Introduction
Welcome To Rain Bird
Thank you for purchasing your new state-of-the-art Rain Bird
ET Manager Cartridge for the ESP-LX Modular Controller.
For more than six decades, Rain Bird has led the irrigation industry in meeting all of your water management needs by providing the highest quality products and services available.
ET Manager Cartridge
The ET Manager Cartridge brings evaporation & rain based control to the ESP-LX Modular Controller. The ET
Manager Cartridge uses real time weather information to automatically adjust watering run times to meet the needs of the landscape. The ET Manager Cartridge may be used on both indoor and outdoor applications. Key features which the ET Manager Cartridge introduces to the ESP-LX Modular
Controller include:
• Seasonal Adjust percentage automatically adjusted according to current weather information to replace water lost through evaporation.
• Weather interrupts based on Temperature, Wind, and
Rain to cancel watering in case of inclement weather.
• Displays real-time weather information
• Logs including Interrupt history, Weather Information and Irrigation events showing amount of water applied and number of days watered.
The ET Manager Cartridge is programmed to receive hourly weather information from a local Weather Reach Signal
Provider (WRSP) and uses this information along with sitespecific settings to determine when and how much water your landscape needs.
The ET Manager Cartridge manages watering by making adjustments to the Seasonal Adjust percentage. When weather parameters are such that watering is not needed, the Seasonal Adjust percentage will be set to 0percentage.
When watering is needed, the Seasonal Adjust percentage will vary depending on watering needs and user-defined settings which limit the lowest and highest Seasonal Adjust percentage you want to allow.
Weather parameters used to measure evaporation (ET) include:
•
•
Solar Radiation
Temperature
•
•
Wind
Humidity
1
ET Manager Cartridge for ESP-LX Modular
Rainfall is also measured and may be received either from the weather signal or an on-site rain gauge (the ET Manager
Cartridge accepts input from both 1mm/tip and 0.01”/tip rain gauges).
The Tipping Bucket Rain Gauge (ETM-RG) is the recommended on-site rain gauge for use with the ET Manager Cartridge.
To find your local Weather Reach Signal Provider, please check the listing in the ET Manager Scheduler software found on the ET Manager Cartridge Resource CD (included) or visit www.rainbird.com/wrsp.

Basic Programming
The ET Manager Scheduler software found on the ET
Manager Cartridge Resource CD will walk you through all settings for both the ESP-LX Modular Controller and the ET
Manager Cartridge.
Programming The ESP-LX Modular Controller
Begin by completing programming for ESP-LX Modular
Controller: Please refer to your ESP-LX Modular Controller
Installation, Programming, & Operation Guide.
It is recommended that your ESP-LX Modular Controller be programmed with start and run times that your landscape would need during the hottest, driest part of the year. You will need to determine the approximate amount of water applied in inches (or millimeters) for a single start time.
The ET Manager Cartridge will set the Seasonal Adjust percentage to adjust the peak of the season watering schedule to meet watering needs based on current weather information.
!
NOTE:
It is important to keep all run times for a valve on one Program. For example do not turn Valve 1 on with both Programs A and B.
ET Manager Resource CD
The ET Manager Cartridge features an EZ Setup Wizard to simplify the programming process (turn the dial to ET
Manager / IQ Communications).
The EZ Setup Wizard consists of the essential settings which are necessary to receive the weather signal and to manage irrigation. Resources available to determine these settings can be found on:
• The ET Manager Scheduler software on the CD included with your ET Manager Cartridge.
• A Weather Reach Signal Provider Information Sheet which can be obtained from your Rain Bird Distributor, your installation contractor, or via PDF download at www.rainbird.com/wrsp.

