Setting the Controller

Setting to Off

Turn the dial to “OFF”. No watering occurs. The display shows “OFF,” time, and day.

Setting to Run Automatically

Turn the dial to “AUTO”. The controller runs in automatic mode, adhering to programmed schedules.

Program Select Button

Use the PROGRAM select button to choose program A, B, or C. The selected program appears on the display. Programming applies only to the selected program. Program C is for lighting if the lighting feature is used.

Rain Sensor Select Button

This button allows bypassing the rain sensor. If bypassed, “BYPASSED” appears on the LCD. A rain sensor or wire jumper must be installed when the button is ON to run a program.

Programming

The Pro-LC offers three independent programs (A, B, C) for different watering needs. Programs can stack if they overlap. Each program requires at least one start time, watering day(s), and one station run time. Up to four start times per program are available for efficient watering.

Set Time / Date

Turn the dial to SET TIME/DATE. Use DOWN/UP buttons to set hours, minutes, day, month, and year. Press NEXT to advance between fields. The display can toggle between 12 or 24-hour format by pressing BACK and NEXT simultaneously.

Set Program Start Times

Up to four start times can be set per program. Select program (A, B, C), turn dial to SET PROGRAM START TIMES, and use DOWN/UP buttons to set time in 15-minute increments. Set to “OFF” to eliminate a start time. Press NEXT for additional start times.

Set Watering Days

Choose from three watering cycles:

• CUSTOM: Waters on selected days of the week.
• ODD: Waters on odd-numbered days of the month.
• EVEN: Waters on even-numbered days of the month.

To set CUSTOM days, turn dial to SET WATERING DAYS. Use DOWN/UP to enable (ON) or disable (OFF) each day. Press NEXT to advance to the next day.

Set Cyclic Water Cycle

This feature allows setting a watering cycle based on days remaining and a day cycle. Turn dial to Set Watering Days, press BACK and NEXT simultaneously until “CYCLE” appears. Set “DAYS REMAINING” and “DAY CYCLE” (1-31 days) using DOWN/UP buttons.

Set Station Run Times

Stations 1-12 can run from 1 minute to 6 hours. Set run times for each station in the selected program (A, B, C) by turning the dial to SET STATION RUN TIMES. Use DOWN/UP buttons for minutes/hours. Set to “OFF” if no run time is needed. Press NEXT to advance to the next station.

Manual Program Operation

Manually start any program (A, B, C) by selecting the program, turning the dial to AUTO, and pressing MANUAL START/NEXT. The display shows “RUN” and the current station’s remaining time. Manual operation can be canceled by turning the dial to OFF for 3 seconds.

Running a Single Station Manually

To run a single station, select the program (A, B, C), turn the dial to RUN SINGLE STATION, press NEXT, select the station using UP/DOWN, and press MANUAL START. Previously programmed run times can be adjusted during manual operation, but these changes do not affect the stored program run times.

Valve Locator

Helps find buried valves by pulsing their solenoids. Turn the dial to RUN SINGLE STATION/SYSTEM TEST, press UP/DOWN until “LOCATE” appears, then press MANUAL START to begin. Press MANUAL START again to advance to the next available station.

Test All Stations

Run a test program to check all stations. Turn the dial to SYSTEM TEST, press UP/DOWN until “TEST” appears, then press MANUAL START. The display shows “RUN” and remaining time for the first station. Test run time can be altered using UP/DOWN. Press NEXT to advance to the next station.

Installation

The Pro-LC controller can be installed indoors or outdoors, complying with local electrical codes. Installation at eye level is recommended for best viewing and ease of programming. Ensure the mounting location has access to 115VAC or 220VAC power and sufficient clearance for conduit or junction boxes.

CAUTION: Ensure installation is performed by a qualified professional. Wiring terminals must be protected by insulating materials.

This appliance is not intended for use by persons with reduced physical, sensory, or mental capabilities, or lack of experience, unless supervised. Children should be supervised not to play with the appliance.

