Advanced zone‑level VAV control with robust networking and service‑friendly design
The OptiFlex™ Advanced VAV Controller OF141‑E2 delivers flexible, high‑performance control for zone‑level temperature, indoor air quality, and energy management applications, combining graphical programming, BACnet/IP networking, and seamless WebCTRL® integration.
The OptiFlex advanced VAV controller, model OF141-E2, is a central component of the WebCTRL system. These controllers are ideal for zone-level temperature and air quality control applications. Designed to operate in a wide range of environmental conditions, these controllers are well suited to satisfy the market demands of Variable Air Volume ( VAV ) and Variable Volume and Temperature ( VVT ) applications. Factory, pre-engineered ASHRAE Guideline 36 compliant control algorithms reduce energy consumption and increase occupant comfort.
The controller includes dual high‑speed Ethernet ports supporting native BACnet/IP, daisy‑chain networking, and Spanning Tree Protocol (STP) for reliable network operation.
Supports both hard‑wired and wireless service connections, enabling flexible commissioning and troubleshooting.
Uses non‑volatile memory to store control programs and historical data, eliminating the need for batteries.
A capacitor‑backed real‑time clock maintains accurate timekeeping for up to three days during power failures or network interruptions.
It is designed for zone‑level VAV applications, including temperature control, air quality management, and energy optimization.
The LED helps quickly identify the controller’s location and damper rotation direction without requiring direct access to the air stream or electrical panel.
The controller supports BACnet/IP with dual Ethernet ports, daisy‑chain configurations, and STP for network resiliency.
No. Programs and data are stored in non‑volatile memory, and timekeeping is handled by a capacitor‑backed clock.
