The Automated Logic OptiFlex OF253A-E2 is a BACnet advanced application controller designed for zone-level temperature, air quality, and energy management. It features a built-in airflow sensor and patented flow control algorithm, making it suitable for applications requiring precise airflow management.
Factory pre-engineered control algorithms compliant with ASHRAE Guideline 36 are designed to reduce energy consumption and improve occupant comfort. EIKON graphical programming software allows custom control sequences, while a library of standard programs supports common unitary equipment and zone applications.
The OF253A-E2 integrates with the WebCTRL building automation system and supports Automated Logic ZS sensors, OptiPoint touchscreen interfaces, smart valves, and other compatible communicating devices. Dual Ethernet ports support BACnet/IP and BACnet/Ethernet communications, while onboard USB service access supports setup and troubleshooting.
This model is UL 864 10th Edition compliant and can be installed on DIN rail or by screw mounting in suitable equipment locations.
