Operating modes Volume flow control (VAV or CAV) Variable air volume (VAV) control: the operating point is determined by the setpoint value and the Vmin / Vmax settings (cf. diagram below). Constant air volume (CAV) control is achieved by sending a constant setpoint or by setting Vmin = Vmax. Vmin [%] Vmax [%] 1 Setpoint range 2 Actual value range 3 Controlled area 3 Position control The VAV compact controllers can be operated as damper actuators, i.e. using the 0..
Parameterization of the KNX integration KNX integration parameters are checked or set during engineering and commissioning in the ETS engineering tool. Parameter Range Description Factory settings VAV / POS VAV: setpoint = volume flow 0…100% VAV Tab card “standard” Operating mode POS: setpoint = damper position 0…100% Adaptive positioning On / Off Adaption of actual (if mech. limited) opening range Off to position feedback 0...100% 1) Off = No adaption / On = Pos.
