BaseStation 3200 Advanced Irrigation Controller Manual
microclimate The climate of a specific location within a landscape. Variations in climate
are influenced by subtle differences in temperature, humidity, and wind
exposure. Microclimates can have a significant impact on plant water
needs.
NCMV Normally closed master valve
NOMV Normally open master valve – It can monitor high flow and shut down
independently from the controller.
offset value A calibration factor for a flow device that compensates for limitations in
the device’s ability to measure small signals adequately. Manufacturers
give the maximum amount of offset associated with their flow device in
the device specification.
permanent wilting
point
When soil moisture content reaches this level, plants can no longer get
water from the soil, and they will wilt and die
point of
connection
Also known as “water source”
The place where the irrigation system is connected to a water supply
powered decoder A decoder device that interprets the signals that it receives from the
controller and tells the valve to turn on or off. A powered decoder is
designed to retrofit into existing systems and requires 120 VAC service at
installation location.
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.
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.