Run Time Limits
Run Time Limits controls the highest and lowest Seasonal
Adjust percentage you want the ET Manager Cartridge to be able to set. Default Settings are Minimum Run Time: 80%,
Maximum Run Time: 120%.
Minimum Run Time
The Minimum Run Time gives you the ability to decide the smallest percentage of your watering cycle you will allow to be applied to your landscape. Setting this percentage to a low number will mean that your ET Manager Cartridge will allow watering even if only a small amount of evaporation has occurred. Setting this percentage to a high number will delay watering until more evaporation has occurred, providing oxygen to the roots which will encourage them to grow deeper, without sacrificing the health of the plant.
Maximum Run Time
The Maximum Run Time gives you the ability to decide the largest percentage of your watering cycle you will allow to be applied to your landscape. There may be instances where your landscape has dried out more than a regular watering cycle will be able to replace. In this situation the ET Manager
Cartridge will adjust the Seasonal Adjust percentage above
100% causing your sprinklers to run longer than their normally scheduled time. The Maximum Run Time may be helpful if there is a certain amount of time you want your watering to stay within.
If water days are limited, the ET Manager Cartridge looks ahead each day to determine if watering should occur, based on the last 24 hours of evaporation, even though the current Moisture Level has not yet met or dropped below minimum levels. In this situation, the ET Manager Cartridge will ignore the Minimum Run Time limit to fill the moisture level in preparation for the upcoming day(s) that are turned off.
!
NOTE:
The ET Manager Cartridge works to keep your
Moisture Levels filled and will not set a Seasonal Adjust percentage that would cause the Moisture Level to go above the filled amount.
For Example: If the Minimum Run Time limit is set to 80% and
Maximum Run Time limit is set to 120% with run times set to
10 minutes, the shortest run time that could occur would be
8 minutes, while the longest would be 12 minutes.

Landscape Adjustment Percentage
The Landscape Adjustment Percentage is used to adjust for site-specific landscape needs for each Program and is applied to the calculated ET. As a general rule the Landscape
Adjustment Percentages should range between 60% - 100% for turf grass and 40% - 80% for shrubs. The default setting is
100% for all programs.

Effective Rain Settings
Effective rain is the amount of rain that is an available source of water for the plant. When rainfall amounts and intensities are extreme, not all rainfall will stay within the root zone. To restrict the amount of rain recognized by the system, two effective rainfall limits should be programmed: Max Hourly
Rain and Saturation Allowance (for each program).
• The Maximum Hourly Rain is the maximum amount of rain that will be used in an hour to adjust the soil moisture level.
• The Saturation Allowance is the amount of rain it takes to saturate the soil after satisfying the total irrigation amount before run-off occurs. Unique Saturation
Allowance settings can be made for each program and are typically programmed as half the total irrigation amount. Default settings are; Max Hourly Rain: 0.25;
Saturation Allowance: 0.10 for all Programs.

Rain Region
Rainfall data is received by the ET Manager Cartridge in the hourly weather signal or from an optional on-site rain gauge. Another option for rain data is a Rain Region. Like the weather region number, a rain region number represents a rain gauge accessed by the Weather Reach Signal Provider who then broadcasts the rain region data. The user programs the rain region number to correspond to a rain region that closely represents rainfall for the location of the ET Manager
Cartridge. To determine if a Rain Region is available in your area, refer to the Signal Provider Information Sheet for your signal provider.

