Automated Logic continues to expand the OptiFlex line of digital building controllers, giving facilities increased flexibility in control options and configurations. The new OptiFlex VAV controllers, models OF342 and OF141, are ideal for zone-level temperature and air quality control applications. Designed to operate in a wide range of environmental conditions, the new controllers are ASHRAE Guideline 36 compliant with inherent algorithms that help reduce energy consumption and increase occupant comfort.

To help maximize energy efficiency and performance, ASHRAE Guideline 36 – High-Performance Sequences of Operation for HVAC Systems includes uniform sequences of operation for HVAC systems, which help provide control stability and allow for real-time fault detection and diagnostics.

OptiFlex - A Bridge to the Future

The OF342 and OF141 can be used on new projects and are also backwards compatible with legacy Automated Logic systems and its WebCTRL® building automation system, making retrofits quick and easy.

Designed to also support BACnet over IP, multiple IP network topologies can be used, including Daisy Chain, Ring, Home Run and Hybrid.

Engineering Observations

  • Take advantage of faster processing and high speed communication through BACnet over IP
  • A significant increase in controller RAM supports advanced analytics and fault detection & diagnostics algorithms
  • Supports new Automated Logic ACTnet valve bus, network up to 5 valve or damper actuators
  • The OF342 offers strong mix of inputs and outputs to meet the most demanding VAV application
  • Continued combo sensor support to meet ASHRAE Guideline 36 requirements
  • Easier and faster initial configuration via Bluetooth

The OptiFlex advanced VAV controllers, model OF342-E2 and OF141-E2, are a central component of the WebCTRL system and are well suited to satisfy the market demands of Variable Air Volume (VAV) and Variable Volume and Temperature (VVT) applications.
