A note about multiple programs
Your sprinkler timer provides the flexibility of using 2
independent programs (A, B) . The programs are where
you store all of your sprinkler settings . each program
consists of a group of stations set to specific start
times and run times . Multiple programs allow you to
run different valves on different days with different
run times . While many applications only require one
program (A), using multiple programs (A, B) can be
useful for drip areas, newly planted lawn, or rotary
sprinkler stations . Using programs to group stations
with similar water needs will maximize irrigation
efficiency .
Primary programming can be accomplished in just a
few basic steps .
