The Automated Logic OptiFlex OF141-E2 is an advanced VAV controller designed for zone-level temperature and air quality control. It is suitable for Variable Air Volume (VAV) and Variable Volume and Temperature (VVT) applications, providing flexible control for a variety of building automation environments.
Factory pre-engineered control algorithms compliant with ASHRAE Guideline 36 are designed to reduce energy consumption and improve occupant comfort. EIKON graphical programming software supports custom control sequences, while a library of standard programs supports common unitary equipment and zone applications.
The OF141-E2 features an integral precision differential pressure sensor for airflow measurement and supports BACnet/IP and BACnet/Ethernet communications through dual Ethernet ports. It integrates with the WebCTRL building automation system and supports compatible ZS sensors, OptiPoint touchscreen interfaces, smart valves, and other communicating devices.
A bright LED locator light helps technicians identify the controller's location and damper rotation direction. The controller also supports remote firmware upgrades, USB service access, and DIN rail or screw mounting.
