Complete HVAC connectivity using the BACNET protocol
Finally—HVAC equipment with open communications
Complete connectivity is the goal of every controls designer and owner: controls that connect and communicate seamlessly with other control systems. That goal has finally been realized for HVAC control. YORK® is the first HVAC manufacturer to offer a control system that provides native BACnet® connectivity from the smallest terminal unit to the largest chiller.
ISN ConneXsys™ controls all speak BACnet®
For network devices to communicate clearly
and efficiently, they all must speak the same
language, and ISN ConneXys controls do!
The basis of YORK’s control communication
is BACnet—the open protocol that has
become the popular standard for building control connectivity.
In the past, many HVAC manufacturers
offered controls that spoke only their ownproprietary language. Recently, some have
responded to BACnet’s popularity by offering
translators that convert their proprietary
language to BACnet. Others offer BACnet
capability, but only for portions of their systems.
In contrast, ISN ConneXsys controls provide
complete connectivity by speaking native
BACnet at every level of control.
ISN ConneXsys controls help reduce costs
Because they speak BACnet right out of the box, ISN ConneXsys controls help cut the capital cost of buying, installing, and commissioning translators to convert proprietary languages to BACnet. Installation costs can be reduced, because time is not wasted resolving interoperability conflicts—ISN ConneXsys controls are BACnet compatible. Their Auto Discovery ability automatically reports device parameters upon connection with the network—including non-YORK BACnet devices. This feature eliminates laborious entry of device addresses into routing tables.
ISN ConneXsys controls offer greater flexibility
A proprietary network protocol hampers a control system’s ability to grow and adapt. Only controls that speak that proprietary language can be easily integrated, which puts severe constraints on network design. But ISN ConneXsys controls can be added to existing BACnet systems without fear of connectivity problems. Because BACnet is embraced by controls suppliers, installation of ISN ConneXsys controls will not limit the choice of future additions to a control system.
Controls that are simple, swift, and smart
Simple: ISN ConneXsys components can be connected by common, twisted-pair cable. Auto Discovery ability recognizes devices automatically, so no manual configuration is required at the Operator Work Station.
Swift: 38,400 bits per second throughput can handle significant program messages; provide real-time access to information within the network.
Smart: Allow for subsystem integration, including lighting, smoke control, power, refrigeration, and access control; Internetready, so they can stay current with emerging technology and innovations.
Easier operation
ISN ConneXsys controls offer easier operation
thanks to the Operator Work Station, which
offers the finest graphical-user interface in
the industry. Equipment graphics are displayed
in a realistic and animated format. A global
perspective lets you monitor the entire network
from one location. A glance at the graphics shows
the current state of any zone or component. An accurate picture allows operational problems to
be easily identified and operators quickly trained.
Internet connectivity reduces costs and response times
ISN ConneXsys technology takes advantage
of BACnet/IP to provide remote access of
control systems over the Internet. Displays,
setpoints, reports, and schedules can be
managed anywhere there is Internet access.
Labor costs can be reduced because real-time
information can be accessed at remote sites.
Alarms can be sent automatically to email, cell
phone, or pager—even to multiple devices.
So information is easily accessible after hours.
Connect multiple buildings
The ISN ConneXsys system takes advantage
of BACnet’s extensive network capabilities.
As a result, you can create a BACnet network
that ties together multiple remote buildings
over your existing campus-wide internetwork.
No custom hardware or software is needed
for integration. Best of all, one ISN ConneXsys
Operator Work Station can operate your
entire campus.
Control experience that spans decades
Born of our commitment to advanced HVAC technology, YORK control systems were introduced in 1982 to meet customer demands for both HVAC and facility controls. Today, thousands of customers in the US—including IBM, Kodak, Ford and Caterpillar—have chosen YORK to control HVAC and building installations. Worldwide, YORK controls are in use in over 100 countries—evidence of our capability to apply control solutions globally
Utilized successfully in a wide range of applications
Over the years, YORK controls have been applied on tens of thousands of projects worldwide. Facilities include: hotels, laboratories, office buildings, shopping centers, hospitals, sporting venues, airports, and manufacturing plants.
Single-source responsibility
YORK can provide all parts of the system, from top to bottom. As a result, controlsystem designers and owners can rely on one expert point of contact—YORK— for equipment integration, network design and deployment, and BAS interface and implementation. Consequently, you get components, expertise, service, and support which totally eliminates annoying and timewasting finger-pointing if problems arise.
An advanced product line that has you covered
Only YORK offers a cost-effective product range that elevates BACnet compatibility to a new level—every level! At the equipment tier, ISN ConneXsys controllers are available for VAV and fan-coil units, air-handling units, chillers, boilers, and towers. At the network tier, ISN ConneXsys routers and repeaters are available to extend communication rangeand connect to your facility’s Ethernet network, and even the Internet. Finally, at the supervisory tier, our native BACnet devices easily integrate with the Operator Work Station to provide a powerful, but simple control solution. That’s why YORK can truly meet all your application needs, from smallest to largest and from top to bottom.
