GENERAL INFORMATION
This section contains general information on:
•How the backup system works
•How the electronic circuit breaker works
•How the sensor feature works
HOW THE BACKUP SYSTEM WORKS
The Total Control uses non-volatile memory to store watering programs. This type of memory prevents the watering program information from becoming lost in the event of a power failure. An additional benefit of non-volatile memory is that a factory-installed backup program is not necessary, thereby avoiding the potential for unplanned operation.
Because the current time and date are always changing, only the most recent date can be saved in non-volatile memory. Therefore, a battery is required to maintain the correct time and date in the event of a power failure. A 9-volt alkaline battery (not provided) will maintain the correct time and date during power failures up to 90 days. In a typical installation, the battery should last from two to four years before replacement is necessary. Once the battery or AC power is connected, the controller can be fully programmed for operation.
Note: For operation of the valves, AC power must be applied.
To install the battery: |

General Information |
HOW THE ELECTRONIC CIRCUIT
BREAKER WORKS
The controller is equipped with an electronic circuit breaker. If the controller detects a short circuit, the affected station(s) will be turned off automatically. The display will then flash “SHORT” and the shorted station number or “MASTER VALVE.” The controller continues to automatically water the other stations and the following watering programs until the shorted station is repaired. The program will be cancelled if the master valve circuit is shorted. Each automatic start will attempt another cycle and retest the short-circuited valve.
Listed below are the most common conditions which will activate the electronic circuit breaker. After correcting the problem, return the controller to normal operation as follows:
1. Set the dial to one of the following positions: Run 
,
Manual-Single Station or Manual-Program Cycle.
2.Press the OFF button to return the controller to the normal operating mode.
Condition: The word “SHORT” displays with one or more station numbers.
Diagnosis: One or more stations are shorted.
Solution: Check the wiring of the displayed stations for the cause of the shorted condition. Repair valve(s) and/or wiring as needed.
Diagnosis: Too many valves operating at the same time causing an overload condition.
Solution: Check watering programs for concurrent station operation. Include master valve/pump start relay if used. Maximum total output is 24 V a.c. at 1.25 amps. Reduce the number of stations running at the same time.
Condition: The word “SHORT” displays without any station numbers.
Diagnosis: A short circuit has occurred with a time duration too short for the controller to determine the station.
Solution: Check all valve wiring for breaks in the insulation which may cause a station output to short to common.
Diagnosis: A transient power surge spike has occurred. Solution: Reset the controller.
Diagnosis: A short or overload occurred on one watering cycle but was no longer there on a subsequent cycle.
Solution: Check for loose and/or exposed valve wiring.

HOW THE SENSOR FEATURE WORKS
The Total Control is equipped to operate with an optional rain sensing device (rain switch) to prevent automatic controller operation during rain.
The rain switch is a simple device, typically installed on a roof overhang or stationary structure exposed to rainfall and full sun, and shielded from irrigation spray.
When rain occurs, the normally-closed rain switch senses the moisture and opens the valve common circuit, effectively preventing all output to the field. The electronic programming portion of the controller is isolated from the rain sensor switch, and continues to operate as programmed. When rain stops and the rain switch returns to its normally-closed state, the valve common circuit is restored, enabling watering to resume as scheduled.
A two-position sensor switch (see item 18 on page 3) is provided to enable you to easily bypass operation of the the rain switch at any time. If you choose to disregard rain switch input, place the SENSOR switch in the Bypass position. To enable rain switch operation, place the Sensor switch in the Active position.
IMPORTANT: If a rain switch is NOT connected to the controller, the SENSOR switch MUST be in the BYPASS position to enable controller operation.
The controller will not operate automatically or manually if the SENSOR switch is in the ACTIVE position without a rain switch connected.

