SUPERVISORY CONTROL IMPLEMENTATION
1. GENERAL. The programs described in Chapter 7 can be applied to existing or new systems. Most
of these programs may be applied to several types of systems, but others may only be applicable to
special types of systems. For example, the boiler monitoring and control program is only applicable to
facilities with boiler plants. Due to the interactive nature of the programs, the inputs and/or outputs of one
implemented program may provide inputs to other programs.
2. INSTRUMENTS AND INPUTS. Certain instruments and inputs can be common to an entire building
or, in some cases, the entire UMCS. Electrical consumption and demand instrumentation do not need to
be duplicated except in special cases, such as when a UMCS serves an extremely large geographical
area, or multiple utility substations. When applications require OA measurement, the minimum
requirement is one OA temperature and one RH instrument (when used) for each building. However, the
designer may need to increase the minimum requirements to satisfy site specific building and system
conditions. For example, separate OA instruments will be specified where intake temperatures of the OA
measured on a roof mounted unit may vary significantly from other air intake locations, causing erroneous
3. DIAGRAMS. Graphic diagrams of typical systems showing UMCS devices and functions for
defined by the designer for each system's controlled devices in the event of a field equipment panel
malfunction. Failure modes will be based on climate, type of system, and user requirements. The failure
corresponding database tables, are provided for illustrative purposes only.
4. TABLES. Database tables listing UMCS software and settings applied to typical systems are
system to be controlled or monitored by the UMCS. Two or more identical systems within the same
building, having the same occupancy schedule, may be listed on the same database table. The table's
contents will be tailored to the system being controlled for each specific application.
5. SYMBOLS AND ABBREVIATIONS. A listing of symbols and abbreviations used in the system
schematics is provided in Appendix B.
6. ADDITIONAL APPLICATIONS. Additional utility systems monitoring and control applications which
have been provided through UMCS, and which have proven beneficial in energy savings, demand
savings, labor or other cost savings, are listed below. Each application listing includes typical monitored
or controlled parameters. Additional applications will be evaluated for feasibility on individual UMCS
