Product Description
. . . . . The ZN551 is a fully programmable, native BACnet Advanced Application Controller (AAC) designed for controlling a single zone in a building. The ZN551 is well suited for VAV, heat pump, unit ventilator and other packaged HVAC applications. It communicates on an EIA-485 LAN using BACnet MS/TP or BACnet over ARCNET communications and connects seamlessly to the WebCTRL building automation system. Versatile controller suitable for a variety of applications, including fan coil units, lighting, and exhaust fan control. Standard library of control programs available for most zoning applications. Supports EIKON graphical programming software, an objectoriented tool that provides complete flexibility for any custom. control sequence that you need. Supports Automated Logic communicating sensors, which are available in a variety of zone sensing combinations and support setpoint adjustment and occupancy overrides. Supports Automated Logic touchscreen interfaces for managing and troubleshooting the connected equipment easily. Supports live, visual displays of control logic, which uses real time operational data and aids in optimizing and troubleshooting system operations. Quick & easy test and balancing process. HARDWARE FEATURES: Controls up to 11 points (5 binary outputs , 5 universal inputs and 1 analog output). High-speed, native BACnet over ARC156 communications delivers high speed response when you need it. Supports native BACnet over MS/TP communications when required. Fast, powerful, and fully distributed control allows complete independence from any other devices in the system. Firmware upgrades can be performed remotely. Easy startup and commissioning using the WebCTRL system user interfaces. Battery-backed real time-clock keeps time in the event of power failure or network interruption System Benefits. Connects seamlessly to the WebCTRL building automation system. Supports demand limiting and optimal start for maximum energy savings. ZN551 Zone Controller Zone Controller - The WebCTRL building automation system gives you the ability to understand your building operations and analyze the results. The WebCTRL system integrates environmental, energy, security and safety systems into one powerful management tool that allows you to reduce energy consumption, increase occupant comfort, and achieve sustainable building operations. Our web-based platform allows building managers to control and access information about their HVAC, lighting, central plant and critical processes on premises or remotely at any time of day.
