• Supply/extract cascade control with
– Ratio control 1:1
– Ratio control (positive/negative pressure)
– Differential control (positive/negative pressure)
VAV compact controllers are not suitable for environments where the air is
saturated with sticky or fatty particles or contain aggressive substances.
In critical cases material compatibility tests should be made while considering
harmful substances and concentrations.
