Irrigation System Basics
The three major components of every automatic sprinkler
system are the controller, the control valves and the
sprinklers/emitters.
The controller is the brain of the system, signaling each
control valve when and how long to open. The valves are
connected to numbered terminals within the controller,
and identified as Station 1, Station 2, etc. Each station
controls a group of sprinklers in a specific portion of the
landscape called a watering "Zone." The zones are gen-
erally laid out according to the type of plant material
being watered and the type and flow rate of the sprin-
klers used to distribute the water.
Automatic controller "Programs" are used to establish
and organize different watering schedules. The TMC-212
provides three independent watering programs, designated
A, B and C. and are established by specifying: what day(s)
of the week to water – called watering days, what time to
start watering – called start time and how long each sta-
tion runs – called station time.
Each station can be assigned to each program and have a
different amount of run time in each program.
When an automatic program starts, each station with an
assigned run time in the program will operate one by one in
numeric sequence from lowest to highest station number
