Flexible, high‑performance controller for advanced zone‑level HVAC applications
The OptiFlex™ Advanced Application Controller OF253A‑E2 provides reliable, distributed control for zone‑level temperature, indoor air quality, and energy management applications, combining graphical programming, robust BACnet/IP networking, and seamless WebCTRL® integration.
The OptiFlex advanced application controller, model OF253A-E2, is a central component of the WebCTRL system. These controllers are ideal for zone-level temperature and air quality control applications, and feature a built-in flow sensor with a patented flow control algorithm. Factory, pre-engineered ASHRAE Guideline 36 compliant control algorithms reduce energy consumption and increase occupant comfort. Designed to operate in a wide range of environmental conditions, this controller is well suited for equipment boxes, or almost any other weather-tight location.
The controller includes dual high‑speed Ethernet ports supporting native BACnet/IP, daisy‑chain networking, and Spanning Tree Protocol (STP) for reliable and resilient 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 at least three days during power failures or network interruptions.
It is designed for zone‑level HVAC applications, including temperature control, indoor air quality management, and energy optimization.
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.
Yes. Its compact design, flexible networking, and service‑friendly features make it suitable for both new installations and retrofit applications.
