1.0 INTRODUCTION 1.1 Definition: Logical Point Mnemonic An alphanumeric string (name) that is used by the control system to reference any

physical attached end device (actuator/sensor etc.) as well as virtual (non-physical) points such as setpoints. The combination of letters and numbers is chosen so as to help one remember the function of the particular point.

1.2 Simple, obvious operation is the key to any successful energy management control

system (EMCS). Much of the ease of use is dependent upon the simplicity and consistency of the names chosen to represent the attached sensors and actuators. A balance must be struck between the difficulties associated with always having to key in very long but descriptive names, and the convenience of using a short but more cryptic mnemonic.

1.3 When systems are installed, a significant amount of time is used in the creation of

the database and control sequences. Much time is spent later in the fine tuning of the sequences. All this activity necessitates a mnemonic scheme which does not hamper the operator in the understanding of the programmed strategies.

1.4 Most systems offer graphic packages which reduce much of the tedious keyboard

entry. At first glance this could imply that there is little need to pay attention to the length of point names. Unfortunately the graphics, however easy to use, must be configured and maintained by someone. In many instances that person is the building operator. Since most operators are chosen for their HVAC/operations knowledge not their keyboarding skills, it is still important to strike a suitable balance.

1.5 A universally applicable scheme is desirable in order to allow operators from

various facilities to easily exchange control strategies. Such a standard also decreases the difficulties of staff migration and enables support staff to more easily assist the various areas.

1.6 The purpose of a building control system is to continuously monitor various

physical properties and manipulate mechanical devices so as to maintain the desired conditions as determined by the programming. The desired conditions are often indicated by virtual set points relating to the physical property under control. Since all this activity relates to actual physical equipment, it is only reasonable that the mnemonic standard be based on this equipment, not the inner workings of the controller. The name should answer the following questions:


4

1) What building (only for multi-building site)? 2) What mechanical system ? 3) What zone if terminal equipment is associated with the system? 4) What end device (i.e. valve, damper, sensor)? 5) Does the function of the point require some special emphasis?

1.7 The questions above indicate a three or four level logical point mnemonic and, for

some points, an appended fifth level function indicator or attribute.

Level 1: Provides information as to what building contains the point. This level is not required for the usual single building installations.

Level 2: Specifies the mechanical system to which the point is associated. Level 3: Specifies the point directly associated with the mechanical system

described by the level 2 mnemonic.

1.8 There are many cases where the point is not directly associated with the mechanical system described by the level 2 mnemonic, such as in the case of terminal control units that service additional equipment associated with the main system. An example of this is a variable volume air system and its affiliated VAV box controllers.

If the point is connected to terminal equipment affiliated with the system,

described by the level 2 mnemonic, then the level 3 mnemonic would describe the type of terminal controller and its location. Level 4 would then be required to specify the point.

Level 3: Specifies the terminal equipment associated with the mechanical system

described by the level 2 mnemonic. Level 4: Specifies the point associated with the terminal equipment described by

the level 3 mnemonic.

1.9 If the point represents some associated function with respect to another point or to the system as a whole then an attribute indicator is appended to the previous levels. A separating delimiter is mandatory.

Attribute: Specifies the special function of a physical or virtual point.

1.10 All of the above levels need not be present in a point name. A point name may be

composed of as little as two levels; system and point.


5

2.0 PHYSICAL POINTS - SPECIFICS 2.1 The logical point mnemonic is to be an alphanumeric code composed of three

levels if the point is directly associated with the mechanical system.

BUILDING This level is used only if more than one building is under the control of a single EMCS. A one or two character abbreviation is used to designate each building within the system. Examples:

BB Bowker Building HB Haultain Building PW Pedway SYSTEM This level uses a two character mnemonic to break out the major

mechanical systems within the facility. A third character is allowed, but not required, in order to enable like systems to be separated. Examples:

AH1 Air Handler 1 VVS Variable air Volume system South POINT This level uses a three to four character mnemonic to describe the

actual point that is to be controlled. The fourth character is allowed in order to enable the separation of multiple like final control elements or sensors. The additional character is also used in more complex systems where there are many points on a piece of equipment such as a boiler. Examples:

MAT Mixed Air Temperature CCV Cooling Coil Valve BSP Branch Static Pressure (if only one) BSP2 Branch Static Pressure 2 B3HF Boiler 3 High Fire B2FF Boiler 2 Flame Fail

2.2 The logical point mnemonic will need to be an alphanumeric code composed of

four levels if the point is connected to a terminal controller or other associated piece of equipment affiliated with the mechanical system.

