycle opens and closes all the valves assigned to a
program, in sequence, starting with the lowest valve number. For
example, in the sample watering plan shown, program A has two
start times which initiate two watering cycles. All four valves in the
program water in sequence, two times each day, once at 7:OOam
and once at 5:OOpm. The LD4 is designed to operate up to four
valves. The LD6 is designed to operate up to six valves. Each
can be set to start two watering cycles per program. Each of the
two programs are completely independent of each other giving
you the freedom to include any combination of valves in each
program and the ability to select different watering days and start
times for each program. After programming, write your watering
plan in pencil on the back of the programming reference card,
located in the controller pull-out pocket. For the days you have
selected in programs A and B. each programmed start time turns
on each selected valve in sequence, from the lowest valve
number to the highest valve number.
