Selecting Control Options  
A set of eight DIP switches, located beneath the upper left corner of the control panel (as illustrated below)  
is provided for the selection of optional control characteristics. Power to the controller must be turned Off  
and the control panel removed from the cabinet in order to make switch position changes. When power is  
switched on, the controller will automatically reconfigure to the new switch settings (with the exception of  
switch 5). See *Note below.  
The controller is shipped from the factory in the following configuration:  
Switch 1 ON and Switch 2 ON Enables the controller to run eight programs concurrently.  
Option Switch 1 OFF and Switch 2 ON Enables the controller to run only six programs  
concurrently.  
Option Switch 1 OFF and Switch 2 OFF Enables the controller to run only four programs  
concurrently.  
Option Switch 1 ON and Switch 2 OFF Enables the controller to run only two programs  
concurrently.  
Switch 3 ON Time is displayed in a.m./p.m. format.  
Option Switch 3 OFF Time is displayed in 24-hour format (00:0023:59)  
Switch 4 ON Pump output activates at the same time as station output.  
Option Switch 4 OFF Pump output starts 5 seconds prior to station output. (Enables pump to reach  
pressure prior to station operation.)  
Switch 5 ON Active day change occurs at midnight (12:00 a.m.[00:00])  
Option Switch 5 OFF Day change occurs at 6:00 a.m. (06:00)  
*Note: This change requires initialization to activate. See page 14 for initialization procedure.  
Switches 6, 7 & 8 are non-functional.  
To change the DIP switch positions:  
1. Switch the power Off at controller power supply.  
2. Remove the timing mechanism from the top of the pedestal cabinet. (The cables attached to the timing  
mechanism can remain connected for this procedure).  
3. Locate the DIP switches mounted on top left corner of timing mechanism PCB.  
4. Using a pen tip or small screwdriver, reset the DIP switches as required. (Do not use a pencil for this  
procedure. Loose graphite from the pencil can damage the switch mechanism).  
5. Reinstall the timing mechanism and switch on the power.

Before Programming the Controller…  
Please note the following important information before programming the Network LTC Plus con-  
troller for the first time. Although the controller is quite easy to program, it does have some pro-  
gramming and operating characteristics which will be helpful to know before starting.  
*If power is interrupted to the satellite within one minute of a programming entry, the controller memory  
will be initialized (erased) when power is restored.  
An audible beeptone occurs whenever a control panel key is pressed sufficiently. If the tone is not  
emitted, the keys function will not be recognized.  
Programming can only be accomplished in the Central or Stand Alone control modes.  
The  
and  
(cursor keys) are used to navigate to the various program elements of the displays.  
When an element is selected, it begins flashing. Remember, a program element must be flashing  
before it can be changed.  
The  
and  
(scroll keys) are used to scroll forward or backward through the program element  
values Holding either of these keys down for more than two consecutive seconds will initiate rapid  
scrolling.  
ENTER  
The  
(Enter/Start key) must be pressed to enter a program change into memory.  
(function select) key to select the Time/Day mode.

To exit a programming procedure, press the  
During programming, the controller will automatically revert to Time/Day mode if a control panel key is  
not pressed for one minute.  
About the Controllers Memory…  
The controller utilizes a special Super Capcapacitor which stores enough power to maintain the current  
time/date and the currently active program information for approximately 30 minutes. The controller will be  
otherwise inactive during the power outage. In most circumstances, the user-defined program information is  
unaffected by a loss of power and is stored in memory for several years. (See * above). When power is  
restored, any automatic programs operating prior to the power failure will resume from the point of interrup-  
tion. Any manually started programs operating prior to the power failure will be canceled. Any automatic start  
times originating from the satellite or the central during the power failure will be ignored. In regions with fre-  
quent power interruptions, an optional lithium battery can be installed which will sustain real time and cur-  
rently active program information for approximately 90 days of continuous duty. See Battery Installationon  
page 16 for more information.  
Set Satellite Operating Mode  
Selecting one of three operating modes determines how the satellite will operate.  
Central mode enables two-way communication between the satellite and the central controller. The satellite  
receives all operating commands (including the current time and day) from the central. No additional pro-  
gramming is required at the satellite. To operate in the Central mode, the satellite only requires an address  
which enables the central to locate it on the communication path. See Set Satellite Addresson page 13.  
Stand Alone mode enables the satellite controller to operate independently from the central. Any data  
downloaded from the central will be ignored by the satellite while in this mode. However, information regard-  
ing field status and manual satellite operations will be uploaded to the central. When operating as a stand-  
alone controller, the Network LTC Plus maintains 16 independent watering programs. Each program is given  
specific operating information consisting of: Start Times when and how often the program will start,  
Active Days the daily watering routine in either a 14-Day Calendar or 29-Day Interval schedule, and Run  
Times the operating duration time of each station assigned to the program. During a program event,  
stations assigned to the program operate one at a time in numerical sequence.  
Off mode terminates and prevents all automatic and manual controller operations.  
If programming the satellite for stand-alone operation, we recommend that you first plan out your irrigation  
schedule using the Program Data Reference Form provided on the back cover. Make photocopies of the  
form for each program you intend to use. Organizing your program information in this way will provide a  
complete overview of your automatic irrigation schedule and simplify the programming task. After the forms  
have been filled in, keep them with the satellite for future reference.

