Controller Installation

For safe, reliable operation, select an installation site which is:

• Weather protected.

• Within 4 ft. (1.2 m) from a grounded 110 VAC, 60 Hz outlet which is not controlled by
a light switch or utilized by a high current load appliance, such as a refrigerator,
air conditioner or garage door opener.

• Accessible to the sprinkler control valve wiring and optional accessory wiring.

Step 1 – Use the Screw Location Template on the back page to mark the screw locations.

Use a level to align the two screws horizontally. Install two screws, 5 inches
(12.7 cm) apart, into the wall at eye level. Leave the screw extended approximately

1/4 inch (6 mm) from the wall to accommodate the controller case.
If installing into drywall or masonry, install proper screw anchors.
Step 2 – Hang the cabinet using the back panel’s keyhole slot. Make sure the cabinet slides

down securely onto the screws.
Step 3 – (Optional) Remove the controller’s access panel and install a center mounting screw.

Tighten securely.

Battery Installation

The Lawn Master II maintains the programmed schedule and its
time and date by using a 9V battery backup. In the event of a
power outage and the 9V battery is not installed or very low in
power, the controller will reset the date and time to the default
01-01-2007 and 12:00am. Any scheduled watering that is
programmed in the Lawn Master II will also be lost.

Replace the 9V battery yearly to assure that the current

time, date and scheduled programs are retained.

IMPORTANT! Check the controller’s scheduled watering

program after every power outage to prevent interruption to your irrigation
system’s activity.

Step 1 – Remove the controller’s lower panel cover to access the battery compartment.

Step 2 – Install the 9V battery to the battery plug.

Step 3 – Secure the battery into the compartment.

Step 4 – Reinstall the lower panel cover.

Power Connection

Step 1 – Remove the controller’s lower panel cover

to access the power supply terminals.
Step 2 – Connect the plug-in transformer cables to the

terminals labeled “AC1” and AC2”.

Polarity is not observed in this connection.

Step 3 – Replace the lower panel cover, making sure that

the transformer cable is routed through the

provided opening at the bottom of the controller.
Step 4 – Plug the transformer into a 120 VAC, 60Hz

wall outlet.

Rain Sensor Installation (Optional)

IMPORTANT! The sensor circuit is designed for a NORMALLY-CLOSED rain sensor.

If a rain sensor is not connected, the sensor switch must be in the “OFF” position or the
jumper wire must be installed.

Step 1 – Remove the controller’s lower panel cover

to access the sensor terminals.
Step 2 – Route the rain sensor’s cable to the controller.
Step 3 – Remove the jumper cable from the “RS1” and

“RS2” terminals. Connect the sensor cables to

the terminals.
Step 4 – Replace the lower panel cover.
Step 5 – Place the “SENSOR” switch to “ON” to

Master Valve and Station Connection

Using 18-gauge (maximum 14-gauge wire can be used), multi-strand, direct burial
irrigation valve connection cable is recommended. Select a cable that provides at least one
wire for each valve and one extra wire for the common connection.

IMPORTANT! To prevent corrosion and possible short circuit, use waterproof wire

connectors on all splices.
Step 1 – To provide a valve common connection, splice one cable wire (generally the white

wire) and connect it to one solenoid lead from each of the valves.
Step 2 – Connect a separate wire to the remaining solenoid lead from each valve.
For reference, note the wire color code being used for each valve connection

and the associated watering station.
Step 3 – Remove the controller’s lower

panel cover to access the master valve

and station terminals.
Step 4 – Route the wire cable into the controller

through the opening at the base of the

unit.
Step 5 – Secure the designated valve common

wire to the “COM” terminal.
Step 6 – Secure the Master Valve to the “MV”

terminal and the stations to their

corresponding terminals (S1, S2, S3, ...).
Step 7 – Reinstall the lower panel cover.
