Congratulations. You have purchased the easiest-to-use landscape control system
available today. Although it is possible to install and program your Rain Dial
®
controller
with little or no instructions, we strongly recommend that you read this guide first.
Your controller contains:
Specifications
Transformer voltage input: 120 V a.c., 60 Hz, 0.5 amps (Note: 230 or 240 V a.c., 50 Hz
available for international models)
Controller voltage output: 24 V a.c. at 1.0 amp total maximum output; 0.5 amps per
station maximum.
Operating temperature range: 32°F to 140°F (0°C to 60°C)
Battery back-up: One 9-volt alkaline battery (supplied by user)
• Modular design allows:
– easy access to valve wiring terminals and battery.
– Simple snap-out removal of module for convenient “anywhere” programming or
service without disturbing installation.
– Easy modular upgrade to as many as 12 stations.
• Short circuit detection overrides an electrical malfunction of a valve, identifies it, and
allows the other valves to water.
• Default “fail-safe” program runs all valves for 10 minutes daily in case of program loss.
• Rugged, weather resistant, lockable case comes with 2 keys (outdoor models only).
• 3 Programs for different watering requirements such as trees, lawns and flower garden.
• 3 start times for each program, if desired.
• “Skip day”scheduling for interval watering from 1 to every 15 days.
• Fully automatic, semi-automatic or manual operation.
• Built-in circuit protection to protect the controller from power surges.
• LCD Display shows current operation, including the time of day.
• Live programming allows program to be set or changed at any time, even during
watering.
• Off (or rain) setting stops all watering cycles without disturbing programs.
• Battery back-up saves programs and keeps time during remote programming or
power outage.

• Mounting template
Selecting the proper installation site for the controller is essential to safe and reliable
operation. The controller should be installed on a vertical wall or other sturdy structure
near a grounded power source. For easy operation and better view of the display, install
the controller so that the display is at, or slightly below, eye level.
CAUTION: Do not connect to power until after the valves are connected. Indoor
model controllers are not weather resistant and must be installed indoors or in a
protected area.
Installing the Indoor Model Controller
Step 1 - Using the mounting template, mark the location of your Rain Dial in an area
protected from weather, such as the garage, and within 5' (1.52M) of a 120 V
a.c. outlet (230 or 240 V a.c., 50 Hz for international models). Do not install on
the same circuit with a high power user such as a refrigerator or air conditioner.
Step 2 - Drive a #10 screw into the wall stud, leaving about 1/4" (6.35mm) exposed to
slip into the keyhole slot on the back of the controller.
Step 3 - Open the door to your controller cabinet and swing open the control module by
flexing the release tab to the right.
Step 4 - Use the two provided screw holes to secure the controller with two additional
screws. Use wall anchors or toggle bolts if wall is hollow. See Figure 1.
Installing the Outdoor Model Controller
Step 1 - Use the mounting template to locate the two mounting holes. Although you can
locate your outdoor controller anywhere, it is best to avoid direct exposure to
sprinkler spray. Since this device is “hard wired,” keep in mind that you must run
electrical cable to it.
Step 2 - Locate the controller over the area marked with the template, then drive a #10
screw into the wall stud, leaving about 1/4" (6.35mm) exposed to slip into the
keyhole slot on the back of the controller.
Step 3 - Open the door to your controller cabinet and swing open the control module by
flexing the release tab to the right.
Step 4 - Use the two provided screw holes to secure the controller with two additional
screws. Use wall anchors, toggle bolts or other appropriate fastener when
attaching to other than wall studs. See Figure 1.

Installing a standard 9-volt alkaline battery will preserve the controller’s time and program
in the memory during a power outage.
CAUTION: Batteries contain hazardous material. Always handle and discard
batteries properly in accordance with the battery manufacturer’s recommendations.
Step 1 - Open the door to your controller cabinet and swing open the control module by
flexing the release tab to the right.
Step 2 - Open the battery compartment located at the top rear of the control module.
Step 3 - Insert a standard 9 volt battery onto the battery clip.
Step 4 - Replace the battery compartment lid and close the control module.
See Figure 1 on page 4.
CAUTION: Before connecting the
valves to the controller, make sure
that the power supply is unplugged
(indoor model) or disconnected
(outdoor model).
Step 1 - Open the door to your controller
cabinet and swing open the
control module by flexing the
release tab to the right.
Step 2 - Attach one lead from each valve
to a single common wire. Route
the common wire through the
conduit opening and secure it to
the “VC” (valve common) terminal
of the terminal board.
Step 3 - Route each remaining valve wire
through the provided conduit
opening located at the bottom of
the controller cabinet. Secure
each valve wire to the desired
numbered terminal. See Figure 2.
CAUTION:All wiring splices must be waterproofed to prevent short circuit and
corrosion. Agrease cap or similar waterproofing method can be used to insulate
each wire splice connection.
Note: This controller is designed to work with 24 V a.c., 5VA solenoid operated valves. A
maximum of two solenoids per terminal may be used, and no more than three solenoids
should be on at any time. This includes the master valve and/or pump start, if one is being
used. Load requirements should not exceed 1.0 amp maximum current draw.

When a pump start relay or a master valve is to be operated by the controller, a
compatible device must be used. The master valve must be equipped with a 24 V a.c.,
0.2 amps, 5VA solenoid. If using a pump relay, it should have a nominal coil voltage of 24
V a.c. at 0.25 amps maximum. The controller should not be installed within 5' (1.52m) of a
pump or pool equipment.
Step 1 - Route the relay or the master valve wires to the controller using the same
conduit opening used for the valves. See Figure 2 on page 5.
Step 2 - Connect one wire to “MV/PUMP” terminal and the other to “VC” terminal.
CAUTION: If you are using a pump start circuit, the fail-safe program will activate the
pump for each valve for 10 minutes on Program A. If all valves are not being used,
the pump will run against a “dead head” on each unused valve. This can damage the
pump. To avoid this, connect a jumper wire from the unused valve terminal to a valve
terminal that is in use.
Power Connection for Indoor Model
After you have installed the controller securely and made all necessary valve connections,
route the two leads from the plug-in transformer through the bottom conduit opening and
connect to the “24 V AC” terminals. Close the control module and plug the transformer into
a 120 V a.c., 60 Hz power source (230 or 240 V a.c., 50 Hz power source for
international models). The display should flash “12:00 PM”.
Power Connection for Outdoor Model
Outdoor controllers have a built-in transformer which must be connected directly to a
grounded, 120 V a.c. power source (230 or 240 V a.c., 50 Hz for international models).

Connecting the Power Supply
Pump Start Relay or Master Valve Connection
Warning: All electrical components must meet applicable national and local
electrical codes including installation by qualified personnel.
On outdoor models, these codes may require an external junction box mounted on
the transformer 1/2" NPT nipple and a means in the fixed wiring of disconnecting
AC power having a contact separation of at least 0.120" (3mm) in the line and
neutral poles.
Ensure the AC power source is OFF prior to connecting to the controller.
The wire used for connection to the controller must have insulation rated at 105° C
minimum.
