Functionality / application
3.1
Fields of application
VAV compact controllers are primarily used for controlling a variable or constant air
volume flow.
System environments:
∂ Building automation systems using the Siemens peripheral bus PL-Link
(Desigo Total Room Automation)
∂ Building automation systems using KNX LTE-mode
(Synco 700 Series C and newer)
∂ Building automation systems using KNX S-mode (third-party integration and
freely programmable devices)
Application fields:
∂ Supply air control
∂ Extract air control
∂ Supply/extract cascade control with
– Ratio control 1:1
– Ratio control (positive/negative pressure)
– Differential control (positive/negative pressure)
∂ Air dampers with a nominal torque of up to 5 or 10 Nm
VAV compact controllers are not suitable for environments where the air is
saturated with sticky or fatty particles or contain aggressive substances.
3.2
Equipment combinations
VAV compact controllers are KNX-certified and may be connected to all KNX
devices with compatible S-mode data points.
