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: The primary zone and the other linked zones within a hydrozone. This group of zones can be watered on the
same interval.
serial port: A type of external connection on a computer. The external connector for a serial port can be either 9 pins or 25 pins.
Devices are connected with a serial cable.
soak time: In an Intelligent Soak Cycle, soak time is interspersed with watering time in order to prevent runoff.
software: Computer programs and related data that instruct a computer what to do and how to do it.
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.
soil moisture sensor: See biSensor™ Soil Moisture Sensor
smart controller: Irrigation controller that uses ET information to water when needed and to make seasonal adjustments of run
times
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: A mode in the controller software that configures a zone to be watered on a timed schedule rather than on 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-way communication: In a Baseline irrigation system, the controller sends a command over the two-wire to a biCoder. The
biCoder then lets the controller know that the command was received and understood. If the biCoder does not respond, the
controller knows that there is a problem, and it will alert you. Most competing two-wire systems do not implement two-way
communication.
two-wire irrigation wiring: Wiring that replaces the typical bundle of conventional irrigation wires with just two wires. In a two-
wire irrigation system, only one valve needs to be connected directly to the controller, as opposed to every valve in a
conventional system. In addition to transmitting power, a two-wire system can also transmit data.
upper threshold: If you are using soil moisture sensors to control watering, the upper threshold is the point at which the soil
water content is high enough to halt watering.
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.
water budget: In the BaseStation 6000 system, the water budget functionality enables you to define and track the total flow for
each Flow biCoder per month. You can configure the target flow value in GPM for the Flow biCoder and how the system will
react when this number is reached.
water window: The time available for watering through an irrigation system. Typically, all days and times would be available for
watering unless there are watering restrictions or you need to set aside a time for mowing.
weather station: Meteorological sensors that monitor weather conditions and send data to a computer.
Wi-Fi: A method for wirelessly connecting electronic devices
zone: A designated area of landscaping that is watered by a specific valve
