Parameterization of the VAV application The OEM generally provides the basic configuration to VAV compact controllers, especially the parameters for nominal flow (Vnom), the opening direction, and the box coefficient (Vn). The setting of all other parameters depends on the actual application and is usually defined by the ventilation planner or the systems integrator. The following parameters must be checked or set prior to commissioning: 3) Value used for displaying / not used for volume flow control loop Operating mode “Volume flow control” Variable air volume (VAV) control The operating point...

The following parameters are usually checked and set by the systems integrator to achieve the right level of bus traffic generated by the actuator or to define the behavior in case of communication interruption. Parameters in the group “advanced” can be left unchanged unless a special configuration is required. Parameter group “Standard”: Parameter group “Advanced”: Siemens Building Technologies

Notes Safety Caution National safety regulations Failure to comply with national safety regulations may result in personal injury and property damage. ● Observe national provisions and comply with the appropriate safety regulations. Mounting ● Do not open the damper actuators ● Do not use the accessory mounting holes for fixation of the damper actuators Mounting positions IP54 protection in following mounting positions Accessory mounting holes Not to be used for fixation of the actuator, use anti-rotation-bracket instead. Maintenance The damper actuators are maintenance-free. Disconnect the electrical...

Internal diagrams The VAV compact controller is supplied with two prewired connecting and communication cables. All interconnected devices must be connected to the same G0. G..B181.1E/KN The operating voltage at terminals G and G0 must comply with the requirements under SELV or PELV. Safety transformers with twofold insulation as per EN 61558 required; they must be designed to be on 100 % of the time. Siemens Building Technologies
