FANs 689.1, 635Product BulletinIssue Date 0301N30 Supervisory ControllerThe N30 Supervisory Controller is an economicalsupervisory controller designed to monitor andsupervise Heating, Ventilating, and AirConditioning (HVAC) equipment as well as lighting,security, and building access. The N30 efficientlysupervises the networking of Application SpecificControllers (ASCs) and provides buildingautomation features including time scheduling,alarm management, controller data exchange,energy management, and remote communications.Equipment operates at peak efficiency whilemaintaining optimum occupant comfort.Facility personnel can review the system statusand modify control parameters for theN30 Supervisory Controller and its associatedASCs using a VT100 Terminal, VT100 TerminalEmulator, or an M-Series Workstation.With the addition of a network card, multiple N30scommunicate over an Ethernet peer-to-peernetwork, providing increased functionality for morecomplex systems.Figure 1: N30 Supervisory ControllerFeatures and Benefits❑ Built-in EnergyManagement Features❑ Network-wide Interlocking❑ Peer-to-PeerCommunication❑ Dial-In – Dial-Out❑ Single Seat User Interface❑ Password ProtectionProvides advanced environmental controls forenergy cost-savingsSupports integrated control betweendistributed controllers for efficient operationWith a network card, provides directcommunication between devices usingBACnet® protocolAllows access to/from remote sites to ensureproper operationAllows operator to review entire system forfast and simple access to system dataProvides secure user access to system© 2001 Johnson Controls, Inc. 1Code No. LIT-6891050www.johnsoncontrols.com

Total distance between devices isapplication-specific. Network repeaters and otheraccessories, available through third-partysuppliers, may also be used.In addition to Johnson Controls HVAC controls, theN30 supports Metasys® compatible devices thatmonitor and control lighting, card access, andsecurity systems. The N30 supports many otherHVAC control components, including variablespeed drives, boilers, chillers, fire systems, andpower monitoring equipment.Built-in ApplicationsHVAC network controllers contain their ownroutines so each controller can performindependently. The breadth of this HVAC controllerline is unparalleled in the industry.2 N30 Supervisory Controller

EthernetM-Series WorkstationN30N30VT100N2N2UNT DX VMAVMADXUNTnetwork n30Figure 3: N30 Network ExampleNetwork ProtocolWith a network card installed, up to 50 N30s cancommunicate peer-to-peer using BACnetmessaging over the Ethernet bus. This meanseach node shares data and has access toinformation on all other controllers.Workstations can view data anywhere in thenetwork when connected on the Ethernet networkor connected directly to an N30.The BACnet protocol standard allows inter-vendorcommunication and easy system integration. TheAmerican Society of Heating, Refrigerating, andAir Conditioning Engineers (ASHRAE) defined thestandard and it is a requirement in manyapplications.BACnet ConformanceThe N30 communicates via BACnet, an industrystandard protocol developed by ASHRAE forintervendor communication.• Supports Annex J BACnet standard includingInternet Protocol (IP) support.• Protocol Implementation ConformanceStatement (PICS) is in the appendix of theN30 Supervisory Controller Technical Manual(FAN 689.1).• Fully meets Conformance Level 4, providingdata sharing and alarm management.• Interoperability is dependent on media type,protocol level, and conformance level.N30 Supervisory Controller 3

User Interface OptionsM-WebN30 Release 2.0 and later can be used withM-Web Release 3.0. M-Web provides aneconomical way for customers to increase systemaccess, locally or remotely, to a Metasys system.M-Series WorkstationsN30 Release 2.0 and later can be used withM-Series Workstations. These workstations allowthe N30 to:• connect via direct connection through serialport or over an Ethernet network• move through buildings, floors, and areas, bysimply pointing and clicking on symbols inM-Graphics• support trending, dynamic graphics,OLE for Process Control (OPC) andActiveX® interfacing, and much more, usingmultiple software components that areavailable to customize the workstation for eachsystem’s requirementsVT100 TerminalThe N30 can be accessed with a VT100 Terminalor a Personal Computer (PC) with a VT100Terminal Emulator. This option allows low cost:• direct or remote connection to the N30• support for text configuration of objectsFeature SetAlarm ProcessingWhen a point goes into alarm, the N30 sendsinformation to display the alarm point and anoperator-defined alarm message, allowing a fastresponse to any system problems.TrendingUser-defined Trend logs monitor the attributes ofspecified points over time. They are used to definesystem wide characteristics.TotalizationAnalog, Event, and Runtime Totalization objectsallow the tracking of consumable usage, numberof times specific events occur, and how longequipment remains in specified states.Remote Dial-In/OutThis feature allows remote access to your BuildingAutomation System (BAS) in order to:• set Alarm dial-out to a workstation or printerfor specified alarms• dial-in from M-Series Workstations or PC withVT100 emulation• dial-in for commissioning/troubleshootingUser AccessThe N30 Supervisory Controller identifieslegitimate users and their access privilegesthrough password identification. For authorizedusers, using the N30 is easy.Six levels of password protection are available.The authorization levels range from Configure toView Only. Access to the functions of the N30 isgranted according to the specific needs of a givenuser.4 N30 Supervisory Controller

Efficient Building OperationThe N30 is specifically tailored to meet the needsof building owners and managers who are lookingfor an affordable way to monitor and controlstandard mechanical systems such as:• dual-duct, single-duct, and packaged airhandling units• rooftop units, unit ventilators, heat pumps,chillers, and boilers• Variable Air Volume (VAV) systemsFlexible SchedulingThe N30 Weekly Scheduling feature allows theuser to define when an event should occur. Anevent can be programmed for any day of the week,holiday, or calendar date.Group ObjectsUsers may define groups for easy facilitymanagement. These groups include devices,points, or other objects according to the user’sneeds.Database ManagementUsers define a database offline or online, eitherdirectly connected to an N30, via the Ethernetnetwork, or from a remote site via a phone line.The users upload/download application specificcontrollers through the N30 without affectingsystem operations.Installation/HardwareSome of the installation and hardware features ofthe N30 include:• DIN rail or wall mount• non-volatile memory to archive all programsand data• communication and alarm Light-EmittingDiodes (LEDs) to allow easy troubleshootingNetwork-Wide System InterlockingInterlocking enables information from one or moreHVAC controllers to trigger a set of controlinstructions to be issued to other HVACcontrollers. It also allows analog or binary data tobe shared between controllers. For example, thisfeature could be used to eliminate the need for anoutdoor air temperature sensor wired to eachcontroller, saving hardware and installation costs.N30 Supervisory Controller 5
