Applications
Applications are an important part of the energy management capabilities of your
system. The applications that you can incorporate into the operation of your system
include:
Adaptive Control
Alarm Management
Daylight Saving Time
Equipment Scheduling
Loop/Loop Tuning
Start/Stop Time Optimization (SSTO)
Time and Calendar (schedules, Daylight Saving Time)
Trend Data Collection
User Access and Privileges
Adaptive Control
Adaptive control is a closed loop control algorithm that auto-adjusts to compensate for
mechanical system/load/seasonal changes. It is designed to eliminate the
compromises of traditional Proportional, Integral, Derivative (PID) control. When
compared to traditional PID control, adaptive control provides more efficient, robust,
fast, and stable control. Adaptive control achieves superior performance in a dynamic,
non-linear system in terms of response time and holding steady state, while minimizing
error, oscillations, and actuator repositioning.
NOTE:
Adaptive Control is now a licensed feature for new field panel purchases with
Firmware revision 3.5.1 / 2.8.18 and higher.
Alarm Management
An alarm is a status that indicates whether a point value or state is above or below a
defined value. Alarm management is the strategy used to define, route, acknowledge,
and resolve those alarms.
Points are defined as alarmable for the following reasons:
To prevent critical problems. Points that affect human safety or can cause a severe
problem in building operation should be defined as alarmable. For example, an
alarm that notifies you that the temperature of a heating coil is too low and action
must be taken before it freezes.
To notify you when equipment is not functioning properly. Sometimes problems
may occur and go unnoticed. Alarming is a useful tool to identify equipment that is
not working properly and to prevent other devices from becoming damaged.
To announce scheduled maintenance. For example, an alarm can notify you when
it is time to change air filters.
