Application example 3: AHU 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. This application is available e.g. with Synco 700 RMU7x0B
(Series C or newer) universal controllers (as depicted below) or in Desigo PL-Link
environments.
The control of variable speed drives (VSDs) can be accomplished by various
means. Below depicted is DC 0...10 V control, but plants with USS- or Modbus-
controlled VSDs are also possible, depending on the connector layout of the
universal / primary controller.
