High‑capacity controller for advanced HVAC and zone control applications
The OptiFlex™ Advanced Application Controller OF683‑E2 delivers flexible, scalable control for a wide range of HVAC and zone applications, combining graphical programming, robust BACnet/IP networking, and seamless WebCTRL® integration.
The OptiFlex advanced application controller, model OF683-E2, is ideal for advanced zone control applications requiring direct connection or daisy chain topology over BACnet/IP. Factory, preengineered ASHRAE Guideline 36 compliant control algorithms reduce energy consumption and increase occupant comfort.
The controller includes dual Ethernet ports supporting native BACnet/IP, daisy‑chain networking, and Spanning Tree Protocol (STP) for reliable and resilient network operation.
Supports both hard‑wired and wireless service connections, enabling flexible commissioning and troubleshooting.
Uses non‑volatile memory to store control programs and historical data, eliminating the need for batteries.
A capacitor‑backed real‑time clock maintains accurate timekeeping for at least three days during power failures.
It is designed for advanced HVAC and zone control applications, including chilled beams, unit ventilators, exhaust fans, and air curtains.
The controller supports BACnet/IP with dual Ethernet ports, daisy‑chain configurations, and STP for network resiliency.
No. Programs and data are stored in non‑volatile memory, and timekeeping is handled by a capacitor‑backed clock.
Yes. Its scalable design, flexible networking, and service‑friendly features make it suitable for both new installations and retrofit applications.
