COMMON TO ALL VALVES
Remove the lower cover of the DDC controller. Place the unit on the wall using the
top screw slot. Level the controller, then insert screws into the two lower screws
holes under the terminal block. Connect the solenoid wires to the terminal block.
Connect one wire from the solenoid to its respective station number on the
terminal block and the other wire to the C-common terminal. Finally, connect the
transformer wires to the 24 VAC terminal.
9 VDC battery . The 9 volt battery compartment is located between the sensor
terminal and the 24VAC terminal. The 9 volt battery powers the LCD display in the
absence of AC power and allows “Arm Chair Programming”. Program information
is retained during power outages by an on-board lithium battery.
Note: Only after all the wiring is completed and checked should the
transformer be plugged into AC power.

SENSOR
To connect a rain sensor, remove the jumper wire from the sensor terminal and
connect one wire of the Toro Rain Switch to the C-common terminal and the other
wire to the N.C. (normally closed) terminal. As soon as the Rain Switch contacts
change from the N.C. position to the N.O. (normally open) position, irrigation will
be suspended. Irrigation will resume as soon as the Rain Switch dries and its
contacts return to the N.C. position.
When irrigation is suspended due to the Rain Switch, the display shows: OFF
NOTE: When using the Toro Rain Switch, follow the Basic Connection
Installation Instructions.

until display shows OFF.
Press DIAL to advance to the “% Scaling” position.
-7-
Dial position: % SCALING (Seasonal adjust)
In this dial position you can increase or decrease the RUN TIME of all
stations in that program by percentage scaling from 0% to 200% in 10%
increments.
% SCALING
Press PROG to select the program you wish to scale.
Press +/ON or -/OFF to change.
The Initial RUN TIME represents 100%. The controller will record the change, i.e.,
if a program was scaled down to 80%, next time you enter this dial position the
display will show 80%.
To set a program to "OFF"
If you wish to stop irrigation of a program, set percentage scaling to 0%.
The display will show that program is OFF.
To resume normal operation of that program, Dial to "% SCALING" and increase
the percentage to your desired value. Increasing to 100% will set RUN TIME to its
original value.
Press PROG to select the program.
Press DIAL to advance to MANUAL.
MANUAL
Dial position: MANUAL
The MANUAL mode allows immediate customized irrigation on one or more
zones. You can set an individual RUN TIME for each of the stations you wish to
start manually. The controller has a "programmable manual" function, so if you
manually operate more than one station, they will open in sequence.
Press +/ON or -/OFF to set the station RUN TIME.
Press NEXT to advance to next station.
To turn ON the 1st station in the sequence:
Press DIAL to AUTO-RUN position.
Press -/OFF (in AUTO-RUN position) to turn OFF the sequence.
All stations with a manually programmed RUN TIME will be displayed. Operating
stations will flash and the display will show the remaining RUN TIME of the station
(count down).
Press DIAL to advance to SEMI-AUTO.

Dial Position: SEMI-AUTO
SEMI-AUTO
The SEMI-AUTO mode allows the immediate start of an entire
program (A, B or C). When using the SEMI-AUTO feature, the DDC will
essentially override the normal start time and begin immediately. Using
SEMI-AUTO does not affect the previously scheduled run times. They will begin as
programmed once the SEMI-AUTO feature has completed its cycle.

Self Diagnostic Circuit Breaker
The Toro DDC controller will detect a short circuit caused by a defective solenoid
or a short in the valve wiring. As soon as the short is detected, that station is
turned OFF. The next station in the watering sequence is turned ON and the
shorted station number icon together with OFF will start flashing.
NOTE: If the short is in the master valve, only OFF will start flashing.
Verification of a short circuit can be done in the SEMI-AUTO dial position
Press NEXT to the flashing station.
Press -/OFF to stop the flashing.
Press +/ON to turn ON the station.
If the flashing appears once again, check your wiring to this particular station. If
the wire connection is fine, the cause of the short is the solenoid, which should be
replaced.
NOTE: The 9 VDC battery must be installed for the proper operation of the
diagnostic circuit breaker.
About the DDC memory
This controller is equipped with "on board" back up battery that will keep the
program memory for a few years in case power is not available.
If you wish to program the controller without connecting it to AC power, install the
9 volt alkaline battery.
The 9 volt battery will turn on both displays and programming is possible.
Power failure indication
During a power failure the “24V” will start flashing and will continue until AC power
is restored or the 9 volt battery is exhausted. A blank display indicates that there
is no AC power and the 9 volt alkaline battery, if installed, is dead.
