Intermatic ET2745C Control
The Intermatic ET2745C is a professional-grade 7-day 4-circuit electronic control designed for precise load management in commercial and industrial HVACR environments. This multi-circuit time switch features automatic voltage detection (120-277 VAC), allowing for seamless integration without manual DIP switch adjustments. With 96 available set points and 50 holiday blocks, it provides the granularity required for complex scheduling, such as staged equipment starts or synchronized lighting and pump cycles. The dry contact SPST relays are built with zero-crossing technology, significantly reducing inrush current wear on internal components and extending the life of the control. A high-performance 100-hour supercapacitor maintains your programming during power interruptions, eliminating the maintenance overhead of replacing batteries. Housed in a rugged NEMA 1 indoor metal enclosure, the ET2745C offers non-volatile EEPROM memory for permanent schedule retention, ensuring reliable automation for multi-load systems and machinery controls.
Key Benefits for Contractors:
- Multi-Circuit Flexibility: Independently control up to four circuits or configure outputs for DPST or pulse applications.
- Maintenance-Free Backup: The supercapacitor power backup keeps the clock running for 100 hours without a battery.
- Universal Voltage Input: Features 120-277 VAC automatic switching for reduced inventory and faster field installation.
- USB Port Integration: Simplifies multi-site deployment by allowing schedule transfers via USB.
- Zero-Cross Technology: Protects relay contacts from high-inrush LED lighting and motor loads.
Common Questions & Technical Insights:
Can I use this for both lighting and motor loads simultaneously?
Yes. Each of the four circuits can be programmed independently, making it suitable for mixed applications such as indoor lighting control and machinery/pump scheduling on separate channels.
How do I handle federal holidays or plant shutdowns?
The controller supports up to 50 holiday blocks. You can program specific dates in advance to override the 7-day schedule, preventing energy waste during scheduled closures.
Is this unit compatible with high-efficiency LED drivers?
Absolutely. The relays incorporate zero-crossing technology, which triggers the switch at the zero-voltage point of the AC cycle, specifically designed to handle the high inrush currents typical of electronic ballasts and LED drivers.
