The FLN Controller provides stand-alone DDC to
deliver precise HVAC control, and comprehensive
information about system operation. The Controller
Board processor receives information from the FLN
devices in the building, processes the information, and
through the FLN Controller devices, directly controls
the HVAC equipment. The following routines are
available in the FLN Controller:
• Closed Loop Proportional, Integral and Derivative
(PID) control
• Advanced loop tuning algorithm for (PID)
parameters
• Logical sequencing
• Alarm detection and reporting
• Reset schedules
Built-in Energy Management
Routines
The following routines are programmed in the FLN
Controller and require simple parameter input for
implementation:
• Peak Demand Limiting
• Start-Stop Time Optimization (SSTO)
• Time-of-Day and holiday scheduling
• Duty cycling
• Equipment optimization and sequencing
• Economizer control
