High‑performance controller for flexible, advanced HVAC and zone applications
The OptiFlex™ Advanced Equipment Controller OF683XT‑E2 delivers robust, scalable control for complex HVAC and zone applications, combining graphical programming, open‑protocol integration, and reliable, battery‑free hardware design.
The OptiFlex advanced equipment controller, model OF683XT-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 reliable network operation.
The controller supports integration of up to 50 Modbus points, enabling communication with third‑party equipment and systems.
Control programs and historical data are stored in non‑volatile memory, eliminating battery replacement and preventing data loss.
The controller supports DIN rail or screw mounting and is suitable for installation in mechanical rooms, equipment boxes, or other weather‑protected locations.
It is designed for advanced HVAC and zone applications such as chilled beams, unit ventilators, exhaust fans, and air curtains.
The OF683XT‑E2 offers expanded Ethernet‑based networking with Modbus integration, making it suitable for systems requiring flexible, open‑protocol connectivity.
No. The controller uses non‑volatile memory and a capacitor‑backed real‑time clock, eliminating battery replacement.
Yes. EIKON® graphical programming allows full customization of control logic.
