Key Features and Benefits

• Optimized design for all types of pressure independent VAV applications including cooling only, cooling with modulated hot water re-heat, cooling with electric re-heat, constant volume boxes and dual duct boxes.
• Uses a high speed 16-bit microprocessor with 1 MByte Flash memory and 512 KByte of RAM for graphical programming, diagnostic trends, and easy firmware upgrades using remote downloading - no chip replacement necessary.
• Built-in 0-10 Vdc AO for baseboard or re-heat valve actuator.
• Compact and rugged design for easy mounting and an integral brushless actuator for reliability and longevity.
• The combination of the precision air flow sensor and advanced VAV algorithm assures occupant comfort both at minimum and maximum design air flows, while maximizing actuator life.
• Compatible with the ZASF integral air flow sensor/ actuator assembly for dual duct applications.
• Rnet port supports Automated Logic’s line of RS room sensors and provides local access to the system.
• The ZN341v+/ZN141v+ controllers are fully graphically programmable and offer full peer-to-peer communications with other ZN line, ME line, or SE line controllers. Graphical programs are universally understood and provide self-documenting control sequences.
• Easy-to-use test and balance program via RS sensor or Rnet connection.

The ZN141v+ control module is used for zone control. It has a built-in flow sensor and actuator, uses a patented flow control algorithm, and mounts directly on the VAV box damper shaft. Exec. B ZN module with integrated actuator and flow sensor.

Automated Logic’s ZN341v+/ZN141v+ are designed for a variety of pressure-independent VAV applications. These advanced controllers feature an integral actuator, advanced precision air-flow sensor, flexible connectivity to the full line of RS sensors, and easy-to-use air balance routines. Sophisticated pre-engineered control algorithms reduce energy consumption, maximize actuator life, and ensure occupant comfort. The ZN series controllers are fully programmable and provide networked peer-to-peer communications using native BACnet-over-ARCNET 156 kbps or MS/TP.
