The Irritrol RD-600 controllers are designed for compatibility with a wide range of 24VAC irrigation valves. This includes both Irritrol valves and those manufactured by other leading brands. Ensuring proper valve compatibility is crucial for reliable operation and preventing damage to the controller or valves.
Consider valve inrush current requirements; the RD-600 has a maximum valve capacity. Using valves exceeding this capacity can lead to controller malfunction. Always verify valve specifications before installation to guarantee seamless integration.
Wiring Specifications
Irritrol RD-600 controllers utilize low-voltage wiring, typically 18-22 gauge solid core wire, for connecting valves and sensors. Proper wiring is essential for reliable operation. Ensure all connections are secure and weatherproof to prevent corrosion and signal interference.
The controller requires a dedicated 24VAC transformer. Follow the wiring diagrams carefully, paying attention to common and valve wire connections. Incorrect wiring can damage the controller or valves, voiding the warranty.
Installation Guide for RD-600
Proper RD-600 installation involves secure mounting, correct valve and sensor wiring, and careful initial programming for optimal performance and long-term reliability.
Mounting the Controller
Securely mount the RD-600 indoors, protecting it from direct sunlight and weather exposure. Choose a location near a grounded electrical outlet and within range of the irrigation valves. Ensure sufficient space around the controller for wiring and future servicing. Utilize appropriate mounting hardware, firmly attaching it to a solid surface like a wall or inside an enclosure. Avoid mounting near sources of electromagnetic interference, which could disrupt operation. Proper mounting safeguards the controller and ensures reliable performance throughout the irrigation season.
Wiring the Valves and Sensors
Connect valve wires to the designated terminals on the RD-600 controller, referencing the wiring diagram. Employ appropriate wire connectors for secure and weatherproof connections. Similarly, connect rain sensors or flow sensors to their respective terminals. Ensure correct polarity when wiring sensors. Double-check all connections before powering on the controller, verifying wire gauge compatibility and proper insulation. Incorrect wiring can damage the controller or sensors, leading to system malfunctions and inefficient water usage.
Initial Setup and Programming
After wiring, power on the RD-600 controller. The initial setup involves setting the date and time accurately, crucial for schedule functionality. Program watering schedules based on plant needs and local weather conditions. Begin with simple schedules, gradually adding complexity as needed. Test each zone individually to confirm proper valve operation and spray pattern coverage. Regularly review and adjust schedules based on seasonal changes and rainfall to optimize water conservation.

Programming the RD-600 Controller
RD-600 programming allows customized watering schedules, setting date/time, and utilizing advanced options for efficient irrigation management, optimizing water use and landscape health.
Setting the Date and Time
Accurate date and time settings are fundamental for proper RD-600 operation. Begin by accessing the programming mode, typically via the “Program” or “Set” button. Navigate to the date setting, using the up/down arrows to adjust the month, day, and year. Confirm each selection.
Next, set the time, adjusting hours and minutes similarly. Ensure AM/PM is correctly configured. Saving these settings is crucial; consult the manual for specific button sequences. Incorrect time impacts schedule execution, leading to over or under-watering.
Creating Watering Schedules
Establishing watering schedules on the RD-600 involves defining start times, durations, and days of the week for each zone. Access the programming mode and select “Schedule.” Assign a number to each zone, then input the desired start time using the arrow buttons. Set the watering duration in minutes – consider plant type and weather.
Choose watering days; options include individual days or pre-set cycles. Save each schedule individually. Review all programmed schedules to confirm accuracy before exiting programming mode, ensuring efficient water usage.
Advanced Programming Options
The RD-600 offers advanced features like seasonal adjustment, allowing proportional reduction or increase of watering times based on changing weather. Program “Smart Cycle” to break long run times into shorter cycles, preventing runoff. Utilize the manual run function for immediate zone activation, useful for testing or supplemental watering.

Troubleshooting Common Issues
Addressing problems with your RD-600 is often straightforward. Common issues include power failures, valve malfunctions, and sensor errors – easily diagnosed with systematic checks.
No Power to the Controller
If the RD-600 lacks power, begin by verifying the main power supply. Check the circuit breaker or fuse responsible for the controller’s zone. Ensure the transformer is securely connected and functioning correctly; a multimeter can test its output voltage. Inspect all wiring connections for looseness or corrosion, particularly at the power input terminals.
Confirm the controller’s battery is adequately charged, as a depleted battery can prevent operation even with AC power present. Finally, examine the power cord for any visible damage or breaks.
Valves Not Activating
When valves fail to activate with the RD-600, first confirm the program is correctly scheduled and active. Verify the valve wiring is secure and matches the programmed zone assignments. Use a multimeter to test valve solenoid continuity; a broken solenoid requires replacement. Check for obstructions within the valve itself, like debris or a faulty diaphragm.
Insufficient power to the valve or a tripped solenoid can also cause this issue; inspect wiring for breaks.
Sensor Malfunctions
If sensors aren’t functioning with your RD-600, ensure proper wiring connections and sensor placement according to the manual. Verify the sensor type is correctly configured within the controller’s programming. A faulty sensor may require replacement; test its output signal with a multimeter to confirm functionality.
Check for obstructions or damage to the sensor itself, impacting its readings. Confirm sensor compatibility with the RD-600.

Maintenance and Care
Regular cleaning and upkeep are crucial for optimal RD-600 performance. Replace batteries annually and winterize the system to prevent damage from freezing temperatures.
Cleaning the Controller
To ensure longevity, periodically clean the RD-600 controller’s exterior. Disconnect power before cleaning! Use a damp cloth – avoid harsh chemicals or abrasive cleaners, as these can damage the unit’s casing and electronic components. Gently wipe down the controller’s surface, removing any dust, dirt, or debris. Pay close attention to the display screen and button areas. Ensure the enclosure is completely dry before restoring power. Regular cleaning prevents corrosion and maintains a professional appearance, contributing to reliable operation.
Battery Replacement
The RD-600 utilizes a battery to retain programming during power outages. Replace the battery annually, or when the low battery indicator appears on the display. Access the battery compartment – typically located inside the controller’s case – and carefully remove the old battery. Install a new, compatible battery, ensuring correct polarity (+/-). Proper battery maintenance safeguards your irrigation schedules, preventing data loss and ensuring uninterrupted operation. Always use the specified battery type for optimal performance and longevity.
Winterization Procedures
Protect your RD-600 from freezing temperatures to prevent damage. First, turn off the water supply to the irrigation system. Then, manually operate each valve to release remaining water from the lines, preventing pipe bursts. Disconnect the valve wires from the controller. Finally, remove the controller’s battery to avoid corrosion. Store the controller in a dry, sheltered location until spring. Proper winterization ensures a trouble-free start to the next irrigation season.
