1.2 DEFINITIONS 1.2.1 Digital Controller 1.2.1.1 Interoperable Digital Controller (IDC) A control module which is microprocessor based Interoperable LonMarkTM or LonWorks. HVAC control is accomplished using LonMarkTM based devices where the application has a LonMarkTM profile defined and performs stand-alone operations.

1.2.1.2 Interoperable BACnet Controller (IBC) A control module which is microprocessor based Interoperable BACnet Controller in accordance with ASHRAE 135. IBC's must be provided with product interoperability compliance statement documents that demonstrate the compliance level to the ASHRAE 135.


1.2.2 Direct Digital Control (DDC) Digital controls, as defined in this specification, performing control logic. The controller directly senses building environment and makes control decisions based on user defined, controller resident programs. The controller outputs control signals that directly operate valves, dampers, and motor controllers. No conventional control devices, such as receiver-controllers, thermostats, and logic units are present within or interface with a direct digital control loop. Actuators are electric and the controller output is converted to the appropriate type of signal.

1.2.3 DDC System A system made up of one or more interoperable digital controllers which communicate on a network.

1.2.4 Distributed Control The intent of distributed control is to install the controllers near their respective controlled equipment. The control system consists of stand-alone controllers, with the total number of input and output points limited to 48 or less per controller. Failure of any single controller will not cause the loss of more than 48 control points.

1.2.5 Dynamic Control A process that optimizes energy efficiency of HVAC systems (air handling units, converters, chillers, and boilers) by increasing and decreasing setpoints or starting and stopping equipment in response to heating and cooling needs of the facility. A requirement of dynamic control is knowing the heating/cooling demand status of the process. Therefore dynamic control requires controllers connected in a communications network and receiving feedback, necessary variable point data and/or actual status input to accomplish closed loop control.

1.2.6 Firmware Firmware is software programmed into read only memory (ROM) and erasable programmable read only memory (EPROM) chips. Software may not be changed without physically altering the chip.

1.2.7 Graphic User Interface Software (GUI) Graphic user interface software shall run on Microsoft Windows Vista service Pack 1, or later. The GUI employs browser like functionality that includes a tree view (similar to Windows Explorer) for quick viewing of, and access to, the hierarchical structure of the database. Pull down menus and toolbars employ buttons, commands and navigation that permit the operator to perform tasks with a minimum knowledge of the HVAC Control System and basic computing skills. These include, but are not limited to, forward/backward buttons, home button, and a context sensitive locator line (similar to a URL line), that displays the location and the selected object definition.

1.2.8 Hand-Held Terminal A hand-held terminal is a manufacturer specific device connected directly to a communications port on a controller, through which the controller is


accessed and, in some cases, programmed. This style of interface is not an acceptable installation on Fort Lewis.

1.2.9 Input/Output (I/O) Points I/O points refer to analog inputs (AI), digital inputs (DI), analog outputs (AO), and digital outputs (DO) in a digital controller. Another term for digital inputs and outputs is binary inputs and outputs. Inputs are from analog sensors (temperature, pressure, humidity, flow) and digital sensors (motor status, flow switches, switch position, and pulse output devices). Outputs operate modulating and on/off control devices.

1.2.10 I/O Expansion Unit An I/O expansion unit provides additional point capacity to a digital controller and communicates with the stand-alone digital controller on a LAN. An I/O unit is not stand-alone because the control program does not reside in the I/O unit. An I/O expander which connects directly to a stand-alone controller through a multi-line microprocessor bus is restricted to reside within 3 feet of the stand alone controller and is considered part of the stand alone controller. The total point count of the I/O and all connected expansion units shall not exceed the 48 point limit.

1.2.11 Local Area Network (LAN)

a. A communications bus that interconnects digital controllers for peer-to-peer (see "peer-to-peer" below) communications. Different levels of LANs are possible within a single DDC system. In this case, a digital controller on a higher level LAN acts as a network controller to the controllers on the lower level LAN. The network controller, then, has at least two LAN communications ports. One port supports peer-to-peer communications with other digital controllers on the higher level LAN. The other port supports communications with the digital controllers on the lower level LAN.

b. LANs permit sharing global information. This allows building and

site wide control strategies such as peak demand limiting, dynamic control strategies, coordinated response to alarm conditions, and remote monitoring and programming of digital controllers.

c. The controllers peer-to-per communications bus is commonly referred

to as "the field bus."

d. The "LAN" typically refers to the communications bus using the ethernet protocols (Category 6) within a building.

1.2.12 Microprocessor A microprocessor refers to the central processing unit (CPU) that contains all registers and logic circuitry that allow digital controllers to function.

1.2.13 JACE (Java Application Control Engine) Network Area Controller (NAC) The Jace network area controller (NAC) provides the interface between a higher level LAN or WAN and the interoperable digital controllers, providing global supervisory control functions. NAC's provide multiple user access at


varying levels through password protection. The Jace shall not be used to control major HVAC equipment or systems.

