7.2 VRV Discovery Issues
No VRV Devices Discovered
VRV Addressing
Every VRV indoor unit must be assigned a group address and an airnet address at the local controller. Every outdoor unit
must be given an airnet address at the unit. Make sure that all devices have been addressed correctly.
VRF Adapter Issue
Check the LED lights on the front of the VRF Adapter.
• Power: No light = No power to the adapter. Check power source to USB expander
Green = Powered on
• RxTx: No light = No data on DIII-Net bus. Check units are on and active
Blinking Blue = Data present on DIII-Net bus
• ERR: No light = Normal
Solid Amber = Power issue or data inconsistency. Check power supply at USB expander
Blinking Amber = Data collision. Check VRV system wiring
Correct and Active Port
Make sure the port you are using for DNET discovery is active. In the Hub UI check in Network > Interface. Active
ports are denoted with a green circle. Turntide VRF Adapters will be connected to USB ports, generally usb1.1 - usb1.7,
corresponding to ports 1-7 on the USB expander. If the port is not green and the VRF Adapter is powered, make sure the
USB connection between the Hub, USB Expander and VRF Adapter are secure.
