Intermatic CT2000 Cycle Timer

The Intermatic CT2000 Cycle Timer is the heavy-duty, field-adjustable percentage cycle time switch designed for precision in demanding agricultural and industrial environments. Serving as the direct high-performance replacement for the discontinued Intermatic C8865, this unit provides repetitive cycling for critical equipment such as livestock feeders, greenhouse misters, and ventilation fans. Built with a rugged NEMA 3R aluminum enclosure, it is engineered to withstand harsh ammonia and wash-down environments while offering 6000V surge protection for internal circuitry.

This 20 Amp cycle timer features an intuitive interface with 8 field-selectable durations ranging from 30 seconds to 4 hours. Contractors can fine-tune operations using 30 separate detent positions for exact percentage-on control. The SPST switch supports dual-voltage 120/240 VAC applications, and the isolated relay contacts allow the load to operate on a different circuit than the clock power. With non-volatile memory, your repetitive cycle timer settings remain secure during power interruptions, eliminating the need for battery backups or complex DIP switch configurations.

• Direct Replacement: Seamlessly replaces the legacy Intermatic C8865 model with modern digital reliability.
• Versatile Voltage: Compatible with 120/240 VAC systems, rated for up to 2 HP motor loads.
• Environmental Protection: The NEMA 3R housing protects against dust and moisture in outdoor or industrial settings.
• Precise Control: 8 selectable total cycle times with adjustable percentage-on durations from 3% to 97%.
• Manual Override: Includes a front-facing button for temporary or permanent manual ON/OFF control without affecting saved programmed cycles.

• How do I handle wiring for a 240V load? The unit is shipped in the 240V position by default. Ensure the internal SW1 selector matches your clock power, and use the isolated red leads for your load connections to prevent backfeeding the control board.
• Can I use this for fogging systems? Yes, the Intermatic CT2000 is ideal for short-cycle applications like foggers and misters where specific "on" intervals are required within a set time block.
• What happens if the power goes out? The non-volatile memory ensures all timing parameters are preserved, so the unit resumes its percentage timing sequence immediately upon power restoration.