Troubleshooting
Alert Conditions and How To Respond
There are certain situations which could cause an Alert Condition. The following is a list of all possible Alert Conditions which could be displayed, what they mean and what action (if any) may need to be taken.
Symptom
No Signal Service
Activation Required
Please Contact Signal
Provider
Probable Cause
Your Weather Reach Signal Provider (WRSP) can send a “No Signal Service” signal to cancel weather signal reception. Typically this would happen only if the terms of the service agreement were not met. Subscription based weather signal service requires device activation by the Weather Reach Signal Provider.
Temperature Interrupt If the hourly weather signal contains air temperatures that reach or are below the Temperature Interrupt setting, watering is canceled. Once the air temperature rises above the programmed interrupt setting, as received in the hourly weather signal, the
Temperature Cancel will clear.
Wind Interrupt
If the hourly weather signal contains wind speeds that reach or exceed the Wind Interrupt setting, watering is canceled. Once the wind speed decreases below the programmed interrupt setting, as received in the hourly weather signal, the Wind Cancel will clear.
24 Hour Rain Interrupt If rainfall over the last 24 hours is at or above the Rain Cancel setting, watering is canceled. Once the total rainfall in the last 24 hours drops below the Rain Cancel setting, the 24 Hour Rain Cancel will clear.
1 Hour Rain Interrupt
If rainfall over the last hour is at or above the 1 Hour Rain setting, watering is canceled. Once the total rainfall in the last hour drops below the 1 Hour Rain setting, the 1 Hour Rain Cancel will clear.
Provider Interrupt
The Weather Reach Signal Provider (WRSP) can send a signal to interrupt watering. This may be necessary during an emergency condition in the community requiring watering to be suspended to limit the demand on the community water system. As a service, your WRSP may also watch weather forecasts and choose to interrupt watering for expected conditions such as large rain storms.
A Provider Interrupt lasts for 24 hours. For information regarding a current Provider Interrupt, contact your Weather Reach Signal
Provider.
Action
Contact your Weather
Reach Signal Provider to establish services.

ET Manager Cartridge for ESP-LX Modular
Symptom
No Weather Signals have been received in the last 24 Hours
No Paging Signal
Detected
Probable Cause
If the ET Manager Cartridge does not receive weather data for
24 hours, this message will be displayed. There are 5 reasons the weather signal would not be received for 24 hours:
1. The Signal Provider Code has not been set correctly.
2. The weather region number has not been set correctly.
3. Weak radio reception has caused the ET Manager Cartridge to miss 24 hours of messages.
4. Signal service has been canceled by the Weather Reach
Signal Provider.
5. The Signal Provider is having technical difficulties.
The ET Manager Cartridge verifies the presence of the Paging
Signal every minute. If the paging signal is not detected after a period of time, this message will be displayed. There are 3 reasons the weather signal would not be detected;
1. The radio needs to be reset.
2. The Signal Provider Code has not been set correctly.
3. Weak radio reception.
Action
Verify that the Signal Provider Code and weather region have been programmed correctly. Turn the dial to the ET MANAGER/IQ SETTINGS position, from the Moisture
Levels screen, press the Alrt button to check for other Alert Messages. Either the “No
Signal Service Activation Required Please Contact Signal Provider” or “Low Weather
Signal Accuracy” message will be displayed, refer to trouble shooting for applicable alert message. Contact the Signal Provider if you believe they are having technical difficulties.
NOTE: All missed messages are replaced with a calculated ET value based on previously received weather information and the historical ET programmed in your ET Manager.
If this Alert Condition occurs, wait two minutes to ensure the weather signal will not be detected within the next few minutes. If the Alert Condition remains, follow these steps:
1. Follow the steps on page 15 to Test the Weather Signal.
2. Press More, then Reset, then Back.
3. Wait two minutes, if the Signal changes from “Not Detected” to “Detected,” your paging signal has been restored.
4. Verify the Signal Provider Code is programmed correctly.
If the Signal Provider Code is programmed correctly and the Alert Condition remains, an external mounting kit may be needed to improve radio reception. Contact Rain Bird to find out more information about an optional Remote Mounting Kit (ETM-RMK)

