Key Features and Benefits

• Powerful zone controller for VAV, heat pump, unit ventilator and other packaged HVAC applications.
• Native BACnet communications to field devices over a high speed ARCNET 156 kbps or BACnet MS/TP network.
• Uses a high speed 16-bit microprocessor with 1 MByte Flash memory and 512 KByte of RAM for unparalleled programmability. Firmware upgrades can be downloaded remotely - no chip replacement necessary.
• The ZN551 is part of a full line of ZN controllers which include a variety of Universal Inputs, Binary Outputs and 0-10VDC Analog Outputs. Other ZN models with built-in flow sensors and/or integral damper actuators are available as well as optional single/dual air flow sensors for pressure independent VAV applications.
• Rnet port supports Automated Logic's line of RS room sensors and provides local access to the system.
• The ZN551 controller is fully graphically programmable and offers 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.
• An extensive library of pre-engineered control routines provides proven solutions for most zone control applications. Custom programs can be easily written in EIKON, ALC's legendary graphic programming language.
• Compact and rugged plastic enclosure for easy mounting.

Automated Logic's ZN551 provides unprecedented power and flexibility through fully programmable networked controllers. The ZN551 controllers connect to the Building Automation System (BAS) network using BACnet over ARCNET 156 kbps or MS/TP. The ZN551 supports a line of RS room sensors using Rnet port.
