INSTALLATION INSTRUCTIONS: INDOOR MODELS
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. Next install the battery.
NOTE: The 9 VDC battery must be installed for the proper operation of the
controller. The 9 volt battery compartment is located between the sensor
terminal and the 24VAC terminal. A standard 9V battery is required for Armchair
ProgrammingTM and to maintain clock time during an extended power loss.
Note: Only after all the wiring is completed and checked should the
transformer be plugged into AC power.

INSTALLATION INSTRUCTIONS: OUTDOOR MODELS
Remove the lower cover of the DDC controller by sliding it down. Place the unit on
the wall using the top keyhole screw slot. Level the controller, then insert screws
into one or more of the three lower screws holes at of the cabinet bottom. Drive
the screws through the plastic flashing that keeps the cabinet weather resistant. If
installing the controller on drywall or masonry, install screw anchors to prevent the
screws from loosening. Connect the solenoid wires to the terminal block through
the 12mm (1/2”) hole in the right side of the cabinet bottom. If the solenoid wires
are being installed in conduit, there is a knock-out on this hole that will accept a
24mm (1”) male conduit adapter. Connect the wires as shown for the indoor
model. Last, connect the power wires.
Warning: AC power wiring must be installed and connected by
qualified personnel only. All electrical components and installation
procedures must comply with all local and national electrical codes. Some
codes may require a means of disconnection from the AC power source
installed in the fixed wiring and having a contact separation of at least 3mm
(0.120”) in the line and neutral poles. Make sure the power is OFF prior to
connecting the controller.
The hole on the left side of the cabinet bottom accepts a 12mm (1/2”) male conduit
adapter. Route the power and equipment ground wires from the power source,
through the conduit and into the transformer connector compartment.
NOTE: The terminal block accepts wire size up to 4mm (12 AWG).
Remove 10mm (3/8”) of insulation from the wire ends. Using a small flat bladed
screwdriver, secure the wires as follows: Line or Line 1 (L1) to L, Neutral or Line 2
(L2) to N and Equipment Ground to G. Install compartment cover. After first
installing a 9 VDC battery, apply AC power to the controller.
9 VDC battery. The 9 volt battery compartment is located below the 24VAC
terminals.
A standard 9V battery is required for Armchair ProgrammingTM and to maintain
clock time during an extended power loss.

Sensor connection and operation:
To connect a rain sensor, remove the jumper wire from the sensor terminal and
connect one wire of the Toro RainSensorTM to the C-common terminal and the other
wire to the N.C. (normally closed) terminal. As soon as the Toro RainSensorTM
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 Toro
RainSensorTM dries and its contacts return to the N.C. position.
When irrigation is suspended due to the Toro RainSensorTM, the display shows:
OFF
NOTE: When using the Toro RainSensorTM, follow the Basic Connection
Installation Instructions supplied with the Rain Sensor.

Dial position: SEASON ADJUST/ADJUST WATER
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. Watering percentage is adjusted by month with
the default setting being 100% of set runtimes. This water
management feature allows you to stop irrigation for the months not requiring
irrigation and ramp up the irrigation times as the irrigation season advances.
Press PROG to select the program you wish to percentage adjust.
The display will show 1:10%. This is January, month one, and it is set at 100%.
