APPENDIX A: Glossary of Terms

Terms used within the Specification Text:

• BACnet/IP: An approved BACnet network type which uses an Ethernet carrier and IP addressing.

• BACnet MS/TP: An approved BACnet network type which uses a Master-Slave Token Passing configu-ration. MS/TP networks are unique to BACnet and utilize EIA485 twisted pair topology running at 9600 to 76,800 bps.

• BACnet over ARCNET: An approved BACnet network type which uses an ARCNET (attached resource com-puter network) carrier. ARCNET is an industry standard that can utilize several speeds and wiring standards. The most common configuration used by BACnet controllers is an EIA485 twisted pair topology running at 156,000 bps.

• BACnet-N2 Gateway/Router

An approved BACnet to Johnson Controls N2 protocol translator and router emulating

BACnet N2 devices and points published under a virtual traditional BACnet network.

• Building Controller (BC): A fully programmable control module, which is capable of storing trends and schedules, serving as a router to devices on a subnet, and initiating read and write requests to other controllers. Typically, this controller is located on the Ethernet/IP backbone of the BAS. In many vendors' architectures a Building Controller will serve as a master control-ler, storing schedules and trends for controllers on a subnet underneath the Building


Section: 23 09 23

Date: 07/11/2019


Controller.

• Direct Digital Control (DDC): A control system in which a digital computer or microprocessor is directly connected to the valves, dampers, and other actuators which control the system, as opposed to indi-rectly controlling a system by resetting setpoints on an analog pneumatic or electronic controller.

• PICS - Protocol Implementation Conformance Statement: A written document, created by the manufacturer of a device, which identifies options specified by BACnet that are implemented in the device.

• Web services: Web services are a standard method of exchanging data between computer systems using the XML (extensible markup language) and SOAP (simple object access protocol) standards. Web services can be used at any level within a Building Automation System (BAS), but most commonly they are used to transfer data between BAS using different protocols or between a BAS and a non-BAS system such as a tenant billing system or a utility management system.

Terms used within typical Sequences of Operation:

• adj. Adjustable by the end user, through the supplied user interface.

• AI, AO, etc. (Column Headings on Points List) AI = Analog Input. A physical input to the control module. AO = Analog Output. A physical output from the control module. AV = Analog Value. An intermediate (software) point that may be editable or read-only. Editable AVs are typically used to allow the user to set a fixed control parameter, such as a setpoint. Read Only AVs are typically used to display the status of a control opera-tion. BI = Binary Input. A physical input to the control module. BO = Binary Output. A physical output from the control module. BV = Binary Value. An intermediate (software) point that may be editable or read-only. Editable BVs are typically used to allow the user to set a fixed control parameter, such as a setpoint. Read Only BVs are typically used to display the status of a control opera-tion. Loop = A control loop. Most commonly a PID control loop. Typically, a control loop will include a setpoint, an input which is compared to the setpoint, and an output which con-trols some action based upon the difference between the input and the setpoint. A PID


Section: 23 09 23

Date: 07/11/2019


control loop will also include gains for the proportional, integral, and derivative response as well as an interval which controls how frequently the control loop updates its output. These gains may be adjustable by the end user for control loop "tuning," but in self-tun-ing control loops or loops which have been optimized for a specific application the gains may not be adjustable. Sched = Schedule. The control algorithm for this equipment shall include a user edita-ble schedule. Trend. The control system shall be configured to collect and display a trend log of this object. The trending interval shall be no less than one sample every 5 minutes. (Change of Value trending, where a sample is taken every time the value changes by more than a user-defined minimum, is an acceptable alternative.) Alarm. The control system shall be configured to generate an alarm when this object exceeds user definable limits, as described in the Sequence of Controls. Note: If the specifications require use of the BACnet protocol, all of the above shall be provided as BACnet objects.

• Occupant Override Switch, or Timed Local Override: A control option that allows building occupants to override the programmed HVAC schedule for a limited period of time. When the override time expires, the zone returns to its unoccupied state.

• Occupant Setpoint Adjustment: A control option that allows building occupants to adjust - within limits set by the HVAC control system - the heating and cooling setpoints of selected zones. Typically, the user interface for this function is built into the zone sensor.

• Optimal Start-Up: * A control strategy that automatically starts an HVAC system at the latest possible time yet ensures comfort conditions by the time the building becomes occupied. In a typical implementation, a controller measures the temperature of the zone and the outside air. Then, using design heating or cooling capacity at the design outside air tem-perature, the system computes how long a unit must run at maximum capacity to bring the zone temperature to its occupied setpoint. The optimal start algorithm often includes a self-learning feature to adjust for variations from design capacity. A distributed system must use Run on Request with Optimal Start. (See below.)


Section: 23 09 23

Date: 07/11/2019


• Requested, or Run on Request: * A control strategy that optimizes the runtime of a source piece of equipment that sup-plies one or more receiving units - such as an air handler unit supplying zone terminal units with heating, cooling, ventilation, or similar service. Source equipment runs only when needed, not on a fixed schedule. The source equipment runs when one or more receiving units request its services. An operator determines how many requests are required to start the source equipment. For example, if all the zones in a building are unoccupied and the zone terminal units do not need heating or cooling, the AHU will shut down. However, if a zone becomes occu-pied or needs cooling, the terminal unit will send a run request to the AHU to initiate the start-up sequence. If this AHU depends on a central chiller, it can send a run request to the chiller. The run on request algorithm also allows an operator to schedule occupancy for individ-ual zones based on the needs of the occupants without having to adjust the schedules of related AHUs and chillers.

• Trim and Respond, or Setpoint Optimization: * A control strategy that optimizes the setpoint of a source piece of equipment that sup-plies one or more receiving units - such as an air handler unit supplying zone terminal units with heating, cooling, ventilation, or similar service. The source unit communicates with receiving units to determine heating, cooling, and other requirements, and then adjusts its setpoint. For example, if all zones are comfortable and do not request cooling, the AHU will grad-ually increase (trim) its supply air setpoint. When a zone requests cooling, the AHU re-sponds by dropping its setpoint. The more zones that request cooling, the more it drops the setpoint. The AHU repeats this process throughout the day to keep zones cool, but with a supply air setpoint that is no cooler than necessary.

Contracting Terms:

• Furnished or Provided: The act of supplying a device or piece of equipment as required meeting the scope of work specified and making that device or equipment operational. All costs required to furnish the specified device or equipment and make it operational are borne by the divi-sion specified to be responsible for providing the device or equipment.


Section: 23 09 23

Date: 07/11/2019


• Install or Installed: The physical act of mounting, piping or wiring a device or piece of equipment in accord-ance with the manufacturer's instructions and the scope of work as specified. All costs required to complete the installation are borne by the division specified to include labor and any ancillary materials.

• Interface: The physical device required to provide integration capabilities from an equipment ven-dor's product to the control system. The equipment vendor most normally furnishes the interface device. An example of an interface is the chilled water temperature reset inter-face card provided by the chiller manufacturer in order to allow the control system to in-tegrate the chilled water temperature reset function into the control system.

• Integrate: The physical connections from a control system to all specified equipment through an interface as required to allow the specified control and monitoring functions of the equip-ment to be performed via the control system.