Set Active Day Watering Schedules  
The active watering days for each program can be chosen using a Calendar schedule or an Interval  
schedule. The Calendar schedule enables active days to be selected within a 14-day (two week) cycle. The  
Interval Schedule enables active days to be selected by a specific interval, such as every day, every-other  
day, every-third day and so on up to every twenty-ninth day.  
Select the active watering days for each program using either a Calendar schedule (below) or an Interval  
schedule (on page 8).  
Note the following programming characteristics:  
Only one watering day schedule (Calendar or Interval) can be utilized for each program.  
To prevent automatic operation of any program, all days in a Calendar Schedule can be deleted or

Interval Schedule  
Scheduling active days by Interval enables a program to operate on a specific routine such as, every other  
day, or every fourth day, without regard to actual calendar days.  
The Interval schedule consists of two programmable numbers: The Interval Reference and the Interval Day.  
The Interval Reference number (01 29) determines how often an active watering day will occur. For  
example, entering 01 equals watering every day, 02 equals every other day and so on up to 29 for watering  
every 29th day. The Interval Day number (01 29 and Off) indicates when an active watering day will occur.  
The Interval Day number automatically decreases by one at the day changeover. An active watering day will  
occur when the Interval Day number is 01. As the day change occurs at the end of the active watering day,  
the Interval Day number will automatically update to display the number of days until the next active  
watering day.  
During initial programming, the Interval Day number can be set at any point in the interval to establish the  
position of the interval within the week or month. For example, you may select a 6-day interval (watering  
every sixth day) but choose to start the interval tomorrow by entering an Interval Day number of 02. After  
one day has elapsed, the interval will begin and the day will be active. At the end of the active day, the  
Interval Day number will reset to 06, indicating six days until the next scheduled watering.  
Note: The Interval Day number cannot be greater than the interval reference number. If attempted, the  
Interval Day number will automatically be reduced to equal the the Interval Reference number when the  
Enter/Start key is pressed.

Set Satellite Address  
The LTC satellite requires a unique address for identification by the central LCM within the network system. The  
address consists of a group number (1 50) and satellite number (1 500). A combination of up to 500 satellites  
may be defined. Satellites may only be assigned to one group. However, the same satellite number may be  
used for satellites in different groups. For example, satellite 001 in group 01 has a different address than satellite  
001 in group 04. The satellite address is based on the combination of the group and satellite numbers.  
Use the following procedure to assign the satellite address.  
1. Press  
to select Address indicator The displays show the  
current group and satellite numbers. The default address is group  
50, satellite 500.

Set Percent Adjust  
This feature enables the run time of all stations assigned to a program to be adjusted by the same  
percentage up or down in 1% increments. Run time percent adjustments can be applied to individual  
programs and/or globally to all programs.  
Note the following Percent Adjust characteristics:  
Adjustable from 10% to 250% (100% is neutral position).  
Adjusted station run time is displayed during program operation and while setting station run times.  
(See Note on page 5 regarding adjusted run time display.).  
% adjust values will be reset to 100% when operated in the Central control mode.  
Global adjust (P0) is applied to all programs in addition to individual program % adjust value.  
Example: A 40 minute run time with a 50% Individual program adjust value and 50% Global adjust value  
equals 10 minutes adjusted run time (40 x 50% = 20 x 50% = 10).  
1. Press