PROGRAMMING THE
CONTROLLER
This section covers the following topics:
•Getting started
•Setting the current time and date
•Erasing any prior programs
•Setting the station run time
•Selecting Master Valve/Pump Start on/off
•Setting the program start times
•Selecting the days to water
GETTING STARTED
PREPROGRAMMING THE CONTROLLER
The unique design of the Total Control enables you to easily remove the control module from the cabinet for convenient programming while in the comfort of your home.
To take advantage of this feature, unlatch the control module and swing it outward. Disconnect the ribbon cable, then simply unclip the module from its support frame. Now, by installing a 9-volt alkaline battery (as shown on page 4), you can program and review your watering schedules and have the controller ready to operate immediately upon completion of the installation procedures.
Note: To extend battery life, the display will automatically dim after two minutes of inactivity. To restore the display, simply turn the function dial to any position. A fresh battery will maintain the current time and date for over 2000 hours of continuous duty. The program memory is non-volatile and does not require a sustaining power source for retention.
WHAT IS A WATERING PROGRAM?
A watering program is basically a small set of instructions which tells the control module when to start a watering cycle, which stations to operate during the cycle, which days the cycle will be active and how long each station will operate during the cycle. The Total Control has four independent watering programs available for your use. Although only one program is required to operate your controller, using separate programs enables you to optimize the amount of water being applied to different areas of the landscape. For example, you might use one program to water lawns in full sun every day. Another program could be used to water lawns in partial shade only on Monday, Wednesday and Friday. Trees and shrubs

|
using drip irrigation could run on a separate program once every two weeks. |
|
|
The garden area requirements might include watering every other day. |
|
|
To take full advantage of the programming options available, it is |
|
|
important to first understand how the controller works during operation. |
|
|
The following section explains what a watering cycle is and provides a |
|
|
basic example of how multiple programs can be set up. |
|
|
WHAT IS A PROGRAM WATERING CYCLE? |
|
|
When a watering start time is selected, that time becomes the beginning |
|
|
of an automatic watering cycle. A watering cycle operates each station |
|
|
assigned to the program, one by one, in numerical order. |
|
|
In the following example (also shown on the sample watering plan on |
|
|
page 9), we have set up Program A to start at 2: 00 a.m. and again at |
|
|
3:00 a.m. on a 1-day interval (every day). Stations 1, 2, 4 and 5 are front |
|
|
and back yard lawn areas which get full sun throughout the day. Each |
|
|
station will run for 10 minutes per watering cycle, for a total of 20 |
|
|
minutes run time per day. Stations 3, 6 and 7 are lawn areas which are |
|
|
shaded during the afternoon hours. These areas require less water, so we |
|
|
have assigned them to Program B and programmed them to run once for |
|
|
20 minutes on a 2-day interval (every other day). |
|
|
At 2:00 a.m., Program A watering cycle starts. Station 1 turns on, runs for |
|
|
10 minutes, and shuts off. Station 2 turns on, runs for 10 minutes, and |
|
|
turns off. Stations 4 and 5 operate sequentially in the same manner, each |
|
|
running for their set run time. When Station 5 shuts off, the watering |
|
|
cycle is completed for the first start time. At 3:00 a.m., the watering cycle |
|
|
starts again and repeats the same station-by-station watering sequence. |
|
|
Note that we have 40 minutes total operating time per cycle in |
|
|
Program A. If we had set the next start time at 2:30 a.m., the start time |
|
|
would have been delayed until 2:40 a.m., enabling the first cycle to finish |
|
|
as programmed. This function is called “start time stacking”, and can |
|
|
occur within each program. |
|
|
Watering programs, however, operate independently, which means that |
|
|
two or more programs can run simultaneously. In our example, |
|
|
Program B will also start at 2:00 a.m. Therefore, Stations 1 and 3 will |
|
|
turn on at the same time, and Station 2 will turn on while Station 3 is |
|
|
running. This feature enables more watering to be completed within the |
|
|
prime “watering window”, which is generally between Midnight and |
|
|
6:00 a.m. |
|
|
Note: When scheduling watering programs to run simultaneously, it is |
|
|
important to ensure the water supply has sufficient pressure and volume |
|
|
to maintain optimum sprinkler performance. |
