Glossary
Flow Max
Multiple controller system configuration comprised of one submaster and one or
more satellites. This unique feature allows controllers to utilize a single point of
connection to share devices (i.e. Flow Sensors, Master Valves, Pumps, etc.) and
intelligently manage system operation.
Flow Sensor
A rotating paddle device placed in a main water line used to measure water flow. The
device must be calibrated using K and Offset values to compensate for pipe size.
Inter Station Delay Time
The amount of time between when one station stops irrigating and the next
scheduled station begins.
Irrigation Program
See Program.
ISC
Individual Station Control (ISC) is an alternative programming mode that treats an
individual station like a program. The user enters water days, start times, and runtimes
for each station programmed as an ISC.
K Value
A numeric value required for the proper setup/ calibration of flow sensors.
Learn
Feature that automatically establishes upper and lower limits for flow and current.
Limit Checking
The controller validates user defined upper and lower limits for flow, and current
readings. Violations are reported in the warning/report buffer.
Main Flow
The maximum flow limit for a complete irrigation system.
Manual Control
Manual control provides maintenance personnel the ability to turn on/off individual
stations and programs. The controller can also be placed in rain shutdown for either a
programmable or indefinite amount of time.
Master Valve
A dedicated controller output which is activated by the controller each time a program
start time occurs (typical operation). This output is typically connected to a Pump or
another valve which acts as the master enable for all irrigation.
