Information About ZN341V
The ZN341V is part of Automated Logic’s ZN series of advanced VAV controllers engineered for variable air volume terminal units. It incorporates a brushless DC actuator and precision airflow measurement technology to maintain accurate control across minimum and maximum airflow setpoints. The controller supports BACnet communication via ARCNET 156 Kbps or MS/TP networks, allowing peer-to-peer data exchange with other building controllers. With onboard memory, graphical programmability, and compatibility with RS room sensors, it is suited for cooling-only, reheat, constant volume, and dual-duct HVAC configurations.
Key Features:
- Pressure-Independent VAV Control: Maintains accurate airflow regardless of duct pressure fluctuations.
- Integrated Brushless Actuator: 35 in-lb torque motor designed for long operational life and consistent damper positioning.
- Native BACnet Communication: Supports BACnet over ARCNET (156 Kbps) or MS/TP for system-wide integration.
- Precision Airflow Sensor: Built-in airflow measurement ensures accurate CFM control and efficient balancing.
- Flexible I/O Configuration: Includes universal inputs, digital outputs, and a 0–10 VDC analog output for reheat or valve control.
- Graphical Programming Capability: Fully programmable with downloadable firmware and diagnostic trending support.
- RS Sensor and Rnet Support: Enables local access, monitoring, and simplified test-and-balance procedures.
- Compact Plenum-Rated Enclosure: UL94-5VA rated housing suitable for installation in air-handling spaces.
The ZN341V delivers the reliability and precision required for advanced VAV terminal unit control in commercial HVAC systems.