56
Symptom
Low Weather Signal
Accuracy
Local Rain Gauge Input
Failure Check Wiring
Historical ET is NOT set
Signal Provider Code is
NOT set
Probable Cause
If data reception accuracy is less than 50% then the Low Weather
Signal Accuracy message is displayed. There are 2 reasons the
Weather Signal Accuracy may be low:
1. Weak radio reception.
2. Signal service has been canceled by the Weather Reach
Signal Provider.
If you are using a rain gauge to collect rain data and this message is displayed, there is a problem with the input to the Rain Tip wire terminal.
The ET Manager Cartridge uses historical ET values set by the user as a backup in the event weather signal service is not available.
If no Historical ET has been programmed, this message is displayed.
If this message appears, your ET Manager Cartridge has been installed but not programmed with a Signal Provider Code.
PGM X is at Wilting Point
The ET Manager Cartridge computes the current Moisture Levels for each Program. If conditions cause the Moisture Level for a program to dry out to the negative Total Irrigation amount, this is considered Wilting Point and the Alert message is displayed.
Action
Weak radio reception or radio interference may cause missed weather signals. An external mounting kit may be needed to improve radio reception. Contact Rain Bird to find out more information about an optional external mounting kit.
It may be that your WRSP had system problems that interrupted the weather signal for a period of time. If data continues to be missed for several days, contact your
WRSP, to check if there has been interruption in the weather signal.
NOTE: All missed messages are replaced with a calculated ET value based on previously received weather information and the historical ET programmed in your
ET Manager.
Verify the on-site rain gauge is installed and wired properly. Check the length of the rain gauge wire for cuts or nicks, replace damaged wire. Check the rain gauge for damage.
Monthly historical ET values for your area are available from the Historical ET database included in the ET Manager Cartridge Resource CD. Look up your city and state, then program the monthly values into the ET Manager Cartridge, see page 17.
Navigate the menus to the Signal Provider Code and program the appropriate Signal
Provider Code see page 17. To obtain your Signal Provider Code, contact your Rain
Bird Distributor, your installation contractor, or go to www.rainbird.com/wrsp.
Review the days available for watering and add additional days if possible. Or change the Irrigation amount to a higher value.

Landscape Conditions and How to Respond
Symptom
Dry or Wet Spots in
Landscape
Probable Cause
Dry and wet spots are often caused by inefficiency in the distribution of water by your sprinkler system.
Action
1. Check the sprinkler heads near the spot that is dry or wet. It is possible that a broken or clogged head or nozzle needs to be replaced.
2. Check the layout of your sprinkler design. Proper sprinkler designs should ensure head to head coverage. Changing a nozzle size, adding or moving a head may improve water distribution.
3. If steps 1 and 2 do not solve the problem, check the run times in the
LXM adding additional time for the station where the spot appears may compensate for minor sprinkler system inefficiencies.
NOTE: Manual watering to the spot will speed recovery. Adjust the run time using small intervals of time, 1 or 2 minutes. Monitor the spot after an adjustment has been made. This will help determine what run time is optimal to prevent dry or wet spots.
ET Manager Cartridge for ESP-LX Modular
58
Symptom
Entire station or zone is too dry or wet
Probable Cause
Stations or zones are the distinct areas in your landscape watered by one valve. Dry or wet stations or zones are often caused by a run time problem programmed in the LXM.
Action
1. Start the zone to confirm that the zone is operating properly.
2. Check the run time on your LXM for the station. The dry or wet station can be caused by too little or too much watering.
3. Manually water the station if it is too dry to get it the water it needs.
4. Adjust the run time using small intervals of time, 1 or 2 minutes. This will help determine what run time is optimal to prevent dry or wet stations.
Several stations in a
Program are too dry or too wet
There are two possible causes for all the stations in a Program being to dry or too wet:
1. A run time problem programmed in your sprinkler controller.
2. The Irrigation Amounts were not correctly programmed
1. If the Program is too dry, manually water the Program to get it the water it needs.
2. Check the run times on your LXM. The dry or wet Program can be caused by too little or too much run time for each station.
3. Adjust the run time(s) using small intervals of time. This will help determine what run time is optimal to prevent dry or wet stations.
4. If steps 1 and 2 do not fix this problem, adjust the Irrigation Amount for the
Program. See Appendix , Determining the Irrigation Amount, for more information on this setting.
NOTE: You want to increase your Irrigation Amount if you are experiencing a wet Program and you want to decrease your Irrigation Amount if you have a dry Program.
59
ET Manager Cartridge for ESP-LX Modular
Symptom
The site is watering every day
I want to water on the next cycle
After a rainstorm my sprinkler system resumes watering too soon
Probable Cause
There are three possible causes of why the site is watering everyday:
1. The Irrigation Amount(s) are programmed too low.
2. The Minimum Run Time Limit is programmed too low.
3. ET rates are high enough that daily watering is necessary
(no action is required)
There may be occasions when, in your judgment, the sprinklers should water the next watering cycle.
There are several reasons the sprinkler system resumes watering too soon after a rainstorm:
1. The rainfall received in the weather signal may not correctly represent rainfall at your site.
2. Location of your optional on-site rain gauge may be poorly sited.
3. The rain source in the ET Manager Cartridge may be programmed incorrectly.
4. Effective Rain settings may need to be adjusted.
Action
1. The Irrigation Amounts could be programmed too low. The total Irrigation Amount should be equal to or above peak historical ET values. See Appendix Determining the Irrigation Amount for more information about this setting.
2. The Minimum Run Time Limit lets you decide the smallest percentage of the watering cycle you will allow to run. Setting the Minimum Run Time Limit to 0% means that with each amount of ET received the ET Manager Cartridge will try to replace the water immediately even if it means running the Programs for only 1% of their scheduled time. Adjust the Minimum Run Time up (default setting is 80%).
To water the next cycle you may manually start the Program(s), or adjust the Moisture
Levels for the selected program(s) to 0.
1. The weather signal rainfall value may not correctly represent rainfall at your site.
Connect an optional on-site rain gauge (ETM-RG).
2. Check the location of your optional on-site rain gauge, make certain there are no obstacles blocking rain from entering the rain gauge.
3. Check the rain source to verify the ET Manager Cartridge is programmed to use data from the correct rain source (see page 19).
4. The Maximum Hourly Rain setting may be limiting the amount of rainfall applied to the Moisture Levels. Change the Maximum Rain to a higher amount to accept more rainfall in the Moisture Levels
5. The Saturation Allowance may be too low. Change the Saturation Allowance to a higher amount to accept more rainfall in the Moisture Level(s).
ET Manager Cartridge for ESP-LX Modular

