This document provides installation, troubleshooting, and operational instructions for the Hydrotek® 1000 and 2000 Series single station controllers, as well as the 2510, 2514, and 2520 Rainswitch Ready Controllers. These devices are designed to manage automated systems, primarily for irrigation, by controlling the timing and duration of operations.

Controller Functions

The core of the controller's functionality revolves around several key components:

• Time Dial: This dial completes one clockwise revolution every 24 hours. It is used to program automatic operations by inserting timing pins into its holes. To set the correct time of day, align the "TIME" arrow with the current time displayed on the dial. It's crucial to set the Time Dial only in the clockwise direction, never forcing it in reverse.

• Day Wheel and Retained Pin Assembly: This component features 14 pin locations, allowing for a two-week program. The controller will only operate automatically on days where the corresponding day wheel pin is fully depressed. To set the correct day, align the "DAY" arrow with the day indicated on the wheel. Pins should be pushed down for desired operation days and gently pulled out for days when operation is not desired.

• AUTO-OFF-ON Switch Knob: This knob allows users to select the desired function of the controller. Turning it to "ON" enables manual operation, "AUTO" activates automatic operation based on the programmed settings, and "OFF" stops both manual and automatic functions.

• Chassis Screws: These screws secure the controller chassis to its enclosure, ensuring the internal components are protected.

• Electrical Connection Strip (2000 Series): This strip facilitates the input and output electrical connections for the controller. Users should consult the Electrical Circuit and Connection Diagrams before proceeding with wiring.

Setting and Operation Instructions

To ensure proper functioning, follow these steps for setting up the controller:

• Setting Day of Week and Time of Day: First, rotate the Day Wheel until the correct day aligns with the "DAY" arrow. Next, turn the Time Dial CLOCKWISE until the current time aligns with the "TIME" arrow. Remember, the Time Dial must only be turned clockwise.

• Manual Operation: To operate the system manually, turn the Auto-Off-On switch to "ON." Once manual operation is no longer required, return the switch to "OFF."

• Daily Operation: The Day Wheel offers 14 days for programming. For each day you wish the controller to operate, fully depress the corresponding day wheel pin. For days when operation is not desired, gently pull the pins out.

• Setting Operating Times: The 24-hour Time Dial is divided into ninety-six 15-minute increments. Timing pins should be inserted into the Time Dial to specify the desired operating times. Each controller includes a package of white 15-minute pins. Longer operating periods can be achieved by placing multiple white pins consecutively. Shorter duration pins, such as yellow 7-minute pins and orange 4-minute pins, are also available.

• Operating a Multiple Zone Valve: For systems with multiple zone valves, operating times for each zone are represented by one or a group of pins on the Time Dial. Ensure there is at least one pin omitted between each zone's set of pins on the Time Dial to prevent overlap.

• Starting Automatic Operation: After setting the correct time and day, and programming the desired operating times, turn the Auto-Off-On switch knob to "Auto" to initiate automatic operation.

Electrical Connection Instructions

Important Safety Precaution: Always disconnect power to the controller prior to any installation or service work.

• For 1000 Series Controllers:

  1. Remove the controller face from the enclosure by unscrewing the two chassis screws.
  2. Make wire connections as indicated in the Electrical Circuit and Connection Diagram, securing them with the provided wire nuts.
  3. Reinstall the controller face into the enclosure.

• For 2000 Series Controllers:

  1. Remove the lower cover on the controller face.
  2. Make wire connections to the electrical connection strip as shown in the Electrical Circuit and Connection Diagram.
  3. Reinstall the lower cover on the controller face.

Cautions for Electrical Connections:

• Always ensure the correct controller model has been selected for the specific application.
• Use appropriate gauge wire and verify that all wiring complies with local electrical codes.
• Avoid pulling excessively on controller wires during connections, as this can lead to disconnections.
• Properly ground the controller to prevent electrical hazards.
• When reinstalling the controller face or lower cover, be careful not to trap any wires between the standoffs and screws.

Setting and Connection Instructions for 2200 Series Controllers:

• To operate a 2200 Series Controller continuously every 10 minutes, ensure all 14 CYCLE WHEEL pins are pushed in.
• When setting the TIME DIAL, always turn it in a CLOCKWISE direction. Never force it in reverse.

Troubleshooting

Important: Disconnect power before working on the power supply or load.

I. Problem: Controller fails to keep proper time.

• Cause: No power or improper voltage to motor.

  • Solution: Check the Electrical Circuit and Connection Diagram for proper power connection to the controller. Verify the voltage supply to ensure it matches the specified motor voltage (120 or 240 volts).

• Cause: Clock motor running but time dial not turning (possibly a broken drive gear).

  • Solution: Remove the time dial and inspect the drive gear. Install a new drive gear, ensuring the "this side out" orientation is correct. Reinstall the time dial and confirm it turns freely clockwise.

II. Problem: Controller improperly staying ON.

• Cause: Switch is being activated.

  • Solution: Ensure that wires do not press against the switch or relay.
  • Solution: Verify that wires leading to the switch are not pulled out.

• Cause: Controller improperly wired.

  • Solution: Check the Electrical Circuit and Connection Diagram to ensure that input wires are not wired directly to the load.

• Cause: Switch adjustment needed for proper automatic operation.

  • Solution: Make the necessary switch point adjustment as outlined in part IV of the Troubleshooting Guide.

• Cause: Switch knob not in OFF position.

  • Solution: Turn the Auto-Off-On switch to "OFF."

III. Problem: Controller does not turn ON in manual mode.

• Cause: No power to controller.
  • Solution: Ensure the controller is properly wired as per the Electrical Circuit and Connection Diagram.
  • Solution: Check the circuit breaker.

IV. Problem: Controller fails to operate properly in automatic (AUTO) mode.

• Cause: Daywheel not properly programmed.

  • Solution: Refer to the "Setting and Operation Instructions" for programming the day wheel.

• Cause: Auto-Off-On knob not set properly.

  • Solution: Turn the Auto-Off-On knob to the "Auto" position.

• Cause: Switch needs adjustment.

  • Solution: Disconnect power and remove the controller face. The switch adjustment screw is on the switch cover. A click should be heard when the switch arm is slowly pulled back halfway between the time dial's edge and the timing pin's far edge. Tighten the screw clockwise with a small screwdriver to activate the switch sooner. Turn counterclockwise slightly if the switch activates sooner than desired.

• Cause: Switch contacts or relay worn out.

  • Solution: Replace the switch or relay (refer to the parts list), ensuring the controller is properly rewired. A nut driver tool is available to assist in removing black retainer nuts.

If these troubleshooting tips do not resolve the issue, consult your local K-Rain distributor for service or replacement.
