www.belimo.us VAV-Compact MOD • 2020-03 • Subject to Change Product informationVAV-Compact MOD A pressure sensor, digital VAV controller and damper actuator all in one, providing a compact solution with a communications capability for pressure-independent VAV and CAV systems in the comfort zone • Control modulating, communicative, hybrid • Conversion of sensor signals • Communication via BACnet MS/TP, Modbus RTU, Belimo MP-Bus or conventional control • Service socket for operating devices Product Features Application The digital VAV-Compact has PI control characteristics and is used for pressure-independent control of VAV units in the comfort zone. Pressure measurement The integrated D3 differential pressure sensor is also suitable for very small volumetric flows. The maintenance-free sensor technology enables versatile applications in the comfort zone: in residential construction, offices, hospitals, hotels, cruise ships, etc. Actuator 2 different actuator variants (45 or 90 in-lb) are available for different VAV unit structures. Control function Volumetric flow (VAV-CAV) or Open-Loop (for integration in an external VAV control loop). VAV – variable volumetric flow Demand-dependent setting of volumetric flows V minmax on a modulating reference variable via Modbus, e.g. room temperature / CO2 controller, DDC or Bus system, for energy-saving air conditioning in individual rooms or zones. DCV – Demand Controlled Ventilation In higher-level BACnet / Modbus system, for example with integrated optimiser function. Mode of operation The actuator is fitted with an integrated interface for BACnet MS/TP, Modbus RTU and MP-Bus, it receives the digital positioning signal from the upper system and returns the current status. Converter for sensors Connection option for a sensor (active or with switching contact). In this way, the analogue sensor signal can be easily digitised and transferred to the bus systems BACnet, Modbus or MP-Bus. Parameterization The factory settings cover the most common applications. As desired, individual parameters can be adapted for specific systems or servicing with a service tool (e.g. ZTH US). Communication parameters The communication parameters of the bus systems (address, baud rate, …) are set with the ZTH US. Pressing push-button "Address" while connecting the supply voltage resets the communication parameters to the factory setting. Quick addressing: The BACnet and Modbus address can alternatively be set using the buttons on the actuator and selecting 1 to 16. The value selected is added to the «Basic address» parameter and results in the effective BACnet and Modbus address. Combination analog - communicative (hybrid mode) With conventional control by means of an analogue positioning signal, BACnet or Modbus can be used for the communicative position feedback Operating and service devices Service tool ZTH, PC-Tool service socket: locally pluggable or via PP connection. Electrical connection The connection is made with the integrated connection cable.

The actuator then moves into the required position in order to ensure the volumetric flow defined by the positioning signal. 5) See www.belimo.us for function and version history.VAV-Compact MOD Volumetric flow compact control device for BACnet / Modbus www.belimo.us VAV-Compact MOD • 2020-03 • Subject to Change Quick addressing 1. Press the "Address" button until the green "Power" LED display is no longer illuminated. The green "Adaption" LED display flashes in accordance with the previously set address. 2.
