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:
1. Unlatch the hinged control module
assembly and carefully swing it
outward to open.
2. Locate and remove the battery
compartment cover from the lower
back side of the module. See Figure 3.
3. Connect a 9-volt alkaline battery to
the battery clip terminals.
4. Insert the battery into the
compartment and reinstall the battery compartment cover.
Caution: Batteries contain hazardous material. Always handle and
discard batteries properly in accordance with the battery
manufacturer’s recommendations.

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 WO RKS
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.

• 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 mo dule 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.