Door Removal

1. Open the enclosure door and swing it left.
2. Grasp top and bottom of the door at the hinge with both hands.
3. Gently pull forward until the door releases.

Mounting the Controller

The controller has a keyhole slot on top/back and two mounting holes at the bottom/back. Mark the desired mounting position at eye level. Drive a fastener into the mark for the keyhole and hang the controller. Ensure the controller is level by using the lower circular mounting holes.

Field Wire Entrances

Two plugs are available at the bottom of the cabinet for routing valve, pump start, and sensor wires. These are sized for 1/2" PVC male adapters.

Connecting Valve Wires

Connect each valve's power wire to a numbered screw terminal (1-12). Connect the common field wire from all valves to the terminal screw between the Sensor and "P" (Pump) terminals. Use only code-approved wiring for underground installation.

Pump Start Relay

For systems requiring a pump start relay, the terminal is located between "C" and "1" screw terminals. The controller does not provide main power for a pump. Use jumpers for unused stations to prevent pump or system damage.

Rain Sensor Installation

Connect the two rain sensor wires to the terminals marked SENSOR, typically at #3 and #4 screw terminals. If using a rain sensor, uninstall the jumper wire. If not using a rain sensor, keep the jumper wire installed.

Powering the Controller

Recommendation: A licensed electrician should perform power installation. Ensure all electrical power is off before wiring. The enclosure door can be removed for easier installation.

Outdoor Controller: Use the bottom left hole for AC power wires and conduit. Connect AC wires to transformer wires inside the junction box, ensuring terminals are protected.

Indoor Controller: Powered by 24VAC with an external AC adapter. Simply plug the controller connector into the adapter.

Battery Replacement

The battery compartment is on the main board. The replaceable battery is a CR2032. CAUTION: Risk of explosion if replaced with an incorrect type. Dispose of used batteries properly.

Troubleshooting

Program Does Not Come On Automatically

• Cause: Dial set to OFF. Correction: Set dial to AUTO.
• Cause: No Start Time. Correction: Check program start times via PROGRAM DISPLAY or SET PROGRAM START TIMES.
• Cause: Permanent Day Off is Active. Correction: Change permanent day programming.
• Cause: Not a Scheduled Watering Day. Correction: Check program watering days via PROGRAM DISPLAY or SET WATERING DAYS.
• Cause: Active or Faulty Rain Sensor. Correction: Check display for BYPASSED/SENSOR. Set Rain Sensor Switch to BYPASSED. If watering doesn't resume, the sensor may be faulty.
• Cause: No Primary AC Power. Correction: Restore primary AC power.

Display Shows Station in Operation But No Watering Occurs

• Cause: Rain Sensor is Active. Correction: If due to recent rain, no action is needed. Place Rain Sensor Switch to BYPASSED to resume. If watering doesn't resume, the sensor may be faulty.
• Cause: Sensor Jumper is missing. Correction: Replace jumper.
• Cause: No Station Run Time set. Correction: Set run time via SET STATION RUN TIMES.

Station(s) Does Not Come On

• Cause: SHORT or OPEN circuit. Correction: Locate and repair circuit. Controller may flash error indicators. Temporarily turn dial to OFF then AUTO to clear alarm. Controller auto-resets after repair.

Display is Partially or Completely Blank

• Cause: Loss of primary AC power. Correction: Check electrical installation and breakers/fuses.
• Cause: Electrical surge/strike damaged electronics. Correction: Perform a controller RESET.

Station(s) Repeat Operation

• Cause: More than one start time programmed or programs stacked. Correction: Check all programs (A, B, C) and start times. Remove unwanted start times.

Override Message on Display

• Cause: Controller set to OFF via K-Rain App or rain threshold met. Correction: Turn dial to OFF for 2 seconds, then back to AUTO.

Lost WiFi Connection

• Cause: Router changed, password changed, dongle removed, or power outage. Correction: Reinstall BRIDGE WiFi dongle. Press and hold button for 5 seconds to reestablish connection.
