Column Description

AIM

Advanced ET

Editable

Adjusted Runtime

The adjusted runtime that is manipulated via ET calculations and manual percentage adjustments.

Yes

Yes

No

Controller Address

The address of the associated controller.

Yes

Yes

No

Current Depletion

The amount of depletion currently associated with the station. Range 0-100 percent depletion.

No

Yes

Yes

Design GPM

The typical GPM used by the station. Typically synonymous with nominal flow provided via Learn Flow.

To get accurate flow management, ensure that Learn Flow process yields stable and accurate nominal flow values.

Yes

No

Yes

ET Calculation Mode

Denotes the mode in which the station’s ET is calculated:

•No ET: No ET calculation. Runtimes, max cycle times, and min soak times are entered manually.

•Basic ET: Station adjusted runtimes are calculated via Basic ET. Base runtimes, max cycle times and min soak times are entered manually.

•Advanced ET: Station base runtimes, adjusted runtimes, max cycle times, and min soak times are all calculated via Laguna’s Advanced ET algorithm.

No

Yes

Yes

Infiltration Rate

Infiltration Rate is used in determining the minimum soak time needed between watering cycles to ensure that no runoff occurs.

It measures the rate of inches of moisture, per hour, which water percolates into the specific soil after infiltration has decreased to a low and nearly constant value.

No

Yes

No

Master Valve Columns (1-3)

The associated master valve(s) the station uses when it is activated. Note that DX2 can only have one master valve association per station while the DX3 controller can have multiple.

No

No

Yes

Maximum Allowed Depletion

Max Allowable Depletion is the maximum percentage of plant available water which will be allowed to be removed from the root zone before the next watering is scheduled. This value is a factor for determining irrigation frequency.

No

Yes

Yes

Maximum Cycle Time

The maximum amount of time a station can be on for a given start time.

Yes

Yes

Depends

Minimum Soak Time

The minimum amount of time that a station must be off between cycle times.

Yes

Yes

Depends

Node

The name of the node associated to the station if applicable.

Yes

No

No

Percent Adjust

A percentage adjust applied to the end of all other adjustments from ET.

Yes

Yes

Yes

Plant Type

The plant associated with the station.

No

Yes

Yes

Precipitation Rate

The precipitation rate is the average amount of water in inches applied to an irrigation zone in one hour. The precipitation rate is the result of sprinkler type, spacing, arc pattern, and operating pressure.

No

Yes

Yes

Priority

A value used in AIM to decide when a station turns on. Note that priority is not guaranteed order. See AIM literature for more information.

Yes

No

Yes

Programming Mode

Denotes the mode in which the station is scheduled in:

•Advanced ET Mode: The station’s schedule will be computed in Advanced ET only mode that only considers the controller’s constraints.

•Advanced ET and AIM Mode: The schedule will be generated by AIM.

•AIM: The schedule will be generated by AIM.
Conventional: The station will adhere to the conventional programming. Advanced ET will continue to calculate, but no ISC schedules will be generated.

Yes

Yes

Yes

Root Zone Depth

Root Zone Depth is used to determine the size of the moisture reservoir.
This in turn is used to determine water-holding capacity.
Station runtime and frequency of irrigation are affected by root zone depth.

No

Yes

Yes

Site Microclimate

Site Microclimate defines particular stations environmental characteristics to adjust for extraordinary conditions such as dry, hot, windy, shady, cool, etc.
The top of the scale represents the high microclimate conditions that tend to increase the evaporative conditions of the hydrozone.

No

Yes

Yes

Slope

The degree of slope that the station is watering.

No

Yes

Yes

Soil Type

The soil associated with the station.

No

Yes

Yes

Station Efficiency

The efficiency in percentage of the station.

No

Yes

Yes

Station Name

The user-defined name of the station.

Yes

Yes

Yes

Station Number

The station’s number.

Yes

Yes

No

Suspend Mode

Prevents stations from participating in scheduling indefinitely until removed.

ET Calculations continue while suspended.

Yes

Yes

Yes

Tag

A user-defined string or note that is helpful for ISC management.

Yes

Yes

Yes

Total Runtime

The base runtime that is entered manually or generated without adjustments.

Yes

Yes

Depends

Use Pumps (1 and 2)

The associated pump(s) the station uses when it is activated. Note that DX2 controllers can only have one pump association per station.

No

No

Yes

Water Days

The water days in which the station may run if using Advanced ET or will run otherwise.

Yes

Yes

Yes

Water Holding Capacity

Available Water Holding Capacity is used in determining the runtime as well as the maximum watering runtime before runoff occurs.
It measures the number of inches of moisture, per inch of soil depth, which can be held by the specific soil

No

Yes

No