Symptom
After a rainstorm my sprinkler system does not resume watering soon enough
It was raining and the sprinklers were running
Probable Cause
There are several reasons the sprinkler system may not resume watering soon enough after a rainstorm:
1. The rainfall received in the weather signal may not correctly represent rainfall at your site.
2. The rain source in the ET Manager Cartridge may be programmed incorrectly.
3. Effective Rain settings may need to be adjusted.
There are several reasons the sprinkler system may be watering during a rainstorm:
1. The rainfall received in the weather signal may not correctly represent rainfall at your site.
2. The rain source in the ET Manager Cartridge may be programmed incorrectly.
3. Rain cancel settings may need to be programmed.
Action
1. The weather signal rainfall value may not correctly represent rainfall at your site.
Connect an optional on-site rain gauge.
2. Check the rain source to verify the ET Manager Cartridge is programmed to use data from the correct rain source.
3. The Maximum Hourly Rain setting may be accepting more rainfall into the Moisture
Levels than the landscape is actually capable of accepting. Change the Maximum Rain to a lower amount to limit rainfall in the Moisture Levels.
4. The Saturation Allowance may be too high. The Saturation Allowance creates a limit to the amount of rain that can accumulate in the Moisture Level(s). Change the Saturation Allowance to a lower amount to limit the amount of rainfall that can accumulate in the Moisture Level(s).
1. The weather signal rainfall value may not correctly represent rainfall at your site.
Connect an optional on-site rain gauge.
2. Check the Weather Info for the last hour of rain to verify the rain data is being reported by your ET Manager Cartridge.
3. Check the rain source to verify the ET Manager Cartridge is programmed to use data from the correct rain source, if correct check the rain gauge for proper functionality
(you may need to contact your Weather Reach Signal Provider).
4. Program a 1 Hour Rain Cancel to stop watering until rain accumulations reach below the programmed Rain 1 Hour setting.
5. Program a Rain Cancel to cancel watering until rain accumulations reach below the programmed Rain Cancel setting.