BUILDING As above. SYSTEM As above.


6

TERMINAL This level uses a single character mnemonic to indicate the type UNIT of terminal unit (B for Box, etc) followed by up to three characters

which are used to separate the units. Examples: B216 - Box for room 216 TERMINAL This level uses a 1 to 3 character mnemonic to describe the actual POINT point that is to be controlled. These mnemonics follow the same

convention as for other point names. Examples:

C Compressor in heat pump unit CCV Cooling Coil Valve in induction units D Damper in dual duct or VAV unit F Fan in fan powered units HCV Heating Coil Valve in induction units PRV Perimeter Radiation Valve RCV Reheat Coil Valve in terminal reheat units RPV Radiant Panel Valve RV Reversing valve in heat pump unit SAF Supply Air Flow rate of VAV unit SAT Supply Air Temperature of terminal unit ST Space temperature V Valve (miscellaneous functions)

2.3 For physical points, appending attributes are most often used to clarify the

intended function of the point such as in the naming of status points. Special purpose transducers, where the output cannot be ranged to a proper engineering unit without going through a program, require an appending attribute as well. Example: If AH1SAF is to be the mnemonic for the final calibrated supply air flow rate, then the actual non-linear or uncalibrated physical input point would be named AH1SAF-T. Common attributes: A Amps - motor or device current from current transducer or drive output. E Enable - a point that allows a piece of equipment to run under the control

of some hardwired local device or its packaged controls. F Fault - fault alarm from variable speed drive or packaged controller O Override – device override or local controls override status. S Status - device status from packaged controller or motor status from

differential pressure or current switch etc. R Reset - setpoint reset to packaged controller (control point adjust). T Transducer - general nonlinear, uncalibrated or special purpose input. A delimiter is mandatory so as not to cause confusion with other point mnemonics. For example: AH1SFS Is this supply fan status or supply fan speed ? The delimiter can be any allowed non-alphanumeric character, but the use of a minus sign “-“ or an underscore “_” is highly recommended. If these are not allowed then the forward slash “/” has been found to be an acceptable alternate.


7

2.4 The complete logical point mnemonic is formed by combining all levels sequentially. Examples:

LCAH1MAT XX ---------- Building: Law Courts XXX ------- System: Air Handler #1 XXX ---- Point: Mixed Air Temperature LCVVSB216SAF XX ---------- Building: Law Courts XXX ------- System: Variable Volume South XXXX --- Term unit: Box for room 216 XXX Point: Supply Air Flow rate In a single building system the complete logical point mnemonic would omit the

first level. Examples: AH1MAT XXX --------- System: Air Handler #1 XXX ------ Point: Mixed Air Temperature VVSB216SAF XXX --------- System: Variable Volume South XXXX ----- Term unit: Box for room 216 XXX -- Point: Supply Air Flow rate BSP1 XX ---------- System: Boiler System XX -------- Point: Pump #1 BSP1-S XX ---------- System: Boiler System XX -------- Point: Pump #1 X ------- Delimiter X ------ Attribute: Status BSB3-E XX ---------- System: Boiler System XX -------- Point: Boiler #3 X ------- Delimiter X ------ Attribute: Enable VVSSAF-T XXX --------- System: Variable Volume South XXX ------ Point: Supply Air Flow rate X ----- Delimiter X ---- Attribute: Transducer


8

2.5 Except for the appending attribute characters, levels within the mnemonics should not be separated by spaces or other punctuation, unless absolutely required by the system. Their addition adds little to comprehension but significantly increases the number of keystrokes used in creating programming or editing database.

2.6 The building portion of the mnemonic is not necessarily for single building

applications. 2.7 As a general rule, each character in the logical point mnemonic represents one

word used to describe the point. Examples: AH1CCV Air Handler 1 (system), Cooling Coil Valve (point) HWSWT Heating Water (system), Supply Water Temperature (point) VVNMAD Variable Volume North (system), Mixed Air Dampers (point) 2.8 Where glycol is used in place of water, “G” replaces “W”. Example:

BSSWT Boiler System Supply Water Temperature BSSGT Boiler System Supply Glycol Temperature

2.9 There are always a few alarm points, such as an elevator sump level, that are

difficult to place with any particular mechanical system. These miscellaneous points are best placed together under system name MIS.

3.0 VIRTUAL POINTS - SPECIFICS 3.1 Definition: Virtual point A numeric variable (value stored in computer memory), that has associated with

it, data similar to that of a real physical point. This variable can be commanded or used in control programs. It can be assigned units as well as any other normal database information but is not a real physical point.

