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.

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 monitor the sensor status

Master Valve and Station Connection

• 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.