Interrupt setting, the 24 Hour Rain Interrupt will clear.
Accuracy ..........................................................................57
The ET Manager Cartridge looks at the last two weeks of weather signals and reports the accuracy of the weather signal. An accuracy level less than 50% will create and Alert
Condition.
Clear Data ........................................................................ 49
If it becomes necessary, you may clear all records stored in the ET Manager Cartridge. Clearing Data will not change and settings, but will erase all weather information, paging history, interrupt history, and irrigation logs, and will automatically set your Moisture Levels to 0.
Counters ............................................................................1
The All Pages counter registers every signal received, the
Weather Region counter registers every signal received on the programmed Weather Region, the Rain Region counter registers every signal received on the programmed Rain
Region (if applicable), the Local Rain Tips registers every tip received.
Effective Rain Settings ...................................................41
Effective rain is the amount of rain that is an available source of water for the plant. When rainfall amounts and intensities are extreme, not all rainfall will stay within the root zone. To restrict the amount of rain recognized by the system, two effective rainfall limits should be programmed: Max Hourly
Rain and Saturation Allowance.
Elevation ......................................................................... 15
In order to calculate accurate ET for your location, your approximate elevation is necessary. To determine your elevation you may refer to the elevation of the nearest weather station, such information is available on the Signal
Provider Information Sheet and on the Resource CD.
ET Manager Cartridge for ESP-LX Modular
62
ET ....................................................................................... 1
An abbreviation for evapotranspiration which is a measurement of water that evaporates from the soil and transpires from a plant. ET represents the total moisture loss from the root zone.
ET Manager Programming Software (Model ETM-PS) ........15
The ET Manager Programming Software is a software program that simplifies ET Manager programming. The
ETM-PS allows you to connect your ET Manager Receiver to a personal computer to perform several key functions.
ET Manager Scheduler ................................................... 15
The Rain Bird ET Manager Scheduler software program uses sprinkler system capabilities and site specific information to help you prepare a watering schedule and determine ET
Manager Cartridge settings.
ET Source ......................................................................... 39
The ET Manager can be set to operate using either the hourly weather signal, or historical ET data.
Historical ET .................................................................... 15
This setting represents an average daily ET for each month.
If a problem occurs and the ET Manager Cartridge is not receiving the weather signal, it will continue to operate using historical ET settings as default ET. See your ET Manager
Cartridge Resource CD for a database of Historical ET data for your area.
63
ET Manager Cartridge for ESP-LX Modular
Historical ET is NOT set ................................................... 57
The ET Manager Cartridge uses historical ET values set by the user as a backup in the event weather signal service is not available. If no Historical ET has been programmed, this
Alert message is displayed.
Irrigation Amount ........................................................... 16
The amount of water in inches (or mm) applied to the landscape during each program start. The Total Irrigation
Amount is calculated by multiplying the number of program starts by the Irrigation Amount. Use the ET Manager Cartridge
Resource CD to determine your Irrigation Amount based on information about your sprinkler system and landscape.
Landscape Adjustment Percentage .............................. 38
The Landscape Adjustment Percentage is used to adjust for site-specific landscape needs for each Program. The
Landscape Adjustment Percentage is applied to the calculated ET, and affects the adjustment of current Moisture
Levels for each Program. As a general rule the Landscape
Adjustment Percentages should range between 60% - 100% for turf grass and 40% - 80% for shrubs.
Local Rain Gauge Input Failure Check Wiring .............. 57
If you are using a rain gauge to collect rain data and there is a problem with the input to the Rain Tip wire terminal, this message is displayed.
Look-Ahead Feature ....................................................... 35
If water days are limited the ET Manager Cartridge looks ahead each day to determine if watering should occur even though the Moisture Level has not met minimum levels.
Low Weather Signal Accuracy ........................................ 57
If data reception accuracy is less than 50% then the Low
Weather Signal Accuracy message is displayed.
Max Hourly Rain ............................................................. 41
The Maximum Hourly Rain is the maximum amount of rain that will be used in an hour to adjust the soil moisture level.
Maximum Run Time ........................................................ 35
The Maximum Run Time gives you the ability to decide the largest percentage of your watering cycle you will allow to be applied to your landscape. There may be instances where watering has been turned off and the Moisture Level in your landscape has dried out more than a regular watering cycle will be able to replace. In this situation the ET Manager
Cartridge will adjust the Seasonal Adjust percentage above
100% causing your sprinklers to run longer than their normally scheduled time. The Maximum Run Time may be helpful if there is a certain amount of time you want your watering to stay within.
Minimum Run Time ........................................................ 35
The Minimum Run Time gives you the ability to decide the smallest percentage of your watering cycle you will allow to be applied to your landscape. For example, if you set the
Minimum Run Time to 50%, then the ET Manager Cartridge will not allow watering until enough Moisture has been lost from the soil to run the Program(s) for half their normally scheduled time. Setting this percentage to a low number will mean that your ET Manager Cartridge will allow watering even if only a small amount of evaporation has occurred.
Setting this percentage to a high number will delay watering until more evaporation has occurred, providing oxygen to the roots which will encourage them to grow deeper, without sacrificing the health of the plant.
Moisture Level ................................................................ 25
The moisture level represents the current amount of moisture in your soil and is constantly changing due to evaporation
(ET), rain, and irrigation. The ET Manager Cartridge uses the
Moisture Level to determine the Season Adjust percentage set in the controller by the ET Manager Cartridge.
No Paging Signal Detected ............................................ 56
The ET Manager Cartridge periodically verifies the presence of the Paging Signal. If the paging signal is not detected after a period of time, this message will be displayed.

