OptiFlex™ Advanced Equipment Controller – OF683XT-E2

The OptiFlex™ - OF683XT-E2 is a versatile and advanced equipment controller designed for small-scale building automation applications, such as controlling fan coil units, heat pumps, and managing zone-level systems. It is also ideal for integrating devices like Variable Frequency Drives (VFDs), electric meters, lighting systems, and Modbus-compatible occupancy sensors. This controller is fully compatible with the WEBCTRL® Building Automation System, enabling efficient management of a building’s environmental, energy, security, and safety systems—all from a single, unified platform.

The connectivity supports direct connection or daisy chain topology over BACnet/IP, and integrates with devices such as VFDs, electric meters, lighting systems, and Modbus occupancy sensors. It acts as a controller for the WebCONTROLLER in the WEBCTRL® Building Automation System, integrating environmental, energy, security, and safety systems. Supports EIKON® graphical programming software for custom control sequences and compatible with Automated Logic communicating ZS sensors and OptiPoint™ touchscreen interfaces. The Real-time Clock Capacitor-backed clock maintains time for up to 3 days during power failures and uses non-volatile memory to store control programs and historical data, with 4 GB eMMC Flash memory and 256 MB DDR3 DRAM. It archives user data to non-volatile flash memory every 90 seconds and is available for local device updates and service connections.

The main advantages are the reduction in energy consumption and the improvement of comfort through precise control of environmental conditions. Supports sustainable building operations by integrating various systems into one management tool and provides live visual displays of control logic aid in system optimization and troubleshooting.
