High‑capacity, scalable controller for complex HVAC and zone applications
The OptiFlex™ Advanced Equipment Controller OF683T‑E2 delivers expanded integration capacity and flexible control for advanced HVAC and zone applications, supporting graphical programming, open‑protocol communications, and robust hardware design.
The OptiFlex advanced equipment controller, model OF683T-E2, is ideal for small equipment control applications such as fan coil units, heat pumps, and advanced zone control applications requiring direct connection or daisy chain topology over BACnet/IP and integration of devices such as VFDs, electric meters, lighting systems and Modbus occupancy sensors.
The controller includes dual Ethernet ports supporting BACnet/IP daisy‑chain configurations with Spanning Tree Protocol (STP) for enhanced network stability.
The controller supports integration of up to 80 Modbus points, enabling communication with a wide range of third‑party devices.
Control programs and historical data are stored in non‑volatile memory, eliminating battery replacement and data loss concerns.
The controller supports DIN rail or screw mounting and is suitable for installation in mechanical rooms, equipment boxes, or other weather‑protected locations.
The OF683T‑E2 provides higher Modbus integration capacity, making it suitable for more complex systems with extensive third‑party device integration.
It is designed for advanced HVAC and zone applications such as chilled beams, unit ventilators, exhaust fans, and air curtains.
No. The controller uses non‑volatile memory and a capacitor‑backed real‑time clock, eliminating the need for batteries.
Yes. Flexible mounting options, open‑protocol communications, and scalable integration make it suitable for both new installations and retrofit applications.