No Signal Service Activation Required Please Contact
Signal Provider ............................................................... 55
Your Weather Reach Signal Provider (WRSP) can send a “No
Signal Service” signal to cancel weather signal reception.
Typically this would happen only if the terms of the service agreement were not met. Subscription based weather signal service requires device activation by the Weather Reach
Signal Provider.
No Weather Signals have been received in the last 24
Hours ............................................................................... 56
If the ET Manager Cartridge does not receive weather data for 24 hours average this message will be displayed.
PGM X is at Wilting Point ................................................ 57
The ET Manager Cartridge computes the current Moisture
Levels for each Program. If conditions cause the Moisture
Level for a program to dry out to the negative Total Irrigation amount, this is considered Wilting Point and an Alert message is displayed.
Precipitation Rate ........................................................... 69
The rate at which water is applied to the landscape, or the precipitation rate, is measured in inches per hour.
Provider Interrupt ..........................................................55
The Weather Reach Signal Provider (WRSP) can send a signal to interrupt watering. This may be necessary during an emergency condition in the community requiring watering to be suspended to limit the demand on the community water system. As a service, your WRSP may also watch weather forecasts and choose to interrupt watering for expected conditions such as large rain storms. A Provider
Interrupt lasts for 24 hours. For information regarding a current Provider Interrupt, contact your Weather Reach
Signal Provider.
Radio Initialization Failure Press ET Manager Cartridge Reset ..... 58
The ET Manager Cartridge uses a radio to receive the weather signal. If the ET Manager Cartridge is experiencing radio initialization problems, this message will appear.

