The Automated Logic OptiFlex OF342-E2 is an advanced variable air volume (VAV) controller designed for zone-level temperature, air quality, and energy management. It is suitable for VAV and variable volume and temperature (VVT) applications and integrates with the WebCTRL building automation system.
The controller features factory pre-engineered control algorithms compliant with ASHRAE Guideline 36, 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 OF342-E2 includes an integral precision differential pressure sensor for airflow measurement and a damper-mounted actuator. Dual Ethernet ports support BACnet/IP and BACnet/Ethernet communications, including daisy-chain networking with Spanning Tree Protocol. The controller also supports Automated Logic ZS sensors, OptiPoint interfaces, smart valves, and other compatible communicating devices.
This model is UL 864 10th Edition compliant and includes a bright LED locator light that helps identify the controller's location and indicate damper rotation direction.
