BaseStation 3200 Advanced Irrigation Controller Manual
primary zone The zone within a scheduling group that all other linked zones are linked to. Changing the
programming on this zone will adjust the programming on all linked zones, resulting in
saved time and consistency. If you are using a biSensor, the primary zone is the zone that
the sensor is connected to.
program A program is a controller programming concept used to organize watering events. Each
program can have different schedules, water days, watering strategies, master valves, etc.
The BaseStation 3200 supports up to 20 programs.
pump start A relay or relay-type device that initiates turn on of a pump, typically a high horsepower
electrical or motor driven pump.
runoff When the soil moisture content is at the saturation level, any excess water from rain,
snow melt, or irrigation drains to a low point in the landscape
saturation When the soil moisture content is at this level, nearly all of the spaces between soil
particles are filled with water. After a soil has reached saturation, it does not become
more saturated; although, in some situations where water is trapped, it can become
flooded.
scheduling group A group of one or more zones that have been linked together for irrigation scheduling. A
scheduling group must have one primary zone, and may have one or more linked zones.
Irrigation for all zones in a scheduling group will follow the watering strategy of the
primary zone, but actual irrigation run times and soak/cycle behavior will scale as
programmed relative to the primary zone.
soak cycle When a zone waters using a soak cycle, the total watering run time includes periods of
watering (run times) interspersed with periods of non-watering times (soak times).
soil-moisture
content
The ratio of the volume of contained water in a soil compared with the entire soil volume
soil-moisture
deficit
When soil dries (for example, by evaporation), the measurable shortage of water in the
soil is known as the soil-moisture deficit. It also refers to the amount of water needed to
return to field-capacity moisture content.
time domain
transmission (TDT)
A measurement of how much the electrical signals in the soil are slowed down by the
presence of water
timed zone Any zone programmed to water on a time/day schedule, not a smart irrigation schedule
transpiration The loss of water vapor from parts of plants. Water is lost primarily from the pores on the
leaves but also from stems, flowers, and roots
two-wire This site wiring technique consists of a cable with an outer insulation, around two internal
insulated wires, being used to provide communication and power for all valves and other
devices throughout the site. It provides full two-way communication much like a
computer network.
upper limit This water strategy is programmed by setting the schedule to water with Historical ET
Calendar day intervals, or alternatively with specific days of the week, and then setting
the biSensor to adjust the water run time to “fill up” the moisture to the upper limit (field
capacity). The controller will water a program at each start time and will modify the run
time based on the moisture depletion level.
valve A device that opens to allow water to flow to the sprinkler heads or emitters in a zone. It
closes to halt watering for that zone.