65
ET Manager Cartridge for ESP-LX Modular
Rain Region ..................................................................... 43
Like the weather region number, a rain region number represents a rain gauge accessed by the Weather Reach
Signal Provider who then broadcasts the rain region data.
The user programs the rain region number to correspond to a rain region that closely represents rainfall for the location of the ET Manager Cartridge. To determine if a Rain Region is available in your area, refer to the Signal Provider Information
Sheet for your signal provider.
Rain Source ..................................................................... 21
The rain source is the source of rain data for the ET Manager
Cartridge. Rain data can come from 1) the hourly weather signal, 2) optional on-site rain gauge (either 1 mm / tip or
.01” / tip), 3) rain region.
Saturation Allowance ..................................................... 42
The amount or rain it takes to saturate the soil after satisfying the total irrigation amount before run-off occurs.
Unique Saturation Allowance settings can be made for each program and are typically programmed as half the total irrigation amount.
Serial Number.......................................................................
The serial number of your ET Manager Cartridge can be found on the ET Manager Receiver Cable, and is also displayed at the bottom of the ET Manager Settings screen.
Signal Kc .......................................................................... 51
Signal Kc (or Signal Crop Coefficient) is used by the Weather
Reach Signal Provider to modify ET to a specific crop and can change over the year due to seasonal conditions. You can choose to “Use” or “Ignore” this adjustment. For information on the signal crop coefficient, contact your Weather Reach
Signal Provider.
Signal Provider Code ......................................................15
The ET Manager Cartridge must be programmed to receive information from your local Weather Reach Signal Provider
(WRSP). A Signal Provider Code is unique for each WRSP and is necessary for an ET Manager Cartridge to receive a weather signal. The code consists of 10 different numbers labeled A thru J. For a map of available WRSP and their Signal Provider
Codes visit www.rainbird.com/wrsp.
Signal Provider Code is NOT set ....................................57
If the ET Manager Cartridge has been installed but not programmed with a Signal Provider Code, this Alert message appears.

Temperature Interrupt ...................................................33
If the hourly weather signal contains air temperatures that reach or are below the Temperature Interrupt setting, watering is canceled. Once the air temperature rises above the programmed interrupt setting, as received in the hourly weather signal, the Temperature Interrupt will clear.
Units English/Metric ....................................................... 47
The ET Manager Cartridge can calculate and display values in either English or Metric units.
Weather Information ......................................................29
You can view detailed weather information as received by the ET Manager Cartridge in the most recent weather signal.
Weather Reach Signal Provider (WRSP) ........................15
The role of a Weather Reach Signal Provider (WRSP) is to retrieve weather information from local weather stations and send the weather signal to an ET Manager Cartridge.
Weather Region ..............................................................15
The weather region number represents a weather station assigned by the Weather Reach Signal Provider (WRSP).
The user programs the weather region in the ET Manager
Cartridge to correspond to a weather station that closely represents the location of the ET Manager Cartridge.
For a map of available weather stations from a local WRSP visit www.rainbird.com/wrsp.
Weather Signal ................................................................ 19
A Weather Reach Signal Provider retrieves weather information from local weather stations. The information is broadcast as a weather signal via a paging radio frequency to your ET Manager Cartridge. The weather signal contains the most recent weather conditions including: solar energy, temperature, wind, humidity, and rainfall.
Wind Adjust .....................................................................53
The wind speed measurement included in the weather signal can be scaled by a percentage to compensate for variations in prevailing conditions. When this setting is at 100% the ET
Manager Cartridge will use the exact wind measurement as it is received in the hourly weather broadcast.
Wind Interrupt ................................................................33
If the hourly weather signal contains wind speeds that reach or exceed the Wind Interrupt setting, watering is canceled.
Once the wind speed decreases below the programmed interrupt setting, as received in the hourly weather signal, the Wind Interrupt will clear.

Appendix
Determining the Irrigation Amount
Irrigation Amount Setting
There are several ways to determine the Irrigation Amount setting:
1. Use the ET Manager Scheduler software found on the ET Manager Cartridge resource CD to determine all settings for your ET Manager Cartridge and LXM controller. The scheduler software requires site information such as: root depth, soil type, and sprinkler type, nozzle, pressure, and spacing information to calculate the precipitation rate of each zone. Catch can collections can also be entered into the scheduling software to calculate you precipitation rate and distribution uniformity.
2. Use the sprinkler head manufacturer’s expected precipitation rate (typically expressed in inches per hour). Perform this calculation for each zone to determine the setting for each Program:

3. Perform a Catch Can Test for each valve. A Catch
Can Test is done by placing ”cans” with sides that are straight up and down in various locations throughout the zone, then run the zone for the entire scheduled run time. Measure the amount of water in each “can” and average the amounts. This average measurement is your Irrigation Amount.
