This is the maximum water holding capacity of the soil, in other words, the level of soil<br />

moisture left in the soil after drainage of the gravitational water. Irrigation to levels above<br />

field capacity will result in runoff or drainage as gravitational water.<br />

A device that is capable of measuring water flow and water used<br />

The abbreviation for gallons per hour<br />

The abbreviation for gallons per minute<br />

A grouping of plants that have similar water requirements and can be watered the same<br />

The process by which water passes through soil – the liquid permeates the soil by passing<br />

through the pores in the soil<br />

(also known as K-factor) A calibration factor for a flow device expressed in pulses per unit<br />

volume. The K value is used to calibrate the volumetric throughput of a flow device.<br />

Manufacturers give the K value (or K-factor) of their flow device in the device<br />

specification.<br />

Within a zone group, there is one primary zone and all other zones are then “linked” to<br />

the primary and will get their programming information from the primary (water time,<br />

program, schedule, etc.)<br />

This water strategy is programmed by setting the schedule to water every day and then<br />

setting the biSensor to allow watering when the moisture level drops below this limit –<br />

the controller can automatically set this lower limit after a calibration cycle, or it can be<br />

set manually.<br />

An automatic or manual valve installed at the supply point which controls water flow into<br />

the system mainline piping. The controller allows four master valves (MV1 to MV4). By<br />

default, all master valves are assumed to be Normally Closed, unless they are specifically<br />

programmed to be Normally Open.<br />

When the soil moisture content reaches this level, irrigation needs to start. In most cases,<br />

the maximum allowed depletion level is just before the plants begin to show visible signs<br />

of stress.<br />

The climate of a specific location within a landscape. Variations in climate are influenced<br />

by subtle differences in temperature, humidity, and wind exposure. Microclimates can<br />

have a significant impact on plant water needs.<br />

Normally closed master valve – built in to the BL-5402NCMV flow device<br />

Normally open master valve – built in to the BL-5402NOMV flow device. It can monitor<br />

high flow and shut down independently from the controller.<br />

A calibration factor for a flow device that compensates for limitations in the device’s<br />

ability to measure small signals adequately. Manufacturers give the maximum amount of<br />

offset associated with their flow device in the device specification<br />

When soil moisture content reaches this level, plants can no longer get water from the<br />

soil, and they will wilt and die<br />

A decoder device that interprets the signals that it receives from the controller and tells<br />

the valve to turn on or off. A powered decoder is designed to retrofit into existing systems<br />

and requires 120 VAC service at installation location.<br />
