Example: AHU control optimization
In combination with a suitable supervisory room controller, an AHU control optimization algorithm can be run using the actual value of the damper position feedback signal.
The control of variable speed drives (VSDs) can be accomplished by various means. Below depicted is DC 0...10 V control, but plants with BACnet MS/TP- or Modbus RTU-controlled VSDs are also possible, depending on the connector layout of the universal / primary controller.

N1 Room unit with temp. sensor
N2 VAV Compact Controllers (supply / extract air)
N3 Universal / primary controller
N4 Variable Speed Drives (VSD)