1.2.14 LonMark See LonMark International. Also, a certification issued by LonMark International to CEA-709.1B devices.

1.2.15 LonMark International Standards committee consisting of numerous independent product developers and systems integrators dedicated to determining and maintaining the interoperability guidelines for the LonWorks industry. Maintains guidelines for the interoperability of CEA-709.1B devices and issues the LonMark Certification for CEA-709.1B devices.

1.2.16 LonWorks The overall communications technology, developed by Echelon Corporation, for control systems. The term is often used to refer to the technology in general, and may include reference to any/all of the: protocol, network management, and interoperability guidelines where the technology is based on the CEA-709.1B protocol and employs interoperable devices along with the capability to openly manage these devices (via multiple vendors) using a network configuration (or service) tool.

1.2.17 Output Signal Conversion Output signal conversion refers to changing one kind of control output into a proportionally related signal appropriate for direct actuation of the controlled device. An example is converting a 4 to 20 mA or 0 to 10 VDC signal to a proportional 20 to 103 kPa (3 to 15 psig) signal to operate a pneumatic actuator.

1.2.18 Optimum Start Optimum start is a method of starting HVAC equipment prior to scheduled occupancy in order to have the building at setpoint when occupied. Optimum start is based on the zone temperatures, zone setpoints, and outdoor temperature.

1.2.19 Peer-to-Peer Peer-to-peer refers to controllers connected on a communications LAN typically referred to as the "field bus" that act independently, as equals, and communicate with each other to pass information.

1.2.20 Performance Verification Test The performance verification test (PVT) is the formal commissioning of the DDC system performed after successful contractor field testing and prior to the second phase of DDC training. It is used as a means for final acceptance of the control system and provides a means to verify the system functions are performing IAW (in accordance with) the manufacturers written instructions, sequence of operation and control drawings.


1.2.21 PID PID refers to proportional, integral, and derivative control; the three types of action that is used in controlling modulating equipment.

1.2.22 Resolution Refers to the number of possible states an input value or output value can take and is a function of the digital controller I/O circuitry; the A/D converter for input and the D/A converter for output. Ten bit resolution has 1024 possible states.

1.2.23 Stand-Alone Control Refers to the digital controller performing required climate control, and energy management functions without connection to another digital controller or computer. Requirements for stand-alone control are a time clock, a microprocessor, resident control programs, PID control, and I/O. All stand-alone controllers have a communication port and firmware for direct connection and interrogation with a laptop computer. This interrogation includes parameter changes and program downloads.

1.2.24 Terminal Control Unit (TCU) An off-the-shelf, stand-alone digital controller equipped for communication on a lower level LAN. TCUs may deviate from stand-alone only in receiving energy management and time information from a stand-alone digital controller. A TCU is commonly application specific and is used for distributed control of specific HVAC subsystems. A TCU communicates with other digital controllers. Typically, a TCU communicates on a lower level LAN. Examples where TCUs are used include small air handling units (AHUs), variable air volume (VAV) boxes, fan coil units, and heat pumps. TCUs shall be LonMark/Lonworks or BACnet-based. All TCUs shall be remotely configurable via the Ft Lewis WAN (Wide Area Network).

1.3 TEMPERATURE CONTROL AND FACILITY MANAGEMENT AND CONTROL SYSTEM The building's Temperature Control System (TCS) shall be capable of being extended to the existing Fort Lewis Niagara Framework Utilities Management and Control System (UMCS), and comprised of a network of interoperable, stand-alone digital controllers communicating via LonMark/LonTalk and/or BACnet communication protocols to a Jace Controller Network Area Controller (NAC). The JACE Controller to be connected to the UMCS through the NEC switch. NEC switch not within the Scope of the contract. Cat-6 wiring to switch to be provided by Contractor. Access to the system shall be accomplished through standard Web browsers and/or local area network, and/or WAN.

The TCS shall be comprised of a network of interoperable, stand-alone digital controllers communicating to a host computer within one facility within the project using graphical user interface software. The UMCS shall communicate to third party systems such as chillers, boilers, air-handling systems, energy metering systems, other energy management systems, access control systems, fire-life safety systems and other building management related devices with open, interoperable communication capabilities.


Provide a TCS including associated equipment and accessories as specified. Manufacturer's products, including design, materials, fabrication, assembly, erection, examination, inspection, and testing shall be in accordance with ASME B31.1 and NFPA 70, except as modified herein or indicated otherwise. Routers and /or gateways between the JACE NAC or workstation computer to the Ft Lewis Wide Area Network (WAN)/ Local Area Network (LAN) shall not be utilized due to security restrictions.

The TCS systems shall maintain stable temperature control and all other conditions as indicated. The end-to-end accuracy of the system, including temperature sensor error, wiring error, A/D conversion, and display, shall be 0.5 degree C or less.