3.2 The basic uses for these points are:

.1 Global virtual points are used to set building operating modes or calculate

values that are used by many systems .2 System virtual points associated with physical points or mechanical

systems to provide information such as operating flags, setpoints, controller gains, user adjust values and max/min/average/effective space conditions.

.3 Local virtual points used to hold intermediate calculated information such as factors used in determining setpoints.

.4 Speciality virtual points that are used in the calculation of information that is further used to produce some global flags or the like. An example would be the point mnemonics used in an outside air temperature projection routine.


9

3.3 Global virtual points, by their nature, are used in the control sequences of many

mechanical systems. They are used to summarize information for operator use and to totalize values, obtained from many smaller systems, for use by a building wide system such as the heating or cooling systems. These points are usually included on at least one graphic screen. Although the way many of these values are determined may be complex, their use is usually obvious. As such, many have been given simple word like mnemonics. The following are some recommended mnemonics that have evolved over time and are in common use: GLOBAL BUILDING TEMPERATURE TARGETS & OPERATING MODES STOBJ Space temperature objective STOBJ_UA STOBJ user adjust OCCUPIED Occupied mode flag PURGE Purge mode flag PREHEAT Preheat mode flag PRECOOL Precool mode flag GLOBAL INFORMATION HTGDMND Overall heating demand (sum of all air sys heating demands) CLGDMND Overall cooling demand (sum of all air sys cooling demands) ST_MAX Maximum building space temperature in the building ST_AVG Average building space temperature ST_MIN Minimum building space temperature ST_EFF Effective building space temperature CRTIME Calculated real time (decimal hours) if not provided by

control system) 3.4 A larger building is often split into various areas with a dedicated air handling

system serving each area. If each of these areas has differing occupancy schedules, it is possible to have a separate set of operating mode flags for each area as follows: STOBJ# Space temperature objective for area # STOBJ#_UA User adjust for STOBJ for area # OCCUP# Occupied mode flag for area # PURGE# Purge mode flag for area # PREHEAT# Preheat mode flag for area # PRECOOL# Precool mode flag for area #


10

3.5 System virtual points usually relate to some function associated with the control of a physical property. They should be named similarly but with an extension that describes the function being performed. The following appending attribute mnemonics are recommended: _SP setpoint _GO system go flag _UA user adjust _RT run time _CO controller _HL high limit _PG controller proportional gain _LL low level _IG controller integral gain _ALM alarm _DG controller derivative gain _LEAD lead/lag flag _MAX maximum _AVG average _MIN minimum _EFF effective

3.6 Setpoints and controllers are named after the controlled variable, not the device

doing the controlling. (i.e. AH1CCV_SP is meaningless) An example of supply air temperature control follows: AH1SAT Supply Air Temperature (physical point) controlled variable AH1SAT_UA Supply Air Temp User Adjust (an offset applied to setpoint) AH1SAT_SP Supply Air Temperature SetPoint AH1SAT_CO Supply Air Temperature COntroller AH1SAT_PG Supply Air Temperature controller Proportional Gain

3.8 More examples of common system virtual point mnemonics: AH1_GO Air Handler 1 GO flag (“yes” to run AH1, “no” to stop AH1) AH1MAD_MIN Minimum desired position for AH1 mixed air dampers AH1SF_RT Run time for AH1 supply fan BSRWT_LL Boiler system return water temperature low limit BSSWT_HL Boiler system supply water temperature high limit BSRWT_ALM Boiler system low return water temperature alarm

3.9 As alluded to in global virtuals above, some system points are necessary to pass

information that will be summed or manipulated in some fashion by a more global routine. Examples of some of these are: AH#CDMND Cooling demand value from air system AH# AH#HDMND Heating demand value from air system AH# AH#ST_MAX Maximum space temperature in zones served by AH# AH#ST_AVG Average space temperature in zones served by AH# AH#ST_MIN Minimum space temperature in zones served by AH# AH#ST_EFF Effective space temperature in zones served by AH#


11

3.10 The uses for local virtual points are so varied that no standard can be proposed. Sound judgement should be used in coming up with mnemonics that fit within the overall scheme yet succinctly describe their use. These points are rarely shown on a graphic screens. Since most uses are sufficiently complex, program comments are required to explain their function. As such, long descriptive mnemonics are not required because the program comments should already explain their purpose in detail. Examples: AH1SAT_SPF1 Factor 1 in the calculation of AH1 Supply Air Temp Setpoint AH1MAD_OALF Outside air temp linearization multiplication factor.

