The image displays the main dial for percentage ON time selection, the 'Select Cycle Time' button, and a row of LEDs indicating the chosen cycle duration (30s, 60s, 180s, 5m, 10m, 30m, 1h, 4h). Instructions for programming the cycle timer are printed on the lower part of the device's label.

3. Setup and Installation

Installation of the Intermatic CT2000 involves electrical wiring. It is recommended that installation be performed by a qualified electrician in accordance with all local and national electrical codes. Ensure power is disconnected at the circuit breaker before beginning any wiring.

General Installation Notes:

• The device is designed for surface mounting.
• Connect the timer to a 120/240 VAC, 60 Hz power source.
• Ensure proper grounding as per electrical safety standards.
• Refer to the wiring diagram provided inside the unit's enclosure for specific connection details.

4. Operating Instructions

The CT2000 allows you to set a specific cycle duration and then determine what percentage of that cycle the connected load will be ON.

Programming the Cycle Timer:

1. Select Total Cycle Time: Turn the central knob until the "Select Cycle Time" arrow on the dial aligns with the triangle indicator. This action selects the total duration for one complete cycle (e.g., 30 seconds, 1 hour, 4 hours).
2. Scroll Through Cycle Times: Push the 'Select Cycle Time' button to scroll through the available cycle durations. The corresponding LED above the dial will illuminate to indicate the currently selected cycle time.
3. Save Desired Cycle Time: Once the desired cycle time is displayed by the LED, push and hold the 'Select Cycle Time' button until the LED blinks. This action saves the selected cycle duration.
4. Set Percentage ON Time: Turn the central knob again until the desired percentage of the cycle time (e.g., 10%, 50%, 90%) aligns with the triangle indicator. This sets how long the load will be active within the chosen total cycle duration.

The timer will now operate according to your programmed settings. The 'OFF' and 'ON' indicators will show the current status of the output.

5. Maintenance

The Intermatic CT2000 Percentage Cycle Time Switch is designed for minimal maintenance. Regular inspection is recommended to ensure optimal performance.

Maintenance Guidelines:

• Cleaning: Periodically wipe the exterior of the unit with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Inspection: Annually inspect the wiring connections for tightness and signs of wear or corrosion. Ensure the enclosure remains sealed and free from damage.
• Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent damage. The NEMA 3R enclosure provides protection against rain, sleet, and external ice formation.

Always disconnect power before performing any maintenance or inspection.

6. Troubleshooting

If the Intermatic CT2000 is not functioning as expected, consider the following troubleshooting steps:

Common Issues and Solutions:

• No Power: Check the circuit breaker to ensure power is supplied to the unit. Verify all wiring connections are secure.
• Load Not Activating: Confirm that the percentage ON time is set correctly and that the cycle duration is active. Check the connected load for functionality.
• Incorrect Timing: Re-program the cycle time and percentage ON time following the operating instructions carefully. Ensure the LED blinks to confirm saving of the cycle duration.
• Unit Not Responding: If the unit is completely unresponsive, disconnect power for a few minutes and then restore it. If the issue persists, professional assistance may be required.

For persistent issues or complex problems, contact Intermatic customer support or a qualified electrician.
