**Infoscan Applications Software**

-   Optimum Start/Stop Program

Various start/stop times daily based on ambient conditions to optimize
energy utilization.

-   Report Generator

Develops reports related to any system data over any selected period of
time.

-   Time of Day Scheduling

Automated scheduling to control equipment off or on, or initiate
computer sequences at designated time.

-   Calculated Point

Data points derived from telemetered values and utilized to drive
software applications throughout the system.

-   Analog Totalization

Totalizes values of analog points over selected time periods.

-   Historical Data Collection

Documents historical data for any database point within the system over
any selected period of time.

-   Trend Logs

Provides convenient format for printing logs of selected database values
over selected periods of time.

-   Energy Totalization

Calculates heat energy in BTU's for energy source consumed by specified
mechanical systems.

-   Duty Cycling Program

Deactivates equipment for predetermined periods of time during building
occupied hours based on a zone temperature setpoint.

-   Demand Limiting Program

Automatically sheds electrical loads to prevent exceeding an electrical
demand peak value.

-   Day/Night Setback Program

Limits the rise or drop of space temperature during unoccupied hours and
maintains a minimum value based on a lowered setpoint and zone
temperature reference point.

-   Enthalpy Program

Reduces the HVAC system cooling requirements when the enthalpy of the
outside air is less than that of the return air.

-   Economizer Program

Reduces HVAC system cooling requirements when the outside air dry bulb
temperature is less than the return temperature minus an
operator-defined deadband.

-   Ventilation Requirement Program

Reduces the HVAC system thermal load during warm-up or cool down cycles
prior to occupancy of the building and during day/night setback periods.

-   Hot Deck/Cold Deck Temperature Reset Program

Resets the hot deck/cold deck temperatures in dual duct and multizone
HVAC systems by setting minimum temperature differential based on
monitor of all zone conditions.

-   Reheat Coil Reset Program

Selects the zone with the least amount of heat required. Resets the cold
deck discharge temperature upward until it satisfies the zone with the
lowest demand, or until the zone humidity control requirements cannot be
met.

-   Steam Boiler Selection Program

Selects the most efficient boiler or combination of boilers based on
boiler operating data to satisfy the heating load.

-   Hot Water Boiler Selection Program

Selects the most efficient boiler or combination of boilers based on
boiler operating data to satisfy the heating load.

-   Hot Water Air Reset Program

Resets the hot water temperature supplied by the boiler of converter in
accordance with the outside air temperature.

-   Chiller Selection Program

Selects the most efficient chiller or combination of chillers based on
chiller operating data to satisfy the cooling load.

-   Chiller Water Temperature Reset Program

Resets the chilled water temperature supplied by a water chiller upward
until the required space temperature or humidity setpoints can no longer
be maintained.

-   Condenser Water Temperature Reset Program

Resets the condenser water temperature from a fixed temperature downward
when the outside air wet bulb temperature will produce lower condenser
water temperature.

-   Chiller Demand Limit Program

Limits maximum available chiller cooling capacity in fixed steps to
limit electrical demand.

-   Lighting Control Program

Turns lights off based on the time of day and the day of the week,
including holidays.

-   Digital Totalization

Accumulates values based on contact closures from digital input ports.

-   Field Interface Device (FID) Software

Enables all applications programs to be FID-resident and operate in
stand- alone mode out of the FID.

**Utility Control System (UCS) Overview**

-   Central system in Building 4250 manned continuously around-the-clock
    to provide remote monitoring and control of facilities environments
    at MSFC.

-   Two Hewlett Packard A900 central computers in Building 4250
    communicate over twisted-pair dedicated data lines with 130
    computerized Field Interface Devices (FIDs) located respectively in
    88 buildings at MSFC.

-   Central software is Dorsett Infoscan and Hewlett Packard RTE-A.

```{=html}

```
-   System is focal point for expansion of Direct Digital Control (DDC)
    technologies at MSFC. All DDC software control-algorithms are
    developed through the UCS.

-   Approximately 10,000 analog and digital points interfaced with the
    system.
