Systems
Tracer SC supports three system applications:
• Area
• Variable Air Systems (VAS)
• Chiller Plant Control (CPC)
Area Application
Area is an application that resides on theTracer SC.The primary function of Area is to coordinate
the start and stop of equipment based on a schedule stored in theTracer SC. An Area may consist
of a single room, a group of rooms, a large open warehouse, a manufacturing space, or any
grouping defined by a system user. Area allows such functions as synchronizing member setpoints
and controlling a large number of devices to be performed as one efficient operation.
Area can be configured to use multiple algorithms, along with area temperatures and humidity
inputs, to make an economizing decision.
Area also supports:
• Optimal start/stop
• Humidity pulldown
• Night purge
• Unoccupied heating/cooling setpoints
• Unoccupied humidify/dehumidify
• Timed override functions
Variable Air Systems (VAS) Application
The variable air system (VAS) coordinates the control of air handlers, rooftop units, and variable
air volume terminal units.TheTracer SC VAS includes valuable tools to help manage tasks that
were previously problematic and time consuming, such as:
• Coordinating AHU and VAV box operation
• Commissioning VAV boxes
• Scheduling common spaces
• Optimizing ventilation
• Optimizing duct static pressure
Chiller Plant Control (CPC) Application
The Chiller Plant Control (CPC) application coordinates chillers and provides system chilled water
control.
The CPC application allows you to configure a chiller plant for optimal efficiency and reliability, and
provides a means for you to monitor and control the daily operation. Depending upon the many
possible chiller plant configurations and design differences, the CPC application can:
• Provide overall chiller plant status information and alarms to local and remoteTracer SC users.
• Enable or disable chiller plants.
• Start, stop, and monitor the status of system chilled water pumps.