3.11 Over the years some speciality calculations have become somewhat standard and

the virtual points mnemonics used have been standardized as well. A good example is the outside temperature projection routine: SPECIALITY VIRTUAL POINTS OAT Temperature selected or calculated for use in projector. OATPHT Projected high temperature OATPLT Projected low temperature OATHDH Hour of day's high temperature OATHDL Hour of day's low temperature OATYTD Yesterday's temperature difference OATDH Day's high OATDL Day's low WARMDAY Warm day flag COLDDAY Cold day flag

4.0 STANDARD FOR LOGICAL POINT MNEMONICS

The following articles and tables attempt to list the majority of possible point mnemonics for the most common building mechanical systems. It is unlikely that any one mechanical system will contain all the points listed. Some are mutually exclusive (e.g. supply fan vanes and supply fan speed), others are simply not common. It is also unlikely that all necessary point mnemonics will be found in this document. Some creativity will be required to create the new names in such a way as to conform to the basics of this standard. The mnemonics are provided to assist in naming the points used in a particular design, NOT as a guideline to create the design.


12

Allowed number of characters:

BUILDING SYSTEM SYS POINT TERM POINT ATTRIBUTE 1-2 1-3 2-4 1-3 1-4

NOTE: Physical/hardware point attributes such as amps, enable, fault, override,

reset, status and transducer are always 1 character in length. Attributes used in virtual points such as setpoint, user adjusts and others are always 2 or more characters in length.

4.1 BUILDING LEVEL MNEMONICS

This level is used only if more than one building is under the control of a single EMCS. A one or two character abbreviation is used to designate each building within the system.

4.2 SYSTEM LEVEL MNEMONICS

This level uses a 2 to 3 character abbreviation to identify a particular mechanical system. A “* “ in the following lists indicates that an additional character or number can be used to help identify a specific system when more than one of a particular type exists. E.g. AH1, AH2, AH3 etc.

4.2.1 Air Systems

AH* Air Handler – constant volume single zone or terminal reheat DD* Dual Duct IS* Induction System MU* Makeup air Unit MZ* MultiZone VV* Variable air Volume

4.2.2 Cooling Systems CT* Cooling Tower CW* Chilled Water DC* Dry Cooler – subset of points required for CT*

4.2.3 Electrical Systems LS* Lighting System – used only if there are many lighting points PD* Power Distribution – includes emergency generator PL* Parking Lot

4.2.4 Heating Systems BA* Boiler Air – combustion air for boiler room BS* Boiler System – large systems, boilers and supporting equipment HE* Heat Exchanger HW* Heating Water – includes boilers in simpler systems PR* Perimeter Radiation – if complex or on separate loop RP* Radiant Panel – if complex or on separate loop TR* Terminal Reheat – if complex or on separate loop

4.2.5 Other Systems CA* Control Air DCW Domestic Cold Water DHW Domestic Hot Water FA Fire Alarm – may include smoke exhaust points FP Fire Protection – Sprinklers etc. – may be rolled into fire alarm system HP Heat Pump OA* Outside Air information – temp, hum, projected conditions etc. PG* Parking Garage – combines CO sensors, exhaust fans and makeup units SH* Space Humidity – if monitoring/controlling separate spaces (museums) ST* Space Temperature – if not associated with any particular air system

MIS Miscellaneous – for odd points that don’t fit in elsewhere - e.g. elevator sump alarms,

4.3 POINT LEVEL MNEMONICS The actual point mnemonic portion may consist of up to three levels depending on how the point relates to the mechanical system. A physical point directly associated with a system would consist of a single level representing the point with 2-4 characters. A terminal point will require a 2-4 character terminal box identifier followed by 1-3 characters representing the actual point. Finally, any of these can be followed by an appending attribute. In any case, room has been left for an additional number or letter to distinguish multiple like points. For example, if an air system has two supply fans then one would likely be named SF1, the other SF2. In a similar fashion, if a wetted media humidifier were split into three sections with a solenoid for each portion, then the solenoids would be named SH1, SH2, SH3.

4.3.2 Air System: AH* (Air Handler – Self Contained Packaged Controls)

Some small air systems and most gas fired makeup air units contain their own packaged control system. These usually allow external start/stop or enable control and usually provide contacts for system status and possibly an alarm. Most can also be fitted so as to accept an external signal for resetting the system’s supply air temperature setpoint.

4.3.15 Heating System: BS* (Boiler System) This system mnemonic is intended for large or complicated systems with many boilers. Since many points are associated with each boiler, it is possible to treat an individual boiler in the same manner as terminal equipment. This also makes it possible to use the same naming scheme in smaller systems where the boiler points are included in the Heating Water system.
