VRF-VAV Overview

providing the benefits only

VRF-VAV is an innovative concept in air delivery providing the benefits of VAV with the efficiency of VRF HVAC Systems using pressure independent self-balancing Smart Air Valves (SAVs) to enhance VRF operation. VRF-VAV eliminates multiple indoor units, refrigerant lines, condensate line, electrical to simplify and streamline VRF installations. Zonex SAVs control an indoor fan coil’s air flow while respective VRF manufacturer’s outdoor and indoor units control and manage the refrigerant flows. The Zonex system is controlled by the GEN XV controller, our mobile app provides remote internet access and control of all fan coils, SAVs, thermostats & other controls onsite or remotely over the internet ANYWHERE. The GEN XV controller communicates with the indoor unit or fan coil through the VRF manufacturer’s 24V thermostat interface.  This interface accepts standard thermostat inputs, which reside on the GEN XV controller, and converts standard 24V legacy connections through the interface to provide VRF protocol from the information the Zonex system reports and instructs the fan coil to initiate.

GEN XV controls 2-20 independent Smart Air Valves (SAV) per fan coil. SAVs intelligently operate like an indoor unit without affecting VRF operation in anyway. GEN X RMV controllers are used to expand the system to control multiple zoned or stand alone fan coils remotely. GEN XV can support up to 20 RMV expansion controllers providing control of up to 400 units, SAV or other control points. The GEN XV controller is designed for Auto Changeover, VAV operation.
